Public bug reported:
Just upgraded from 20.10 to 21.04 and the system became unusable.
First login after upgrade, screen flicked every 6 seconds noticeably
making the system unusable. Tried to log out, system froze.
Several more attempts, same flicking issue. Tried to use xorg instead of
wayland, it worked once. No screen issues.
Only once though :( After that, computer starts normally but freezes in
the login screen. Or freezes just after login if I manage to type the
password fast enough.
Back to kernel 5.8.0-53 and xorg, everything looks ok.
