I found the behaviour occurring in a more specific case. Steps to reproduce:
1. In: Settings > Power > Power Saving 2. Set "Dim Screen When Inactive" to "True" 3. Set "Blank Screen" to "1 minute" 4. Do nothing for 1 minute 5. After screen turns off completely, press any key When the screen turns back on it is stuck. I am running the latest kernel 5.13 - 35 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1961608 Title: [amdgpu] Screen freeze after wake from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.13/+bug/1961608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
