Bug ID: 513412
Summary: The system freezes when the monitor automatically
turns off on Wayland.
Classification: Plasma
Product: plasmashell
Version First 6.5.4
Reported In:
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Power management & brightness
Assignee: [email protected]

Target Milestone: 1.0
SUMMARY
I recently switched to Wayland after replacing my AMD Radeon R7 240 with an AMD
Radeon RX 550. That was about 20 days ago, and the system worked fine at first,
but about five days ago I noticed a behavior that became clear today: when the
KDE system is configured to turn off the monitor after a certain amount of
time, and after that time the system tries to turn off the monitor and
gradually reduce its brightness, the system freezes completely. The only
solution is to press the reset button on the computer. After rebooting, the
system works normally only until the next attempt to automatically turn off the
monitor when the computer is idle. In this situation, I had to disable the
monitor auto-off feature, because the system only works properly in this case.
STEPS TO REPRODUCE
1. The system is configured to automatically turn off the monitor after a few
minutes.
2. When the timer expires, the monitor goes half dark and the system freezes
completely.
OBSERVED RESULT
The system freezes completely.
EXPECTED RESULT
The monitor should smoothly turn off and turn on again at the user's request
from the mouse or keyboard...
