(The rest of this has nothing directly to do with Fedora)

I do this with Phillips Hue lights and Home Assistant. The Hue integration
in Home Assistant communicates directly with the API on the Hue bridge, so
the lights can be controlled without the cloud.  The lights don't actually
use WiFi, they communicate with the Hue bridge directly (using a wireless
protocol but not IP). There is a pre-made Raspberry Pi 4 image for Home
Assistant that works quite well. It might be overkill to set up Home
Assistant just for a few lights, but I use it for a number of other devices
as well (some of which do require the cloud, but I chose to use it knowing
that). Home Assistant also has programmable automations so I can do things
like turn on the porch light at sunset and so forth. There is a Home
Assistant phone app, but it also can be configured via a web browser so you
don't HAVE to use the phone app.

 And I've heard tales of ambulances coming

The Hue bulbs I have can be operated by the normal light switch. When
automating, the switch is on all the time, but turning the switch off and
back on makes the light come on full power, and then switching it off again
of course turns it off. Of course the automations no longer work if the
light has been powered off, but this isn't going to be a great concern if
it was powered off by a paramedic coming to the house :-)  In fact the
worst problem is if there is a power outage, when power is restored all the
Hue lights come on. Power outages are quite rare here, and if there is one,
I can turn the lights off again remotely using Home Assistant.

I think the chances of the relatively low power Hue bulbs being the cause
of a fire are quite remote.

Re: [SOLVED] LibreOffice Base to MariaDB?

[Greg Woods]

After installing the "unixODBC" and "mariadb-connector-odbc" packages, I
finally found this:

https://mariadb.com/kb/en/creating-a-data-source-with-mariadb-connectorodbc/

After following the directions there for setting up a data source and
running the "odbcinst" commands from that document, I got it to work.

LibreOffice Base to MariaDB?

[Greg Woods]

I remember setting this up quite some time ago, but now I have a new
machine running F38. I can find some documentation for the old very tedious
procedure to get this to work; it still does work on an older machine where
I had done this. But I notice now that Fedora might already have some of
the required packages, such as mariadb-connector-odbc-3.1.19-1.fc38.x86_64
and unixODBC-2.3.11-2.fc38.x86_64 . Would these packages work? Has anyone
here already gotten LibreOfficeBase to talk to a MariaDB database on Fedora
38? If so can you point me to a place that describes the process for
getting it working?

Thanks in advance,

  I use "gparted" for this ('dnf install gparted'). It seems to work quite
well on Windows NTFS file systems and partitions. I have successfully used
gparted on ext4 and xfs partitions as well, but I have never tried it on
btrfs.

Re: F38 and NUT -- SOLVED

[Greg Woods]

FINALLY! It occurred to me to try this:

So it seems that an edit to ups.conf was also needed. Commenting out the
maxtry line (which has been there literally for years) gets things working
again. Thanks again to Robert and Jeff for pointing me in the right
direction.

Looks like I spoke too soon; I noticed that the nut-monitor service had
stopped running. I restarted it, and:


Apr 27 09:52:26 seveneves.gregandeva.net nut-monitor[11136]: Poll UPS

This is being logged every 5 seconds. So I'm more-or-less back to square

Sorry for any confusion, my bad. The subject line should read "F37 and
NUT", consistent with the Fedora versions mentioned in the original post.

F38 and NUT

[Greg Woods]

Since upgrading to F37, I am having problems getting Nut to work properly.
The errors I get from the journal are:

Apr 26 17:01:42 seveneves.gregandeva.net nut-server[326151]: Can't connect
to UPS [seveneves-ups] (usbhid-ups-seveneves-ups): No such file or directory

Apr 26 17:24:00 seveneves.gregandeva.net nut-monitor[326253]: Poll UPS
[seveneves-ups@localhost] failed - Driver not connected

All I could find on the net suggested that "Driver not connected" means I'm
using the wrong driver, but this is the identical configuration (including
the driver) that worked in F36. It's also a nearly identical configuration
that is still working for an identical UPS unit monitored from a Raspberry
Pi running Raspbian.

Any Nut gurus here that could help me troubleshoot this, and has anyone
else seen Nut quit working on F37 using a configuration that worked with
F36?

Here's what I have in my config files:

nut.conf:MODE=netserver

Re: openvpn3 on F37

I didn't change anything else, but now the authentication is working. I
still don't know why it was failing consistently but now it works. The real
issue was the need to install the openvpn3-client package.

Made some progress with more careful examination of the systems where it
works and where it doesn't, and it turns out that there is also an
openvpn3-client package that has to be installed as well as openvpn3. This
didn't occur to me because the openvpn3 client binary was installed. But
when I installed openvpn3-client, the missing binary for the session
manager was installed. So now I can get a little farther; I just need to
figure out why user authentication is failing (I've tried it on the old
system so I can verify I have the correct user name and password, and I
have tried it enough times on the new system to rule out simple password
typo as the cause). So now I can execute the session-start command, and it
does prompt me for the username  and password, but always returns
authentication failure.

openvpn3 on F37

[Greg Woods]

First let me say that I am aware that openvpn3 is not an official Fedora
package; one must obtain it from a COPR repo. Therefore I could not file a
bug against it in Fedora and in fact I don't know how I COULD file an
official bug report, so I am just hoping that someone here has it working
and could help.

I have had openvpn3 working since F35, including on a laptop that I
originally installed openvpn3 on and it has been upgraded to F36 and now
F37, and openvpn3 is working fine.
However, on my new laptop with a fresh install of F37, I cannot get
openvpn3 to work. The config manager seems to be OK, but the session
manager is totally broken. First I import my config, and then:

[greg@ivanova ~]$ openvpn3 config-import --config /local/etc/OVPN.ovpn
Configuration imported.  Configuration path:
/net/openvpn/v3/configuration/f75863b0x38dcx4ea5xa36ex35936d9cc4df

Re: Native Windows to qemu-kvm?

[Greg Woods]

A problem you could run into doing this is licensing. WIndows uses a
variety of methods to detect if a valid product key is being run on
multiple machines, which includes some checks on the hardware. Since a
virtual machine is never going to have virtual hardware that exactly
matches your PC, there's a good chance that, even if you succeed in getting
your native install to run under a hypervisor, Windows may well consider it
an unlicensed copy.

I recently had a Windows 10 VM that this happened to when I just upgraded
Virtual Box, didn't touch the Windows VM at all.

