"journalctl -b | grep kwin" output
SUMMARY
After suspending the computer with an external display attached, the
kwin_wayland process crashed.
OBSERVED RESULT
When waking up the computer from sleep, the login screen briefly appears before
switching to a black, terminal-like screen. I am able to type into this screen,
but the system does not respond to any input. I can access tty, but it is not
possible to interact with plasma in a functional way. If I execute "killall -9
kwin_wayland" from the tty, I am then returned to the login screen and
everything operates as normal, except I am unable to access tty again after
this step.
The bug is highly reproducible. It appears only when using Wayland with an
additional display attached through the HDMI port. This happens if I put the
computer into suspend manually, as well as if I leave it to suspend itself over
time. When using the built-in screen only or when using X11, the computer wakes
from sleep normally with no issue. "nvidia-smi" works correctly as well.
I have been using the same hardware configuration for months with no issues.
The bug appeared after the last update - maybe OS related.
