You can set a description for the printer that it will broadcast in the 
mdns advertisement packets.  CUPS will show that when you go to print.

 memtest86+ I've never tried on UEFI. For UEFI I use memtest86, and in
/boot/grub2/custom.cfg to run it I have this head:

menuentry "memtest86 8.3 EFI" {
search --no-floppy --label --set=root PNY5P01ESP
chainloader /mt83x64.efi
}

/boot/grub2/custom.cfg is utilized as a consequence of my customization of
/etc/grub.d/, which quite simply moves the content of 40_custom to 06_custom,
leaving 40_custom empty.

/boot/grub2/custom.cfg contains all the boot stanzas I routinely use on UEFI, as
grub2-mkconfig places all custom.cfg stanzas ahead of its own auto-generated 
ones
in grub.cfg as a consequence of 06_custom content.

IOW, NAICT, 40_custom in grub2-efi works no differently with UEFI than in grub2
legacy booting.

Is there an equivalent to 40_custom with EFI boot?

2022-12-09 Thread Michael D. Setzer II via users
Wondering if possible to add non-Fedora options to EFI boot menu with some 
method similar to the 40_Custom. Thanks.

I've maintained a project on Sourceforge going back to 2004, and it was 
originally a cd only boot option, but over years create usb and ability to boot 
directly from grub2 menu using 40_custom. 
Few years ago, created EFI boot options that work with cd and usb using 
grub4dos and grub4dosefi as boot loaders. Have looked for a process similar to 
40_custom for EFI, but have not located anything.

The 40_custom is very simple.
# !/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
menuentry G4L_Version_0.62_video_800x600 {
set gfxpayload=800x600x16,800x600
linux /bz6x0.12 root=/dev/ram0 telnetd=yes
initrd /ramdisk.lzma
}

Has the kernal file and ramdisk.lzma in the /boot directory and loads program 
directly from grub2 boot menu.

With grub4dos regular boot the menu has this for booting.

title G4L - bz6x0.12 - with vga=788
find --set-root /linux/bz6x0.12
kernel /linux/bz6x0.12 root=/dev/ram0 vga=788 telnetd=yes
initrd /linux/ramdisk.lzma

Also have this to run memtest since regular Fedora one doesn't seem to work??
title memtest
find --set-root /memtest86+-5.31b.iso
#Uses memdisk from syslinux 6.04pre1
kernel /memdisk iso
initrd /memtest86+-5.31b.iso

In the EFI/grub/menu.list have to boot. memtest doesn't work with the EFI boot 
so no option for that.

title G4L - bz6x0.12 - Version 0.62 Default Screen Resolution
find --set-root /linux/bz6x0.12
kernel /linux/bz6x0.12 root=/dev/ram0 telnetd=yes

Capsule summary: a resolver returns either: "found", "not found", or "don't

mdns is supposed to resolve .local domains. Therefore this resolver would  
return "don't know" for regular domain names, but if it's a lookup  
for .local and it can't resolve it you'll get "not found".


The general idea is that if a .local lookup fails don't even bother doing  
DNS queries for that. Which does that makes. Now, why this would be broken,  
that's a different story.

I don't remember which fedora that abort nonsense first showed up
in but none of my systems ever worked properly unless I removed it.
I always wondered how it got to be the default when no name lookup
ever worked on any system that was configured that way. You'd think
someone would notice.

The /etc/nsswitch.conf file sets, amongst other things, how names will
be resolved.  With that shortened version it looks to see if you have
written the address into the /etc/hosts file, and then does a DNS query
if the hosts file doesn't provide an answer.

Previously, yours was:

hosts:  files mdns4_minimal [NOTFOUND=return] dns myhostname

Which first tries the hosts file, then mdns, then aborts if nothing
found (I believe, going by the comments in the rest of the file).  The
list of things in that line is illogical, to me.  Why would have have
two more things listed after an abort?  (Doing a DNS query, and I'm not
sure what the last one, "myhostname" does.)

