SUMMARY

I upgraded to Plasma 6 on my laptop yesterday (KDE Neon), and encountered a lot of the issues others seem to be reporting: black screen with no desktop, KRunner errors, no logout from GUI, etc. I managed to get the computer to a mostly usable state after running:

sudo apt autoremove
sudo pkcon install libdecor-0-0
sudo pkcon install libsdl2-2.0-0
sudo pkcon install plasma-desktop
sudo pkcon install plasma-desktop-data

As suggested here: https://discuss.kde.org/t/plasma-6-update-desktop-wont-load/10942/16

Anyways, once I actually had a taskbar again, I went about pinning all my usual applications to it & rearranging them how I like. Next time I booted the machine, all my pins were gone and the taskbar applications had been reset to default. I've turned the computer off and on now a number of times, and it keeps resetting each time.

Note that the whole taskbar didn't reset. It's still at the size I want it & in the position I want it, but I'd have to re-pin the applications.

STEPS TO REPRODUCE
1. Pin applications to taskbar & rearrange per preference
2. Turn off computer (`poweroff` command since GUI broken, see: https://bugs.kde.org/show_bug.cgi?id=481938)
3. Turn computer on

OBSERVED RESULT

Observe that taskbar pins and order have been reset

EXPECTED RESULT

Taskbar stays as it was set.

> `poweroff` command since GUI broken

This will end up being the cause. Changes are saved when Plasma shuts down cleanly, and when you shut down the computer like this, it force-quits everything and Plasma doesn't get a chance to save the changes.

We can improve this; see Bug 481113.

Comment 2 gigastarcraft2 2024-03-07 20:52:07 UTC

I have the same issue and I have no problem shutting down a PC normally. The this is though sometimes I manage to add a shorcut and it stays. Most of the time it just does not add any new apps.

Sync config to disk when values change

When client code calls Plasmoid.confiuration.a = b the value in the
KConfigPropertyMap changes, but the underlying KConfigSkeleton does not
have any signals emitted until that value is flushed.

We need to connect it to the existing mechanism to sync changes after a
timeout.
