[Bug 1849084] Re: Freeze on system-resume caused by kwin and amdgpu driver

[Pietrek B.]

Good news. I was able to work-around this problem by disabling DRI 3:

#nano /usr/share/X11/xorg.conf.d/10-amdgpu.conf
Option "DRI" "2"
I also added:
Option "TearFree" "true"

to mitigate any screen tearing, although that was for purely cosmetic
reasons.

See if this works for you and report back, please.
