[Stable Update] 2024-05-13 - Kernels, Plasma 6, Gnome 46, LxQT 2.0, Nvidia, Pacman

After another KDE update:
Most programs open delayed, e.g.
Chromium, Thunderbird…
There is a noticeable delay, especially when opening several konsole windows, also copy & paste actions in kate or kwrite are delayed

The system has been cleaned up after the upgrade, I can’t see any conflicts yet …

Could something be using a lot of CPU? That would cause those symptoms. Have a look using htop.

CPU load is fine … mostly 0.2 - 0.5% us

%CPU(s):  0,5 us,  1,3 sy,  0,0 ni, 97,4 id,  0,3 wa,  0,3 hi,  0,2 si,  0,0 st

looks like a kwin or kde issue …
also this inxi output comes delayed:

Okay, a few days later I’ve noticed one issue with bluetooth. Before the update, my bluetooth headsets paired and stayed connected without issue. Now they connect, and they seem to stay connected, but every few seconds I get an intermittent notification saying “Connected.”

If I’m watching a youtube video, the audio sounds great and never seems to stutter. While watching, I opened the bluetooth-monitor GUI and though the audio seems to stay connected, the GUI clearly shows the device disconnecting and reconnecting. I’m glad that it seems to work, but I confess the repeated notification is a distraction.

Anyone else see this behavior? I’m using XFCE.

Does anyone know how these errors can be eliminated?

Using GtkSettings:gtk-application-prefer-dark-theme with libadwaita is unsupported. Please use AdwStyleManager:color-scheme instead.

plasma-polkit-agent.service: Main process exited, code=killed, status=11/SEGV

Theme parsing error: <data>:2:27: The style property GtkButton:default-border is deprecated and shouldn't be used anymore. It will be removed in a future version

Theme parsing error: <data>:1:42: '-gtk-cursor-aspect-ratio' is not a valid property name

gtk_accessible_text_get_contents: assertion 'end >= start' failed

Are they causing you problems? If not, I expect they can be ignored.


Yes, opening windows, copy & paste action … are delayed

Try a new profile first.

If that works, try a different theme.

Downgrading to kernel 6.6 seems to have fixed the nvidia issues. If I get a crash again, I’ll post there in the other link (see msgs above). For now, thanks for the help.

Hi all,
a few days after the latest major update pamac now shows error messages:

pamac update --no-aur
Synchronisiere Paketdatenbanken...
cp: die Zeiten für '/var/tmp/pamac/dbs/sync' werden beibehalten: Die Operation ist nicht erlaubt                                    
chmod: Beim Setzen der Zugriffsrechte für '/var/tmp/pamac/dbs/sync': Die Operation ist nicht erlaubt
Warnung: task: Ignoriere Paket-Aktualisierung (2.6.2-2 => 3.0.2-1)
Es gibt nichts zu tun.
Vorgang erfolgreich abgeschlossen.

I did not change something manually, and prior to the latest update of libpamac, libpamac-flatpak-plugin and libpamac-snap-plugin I didn’t see these error messages.
Any ideas?

Access rights for the directories mentioned are:

drwxr-xr-x 18 root root 4096 13. Mai 13:02 /
drwxr-xr-x 12 root root 4096 17. Mai 12:17 /var

drwxrwxrwx 3 admin admin 4096 17. Mai 17:45 /var/tmp/pamac/dbs

Files in /var/tmp/pamac/dbs are (user “joerg” is myself, of course…):

Thx for any comment or suggestion.

Not sure about your problem, but on the first glance, that should be in /var/tmp/pamac/dbs/sync

Anyone know what could be causing this?
Happened after the update.

NOTE. If you are going to answer my question, please read my “About me” first.

Ups, thx for your hint - that was my fault when copying the text from xterm to the forum board:
the mentioned files are actually already in …/dbs/sync/ (not …/dbs/
and permissions for /var/tmp/pamac/dbs/sync/ are:

drwxrwxrwx 2 admin admin 4096 17. Mai 18:44 /var/tmp/pamac/dbs/sync/

Sorry - but the described problem still persists…

Do you have a separate user named admin? On my system, those 3 directories are owned by my one (and only) user. I always wondered what would happen if multiple users ran pamac.

Indeed, in my case they are also owned by my only user and not by root.
If they are owned by “admin”, that can explain why the user “joerg” receives an error about permissions. That will of course mean that pamac is concepted as a single user thing which is kind of stupid on linux. In that case you will have to update from “admin”, or root, or just use pacman -Syu.
Not sure if sudo pamac is a good idea as alternative, the experienced users warn against it.

Good point, that is helpful!
In deed, I have multiple users on my system: “admin” is the first “user account” (id 1000), then “joerg” (= myself, ID 1001), and some others, too.
I usually log in to the system using the “admin” account (which has permission to use sudo) for system maintenance or config changes.
For normal “day2day” work I usually use the “joerg” account (which can use pacman via sudoers, and is limited to some other programs otherwise).
I can not remember exactly, but rumor has it that I ran pamac update as user “admin” the last time before the latest big update.
And now I’m trying to run pamac as user “joerg” - which might explain the error messages now.
But: I’m sure that in the past I ran pamac with both accounts successfully (i.e. without error messages), and now I have them…
That makes me wonder what the concept of using pamac might look like: use it with a single user ID only, and never run it with another?
(and of course, I now that running pamac as root is a bad idea - I never did!)
To make a long story short: I changed the owner+group of directory /var/tmp/pamac/dbs/sync/ to be “joerg” insted of “admin”, and the error messages are gone!
Thank your for your help - what remains is open questions in my mind regarding the use cases for pamac (and why its behaviour was changed with the lastest update)?

I am glad we found it. It seems like some bug anyway, because in theory with those permissions it should not matter if you are the owner of the folders or not…but it seems in practice it does.

Because for this big update you need to update it on a special way, don’t use pamac GUI, i hope you have a timeshift snapshot before you updated to rollback your system and follow this steps:

1.Fresh start
2.Log out
3.crtl+alt+f3 to open TTY
4.sudo pacman-mirrors --fasttrack
5.sudo systemctl stop sddm
6.sudo pacman -Syu
and spammed Y to replace everything


Updated today - no problem, everything is fine, but there is one problem. All audio devices are working correctly, but are not displayed in the volume control widget. Does anyone know how to fix this?
