DRPM performance ?
by jim.cromie＠gmail.com
so a couple of weeks ago,
I did a dnf update, and got ~ 19% reduction due to DRPM
that was by far the highest return on the effort Id seen.
previous experience for me was 1-4%.
I should have grabbed a "screenshot" and sent it here.
Whats the "average" experience here ?
are there statistics ?
do *noarch 's do better ?
how often do you see some version of "find/download failed" ?
(it sometimes appears to be a cached-version problem,
particularly if the update is older than a few days)

audio problem
by Eyal Lebedinsky
I am on f34 5.15.16-100.fc34.x86_64
This problem started recently (a few weeks, maybe a little longer?).
Initially I noticed audio hiccups when playing mythtv recordings. At times there was also video noise
but not always.
I then found that playing audio from a network stream (with vlc) also had hiccups. The sound would
stop and start, sometime even repeat a fraction of a second.
I now played a track from a local disk and the same issues were heard.
There are no messages to indicate a problem. I then used 'mplayer' which has more console messages
and I now can see an issue:

I get similar problems with [HDMI 3] and with [ALC887-VD Analog] selected using pavucontrol.
lspci shows
Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10)
What can I do now to diagnose the problem?
One more data point: for a long time (many months) I had a problem where the system locks up hard
needing a cold restart. There were no hiccups otherwise. It always had mythtv playing or YouTube.
When locked the sound of the last second would loop continuously until the reset. The video is frozen then.
Maybe related? This is a long running problem (happens once every few months) but the audio stutter
is a recent, new issue.
TIA

Kernel 5.16.18 refuses to process sound
by Temlakos
Everyone:
Today I recorded a video using Open Broadcast Studio (OBS) and a
Logitech BRIO camera with build-in microphone that has delivered
flawless performance to date.
Imagine my shock and chagrin when I played a video I had just recorded,
only to find that I had picture, but no sound.
I just fell back on Kernel 5.16.17, and it picked up the sound just
fine. Last Known Good and all that.
All that to say this: the kernel has a bug, and killed the handling of
sound from microphones. At least in the current version. The last
version handled it without a hitch and still does.
I have removed that version of the kernel and would like to skip it. Two
questions:
1. How do I set DNFDragora to skip a current version and call me back
when it has a new version of the kernel for me to try out?
2. How do I file a bug against the kernel? I tried accessing a bug
reporting program but don't know where to find it.

upower forgets UPS when nut-server starts
by Dave Ulrick
I'm running Fedora 34 on three Linux systems that are connected to USB
UPSes. I have installed NUT (Network UPS Tools) on all three.
If I connect with nut-server stopped, upower detects the UPS:
# upower -d

Then, if I start 'nut-server' (systemctl start nut-server), the UPS
disappears from upower.

The visible effect of this issue is that the XFCE4 Power Manager applet
doesn't show the status of the UPS.
Once upower has forgotten the UPS, I can make it remember it by running:
# systemctl stop nut-server
# systemctl restart upower
but it will forget it again if I run:
# systemctl start nut-server
Is this a feature or a bug?
Thanks,
Dave

wifi connection problem.
by François Patte
Bonjour,
Every day, after sometimes, my wifi connection is lost with this message
in the logs:
wpa_supplicant[3076]: wlp6s0: CTRL-EVENT-BEACON-LOSS
I don't know what causes this. It happens since the last upgrade I
performed on my machine.
To reconnect my wifi, I have to restart the NetworkManager service.
Is it a known bug and what causes this dysfonction?
Thank you.

Have one of 5 machines that no longer autoboots??
by Michael D. Setzer II
Have 5 Fedora Linux machines at home. 3 with Fedora 34
and 2 with Fedora 35.
One of the Fedora 34 machines after kernel upgrade two
times ago has stopped auto booting?? Comes up with
grub menu and sits there doing nothing?
Pressing the Enter key has it boot the highlighted top
latest kernel, and it then works fine.
Looked at log files, but didn't see anything.
Did a reinstall of the kernel-core no change.
Did a reinstall of grub2 files and again no change.
Looked at /etc/defaults/grub seems same as other
machines.
Saw some lines about hibernation in boot.log, but never
have used hibernation.
This machine is generally headless (no monitor).
Have a monitor hooked at moment, but anytime I do a
reboot on it, have to manually hit the enter key.
Today dnf update included another kernel, but same
thing. New kernel shows at top, but no timeout, and only
manually pressing enter gets it to boot.
Any ideals? Was planning on upgrading machine to 35,
but with boot process acting up don't know.
Thanks.

How to retrieveve user's credential from IPA database?
by Roger Seguin
We have a GUI-based computer program that drives an external device/machine.
By default our software only displays limited information on that external device.
However, when a power user (group defined in /etc) identifies himself by entering their credentials through our software GUI, our software then checks those credentials against /etc/shadow using crypt() and getspnam() and, if succesful, provides extra functions for configuring our external device/machine.
Actually, our software runs on several networked computers and our users, which are all local (defined in /etc), are duplicated on each computer.
This is not ideal and we would rather like to have all users managed by IPA in a central place (dedicated computer as the IPA server) with our software running in IPA clients. Therefore, our software won't be able to check users' credentials using the local /etc/shadow file anymore.
Basically, we would need to be able to query IPA programmatically (C language - or at least a shell script) to check that a username+password is correct.
How can we process?
Thanks

Very Weird Video Problem: SOLVED
by Richard Kimberly Heck
I'm posting this just because it was so weird, in the hopes that maybe
it helps someone somewhere down the road.
Earlier today, videos embedded in web pages just stopped playing on my
laptop. E.g., if I go to YouTube and click on any video at all, it won't
start. Or, better, the ad won't. It just kind of sits there with this
spinning thingy and in some cases pops up a dialog saying "If playback
doesn't begin shortly, try restarting your device".
Same problem with Chrome, Firefox, and Konqueror. Same problem in both
KDE and XFCE. Same problem even with a new user. Some kind of system
problem, apparently.
The web suggested disabling hardware accelaration in Chrome, but that
didn't help. It turned out that the problem was a mis-configured audio
device. I'd somehow managed to put the internal audio card into "Analog
Output Stereo" instead of "Analog Output Duplex". Setting it back
unblocked the device somehow and allowed the videos to play. Why that
didn't affect videos playing in VLC, say, I don't know.
Thanks to

for the clue.
