It doesn't.  That's the system preset.  "enable" only changes the

I'm not sure what's going on here.  systemd kind of starts it, but then 
apparently either systemd shuts it down or the service decides it has 
nothing to do and quits.


Try running just "journalctl -b" and see if there are any other relevant

You can't change the preset, other than editing some files that you

Re: Which scanner/copier do you use with Fedora?

I keep reading good things said about Brother scanners/all-in-ones. 
Reading into details, it's always one of two things. It also involves a

buy it, and hope that it works.


I've been following this discussion because I currently have an HP-4650 
3 in 1 inkjet and I'd like to replace it with a laser 3 in 1.  I've been 
looking at the Brother DCP-L2640DW.  Right now it goes for $200.  I've 
been looking to see if it works with Fedora but have not been having 
much luck other than reviews on Amazon.  Some say it works out of the 
box on Linux and other say they had to download the driver.  I believe 
it's rather new, being released last summer so I imagine it should work 
as both a printer with cups and scanner with xsane.


Does anyone have any experience with this printer/scanner/copier?

It is common to see manufacturers of low-end tablets and pc's buying
cpu's from Intel that only have SSE2-SSE4.1+AES+RDRAND enabled. I
encounter them regularly in low-end netbooks. The cpu's probably have
higher ISAs, they just are not enabled.

Intel will also de-clock or slow down the cpu for the price point. I
was talking to David Johnson, who designed Intel's RDRAND circuit. He
told me intel can tune about 100 different parameters to vary cpu
features and speeds for a particular price point.

One comment about Brother... My mother uses Linux Mint and has a
Brother MFC-J870DW All-in-One over USB. My complaint about the
MFC-J870DW is, it only supplies a 32-bit driver. So we have to run the
i386 multiarch gear on her 64-bit machine.

The MFC-J870DW is the only thing stopping me from:

sudo apt-get purge $(dpkg --get-selections | grep ":i386" | awk
'{print $1}')
sudo dpkg --remove-architecture i386

In the past we tried to set up the MFC-J870DW without the Brother
driver. It never worked that way, so we had to install the driver. I
suspect the problems had to do with the All-in-One connected directly
to the machine via USB.

and ran into issues where Fedora workstation would not install on 
raid only Fedora server had support for doing that.


I don't know why there would be a difference.  The installer and 
drivers are the same in both cases.  I've never used the server 
install and I've been using software raid for a long time.
Sorry, I was referring to physical raid from a motherboard that 
provided built in Raid 10 support. At the time I was doing this it 
was documented that Fedora workstation did support installing on Raid 
but Fedora Server did. I was just playing around with the environment 
and one issue I had was you had to install drivers into the installer 
for it to see the raid partition, and the motherboard only built 
drivers for windows, so I finished up installing the boot partition 
for Fedora on a non-raid devices and the rest of the partitions on raid.


That's why I mentioned that the drivers are the same in both cases.  I 
don't know why Workstation wouldn't be able to do it. But also, the OP 
specifically mentioned that he was using software raid anyway.

Sorry, I missed that bit.

The message is about AVX2, not AVX.  The computer I'm currently using

not any of the higher ones.


You can look in /proc/cpuinfo to see the flags, or install "cpuid" to 
get very detailed information.
Thanks Samuel. I don't actually need that level of support, I was just 
curious. Until I got the message I hadn't thought about anything related 
to AVX. The only reason I got the message was I'm following lessons in a 
Python book to refresh my python knowledge for future use at work, and 
the book was using pygame as an example of how to import modules. I'm 
running an AMD Ryzen 9 5950X 16-Core which I installed 18 months or so ago.

I believe that the policies and practices described here are for HP's

Their reputation definitely precedes them.

HP's laser printers had a little bit bit rep. I've had much better

The one I'm currently wrangling with is a laser.


I keep reading good things said about Brother scanners/all-in-ones. 
Reading into details, it's always one of two things. It also involves 
a driver download, like hplip's modus operandi, and it's not really an 
out of the box solution. Alternatively, the alleged printer model is 
nowhere to be found in xsane's hardware database. So, it's basically 
pot luck: buy it, and hope that it works.


Anyway, I think I managed to get this HP to work over Ethernet. With a 
direct USB connection xsane is still erroring out. But Ethernet seems 
to be working.



