A couple more data points. I installed and booted a 5.19.17 mainline kernel (from the ubuntu mainline kernel archive) and the static started immediately. I booted the 5.15.0-52-generic kernel left over from ubuntu 20.04 and haven't had any problems with static or full screen video after 30 minutes.
This seems to point toward a kernel/driver issue rather than gnome- shell. ** Package changed: gnome-shell (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1995320 Title: [amdgpu] intermittent green static To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1995320/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
