Bug ID: 442846
Summary: Plasma Wayland Freezes upon unlocking screen after
leaving laptop with intel graphics idle for long time
Product: kwin
Version: 5.22.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: pizzad...@linuxmail.org
Target Milestone: ---
SUMMARY
I use Fedora 34 KDE on a Thinkpad T580 with an i5-7300U CPU and Intel HD
Graphics 620. When I lock the screen, and leave the laptop for a long period of
time (a few hours), there is a 50% chance when I come back, and after unlocking
the lock screen, my whole system will be in a frozen state. This only happens
on wayland. When the system is in a frozen state, I can't ctrl+alt+f[number]
either to access a tty. There is no response from any key I press. If I'm
lucky, and I spam a bunch of keys, the system will unfreeze. Most of the time I
have to force poweroff though.
The problem doesn't happen if I don't keep the system on the lockscreen for a
long period of the time. The problem doesn't happen if I close the laptop lid
and let it sleep instead of keeping it open.
STEPS TO REPRODUCE
1. On wayland, Leave intel hd graphics laptop on lock screen for long perioid
of time
2. Come back to computer and unlock the screen
3. Full system freeze
OBSERVED RESULT
System freeze upon unlock after idle for a few hours
EXPECTED RESULT
System not to freeze
