Bug ID: 507691
Summary: Plasmashell dies on monitor wakeup (wayland)
Classification: Plasma
Product: plasmashell
Version First 6.4.3
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-crash
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
SUMMARY
When my monitors wake up from sleep, Plasma dies. The process is still running
but visually it appears dead -- no task bar or widgets and the desktop is gone
(black background).
I can't reproduce this with only a 1 minute sleep -- it appears that the sleep
has to be for more than some number of minutes (it reproduces for me every
morning).
STEPS TO REPRODUCE
1. Set monitors to sleep on idle
2. Wait some time
3. Wake up monitors by moving mouse
OBSERVED RESULT
Plasma dies (even though process is still running). I see this in the logs:
Jul 31 08:04:43 edison plasmashell[654937]: wl_registry#85: error 0: invalid
global kde_output_device_v2 (7772)

Jul 31 08:04:43 edison plasmashell[654937]: QSocketNotifier: Socket notifiers
cannot be enabled or disabled from another thread
When the process is eventually restarted using `systemctl --user restart
plasma-plasmashell.service` then plasmashell crashes and restarts, and I see
this in the logs:

No crash.

ADDITIONAL INFORMATION
I don't know when this started. Before this, I used xscreensaver but since it
is not well supported on KDE/Wayland I turned that off, and immediately started
experiencing this problem. I would love something like xscreensaver for
KDE/Wayland. Monitor sleep seems to cause so many issues, from GPU crashes to
this type of thing. Plus who doesn' t like seeing funky graphics when they come
back to their workstation?
