Description Oliver Klee 2022-03-31 12:52:43 UTC

SUMMARY
In a Wayland session, if a keyboard shortcut is used to activate standby/sleep, the system shortly goes into standby (as seen be the power LED) and then directly wakes up again.

This problem does not occur if standby is triggered using the KDE menu or via systemctl suspend, and it also does not occur on a X11 session.

STEPS TO REPRODUCE
1.  Log in to a Wayland session.
2. Set a keyboard shortcut for activating standby.
3. Use the keyboard shortcut.

OBSERVED RESULT
The system shortly goes into standby (as seen be the power LED) and then directly wakes up again.

EXPECTED RESULT
The system shortly goes into standby and stays that way until I press a key.

Does it work as expected on X11?

Comment 2 Oliver Klee 2022-04-02 19:39:41 UTC

Yes, on X11 it works as expected.

Comment 3 Oliver Klee 2022-04-04 10:46:53 UTC

Would it help if I created some logs (which?) for triggering standby via the KDE menu vs. via the keyboard shortcut?

KWin doesn't handle device wakeup, that's on a kernel or even firmware level. FWIW I can't reproduce this issue either though
