In my case the problem is severe. I can see login screen, but when I log in I see a white noise screen. It renders my computer unusable. That is unless I use older kernel.
There is how to do it: When your computer boots press escape (UEFI boot) or shift (BIOS boot). You may have to try several times to press it in right time. A menu should appear. Choose option 'Advanced options for Ubuntu'. Then choose 'Ubuntu, with Linux 5.11.0-46-generic'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958412 Title: [amdgpu] Flickering/noise on screen started in kernel 5.13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.13/+bug/1958412/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