However, it does matter which exact product you have, not just whether it
is a quality product or not. For instance, I have a really nice pair of
Bose bluetooth headphones. They sound great, but unfortunately they only
work on my Android devices, because they require use of an app to properly
connect. They will not reliably pair with Linux or Windows.  (There is
probably an iPhone version of the app too). Same holds for my pair of Sony
"true wireless" earbuds. Sound great, but will not pair with a computer,
require an app.

I would dispute that. In my case, caddy runs on an internet-accessible
server, but the actual web server is behind two firewalls. The unencrypted
connection is entirely behind at least one firewall, and if someone manages
to gain access to the inside of that firewall, then the game is already
over. I don't think I'd recommend this for enterprise setups, as there are
too many potential threats already behind the firewall (can you really
trust every single one of your employees?) But for a home setup where the
only authorized users are my wife and myself, I think it's sufficiently
secure. But everyone will have to judge that for themselves.

One other possibility is to do what I do, and run a reverse proxy such as
caddy. Caddy will take care of the annoying renewals automatically, accept
connections via HTTPS and forward them on to your web server via HTTP. It
can be a bit tricky to configure initially, but it works a treat.

networked sound via pipewire

[Greg Woods]

Is this actually possible right now? Pipewire is under rapid development
which means the documentation out there on it rapidly becomes dated, so
I've been poking around for the past hour but haven't found anything that
would help me do what I want.

What I want to do is have some of my virtual machines send their output
over the network to my desktop. Not having audio from the VMs is limiting
what I can do with them. Can this be done with pipewire as it stands now?
Is it documented anywhere?

OT: ink jet printers

[Greg Woods]

Well, not completely OT because I do need one that will work on Fedora.

I have found a number of ink jet all-in-ones that work well on Fedora, from
Epson, HP, and Brother. The problem is that I don't use the printer all
that much, and every single one of them eventually (after I've had it for a
few months) develops a head clog that is so bad that not even the printer's
cleaning cycle can fix it. I have tried some of the cleaning kits with not
much success (I'm a lousy handyman), and even if I could get the cleaning
kits to work, I'd rather find a printer where I can avoid this headache.

So, is there any such thing as an all-in-one ink jet printer that does not
suffer from this problem if it is not used regularly? Question #2 is, are
any of the all-in-one laser printers any good and work (all functions) with
Fedora Linux?

I would bet that if you "cat /proc/cmdline" you will see a resume=

already occurred when the resume is attempted:

Interesting; on my F34 system, the message mentions nm-run.service rather
than nm-initrd.service. Neither nm-run nor nm-initrd exist as services, but
something is calling systemd-udev-settle although it only takes 2 seconds
to run and exit, so I never noticed this before.

Dell likes to configure the SSD as a RAID in the BIOS. Even though their
Windows installation is not using it as a RAID device.  When it is set to
RAID in the BIOS, Linux cannot see it. For Linux to run, it must be set to
AHCI mode. In my relatively new Dell workstation, this is under System
Configuration -> SATA Operations.

It "should" be safe (all I can say is that it was for me) to go in and
verify that your SATA mode is set RAID (in which case this is likely the
cause of your problem), set it to AHCI, and then boot your Linux USB stick.
It should then see the SSD.

Unfortunately, Windows will now not boot unless you change it back to RAID.
If you were planning to keep the installed Windows system (which I wanted
to do), then there is a procedure you can Google for (it might have even
been referred to on this list) that will allow the Dell-installed Windows
to boot in non-RAID mode. I followed the directions and can now dual boot
Windows and Linux out of the GRUB menu.

In my experience, there are some artifacts (someone earlier referred to it
as "trippy effects") around the edge of the person's head. And in any case,
this feature is not available in the Linux version of Zoom. I don't know
whether any of the other suggestions made in this thread might work or not,
but the only way I successfully got background image to work in Linux Zoom
was to use a green screen behind me. And no trippy effects.

I looked into this with Zoom, because I wanted to have a nice background
like my online bridge partner does. It turns out that Zoom does have a way
to separate foreground from background that does not rely on a green
screen. It mostly works although there are a few artifacts. However, this
feature is only available on Windows. If you are running it on Linux, you
need a green screen in order to use a virtual background.

I use an old slide projector screen with a green cloth draped over it. It
works well but is a pain to set up for every Zoom call.

I did manage to figure this out. I have to give a shout out to the Arch
Linux people for doing an excellent job on their documentation. I
frequently find things in there that help with my systems (all Fedora or
Raspbian) even though I don't actually run Arch except in a VM for playing
around and learning. I found their suspend and hibernate page at
https://wiki.archlinux.org/index.php/Power_management/Suspend_and_hibernate
to be very helpful. Arch uses something called "mkcpio" rather than
"dracut" that Fedora uses, but the main thing it mentions is the need to
rebuild the initramfs image to include the "resume" module. That works! And
my Dell desktop will now hibernate. The command was just "dracut --add
resume" (I first saved a copy of the current img file just in case). I find
it interesting that I have been using hibernation on Fedora for years and
never had to explicitly do this. I just checked my main Fedora server, and
"lsinitrd" shows that there is no "resume" module in the initramfs file.
But I have never tried hibernating the server. My laptop *does* have the
resume module even though I never explicitly included it. There is nothing
I can find in /etc/dracut that specifies that the resume module should be
included, but it is there. There is still a lot about how all this works
that I don't understand.

And to my embarrassment, I found a previous reference on this list to using
dracut to add the resume module for hibernation, but it did not come up in
my previous searches of my archived list messages. In there it is suggested
that perhaps the resume module was only added in by default if you create a
swap partition at install time, but I always do that so I'm not quite sure
what happened this time.

I don't use Secure Boot on my desktop or my servers because it makes too
many things a lot more painful (like third-party drivers such as nvidia)
and since these systems never leave my house, the security risk is minimal.

Dell seems to be the "culprit". I have a Dell desktop where I had almost
the same problem, except it was only with the NVME drive. If the BIOS was
set to RAID mode, Windows boots and runs normally. Linux will also boot and
run, since it is installed on a separate non-NVME drive, but it can't see
the Windows partitions, which unfortunately includes /boot/efi. So I can't
do any kernel updates (and who knows what else) unless I manually set the
SATA mode to AHCI in the BIOS, in which case Linux will boot and see all
the drives, but Windows will not boot. This has led to the very annoying
position of having to fiddle with the BIOS every time I want to switch
OS's. I'll try the process in that article. Thanks for the pointer!

