After resuming from suspend instead of KDE's lockscreen I was greeted only by
my wallpaper and mouse cursor (responsive). I switched to another tty (it
worked, I could log in) and back and this time it was only black screen, after
another tty switch xserver crashed. After that I was able to start another X
session.
This is what happened this time, but honestly I can't use my laptop for 2 days
without experiencing, at best, freezing of my desktop for a few seconds or, at
worst, forcing me to reboot using sysrq. I can't reliably reproduce it, seems
to happen at random, and may not always be a "GPU Hang", I also saw messages
like:
WARNING: CPU: 0 PID: 500 at drivers/gpu/drm/i915/intel_display.c:3857
intel_atomic_commit+0x1459/0x1460 [i915]
Removing stuck page flip
followed by a backtrace, but was too lazy to report.
Archlinux x86_64
Kernel 4.8.2
