backup tips: dump/restore
by Bill Cunningham
Hello all,
Some time back I asked for opinions on backups. I had a lot of good
opinions. I tried to backup some directories with dump. Which seemed to
me to be quick and for what I was altogether looking for, for ext 2/3,
pretty good. A 16GB filesystem was copied to a level 0 dump at around
1.5 GB. So it seems.
I have several favorites, but in regards to dump, for those that
are familiar with it; I did a level 0 dump and before I try restoring an
erased partition I though I would clean up a few questions.
As far at the partition's bootsector, would that happen to be in
the dump file? And I am pretty sure partition table entries or any of
the MBR are not saved. Timestamps and uuid type data of course I would
not see to be saved. Although on my fstab, I use simple /dev/sdXX
entries (/dev/sda1) not uuids. device.map might have to be regenerated
too to get a booting system.
I did not leave out anything system wise specifically by cli
options. /var, /sys, /run, /tmp, /proc I am assuming are in the level 0
dump. The switches I used were:
dump -0uv -e {some inode directory entries, not system specific} -f dmp
Any tips on what I should save or expect to need to change when
restoring this?

Askfedora
by belaz＠tuta.io
Hi there!
What the shit is going on with Askfedora? I've registered on Fedoraproject, but when I try to login to Askfedora with my credentials, it gives me some crap about expired authentication token. Although I'm not logged in and can't have any token, let alone expired.

AnyOne on this list using Fedora Project Silverblue or Project
Discourse silverblue
by Jack Craig
i have been using lists.fedoraproject.org. for support F20 -> F34
My platform environment is a small home system.
i just read about Fedora 36/silverblue (immutable) &
my inclination is to install silverblue, add flatpak's,
and move on to verify F36 silverblue
i also have a list of necessary application files for F36, that I need to
verify before I move on.
these include:
Firefox
including F36 OS +utils
bash shell +(.XXX)
OSB->studio
pipewire audio
http/https
certbot
ffmpeg
image view
files
perl
zoom
My questions include; is anyone on this list using the silver blue desktop
app?
If yes, then...
how easy is it to recover to an earlier version backup/reinstall user files
how stable are the bind & activity logs
how stable is Fedora 36 (silverblue) ??
would you recommend a migration to F36 silverblue now or wait for awhile??

Fedora 36: How do I tell sound to NEVER use a mic?
by Thomas Cameron
I have two mics, one on my Brio web camera, and one on my motherboard.
Every time I boot up, the Brio mic is selected, and I have to manually
go in and tell the audio mixer that I want the onboard mic to be used.
Sometimes I forget, join a WebEx or similar, and they are hearing me
through my Brio, and that mic SUCKS compared to the one I have plugged
in to the onboard sound card. I've set the onboard mic to be the default
more times than I can remember, but when it reboots, the Brio mic is
selected again. This is driving me nuts!
What on Earth do I need to do to make the onboard sound card mic be the
main/only one used?
I am using Xfce, if that matters. When I fire up the mixer, it's using
pavucontrol.
If it matters, I have upgraded this system from F33 through F36.
Thanks!

virt-manager alt-click passthrough?
by Alex
Hi, I'm using virt-manager to connect to a Windows 10 virtual machine,
where I'm using photoshop.
I need to send an alt-click key for some functions, but virt-manager is
instead interpreting them. It isn't among the pre-configured options that
can be sent. Is there a way to remap the alt key or alt-click combination
so I can send it through to the virtual machine?
I've also tried the RealVNC client/server trial, and I can't get that to
connect at all. It does appear qemu/realvnc server is listening on 5900:
tcp 0 0 127.0.0.1:5900 0.0.0.0:* LISTEN
-
qemu is also configured to listen (-spice port=5900,addr=127.0.0.1). I've
also verified I can connect to port 5900 manually, so a Windows firewall is
not the problem.
Any ideas greatly appreciated.

Chromium freeworld - heavy cpu load
by lejeczek
Hi guys.
Do you use Chromium Freeworld - I use this one hoping I get
full HW acceleration with it.
Recently I get relatively high CPU load with it and I wonder
if it is only me? (about 12 windows with a few tabs each,
also other apps up & running at the same time)
I think it's happening since 5.19 kernels and in case
hardware matters - I'm on Lenovo's Thinkpad E14 gen2 with
AMD, which laptop I gave firmware update recently.
many thanks, L.