Now if I can only figure out why this damn machine won't resume from
hibernation properly. Windows can do it, so I'll bet it's a configuration
issue somewhere.

A lot of the big providers have made doing this far more difficult than it
used to be. I have personal experience with Gmail, where I used to be able
to highlight part of the message, and that was all that would be included
in my reply, but that no longer works; the entire message is included and I
have to manually trim it.  Gmail also top posts by default, which may also
account for the increased amount of top-posting we see, particularly if
other large providers are working the same way. In short, it takes a lot
more work than it used to take to do interspersed replies, but it is still
possible if you climb the learning curve and put in a little effort.

Yes. The format is  "Got automount request for /pub, triggered by #PID#
(#command#): 1 Time(s)

I suppose I should provide more info. /pub is a place where I store a bunch
of stuff. In particular there are our photo and music collections, and
rsync'ed Fedora repos (I rsync F32 and F33 repos once a day, then I use the
local repo to perform updates on my 6 Fedora systems).

The problem here is that, by the time I see one of these entries and
investigate, the PID is for a process that is long gone, and I'm not
getting any useful info about what command is triggering this.

As an example, here is a message that is the result of a known access
(doing a "dnf update"):

pub.automount: Got automount request for /pub, triggered by 253560 (dnf): 1
Time(s)

Again, process 253560 is long gone, but at least I know that this automount
was triggered by a dnf command. When the command is "PT3122", then I have
no clue what triggered this automount. And the vast majority of these
automount triggers do not have useful information about what command
triggered it. I guess what I really want to know is if there is anywhere I
can look for more information, or in general if there is any way to
investigate this.

The machine that is producing these logs is my main Fedora server. It is
NOT the server for the /pub disk, that is on a Raspberry Pi (NFS-mounted
from that Pi server to this one), so these aren't NFS accesses from another
system. If I look at my desktop system, which also automounts /pub from the
Pi server, all of the similar entries do specify the command, for example
"journalctl | grep /pub" snippet:

Dec 14 12:08:23 snowcrash.gregandeva.net systemd[1]: pub.automount: Got
automount request for /pub, triggered by 1189068 (k3b)

Dec 14 12:09:24 snowcrash.gregandeva.net systemd[1]: Unmounted /pub.
Dec 14 16:24:26 snowcrash.gregandeva.net systemd[1]: pub.automount: Got

Dec 14 16:25:27 snowcrash.gregandeva.net systemd[1]: Unmounted /pub.

I do not see any entries that just list PT as the command on the
desktop system. On the server, almost all of them are.

automount requests

[Greg Woods]

My logwatch each day has dozens of messages like this:

pub.automount: Got automount request for /pub, triggered by 242640
(PT3122): 1 Time(s)

I want to determine why this is happening, because the drive
containing /pub (on a different machine mounted via NFS)  is spun down when
idle, and these events are likely causing it to spin up. My understanding
is that the part inside the parentheses is the command name of the process
that triggered it, but I don't know what the "PT" syntax means.

Thanks for any info,

No and no. I have a separate swap partition. My file systems are NTFS (dual
boot with Windows 10), vfat (EFI partition). The Fedora file systems are a
combination of xfs and ext4.

That should only happen if the "forward only" option is used. That's how it
worked when I used to run DNS for a medium-sized organization, and it's
still documented that way in named.conf(5).

Re: SPDIF sound in F32

[Greg Woods]

There has been a completely new development in this saga. One thing I had
also been investigating was to see if I could somehow get surround sound
through the onboard Intel sound chip. This chip does not have a iec958
(optical) device however, so it wasn't going to work directly with my
receiver. As a temporary workaround I was attempting to at least get stereo
sound going through the line out of this chip, and it was not working,
despite the fact that it worked fine on another machine in the house with
an identical motherboard. Then I remembered that the UEFI has settings for
the onboard devices, and by default the onboard audio is set to "Auto",
which it turns out means Enabled unless there is a sound card installed. So
that's why it didn't work on the machine with the Xonar card installed. I
changed it to Enabled and I got stereo sound. I can also now see four
separate HDMI sound devices in aplay. So I played around with some of the
things I have learned recently, and it turns out that this chip can do
surround sound via HDMI, and since the TV that the system is hooked up to
can pass that on to the receiver, I decided to try it, and it mostly works.
I say "mostly" because when I run the 5.1 surround sound test in MythTV, it
does front left, center, front right just fine, but "surround right" means
both rear speakers at reduced volume, and "surround left" means both rear
speakers at normal volume. That's of course not how surround sound is
supposed to work, so I still have a few things to look into there
(including things like settings on the TV).

So I'm still interested in trying to get the iec958 device on the Xonar
card to work, because I expect I'd get better quality sound that way, but
the urgency is reduced.

I wanted to use "cset ... unmute", because the iec958 device seems to be

compo‐
  nents: iface, name, index, device, subdevice,  numid.  The

...but I couldn't figure out correct values for all these components. My
attempts always got:

amixer: Cannot find the given element from control default

Using DEV=1, I get:

 [mythtv@seveneves ~]$ aplay -vv -D iec958:CARD=SoundCard,DEV=1
/pub/flac/music/rock/CDs/Country_Joe/CollectedCountryJoe/CCJatFT05.wav
aplay: main:830: audio open error: No such file or directory

Using -vv on the DEV=0 version does show the "meter" with the pound signs
bouncing up and down, so it thinks it's sending something. But the optical
cable is not lit. I did check the obvious and the stupid, and it does
appear to be fully seated into the card. While I was at it, I also tried
using a different optical cable that I know is good, but still no sound.

Turning them all up in alsamixer was the first thing I tried. They are all

That is not an encouraging sign, but I have learned more about how this

lot I don't know.

Funny, I thought of this as I was going to sleep last night. I guess it's
evidence that I spent too much time on this yesterday and got too
frustrated; my brain was not working very well. I should have thought of
that much earlier.

The card is an ASUS Xonar SE

I also found alsa.opensrc.org that has some helpful stuff, especially the
DigitalOut section, but it's going to take me a while to understand all of
it.

So "aplay -L" does actually show an iec958 device; MythTV had to be getting
it from somewhere. This gives me some hope that it might be possible to
eventually make this card work.

