Update to F35, no audio!
by Neal Becker
Just updated F34->F35 and now I have no audio. Tried under kde and
then gnome. Seems there are no audio devices. F34 was working with
pipewire.
How can I troubleshoot?
Thanks,
Neal

Debugging USB device issues
by Philip Rhoades
People,
I didn't get a response to my previous Q re an apparent problem with
getting gphoto2 to work with my GoPro Hero 4 Session camera - I hadn't
used the camera for a while and I thought maybe the Fedora upgrades
since then were the cause of the problem - but maybe the problem is
actually with the USB port on the camera? (gphoto2 used to work). The
camera actually charges OK through the port and I can record videos and
then move them to Fedora by moving the SC card to a card reader,
mounting the dir and copying video files to the HD so the camera itself
and device charging seems to be OK.
I am getting nothing recorded in /var/log/messages when I plug in the
GoPro and push its power button (plugging in any other USB device is
working of course) so maybe it is the USB port on the camera that is the
problem? - is there any way to debug that from the Fedora workstation?
Thanks,
Phil.

partially invisible back-up DVD.
by home user
(fedora-34; gnome)
The evening before doing a Fedora upgrade, I do a user data back-up. I
do it as a data project in K3b to burn a DVD/Blu-ray (BD-R). I always
"test" the back-up immediately after it's done.
On April 07, 2021, I did such a back-up. I upgraded from f-32 to f-33
the next day. Today, when I put the disc into the drive, it
automatically mounts and asks if I wish to view contents in Caja. In
Caja, I successfully viewed an image stored on the disc, launched in
Firefox an html file stored on the disc, and opened in LibreOffice a
LibreOffice file stored on the disc. The disc was successfully
unmounted and ejected when I asked Caja to do so. Also today, if I
launch Files and then put the disc into the drive, it automatically
mounts the disc. In Files, I successfully viewed an image stored on the
disc, launched in Firefox an html file stored on the disc, and opened in
LibreOffice a LibreOffice file stored on the disc. The disc was
successfully unmounted and ejected when I asked Files to do so.
On October 13, I did a user data back-up. Immediately after, I "tested"
the back-up.
1. When I put the disc into the drive, nothing showed up on the
screen. But I then launched Disks, the disc was there and mounted; it
unmounted and ejected the disc when I told it to.
2. When I launched Files and then put the disc into the drive, the "+
Other Locations" flickered once, and that's all. But when I then
launched Disks, the disc was there and mounted; it unmounted and ejected
the disc when I told it to.
3. When I launched Caja and then put the disc into the drive, a
message popped up
"Unable to mount .F33_20211013
An operation is already pending".
But when I then launched Disks, the disc was there and mounted; it
unmounted and ejected the disc when I told it to.
4. When I launched Disks and then put the disc into the drive, the
icon for the drive showed a disc. When I clicked that disc icon, it
showed it mounted. When I clicked the mount path that showed below the
graphic part of Disks, it launched Caja. I then successfully completed
the "test" just as I did with the April 07 back-up disc, except that I
had to use Disks to unmount and eject the disk. Also, I was able to
restore a files from the back-up disc when using the Caja instance
launched by Disks.
I went ahead and upgraded from f-33 to f-34 the next day.
Today, when I repeat steps 1-4 above using the October 13 back-up, I get
the same results.
Both back-up discs are Verbatum MDISC BD-R Blu-ray Disc, 25GB, 4x
speed. Both were written with the same drive.
What went wrong, and how do I fix it?
Thank-you in advance.
Bill.

Growing shared memory leak?
by Jordan Metzmeier
I am trying to determine if a problem I am experiencing is a bug or if
there is something I am missing. Last week I found that 15GB of my
32GB RAM was used by shared memory, causing my system to fill swap.
After about 1hr of trying to discover the reason for this, the only
thing I could find was that `df` was indicating that space was being
used by tmpfs mounted on /tmp, but I could not find files that came
anywhere close to this size.
Now I am inspecting my system after a few days of uptime and have
found that shared memory is slowly growing again. It's currently up to
almost 4GB:
jmetzmeier@localhost:/tmp $ free -m
total used free shared buff/cache available
Mem: 32065 9493 2185 3920 20386 18204
Swap: 8191 2114 6077
When I check df, what's reported as used on /tmp is pretty close to my
shared memory usage:
jmetzmeier@localhost:/tmp $ df -hT /tmp
Filesystem Type Size Used Avail Use% Mounted on
tmpfs tmpfs 16G 3.5G 13G 22% /tmp
However, `du` does not show 3.5GB of files inside:
jmetzmeier@localhost:/tmp $ sudo du -sh ./
32K ./
Does anyone know what could be happening here? Does writing a file to
tmpfs and then deleting it cause the tmpfs to retain that allocated
memory until reboot?
My system is running Fedora 34. I have ensured nothing is mounted over
top of /tmp and hiding files.
Thanks,
Jordan Metzmeier

