--- Comment #4 from stephan.lae...@protonmail.com ---
Soooooo... i could not resist the temptation to try to make myself useful. So
here is what i did:
I compiled Gentoo with -Og -ggdb and with installsources as described here
https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces and here
https://wiki.gentoo.org/wiki/Debugging#Per-package . I installed debug for the
entire system, not just Plasma.
I then wrote a script to reboot my PC countless times (actually 235 times), and
tried to catch the bug. When i turned my monitor back on to end the reboot
loop, i was greeted by the crash reporter. I looked into
/var/lib/systemd/coredump and found that this was the only new crash of plasma.
So i thought maybe it has something to do with me turning on the monitor, and
not with me rebooting.
I rebooted, turned off my monitor, and waited until roughly the time where the
login would occur (After the systemd wall of text).
And there it was: The crash reporter.
Unfortunately i do not know how big the time window is. It is at least 8
seconds after login (My reboot script reboots 15s after login), but it might be
larger. Maybe i will figure that out tomorrow.
STEPS TO REPRODUCE:
Reboot your PC with the monitor off. Turn the monitor on about when the Plasma
login happens.
I created 5 crashes (with reports):
1. Accidential crash when i turned the screen on to end the boot loop script, i
was greeted by the crash reporter. Plasma looked normal.
2. First attempt to reproduce crash. If i remember correctly Plasma looked
normal.
3. Second attempt to reproduce crash. If i remember correctly Plasma did not
show and the screen went to sleep. I tried CTRL+ALT+(F1-F4), but no reaction. I
then did CTRL+ALT+SysReq+R, and then CTRL+ALT+F4 gave me a console and
CTRL+ALT+F1 gave me Plasma with the crash reporter. I think this was also the
crash where my CPU/Memory/Clock(Time) widgets in the taskbar were gone. But
maybe this was the second attempt. I don't know.
4. Third attempt. Like the second one.
5. Fifth attempt. Like the second one.
The crash can be reproduced every time (4/4).
I tried to submit this using the crash reporter, but there seems to be a bug
with the crash reporter. I will open a different bug report for that.
OS: Gentoo
Graphics: AMD (FOSS drivers), Wayland, DisplayPort (2560x1440@165, VRR)