In "pavucontrol", it actually does have a listing for the Xonar Sound Card,
but only the analog output port is available. In alsamixer, I can press F6
to select sound card, and "Xonar Sound Card" is a selection, but there is
no iec958 device.

But it actually is a PCIe x1 card.

If I get into the audio settings in MythTV, it will show the iec958 device,
but setting the audio to use it produces no sound.

That's true for stereo sound, but not so true when you try to use surround
sound and iec958 devices.

SPDIF sound in F32

[Greg Woods]

After wrestling all day with an ASUS Xonar SE card (with accompanying
Googling), I now believe that this card cannot be made to work in Linux.
Stereo output through the green line out port works fine, but SPDIF does
not. "lspci" actually claims this thing is a USB controller, although as I
mentioned stereo sound does work.

Does anybody have a PCIe sound card that is known to work with SPDIF 5.1
surround sound output? It has to be optical as those are the only digital
ports on my receiver.

One frustrating thing about trying to search for information online is that
I come up with a lot of stuff that is way too old to be useful. For
instance, a lot of the advice articles I found on getting sound working
mention 4Front and OSS sound drivers, which is probably 15-20 year old
information. I'm looking for  first hand "yes I know this card works", or
at least a pointer to something that isn't Ubuntu specific and is recent
enough to be useful.

Thanks,

Xbox 360 controller on Fedora 32

[Greg Woods]

It has been a couple of years (which means 4 or 5 Fedora releases ago)
since I did this, but I used to be able to play Xonotic using my Xbox 360
Wireless controller. Now I cannot get the controller to work properly in
F32 (it works in Windows 10 so I know the hardware is OK).

This most likely has something to do with the move from xboxdrv (which is
no longer available in Fedora) to xpad kernel driver, and/or the move from
the old js driver to evdev. The xpad driver comes with the current kernel,
but what I cannot figure out is how to calibrate the controller. If I run
Xontic with the controller connected, the game  world just spins
counterclockwise. This is a symptom of the controller needing to be
calibrated, but I don't know how to do it. I tried using "jscal", but if I
run "jscal -c" to calibrate it, it appears to work but doesn't. I can
immediately run "jscal -t" and it will say it is not calibrated, and
running "jstest" also shows it is not calibrated (several of the axes are
not centered, i.e. show nonzero values in jstest).

I attempted to download and compile xboxdrv, but it does not work due to
Python 2 vs. 3 incompatibilities, and it doesn't look like any work has
been done on xboxdrv in quite some time. If I try to make it, I get this:


root@snowcrash xboxdrv-linux-0.8.8]# make
scons
scons: Reading SConscript files ...
  File "/local/src/xboxdrv-linux-0.8.8/SConstruct", line 34

print target

  ^

SyntaxError: Missing parentheses in call to 'print'. Did you mean
print(target)?

make: *** [Makefile:24: xboxdrv] Error 2

Certainly looks like Python version incompatibility.

Can anybody point me to information on how to use an Xbox 360 controller on
F32, or how to calibrate it when using the xpad driver? I have done a lot
of Googling, but most of the articles I found mention things like "apt-get
install xboxdrv", showing they were written for Ubuntu rather than Fedora
and are wanting to use the xboxdrv driver.

Thank you,

UPDATE: one or two times when I switched away from the dual monitor system,
I got  a green screen on the second monitor, and when switching back to the
problem system, both monitors were green screened and the keyboard and
mouse were unresponsive. It required an SSH in from another system
to suspend the machine; on resuming, things were working again. But this
raised the level of the issue from "very annoying" to "show stopper".

I realize nobody reading this now cares about this (presumably that just
means nobody else has a dual monitor setup with one monitor controlled
through a KVM switch, or else those who do haven't seen this happen and
don't have any ideas).

But I'm posting this in case anyone finds this in the archives later. I am
now convinced the issue all along that the graphics driver for my card,
which is one of the "Republic of Gamers" (ROG) intended for serious gamers,
is the cause (ROG is just an ASUS marketing term).  I have spent a lot of
time Googling around and finally found a proprietary driver that ASUS
produces. It is intended for EL8 and derivatives (e.g Centos 8), and will
not install directly on Fedora, as the necessary packages (which have names
that begin with "amdgpu") are not in the EPEL repo for Fedora. However, I
downloaded the driver software for Linux from

https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-20-10


and then followed the guide I found at

https://www.reddit.com/r/Fedora/comments/hftkwd/guide_install_amdgpupro_opencl_in_fedora_32/

This installs a part of the driver called "OpenCL"; the kernel device
driver "amdgpu" is still being used. I am not entirely clear on what OpenCL
is, but it adds some features that programs like Blender used; the guide
author reported getting crashes prior to installing the proprietary OpenCL
part (he probably considered that a show stopper too).  For me, I was just
in desperation mode to solve my issue, but this fixed it. Once I installed
the ASUS OpenCL packages, I no longer get the "flashing monitor syndrome"
or green screen lockups.

bizzare dual-monitor behavior

[Greg Woods]

Let me start by saying I have used this same setup literally for years now
and have not seen this new issue until yesterday.

I have a dual monitor setup. One of the monitors is controlled by a KVM
switch; the machines that have only a single graphics port use this monitor
via the KVM switch. The other monitor has two HDMI ports that are connected
to two computers directly, bypassing the KVM switch; I just switch the
second monitor manually between the two as needed.

What used to happen when I switched to a different computer is that I can
use the new computer using the first monitor, the mouse and the keyboard,
just as usual. The second monitor, unaffected by the KVM switch, will
continue to show the image it is getting from the dual-monitor system. I am
used to this; sometimes I even use it to my advantage when the monitor is
showing a web page or something that I can still see while working on a
different computer.

But, what is now happening (since yesterday) is that when I switch to a
second computer, the non-KVM-switched monitor now flashes off and on every
few seconds (and just keeps doing this seemingly forever; I did leave it
this way for more than 15 minutes last night) . This is INCREDIBLY annoying
and makes it impossible to make any use of the image displayed there.

Another oddity is that this is NOT happening with the other dual-monitor
machine. That system is a Dell laptop in a dock. The system with the issue
is a fairly new desktop (which did not exhibit the issue for the first few
days of use, it suddenly started yesterday). Both systems are running
Fedora 32 (but of course they have very different hardware).