If you do use mdns on your LAN, try putting it back in but without the
[NOTFOUND=return] parameter, and see what good that does you.

mdns is that avahi/zeroconf/autoconf that resolves the local machine
names that they self-identify as, with a .local top level domain.

e.g.  This PC's hostname is "rocky", it can announce itself as
"rocky.local", and other machines on my LAN will/may find it.

It's adhoc, and very much self-mismanaging, in my opinion.  Though it
is used for automatic discover of things like printers, media players,
network storage devices, etc, which could be useful.  But how does it
handle you having two identical models of printer on a LAN?  How would
you know which one was upstairs or downstairs, for instance, if they
all just automatically named themselves without your intervention?

Are you supposed to remember which epson printer is which without any
clues?  Are they both going to get the same name?  Will they self-
modify one of their names?  Will they always be the same ones in the
same order?  I despise things that make me play guessing games.

Hmm, okay then that must be dig directly querying the external servers
and other things doing something with your system in the middle.  Still
a useful test, shows that name resolution *can* work.

It seems to me that having an abort function in the middle of the list
of things to check, rather than at the end, might be a cause of grief. 
I've never understood why some are configured that way.  You could try
modifying that line.

On my ye olde CentOS 7 and Fedora 36, mine just has 

hosts: files dns

(I don't make use of mdns/zeroconf/automangle)

The "files" option means to check the /etc/hosts file, which is
typically just used for the localhost addresses, now.

[tim@rocky ~]$ cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

Same as me, so DNS queries are being answered correctly, by the Google
DNS servers:

You could see if doing "dig slashdot.org @8.8.8.8" gets the same
results as "dig slashdot.org @8.8.4.4" (they do, here).

It is resolving.  It looks like you're having a web browser issue (not
connecting, or something jamming in the cache).  I'm guessing you've
restarted your browsing during this situation.  But have you tried
flushing its cache, too?  You can flush the cache without destroying
saved logins, history, etc.

Do you use one of those HTTPS-only plug-ins?

Do you get different results for attempting http://slashdot.org/ versus
https://slashdot.org ?

Do you have more than one browser installed on the problem machine?

Can you try installing another one, even if just temporarily?

You are running an OS that hasn’t seen any updates since 2017 (the 5 year 
anniversary for end of support is coming up on the 12th.)   I’m amazed it even 
works with modern web sites. 

There is no point debugging it any further. Upgrade your OS.

Probably try shifting this directory out of the way and see what it does:
~/.config/pulse/

And there may be some pulse runtime files in /tmp that need removing.

Yes.  That would have helped.

What's in your /etc/resolv.conf and /etc/nsswitch.conf files?

Do you have the "dig" tool installed, what results does it return (and
in comparison to your other "working okay" machines)?

Likewise for "nslookup" or "host" command queries for slashdot.org?

Are your other devices using the same DNS server?

What DNS server are you using?  Your ISP's, one running on your PC, one
on the WWW?

My dig query returned these answers:
slashdot.org.   157 IN  A   104.18.29.86
slashdot.org.   157 IN  A   104.18.28.86

And nslookup the same:
[tim@rocky ~]$ nslookup slashdot.org
Server: 127.0.0.1
Address:127.0.0.1#53

Non-authoritative answer:
Name:   slashdot.org
Address: 104.18.28.86
Name:   slashdot.org
Address: 104.18.29.86

Perhaps one of those servers is being used by one of your computers,
and another is using the other, and one is inaccessible to you?

And, yes, slashdot.org does load in my web browser, here.

I think that I started out by stating that I was stuck on 25, but 
planning to upgrade RSN, because I know that Things Have Changed, and 
hoped that people would at least try to give suggestions that wouldn't 
work on my system.  And, if you didn't know that I was still on 25, why 
did your suggestion state that you don't know if it would work on 25?

I tidbit I remember encountering with pipewire:

If you reinstalled, but kept your existing home partition, you may have
systemd "user" services disabled or masked that pipewire requires.

One way to check this is to create a brand new user, login as new
user and see if (with all the default for new user) sound works.
If so, then all you have to do is figure out what the relevant difference
is (good luck :-).

