Public bug reported: display is flickering and not responsive from login screen, before even typing anything.
This happens with kernels newer than 5.8.0-48-generic, i.e -49 and -50. On the occasion I was able to boot in, I was using a recovery mode and display was deemed unknown. I am not sure if this is because of recovery mode settings.
