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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849084 Title: Freeze on system-resume caused by kwin and amdgpu driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kwin/+bug/1849084/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
