Bug Description
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.

Thank you for your bug report, if that's specific to newer kernels then it's an issue with the kernel, reassigning to linux