I normally use GNOME on Xorg, but I have tried plain GNOME (Wayland) and
Cinnamon too and the problem exists there as well. I briefly tried Plasma,
but that results in a solid green screen, and when I switch back to the
two-monitor system, the first monitor is solid green too and none of the
keys respond, so I had to use a remote ssh shutdown to recover.

Has anyone ever seen anything like this and know what I could do to stop it?

Thanks,

I have found that if you change an fstab entry, after doing "systemctl
daemon-reload", you also may need to restart the automount service to get
the changes to take, e.g. "systemctl restart raid.automount". Whether this
is necessary may well depend on exactly which parameters you specify in
your fstab entry, but I have certainly seen cases where this is necessary.

The obvious as stupid answer is because it is not designed to work that
way. The process is actually documented; see for example
systemd-fstab-generator(8).

I would guess that keeping an eye on dozens of config files to see if any
of them have changed would use a lot of system resources over time, but I
expect there are more serious and less obvious reasons why this is not done.

In fairness to systemd, it has never been possible to edit /etc/fstab and
have your changes automatically applied. It has always been necessary to
run some sort of mount command (or reboot) after modifying fstab.

Re: automatic mount of partitions

I use systemd automounts for this. In /etc/fstab on B, something like this:

A:/path/to/mount /path/on/B nfs
noauto,rw,x-systemd.automount,x-systemd.idle-timeout=1min,x-systemd.mount-timeout=30
0 0

Generally, just accessing anything under /path/on/B will cause the mount to
happen. It will then unmount after 1 minute of nothing accessing
/path/on/B. An attempt to access /path/on/B if A is not available will hang
for 30 seconds, then report a failure to the accessing application.

This works well for me.

Sounds like you might be getting hit by this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1821946

I have been unable to build the DAHDI drivers for 5.5 and newer kernels.
The build complains about a missing include file "classmap.h". The bug
report mentions this occurs just trying to compile the kernel from source,
and also for the VMware drivers, so if this is what is biting you, it's not
specific to the NVIDIA drivers.

Since I just finished going through this, I'll add my 2 cents. Google Drive
didn't work for me, even though I've already got a Google account. This is
because there is no syncing client for Linux, and that's what most of my
machines are. I understand that there is a new 3rd party "Gdrive" client; I
will have to look into that when I get time. Dropbox has recently reduced
the number of allowed devices to 2 without a paid account, which caused me
to start looking at other services. Never looked at NextCloud. My personal
choice was SpiderOak, because they store your data encrypted so that even
their own employees can't see it. So I figured if I was going to have to
have a paid account anyway, I'd use that. The only drawback to SpiderOak is
that the Android client is read-only. This is intentional due to the lack
of security on Android devices, but this could make it a non-starter for
some (such as my wife, who does absolutely everything on her phone; she has
a Linux laptop but only uses it for things where she needs more screen real
estate).  I also use Amazon S3 as an archive, because it is very cheap if
you use the tier where writing is easy but restoring is slower and costs.
But it's good for storing stuff I don't want to lose (such as encrypted
copies of my GnuCash data file, all our photos and videos).

I'm not claiming I know best about all this, just some data points.

 gnome-shell-extension-desktop-icons.noarch
   19.10.2-1.fc31@updates

Installing this extension, which appears to be supported as it is being
updated, creates a button in the tweak tool for turning them on or off, and
a settings sub-menu where the display of the Trash icon can be turned on
and off. Turning  on display of the Trash icon causes none of the icons to
be displayed. The only way I know of to see what is in the Trash or to
empty it is to invoke a file manager such as Nautilus or Dolphin. This
seems to be new in F31, as the icons and the Trash work fine from the
desktop on my F30 system.

Yes, but one of the reasons for using the desktop icons in the first place
is to avoid the extra steps of going into shell mode and using the
keyboard.

In any event, if the desktop icons are no longer supported, and there are
bugs in how they work, then I have little choice but to dump them and move
on, so that is what I have done.

Thanks for that piece of information. That mostly works. It took me a few
minutes to find them under Applications -> Other, but they are there and
the icon images are there as well. It will take me a while to get used to
where they are located now, but I suppose I will eventually get used to it.

I probably should have thought of just uninstalling it. I am getting older
and I am slipping.

Oddly enough, after having been away from the computer for a couple of
hours, when I got back the desktop icons had disappeared again. Even before
I removed gnome-games and without my having done anything in the meantime.
I wonder if they will reappear again the next time I reboot or log out. OK,
so I restarted gnome-shell, and now they have appeared on the secondary
monitor.

In any event, if that really isn't supported any more, I'll just remove
them from ~/Desktop and get used to finding them in the Applications menu.

Thanks,

Desktop files in F31

[Greg Woods]

I just had to replace the SSD in my laptop, which for reasons that would
deserve a discussion thread of their own, I ended up having to do a
complete reinstall. Then I restored all my home directory files. So what I
have is a clean F31, but my own account from the old F30 system was
restored. I am using "GNOME on Xorg" as the desktop environment.

The problem I have is with Desktop files (in ~/Desktop). First I didn't see
them at all, then found with some Googling that I needed to turn off
display of the Trash icon, which now allows me to see the Desktop files.
There are two issues:

1) The desktop icons are visible, but the Icons=file line in them seems to
be ignored.
2) When I double click one, the Exec=command is executed, but it also opens
a full-screen window that I figured out is "gnome-games".

For #1, I first did a little research with dnf and discovered that I needed
to install the "comps-extras" package to bring back the files in
/usr/share/pixmaps/comps . But this did not fix the issue, even after I
restarted gnome-shell (with ALT-F2 and "r"). So I logged out and back in
again, but no joy. I did check to ensure that my account can read the
specified image files.

For #2, I would like to know how I can stop the execution of gnome-games.
With a little trial and error, I discovered that if I iconify the
gnome-games window the first time it comes up, then the Desktop icons
double-click-execute properly, but if I instead kill the gnome-games
window, then it pops up again next time I double-click an icon.

A sample Desktop file is below. Both issues occur whether or not I have the
leading "#!" line.

The settings from after login will only control what happens after the X
server has started. So this is useful for declaring where you want your
panels; that is the "Primary" display.

Which screen has the login prompt is the function of the greeter. In Fedora
by default that is GDM (Gnome Desktop Manager?). I looked through a page I
found searching for "GDM configuration" and didn't immediately see anything
that would allow configuration of which screen the login prompt appears on,
but I could have missed it. It's also possible that other greeters (SDM and
LDM are available) might be able to configure this, but I didn't pursue it
that far.

