Did something just change with HDMI support?
by Tom Horsley
I use my samsung TV (QN90B) as a monitor. Until today, when I turned
it on, the picture would come right up and I could use it immediately.
Now, for some reason, a big banner appears at the top of the screen
telling me it is connected to HDMI 4 and saying what resolution it
is displaying (and the time of day). Is some fancy new power management
turning off the HDMI port when it detects the monitor was powered
down, then turning it back on and inducing the TV to report this info?
It is very irritating.
(I'm using the nvidia drivers from rpmfusion.)

Pipewire - Sample Format Conversions
by Jorge Fábregas
Hi,
I recently tweaked my pipewire.conf to allow various sample rates for my
AudioEngine D1 DAC:
default.clock.allowed-rates = [ 96000 88200 48000 44100 32000 ]
...and it's working smoothly. Now, I'm curious about bit depth.
My DAC supports S24_3LE and S16_LE formats, but Pipewire seems to
default to S24_3LE even for 16-bit files from CDs. Is there a parameter
akin to the above "allowed rates" but for "sample formats" that I can
use to dynamically adjust bit depth?
Any insights or tips would be much appreciated.
Thanks,
Jorge
P.S.: I'm aware I might not hear a difference; I'm optimizing to avoid
runtime conversions :)

After F35->F38 install, video player, firefox not behaving well
by Michael Hennebry
As noted in another thread, I recently installed F38,
retaining my /home partition.
When I try to play a .avi file,
Videos claims "Could not initialise OpenGL support".
dnf was not a help.
How do I get videos to work?
Firefox is also unpleasantly interesting.
Firefox was and is set to restore on startup.
There were a lot of pages to restore.
They all came up with a single blank tab.
Do I need to start from scratch?

Listing a libvirt domain
by Patrick O'Callaghan
I haven't used QEMU/KVM in a long time, and want to back up an existing
VM to external storage. I can see the domain using virt-manager, but
when I try to examine it using virt-ls (or other virt-* commands) I'm
getting an error that the domain doesn't exist.
In fact, 'virt-ls --all' lists no domains, even the one I'm looking at
in virt-manager.
Any ideas?

Sound synthesizer for Linux
by Fulko Hew
About 15 years or so ago, I was using a sound synthesizer on Fedora
that was GUI drag-n-drop sound modules, and draw wires between them
There were VCOs, filters, ADSR, mixers, etc.
It looks like I never wrote down what I installed back then.
Can anyone remember or think of what that software was called?
Nothing I've been able to Google now resembles that simple/powerful tool.
TIA

iPad file backup?
by ToddAndMargo
Hi All,
Fedora 38
My wife has her eye on a new iPad to replace her outgoing
Android tablet. (I can't find any Fedora tablets.)
Is there a way to backup her working files from an iPad to
Fedora as I can do with her Android?
Many thanks,
-T

docker and iptables
by Alex
Hi,
I'm using docker on fedora38 and can't figure out how to prevent port 8080
from being available to the outside world. I've done quite a bit of reading
on this, and it appears I'm not the only one having trouble figuring this
out. This docker doc appears to indicate it shouldn't be listening on the
external port when the -p option is not used.
https://docs.docker.com/network/#the-world
Here's the output from the commands related to docker:
$ ps ax|grep docker
748 ? Ssl 0:01 /usr/bin/dockerd --host=fd:// --exec-opt

-address /var/run/docker/containerd/containerd.sock
I've tried creating an explicit rule that restricts access to port 8080 on
all interfaces except for localhost, but scanning that port externally
still shows it's available.
Chain DOCKER-USER (1 references)

F38: systemd-resolved.service oddity
by Ranjan Maitra
Dear friends,
From the past week, I have had an issue in that after several hours, some particular sites become inaccessible to me, and can only be accessed if I use restart using sudo systemctl restart systemd-resolved.service
What particular issues cause this? Why did it start a week ago, and has become quite reliable in its annoyance? (I have to say that when I can no longer access this site, I am no longer on Cisco SecureClient VPN, which is also one of the sites which can not be accessed with Cisco SecureClient VPN without restarting systemd-resolved.service, and the site is my worksite domain).
Happy to file bug reports, and to test different things. I am on a fully updated F38.
Many thanks and best wishes,
Ranjan

how to remove rhgb quiet from grub & make it permanent
by olivares33561
Dear kind fedora users,
I will like to remove rhgb quiet from grub. I have checked out some literature[1] and want to make sure not to mess up my system. I have a little problem, when loading system sometimes I don't get a desktop and have "No display" on screen. I have to manually poweroff system and restart it. When I restart I edit the grub loading and remove the "rhgb quiet" part so I can see what is going on. At the end a prompt says something in journal was bad and was deleted and I can login safely. This has happened several times on kernels 6.5.* series.
I hope I can get a permanent removal of these so I do not have to edit the line and press F10 to boot it. I want to see what is happening and preventing X/Wayland to load up correctly. Running F38 if it is relevant.
Best Regards,
Antonio

EarlyOOM and hibernation resume
by Patrick O'Callaghan
This is weird.
If I hibernate my system manually by calling 'systemctl hibernate', I
can resume without problems even if I leave everything powered down for
90 minutes.
If I do it via a crontab call it fails even when the hibernation time
is under an hour (also when it's several hours).
"Failure" consists of the system being alive, but with nothing on the
screen. I can switch to a text console and verify that my previously
running session is not running, that graphical.target IS running
(loaded and active), and that the display manager (SDDM or GDM), plus
Plasma, plus Kwin, are all listed by 'pgrep -fl ' as 'earlyoom'.
I have ample swap (48GB plus zram for a 16GB RAM setup) and have never
seen the EarlyOOM situation while actively using the system.
I've no idea what's going on here or how to diagnose it.
