There is something wrong with the Power saving's "Blank screen". I've recently upgraded to 20.04 from 18.04. Blank screen is set to activate after 4 mins of inactivity. The problem is that the screen is going blank, but the mouse cursor is still shown and prevents monitor from suspending.


Any idea how to fix that?

It seems this happens quite often with AMD GPUs + some HDMI connected monitors and it is caused by hotplug events.


TL;TR:
Boot your linux with amdgpu.dc=0 in the grub's command line.