For the record, I have a KVM switch that allows multiple computers to
connect via VGA to my smaller "secondary" monitor, while the larger
"primary" monitor has a desktop and laptop connected to it by HDMI. I have
a desktop that has an Nvidia PCIE card with DVI and HDMI output ports. The
DVI port uses an adapter and a VGA cable to connect to the switch. On this
machine, the grub menu and the greeter login appear on the VGA monitor.
Once logged in, the panel and desktop icons  appear on the HDMI monitor, as
that is what I configured in the Display settings. The Dell laptop, on the
other hand, only has a VGA port when it is in the dock, and I connect that
to the VGA monitor. The dock also has an HDMI port as does the laptop
itself. On this machine, the grub menu and the greeter login both appear on
the HDMI monitor, as does the Gnome panel.

I use the secondary monitor without workspaces (configurable in the tweak
tool workspaces setting), which means I can put windows there that will
remain visible even when I change workspaces on the primary, but by default
it uses both monitors for each workspace.

That is what I have tested at home and it seems to work. If you want to see

and note the difference.

 And as noted, any home-based filters will fail if they can connect their
phones to some other wi-fi than yours. School networks are probably
filtered, but of course coffee shops and other public hot spots likely are
not.

At work, we used to use OpenDNS to keep porn off our network. Since we
received US Govt. funds, we were required by an Act of Congress to take
steps to keep porn off our network. Obviously no one can check to ensure
there is no porn on every network that receives funds, there were a few
"approved" methods to comply, and OpenDNS was one of them. I think it's
pretty effective in general, as they do a good job of keeping their list of
porn sites up to date. They also block phishing sites (web sites that mimic
real-world sites in an attempt to convince you to give up the private info
they are trying to get), which is (to me at least) far more valuable than
blocking porn.

We of course had an enterprise account, but you can use the service for
free as long as the number of queries you generate is small enough
(probably most home sites would qualify). You can go to opendns.com for
more info.

Not exactly that, but something similar. I have a Logitech mouse that is
connected by a specialized USB dongle (uses Bluetooth, but not the
Bluetooth service on the Fedora box). What I see sometimes is the same
"wheel moves the pointer only in very small increments" that you describe.
Turning the mouse off and back on restores normal behavior.

I have had this happen. I've seen two things that can cause it (and there
are probably more but the fix is likely to be similar): a dependency issue,
and a failure for the GPG key for the target Fedora version to get loaded.
Dependency issues can result from a number of things, such as packaging
errors or use of packages from third party repos. The keys for the new
distro are *supposed* to be installed automatically, but sometimes it
doesn't happen.

At any rate, the first step is to check in /var/log/dnf.log and see if
there is a traceback in there, which will usually point to what the problem
is. In my case I was trying to go from F28 to F29, and ended up having to
remove the "mediatomb" package (which I wasn't using anyway). This is what
I found in the DNF log:

I also had a similar problem with the "createrepo" package which I *do*
use, so in that case I just removed the package, did the upgrade, and
reinstalled it afterward.

For the GPG key issue I saw this:

Traceback (most recent call last):

For some reason the GPG key for Fedora 29 was never imported, so I did it
manually, and finally everything worked.

Re: HP printer device manager not seeing HP printer

[Greg Woods]

I discovered the very hard way (wasting a couple of frustrating hours) that
it is virtually impossible to set up a newer HP printer without running
hp-setup first.

HP M254dw anyone?

[Greg Woods]

Just curious to know if anyone has successfully gotten one of these M254dw
printers to work under Fedora (or any Linux distro for that matter). The
hplip-3.18.12 version that comes with Fedora supposedly supports this
printer; the release notes say support for the M254dw was introduced
several minor versions prior to this one.

However, it doesn't work for me. If I use the recommended Postscript driver
when configuring the printer, then attempting to print images just prints a
Postscript error page, and attempting to print text in duplex results in
only the front side of the first page printing. Needless to say, the
printer works fine under Windows 10, so it's not a hardware issue.

There is a newer version of the driver (3.19.5) that can be downloaded, but
the installer craps out. It first prompts me for the root/superuser
password, but then proceeds to use sudo (which would presumably need MY
password, not root's; trying to give my password results in a complaint
that it is not correct). All the commands where it tries to use sudo report
failure, although if I run them manually, they work. So it is clearly
confused about whether it should be using su or sudo to run commands. This
is obviously a bug in the installer, but HP's "file a bug" link points to
the Launchpad site (where Ubuntu bugs are reported). I don't know if HP
will even see what I posted, and I'll most likely just end up looking like
a dork for posting about a Fedora issue on the Ubuntu reporting site. And
in the end, there's no guarantee that the later version will work any
better than the Fedora-packaged one; it just seemed worth a shot.

I'm mainly curious to know if anyone has this printer working under Fedora,
and if so, how you configured it.

Thanks,
--Greg

Thanks, I will try that when I have time for the next upgrade.

And the reason it says CIFS in the subject when it's an NFS mount is:
senior moment. I have another systemd automount that *is* via CIFS, and I
lost track of which was which.

system-upgrade from CIFS-mounted repo?

[Greg Woods]

I have a feeling that when this is resolved I'll be doing a face palm and
saying "of course, you idiot!" but I'm not seeing the answer right now.

I have a local repo that I maintain using rsync from an official Fedora
mirror site. This repo is located on one of my "always-on" servers using a
systemd automount in /etc/fstab:

worldsys:/install   /install   nfsrw,x-systemd.automount 0 0

This works great for installing new packages and doing updates, but it does
not work for doing dnf system-upgrade. The packages are not copied when the
"system-upgrade download" is done because they are already on a
locally-available file system, but when  the "system-upgrade reboot" is
done, the upgrade fails (presumably because the remote file system is not
available at the point of the upgrade boot where the upgrade transaction is
run, either  because the network is not up or the automount is not
happening).

Is it impossible to do a system-upgrade from a remote-mounted repo (which
would defeat much of the purpose of maintaining such a repo), or is there a
way to make the network come up and the automount happen at system-upgrade
reboot time?

I suppose I could set up a web server on the system with the repo so that
the download would be forced at system-upgrade download time, but that's a
big hammer for a small nail that I would prefer to avoid.

