Public bug reported:
Im on Ubuntu 20.04.1 with an AMD Ryzen 7 4800h CPU and a Nvidia GTX
1650ti [Mobile] GPU using nvidia-driver-450
Kernel is up to date (5.9.3)
When my laptop boots, the log in screen flashes black and quickly back
on until i log in. When i reach the desktop the flashing stops. Still,
having the screen flickering on the log in screen is very annoying.
As far as i can tell, the laptop doesn't have any further screen issues.
Thanks in advance!