Is it the browser, or whole system, that can't resolve it?

The dig or nslookup commands will be using the OS to resolve the
addresses.

A web browser can internally cache results, and will sometimes get
stuck with cached data that requires you to restart the browser to
purge it.

You could try querying some likely sub-domains to see if you get any
answer (www.slashdot.org, mail.slashdot.org, etc).

I should add my (fresh) install was a MATE-Compiz spin, with no other

pipewire-utils-0.3.61-1.fc36.x86_64


I'm inclined to say if you've got a working system, then don't try
swapping pulseaudio for pipewire, or vice versa.  Stick with a working
system.

I wonder if your prior research showing pipewire needed lots of
configuration was to do with people using it like jack?  So they can
plumb *this* through *that* for special purposes.  I had a brief dabble
with that trying several different audio recording software programs
and gave up for it being hideously complex and ill-explained.

I work in audio-video production, and patching hardware into extremely
complex combinations is something I'm well used to (since the 1990s). 
But I find the computing fraternity's attempts to do similar things
always terribly mangled.  Audio workstations are a nightmare.  Way too
much like the old domestic Tascam 4 channel cassette decks with people
submixing and overdubbing all over the place to cope with its lack of
enough tracks, and its oddball input channels configuration.

So I don't go much past Audacity, and manual editing that's not all
that far removed from 1/4" tape-editing with tape and razor blades.

I've been there, the main problem is there are something like a dozen
different services which may or may not be cacheing DNS information, and
you have to figure out which ones are running and lookup how to make
that one clear its cache, then do the same for all the others.

nscd, systemd-resolved, dnsmasq, bind are just the ones I've run
into before that I can remember, I think there are others as well.

Root login is disabled because the account doesn't have a password.  You 
can give it one during install, but it isn't required, so most people 
never realize that they can do that.  As I prefer su to sudo, I always 
do.  To correct that without reinstalling, run this:


sudo passwd

which will you to change (or in this case set) the root password.  Once 
that's done you, and anybody else who knows it can become root.

By default, the root login is blocked. Therefore, you login as a user and then 
acquire administrative privileges. (Button center at the top) you must use an 
user account with sudo privileges, i.e. member of group wheel.

Cockpit as root

2022-12-09 Thread Emmett Culley via users

I am not able to login to cockpit, localhost:9090, as root.  I can login as a 
normal user, but that isn't acceptable.  Why would I even need cockpit as a 
normal user?

I have a fully updated Fedora instance.  It may be related somehow to plasma as at the 
top of the login dialog I see "Fedora Linux KDE Plasma".

I suppose there is a configuration option to allow root logins. Note that sudo 
is not an option I am interested in using.

Re: Youtube Videos Don't Play in Fedora

2022-12-09 Thread John Pilkington
You have repeated many times that removing pulseaudio would remove 
gnome-shell.


Suggested workarounds have been

 'rpm -e --nodeps pulseaudio' followed by 'dnf install pipewire'

and the perhaps more mainstream

 'dnf swap pipewire pulseaudio  --allowerasing'

Any comment?

the moment where pulse manager keeps crashing. I might try a reinstall
of all pulseaudio packages if I can, and see if that improves things.
I can't uninstall either application as uninstallation of both
applications want to uninstall Gnome Shell which is protected from
uninstalling.

There's that dnf swap command which is supposed to take care of
replacing one package with the other.  It ought to avoid the system
wanting to remove Gnome.

e.g. dnf swap pulseaudio pipewire (or something very much like that).

Considering pulseaudio is being deprecated, maybe you should try seeing
if pipewire works better for you.
I also tried "sudo dnf swap pulseaudio pipewire" and that failed 
because of a number of pulsaudio-module packages causing conflicts, 
which I removed each time the command failed, until it got to a 
conflict on pulseaudio-module-bluetooth which cannot be removed 
because it wants to remove gnome-shell. Pipewire also has an 
equivalent module that wants to remove gnome-shell if it is 
uninstalled, so it looks like both packages have been deliberately 
designed to not be able to be removed because of gnome-shell.