Thanks,

issues with F30 Live USB stick

[Greg Woods]

I created an F30 Live USB stick, but it won't boot properly. What happens
is that it drops into emergency mode (dracut). Prior to this, journal
messages from dracut-initqueue appear on the screen, the same message
repeating every few seconds for a minute or so, then  it drops into
emergency mode. The repeating message is:

dracut--initqueue timeout -- starting timeout scripts

Then it just says "Warning: could not boot" and drops into emergency mode.

I did verify that my download of
"Fedora-Workstation-Live-x86_64-30-1.2.iso" is good (the calculated
sha256sum matches the checksum from the download site). I created the stick
using "unetbootin" which has always worked for me with previous Fedora
releases. I tried rerunning "unetbootin" to recreate the on-stick OS, but
the result was the same. I tried the stick on a Dell laptop and on a
desktop based on the ASUS Z87 motherboard, same result.

Anybody else seen this? Has anyone successfully created an F30 Live USB
stick?

Thanks,

I'd like to know as well. I have tried KVM periodically, but the
performance is always horrible with Windows VMs, and since having a place
to run all that "windows-only" software is my primary reason for using VMs,
I have always been forced back to VirtualBox.

Re: hibernate stops working after upgrade to F29 from F28

[Greg Woods]

I saw the same thing when upgrading from F27 to F28. "systemctl hibernate"
just prints the "Failed to hibernate system via logind" error, and
"pm-hibernate" (still around from F22 pm-utils) starts the shutdown and
then hangs.

In my case at least, it appears to be a kernel bug. The upgrade also moved
from a 4.18 to a 4.19 kernel, but if I boot the old F27 kernel (4.18), even
with the F28 systemd, then hibernate works again.

interrupted upgrade F28 -> F29 hosed dnf

[Greg Woods]

I was upgrading a system from F28 ro F29 and the power failed during the

When I first brought it back up, there were a lot of dups (f28 and f29
packages both installed). I painstakingly (using rpm) removed all the dups,
so that now "dnf check" runs with no output (other than the locale
complaint). But commands like "update", "check-update", "install" will just
get the traceback. The system seems to be running OK (although still with
an F28 kernel), but of course it is now impossible to update it.

Is there a way to fix this? I'm thinking I could have had a working system
by now by just installing F29 from scratch, but I'm also trying to learn
here. Is a full install my only option at this point?

You can still buy S/390's, but the big money is not in mainframes, but in
supercomputers. It used to be (in the days of Seymour Cray) that a
supercomputer just had a really fast processor that could do vector
processing (running the same instruction on a whole block of memory
locations in parallel in a single clock tick), but we have pretty much
gotten to light speed limitations on how fast a processor can be, so  IBM's
supercomputers these days are clusters of thousands of processors and
cores, exchanging data over specialized high-speed fabrics such as
Infiniband.  Linux is critical to making this work (as well as specialized
application libraries to support interprocess communication on such as
system). The IBM supercomputers I have seen all use a variant of Red Hat
Linux, so I wouldn't be surprised if acquiring Linux developers might not
be the main reason for IBM to want to buy Red Hat.

Yes, it doesn't surprise me to hear that. But I did think of going into the
EFI boot screens and selecting the Fedora partition, and it still wouldn't
load GRUB. Since I can't go back to what it looked like then, it remains
unclear as to exactly what happened.

True. In this case the laptop came with Windows 10 already installed, so I
did something I have done many times before, which was to use gparted to
shrink down the Windows partition to make room for Linux, then installed
Fedora on the remaining space. The error I made on this machine was to not
specify that /boot/efi should mount on the existing Windows EFI partition,
instead allowing the installer to create a new one. All looked good; when I
booted, I got the GRUB screen that included Windows as a selection, and I
was able to boot Fedora just fine at that point. The problem came after the
first time I booted Windows 10 after installing Fedora; from that point on,
GRUB no longer was shown, it just went straight into the Windows boot
manager. Even selecting the Fedora partition from the EFI boot screen would
fail to load GRUB. The system was hosed for anything but Windows. My guess
is, I could have booted from a live USB stick, copied the
/boot/efi/EFI/fedora directory to the same location on the Windows EFI
partition, and run grub-install with the correct incantation to re-create
the GRUB image, and I could have gotten it to work without having to use
the nuclear option of reinstalling Fedora.

The point, of course, was just to show that you can hose yourself trying to
run with multiple EFI partitions. That doesn't mean it can't be done, but
you really have to know what you are doing, and I didn't.

It is possible to get yourself in trouble if you have more than one EFI
partition. My two were on the same drive; I don't know if that makes a
difference. But what happened to me was, after the first time I booted
Windows 10 after installing Fedora, I could no longer boot Linux, it just
went straight to the Windows boot manager without ever showing the GRUB
screen. It was a royal pain. I have since learned more about how EFI boot
works so that I might now be able to recover from this situation, but at
the time, it required a complete reinstall of Fedora to get around the
issue.

Re: Fedora 28 Upgrade Still Boots Fedora 27 Kernel

I have been burned by this before: check in /etc/dnf/dnf.conf to make sure
you are not excluding kernel packages from being updated. That exclusion

Unfortunately, "disable" only removes the service from the

starting it. To be SURE a service cannot be started, mask it.

Windows boot trashes grub

[Greg Woods]

I have two identical Dell Latitude E7470 laptops. On each of them, when I
got them I booted a Fedora Live USB stick, installed gparted, and used it
to shrink down the Windows 10 partition to make room for Fedora. I have
done this process on a lot of laptops going back a lot of years, and this
is the first time I have seen this problem.

On one of the laptops, as soon as I boot into Windows 10, I can no longer
boot Linux. GRUB is somehow trashed and the only way to boot the system is
to select "Windows Boot Manager" in the BIOS, which successfully boots
Windows 10. The other laptop does not have this problem; I can boot
Windows, then get the usual GRUB menu at the next boot and select either
Windows or Fedora, and all is good.

Has anyone ever seen this kind of problem before? Is there a way to recover
GRUB? Last time this happened, I ended up having to completely reinstall
Fedora to get the system back to dual boot. It has now happened again and I
would like to avoid having to reinstall to recover. I would, of course,
also like to prevent this from happening in the first place.

The systems are both using EFI boot, without secureboot.

