microphone
by Patrick Dupre
Hello,
I have a Dell Optiplex 7060
There is only one jack sound plug.
Dell says that I can use it as input or output.
Head phone works perfectly.
If I put a microphone, it is not recognized
I checked that the Audio input/output are enable.
Why?
Do I need to install something else?
Thanks

kde: unable to create io-slave
by Neal Becker
Uh oh, looks like there is some breakage for latest kde update. When I try
to attach a file to an email I get a dialog box saying:
unable to create io-slave: klauncher said: Error loading
'/usr/lib64/qt5/plugins/kf5/kio/file.so'
The usual file choosing dialog box is blank (no files shown).

HandBrake & "Additional Fonts Required"
by Jorge Fábregas
Hi,
I'm in F33 and every time I open "HandBrake" I get a an "Additional
Fonts Required" pop-up in the top bar. I even tried opening it thru the
terminal with "gdb -x" but I don't see anything related to fonts in the
output.
The fonts aren't available and the requested ones are ""Divehi;Dhiveh;
Maldivian" (have no idea why is requesting such fonts).
Does anyone knows how can I get rid of this?
Thanks,
Jorge

by Patrick Dupre
Hello,
I more or less solve my microphone issues (using the front face port), but
audacity yields:
error code: -9997 invalid sample rate
What are the alternative to audacity?
Thanks

Compression on Btrfs
by Patrick O'Callaghan
I did the following:
# btrfs filesystem defragment -czstd -r -v /home
and changed the fstab entry:
# grep /home /etc/fstab
UUID=8e1f7af4-c0bf-434e-b1c4-a9af2c810d56 /home btrfs subvol=home,discard=async,compress-force=zstd 0 0
(this is an SSD, hence the discard-async)
I then rebooted, but find:
# btrfs prop get -t i /home compression
#
(i.e. no output)
and the space usage doesn't seem to have changed.
Is there something I've misunderstood?

systemd-resolved floods the logs
by Jerome Lille
Hi
I've just updated a desktop from Fedora 32 to 33 and after that the
logs are flooded with the following message
systemd-resolved[]: Using degraded feature set TCP instead of UDP for
DNS server 127.0.0.1.
systemd-resolved[]: Using degraded feature set UDP instead of TCP for
DNS server 127.0.0.1.
This machine uses a VPN service that is always on. The file
/etc/resolver.conf has just one line with the nameserver from the VPN
provider. There's no problem in name resolution. Just the constant
flooding of the logs.
What can be done?

Limit size of a btrfs subvolume?
by Richard Shaw
I think this is one of the corner cases for BTRFS as most people want the
opposite behavior, but on one computer I run MythTV and it manages how many
recordings to keep based on the available free space. Once free space comes
down to a certain threshold it starts expiring older recordings.
Obviously this runs counter to btrfs's subvolume method of sharing free
space.
So is there a way to set the "maximum" size of a subvolume? Google has
failed me on this one.
Thanks,
Richard

KDE Plasma desktop won't load
by Temlakos
Everyone:
I sincerely hope someone can help me with this. This morning, KDE seems
to have pushed Plasma 5.20--and the push was incomplete. After I had the
bad sense to force some updates, I found that my SDDM theme was gone,
and I couldn't log on.
Finally I gained enough access to install an SDDM theme--and in the
process roll back Plasma to 5.19. (Ninety-four downloads, 146 MB.)
So then I got my SDDM display back, and could select a user account,
enter a password, and press Enter.
Only now Plasma won't load no matter what I do.
I cannot send any logs, because I literally do not have the kind of
access that would let me copy and paste into an e-mail. I am sending
this on an auxiliary machine.
The contents of .xsession-errors is something like:
kwin_x11: symbol lookup error: /lib64/libkwin...: undefined symbol
plus a very long string that among other things contains the substring
"Weyland" and "Plasma."
How do I get Plasma to load and get past that "symbol lookup error" in
an X session?
If I can't manage this, I'm going to have to spend a great deal of time
doing a "clean install" of F33. I might be able to save my files--I have
a separate drive that I mount as /crypt to make it part of the file
system. But it seems to me that I'm missing a very simple fix.

Backing up Btrfs (was: btrfs or ext4)
by Patrick O'Callaghan
Brief recap: I'm currently using BorgBackup, which among other things
does compression and deduplication. I'm looking at the pros and cons of
changing to Btrfs for backup (I already use it as my main fs). The
backup drives are currently ext4 so would need to be converted.
Now read on.
Following Chris Murphy's suggestion, I looked at:
https://fedoramagazine.org/btrfs-snapshots-backup-incremental/
My question is whether I can use compression and deduplication on the
backup even if these have not been enabled on the original fs. My
instinct is to say no, but I could be wrong.