A remove of gnome-shell has been banned from being allowed to happen.

Steve



I have not tried it in this context, and don't know if it carries 
risks, but maybe


sudo rpm -e --nodeps pulseaudio

followed by

sudo dnf install pipewire

would avoid that problem?
I tried that to remove pulseaudio and after reboot both Gnome and KDE 
refused to start.
I did a reinstall of F36 from a live cd and that process installed both 
pulseaudio and pipewire and set up the sound interface to use 
pulseaudio, but youtube videos played without issue.
Given both pulseaudio and pipewire were installed I tried dnf swap 
pulseaudio pipewire and that failed on the grounds that pulseaudio 
couldn't be removed because it would remove gnome-shell.
I then upgraded to F37, but that stuffed my system up (every time I 
tried to anything on the desktop the entire desktop would flash), so I 
had to redo the F36 and F37 installs, fortunately after the second set 
of installs everything was fine and the videos still continued to play 
with audio.

Steve

"mutter" is basically the rendering engine for "gnome-shell" which

is what should be used going forward.
Pipewire doesn't work. It was videos not playing without audio muted 
that started this thread. And from what I've seen on the net there is 
potentially a lot of manual configuration required to get pipewire to 
work, so my view on what I'm seeing is pipewire is not exactly stable.


Clearly pipewire *is* working for the vast majority of people with no 
configuration required.  I didn't even notice the transition. If you 
look online, you are most likely going to find the people that are 
having trouble because all the ones that are working have no reason to 
post.  And often the reason it's not working is because of messing 
with the configs.


I also can't remove pulseaudio because pulseaudio-module-bluetooth 
want to remove Gnome-shell.


Considering that I have gnome-shell installed without that package, 
it's not actually required.  You need to look at the dependency 
messages to see what's causing the problem.
The message was "pulseaudio-module-bluetooth can't be removed because it 
would remove protected package gnome-shell". The equivalent package in 
pipewire had exactly the same issue.


I've just gotten back on after a fresh install, because I tried a 
suggestion in an earlier thread to remove packages by passing 
dependencies and removed pulseaudio and after doing that and rebooting 
both Gnome and KDE refused to start.
I installed F36 from a live cd and it installed both pipewire and 
pulseaudio and configured the system to use pulseaudio, and youtube 
videos play properly with sound.
After installing F36 I tried using dnf swap pulseaudio pipewire, but 
that refused to proceed complaining pulseaudio couldn't be replaced by 
pipewire because that process wanted to uninstall gnome-shell.
I've upgraded to F37 and the youtube videos are still playing properly, 
I haven't verified yet whether pulseaudio is still installed, but I'm 
assuming it is given the gnome-shell issue.
I had to do the F36 and upgrade to F37 twice because the first upgrade 
to F37 destroyed my system. After the first upgrade every time I didn't 
anything on the desktop everything would flash.

It does on my Fedora 36 installation, without me doing anything.  I did
a default fresh install, and this's what it installed, I didn't do any
customisation of audio:  It has pipepire and wireplumber, there's no
pulseaudio.  I haven't tried swapping or having two conflicting things
together.  I'm yet to try Fedora 37.  I do have an issue where the
volume control applet (MATE) keeps crashing, but it reloads and audio
is still playing before, during, and after.  The crashing is a recent
thing, in the last few weeks.  I hadn't had it before then.

So I'm inclined to say it does "work," but there's some aspect of it
that's a problem with your system.  Possibly because you did an upgrade
install you've inherited a conflict.  I stopped doing them years ago
because of that kind of thing (amongst other upgrade problems - like it
taking an age to work out what packages to install, me spending ages
managing choice conflicts, very slow installs, lots of config
debugging, etc).

I've noted throughout your thread that you also have problems with
pulseaudio, and getting youtube videos to even start playing (here,
they'll play even without any audio hardware enabled).  So, it sounds
like you have quite a few conflicts.

Do you have a spare hard drive that you can try a fresh install to,
with your usual drive unplugged?  Or can you try running a live disc?