Thanks for any insights,

This isn't any help for the OP who specified that he didn't want an inkjet

well for printing, scanning  and faxing with the stock hplip driver.  I

This may or may not be related to the OP's issue, but for some reason, the
simple-mtpfs package is not installed by default on Fedora. Without this,
MTP doesn't work. With simple-mtpfs installed, I can use file browsers such
as Nautilus to see the files on my relatively new (Galaxy S6) Android
phone. On my ancient Amazon Kindle Fire HDX tablet, I have never been able
to make file browsing work, but I have been able to copy books on and off
the device using Calibre.

Thanks for that. I probably should have guessed some of that myself,
especially the part about needing exclusive access to all of the storage to
prevent data corruption, given my own experiences with high availability
clusters. I had always secretly believed MTP was invented and promoted by
Microsoft to make it hard to access Android devices from Linux :-)  Nice to
see that's not really the case.

But it still begs the question of why I have so much trouble accessing my
Android device files from my Fedora boxes (all running F26). What packages
are needed for this to work? I already have libmtp installed,  but I have
one desktop that I still cannot access my Galaxy S6 phone from. I plug in
the phone, I get the prompt where I click "Allow" to allow the computer to
have access, but nothing ever happens on the Desktop side. (I am running
standard GNOME on the desktop, I have tried it with both Wayland and Xorg,
not that this should matter).

I noticed a package called jmtpfs that looked promising. I installed this
on my Dell laptop, and now it works from there. However, installing jmtpfs
on the problem desktop did not help.

Do others have as much trouble as I do accessing their Android phones from
a Fedora desktop?

I'll bet this is because the system-upgrade reboot does not start apache. I
have a similar setup except that I use a "file:" designation for my local
repo rather than relying on a web server. This seems to work, and in fact I
have local rsync'ed copies of the entire fedora and fedora-updates repos on
a local machine, and I never have any trouble upgrading it that is due to
having local repos (getting asterisk/dahdi to work after an upgrade is
another thing entirely, but unrelated to local repos, more related to the
fact that the dahdi driver is not free software by Fedora's criteria and
therefore not included in the Fedora repos).

More accurately, the network-online.target doesn't mean what a reasonable
person would think it means. It actually means that the base network
drivers have been loaded, not that all the network interfaces are properly
configured. For most of us, this is useless.

If you are using NetworkManager (default for Fedora), then you can use the
NetworkManager-wait-online service instead, e.g.

After=NetworkManager-wait-online.service

This has always worked for me.

Less kludgy than using a sleep, but obviously it only works if you are
running NetworkManager and this service is enabled.

Just to close out this thread in case someone encounters it in the archives
later: I was able to find some patch files inside the source RPM at

 https://messinet.com/pub/fedora/linux/updates/26/SRPMS/

This also contains the 2.11 version of the dahdi-linux module. After
refreshing my memory on how to use the patch program, I was able to apply
the patches and build the module for the latest F24 kernel
(4.11.12-100.fc24.x86_64) and it is working. Hopefully I can now proceed to
upgrade the asterisk server box to F25 and then F26, and build the dahdi
module for those kernels.

I suppose so, but "upstream" in this case is a hardware vendor, who is much
less motivated to keep supporting a 10-year-old card than they are to sell
new hardware. The last update to the module source was around March of
2016. Unfortunately telephony cards in general are way overpriced for what
they do. Maybe patents involved? But this was a $600 PCI card ten years
ago, I can't afford to just junk it now. If it weren't so expensive to
replace, I wouldn't even think of trying to keep running hardware this old.

I guess I can file a support ticket with Digium, but I doubt I'll get much
of a helpful response.  I was just sort of hoping against hope that
somebody had seen this and knew of a workaround.

In the meantime my only real option is to keep running the old kernel.

A Fedora-related question is wondering whether I can upgrade to F25 and
still keep running an F24 kernel.

compiling dahdi-linux kernel module

[Greg Woods]

The dahdi kernel module (used by asterisk for some Digium telephony cards,
including the one I have) is not included in Fedora because it is not free
software. The dahdi configuration tools are included, but not the kernel
module. The software is free as in beer, it can be downloaded and built,
and I have successfully done that in the past. However, the last time the
kernel module compiled successfully was back
at kernel-4.6.3-300.fc24.x86_64 . On all newer kernels that I have tried, I
get this:

It looks like some warnings are being treated as errors, such as an

non-updateable kernel until I can find a way around this. In my early

Re: wrong disk size

[Greg Woods]

I have heard that there are flash drives on the market that report much
higher capacity than they really have. You can build a file system on them
and it all looks good; "df" and friends show the claimed capacity. But as
soon as you put enough data on the drive to exceed the real capacity, your
data is corrupted (and quite possibly your partition table too). It sounds
like you may have been the victim of one of these scams:

http://www.ebay.com/gds/All-About-Fake-Flash-Drives-2013-/1000177553258/g.html?afsrc=1=true

This article is old. Most of the fake drives out there now are 500GB or
1TB.

Google for "fake 500gb usb flash drive" and you will get lots of hits.

Yeah, pretty much all of this is totally automated these days. There are
programs out there that just probe the entire IP address space looking for
exposed ssh servers, and when one is found, a list of account name/password
combinations is tried. They are looking for *very* low-hanging fruit. If
any login attempt actually succeeds, it is reported for further
investigation.

If you have an exposed ssh server, you will see this kind of
doorknob-rattling. I get around it in one of four ways: 1) Turn off sshd if
I don't really need it on a given system; 2) Use firewall rules to allow
access only from certain known remote locations (so I can get into my home
system from my desktop at work, for instance); 3) run sshd on a
non-standard port (won't stop the serious bad guys, but is usually good
enough to stop the automated doorknob-rattlers); and 4) If you really have
to have an ssh server that allows access from unknown remote locations, run
something like fail2ban that at least automatically blocks them if they try
too often from the same place. And the most important thing is, any of
these defenses can fail if you make a mistake configuring them (won't
happen because we're all perfect, right? :-) , so the most important thing
you can do is use strong passwords so that the brute force guessing cannot
succeed.

I can think of two ways:

1) Check the logs of your DHCP server to see what IP's it has handed out.
If you don't have too many machines on your net, you can try them all until
you find the right one

2) Run a scan to find what IP's on your network are listening on the
printer port. Something like:

# nmap -sT -p631 your-ip-space

(Who is listening on TCP port 631)

Your IP space is what subnet you expect to find the printer on, like it
might be 192.168.1.0/24
