Public bug reported:
Software:
Ubuntu 21.04, all updates installed (2021-06-10).
Hardware:
Xeon 1230 v3 (Haswell platform), 16GB ECC ram, AMDGPU (Polaris)
Expected behaviour:
When locking the screen - it turn off and stays off until I touch mouse or
keyboard (I have turned off lock screen notifications)
Actual behaviour:
Display turns on, just a black screen (display backlight on) and sometimes I
can see the mouse coursor. I have no idea what triggers it and don't really
know where to look.
What I have tried:
Different dp outputs and X11 and Wayland. Nothing has helped.