But now they have. Take a look at:

https://www.wired.com/story/hp-all-in-plan-printer-subscription-service/


Yes, and looks like they're starting to push this onto the laser 
printers too, as I see from the packaging and the marketing material 
on this laser.
I have an Epson ET3700 All_in_one printer/scanner connected as a network 
device on my router via ethernet (it supports wifi but where it is 
situated it can see a wifi signal. I'm also using the 80211AX protocol 
on my router). Epson have a driver for the printer but I don't use it, I 
use the headerless driver from cups. I use simple document scanner for 
scanning and looking at the KDE Throbber I don't appear to have either 
Sane or Xsane installed on F39. The one issue I do have with Simple 
Scanner is on start up it doesn't see the scanner, I have to refresh its 
detection for it to see the device.

Steve

As I already pointed out, my Brother unit did not require a driver
download. One is available, but I don't use it.

As I haven't tested every model of Brother all-in-one I can't guarantee
that they all work, but I'd be surprised is they didn't. This is the
way all such devices will be expected to work in the near future.

It doesn't.  That's the system preset.  "enable" only changes the first

You can use "journalctl -b -u libvirtd" to find out what has happened.

In virt-manager, if you select the Edit menu and then "Connection

Did this add libvirtd to the multi user target?
If so it will start when you boot fedora.

Is that what you mean by preset?

Re: Which scanner/copier do you use with Fedora?

2024-03-21 Thread Dave Ihnat
I've been following this, but as I'm not currently using my scanner with
Fedora, I didn't pipe up. I, personally, am thoroughly satisfied with
Fujitsu scanners. My current one is a venerable SP-1425. Not cheap, but "do
one thing and do it well" certainly applies.

But with the talk of using HP AiOs, I had to pipe up. I have advised all my
clients to no longer buy HP printers of any type, including the AiOs, and
will personally never buy another HP printer until and unless they back off
their current policies and practices.

This first bit me at a client who purchased an HP AiO last year. It
insisted on tying itself to an HP account. I managed to get it to work
without doing so--and in a week, it stopped printing. Support insisted it
had to be connected to HP, and the client told me to do so. After it
connected, it updated the firmware without warning or requesting
permission--and immediately stopped printing because the toner in use was a
from a third-party vendor. They scrapped the printer and got a Brother.
(Note this was before HP actually admitted to what they were doing.)

But now they have. Take a look at:

No, I didn't check. I had an earlier Brother unit for years before it
finally gave up the ghost and I got an updated one (didn't even notice
it does double-sided printing until it worked :-). Any modern scanner
should support DNS-SD via Avahi on Linux. Even more so because
Microsoft has announced that they will no longer ship manufacturer
device drivers for printers and scanners, so the market is being pushed
into standardising. I don't know if some special use-cases might
require a device-specific driver, but I don't personally care.

As regards toner compatibility, Amazon has a number of brands that
work. I tend to get special offers of 2 at a time.

Not all recent CPUs have AVX, only some CPUs I believe.
Therefore the preference for detect at runtime.

Did you get that unit after crossing your fingers, and hoping that it works,  
or did you verify compatibility somehow. I tried reconciling what's on the  
market now versus xsane's hardware compatibility list without much luck.


I ended up ordering an HP all in one, MFP 232, because hplip's hardware  
compatibility list claimed that model is fully supported, including scanning.


So it arrived. I used hplip to set it up, printing works fine. Pushing the  
"scan" button in hplip guided me through downloading the driver, then it  
launched xsane.


xsane sees the scanner. But the preview button hangs, then eventually comes  
back with a "Faied to star scanner: error during device I/O".


Based on my Google searches:

# scanimage -L

It's not showing up in airscan-discover.

I have it connected via ethernet, I'm suspecting that scanning only works  
via a direct connection. Digging further…

Right, but you can also define the failover as a systemd service. systemd will
do the locking itself since "systemctl start X" is a noop if X is started.

In addition, you get the control with systemctl and the log in the journal.

For example:

-- X.service --

[Unit]
Description=%n

[Service]
Type=oneshot
SyslogIdentifier=%N
RemainAfterExit=yes

ExecStart=command doing the failover

-- X.service --

Contribute to Podman 5 Test Week 2024-03-21 through 2024-03-27

2024-03-21 Thread Sumantro Mukherjee
Hey Folks!

Fedora 40 is going to ship with Podman 5[0] and as part of this changeset,
there will be a lot of breaking changes which can affect your
container workflow.
To ensure a smooth transition, the Podman team and the Quality team of
Fedora have
decided to host a test week[1].

The idea is for users to test Podman 5 on a Fedora 40 Pre-release machine
and submit results in the Test Day App[2]. If you have spare cycles or use
Podman as a daily driver, it will be
great to have some folks try out and report bugs right away.