router silence.
by home user
(maybe OT)
(dual boot: fedora-34 and windows-7; gnome)
Usually, I use my home workstation with a direct ethernet connection to
my modem. A yellow cable goes from the modem to the yellow receptacle
on the back of the tower.
Occasionally, I go through a router. The yellow cable goes from the
modem to the yellow receptacle on the back of the router, and a blue
cable goes from any of 4 black receptacles on the back of the router to
the yellow receptacle on the back of the tower. This has worked fine
for a few years now: for the tower (both Fedora and windows) and for my
ipad.
But now it does not work: not for Fedora, not for windows, not for the
ipad. Fedora shows no connection; I've found no way of diagnosing the
problem. The ipad seems to sense the wifi signal, but there's no hint
of data (all attempts to use the internet time out); I don't know of any
way of diagnosing the problem. In windows, the indicator shows no
internet connection; its diagnostic tool says something about "teredo"
being disabled? deactivated? by the sysadmin.
Using the router last worked in mid August (fedora-33 on my
workstation). I did not attempt to use it between then and this past
Wednesday.
The upgrade from f-33 to f-34 occurred between the last time I
successfully used the router and the first time it didn't work. Is that
just a coincidence, or did the upgrade have something to do with it?
How do I get my workstation, ipad, and the router working?
For the f-33 to f-34 upgrade, the tower was connected directly to the
modem; the router wasn't even powered up. But might f-34 have done
something to the router when I connected them? The router is a D-Link
AC1200; it's between 3 and 4 years old.
Thank-you in advance.
Bill.

F33 => F34 - gphoto2 not working?
by Philip Rhoades
People,
Upgrading from:
F33 / Xorg / XFCE
to:
F34 / Wayland / Sway
seems to have caused gphoto2 to stop working (it does not discover any
device plugged into a USB port) when I plug in my GoPro Black 4 now. I
can't see why Wayland and Sway would make a difference - what else could
it be? I used to be able to plug the camera in, see the red light for
charging, wait until it was fully charged and the light went out and
then push the button to get the USB connection.
I am not 100% sure but the little LCD screen seems to be displaying
something different now - a power plug icon plus the USB icon - I seem
to remember it was different before but Googling didn't help . .
Any suggestions for debugging would be appreciated!
Regards,
Phil.

Re: Does the program llvm break all the hardware or only some of it ?

??? What are "c scripts"? What has the number of "c scripts" got to do
with Fedora crashing? It sounds like you corrupted your machine or
broke some hardware more than anything else.
Llvm is a compiler suite, and has nothing to do with VMs. This does not
make sense on multiple levels.

Startup recovery
by Dave Close
Not sure how to title this issue but I'd appreciate advice. A laptop
running F34 crashed last night and won't start properly since. The
only errors I can see and find in the logs indicate some unknown
issue mounting the /home filesystem. The system has /boot and an LVM
partition with / and /home. / and /boot mount successfully but the
startup drops to emergency mode. After I enter the root password,
I can run "vgchange -a y; mount /home" and /home is immediately
mounted successfully, no problem. I can then issue ^D and the boot
seems to complete. However, the network is not started and no gettys
are running on other PTYs.
It seems apparent to me that there is no problem with the LVM partition
or the /home filesystem. So I don't understand why startup is failing
nor how to discover the true cause.
BTW, and not likely related, but if I try to boot from the latest
kernel (5.14.11), the screen goes very dim after the mode is changed,
making it very hard to see what is going on, and the keys to brighten
the display seem inoperative. Booting from kernel 5.13.19 doesn't
have that effect though the same startup problem happens.
Off to get a COVID booster in the morning so further investigation will
continue after I return.

Any trick to speed up an xrdp server?
by ToddAndMargo
Hi All,
Fedora 32
xrdp-0.9.16-1.fc32.x86_64
Is there any trick to speeding up and xrdp server?
I can watch the pages paint. Windows machines
on the same network with RDP server set up are
twice a fast. AND THAT IS NOT RIGHT!
Many thanks,
