Please try the instructions in comment #27 again. If you are unable to remove the PPA then I would ask you to please reinstall Ubuntu before logging any more bugs. And don't use PPAs if you are not familiar with managing them, or if you need to log bugs.
If you do reinstall Ubuntu then be sure to backup all your data first. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1891470 Title: [amdgpu] White screen on resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1891470/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
