The logout in Plasma 5.4 takes as long as it took in 5.3 - with 5.3 crashing, reloading, then finally logging out. With 5.4 the crash was fixed, but it still takes as long until I either get to sddm or the PC shuts down/reboots. The whole process takes about 8 seconds to complete. Visually, I can only see a black screen with a mouse cursor on it.

Here is the log snippet for a restart:

A few things I can see:
- @01:19:32 there is a 6 second pause where nothing seems to be happening. What is it doing?
- @01:19:39 kactivitymanage segfaults
- right after that some processes seem to have not gotten the message the system is going down

Ignoring the crash, if there wasn't for the 6 second pause, then I'm sure I wouldn't have noticed anything.
I'm running newest packages and the nv 340xx driver. Should I report this as a bug?

A good idea would be reporting the kactivitymanagerd crash, if you find a way to get a backtrace.

I want to dig this out again because I also encounter this delayed logout/reboot.

Right after starting KDE and then log out to console, or shutdown, or reboot there is a (in my case) ~10 seconds delay. I can see how KDE quits kwin, the screen gets blank
and from there is a 10 seconds delay of whatever KDE is doing in that 10 seconds, then after that I can hear the KDE "bell" and my init system starts to do its job to reboot/shutdown etc...

Well, 10 seconds is not much but it feels awkward and 2001 when my PC had a very slow mechanical HDD... that doesnt fit into 2021.

I would like to find out what causes this delay but I dont know where to start.

My current system is:
Operating System: Gentoo Linux
KDE Plasma Version: 5.21.5
KDE Frameworks Version: 5.82.0
Qt Version: 5.15.2
Kernel Version: 5.10.52-gentoo
OS Type: 64-bit
Graphics Platform: X11
Processors: 32 × AMD Ryzen 9 5950X 16-Core Processor
Memory: 31.3 GiB of RAM
Graphics Processor: AMD Radeon RX 6900 XT

Ps: Forgot to mention that in ~1 of 10 cases KDE quits immediately with the bell sound and logout/reboot works as expected...
