Thanks for the reply! I tried your steps: - When using wayland, the flashing also doesn't occur on the desktop - Kernel 5.4.0-52 doesn't boot at all - Kernel 5.8.4 does boot, but the flashing is still there
Editing the gdm3 config file however, did fix the flashing on the log in screen. On both the 5.8 and 5.9 kernel edit: it seems the config file didn't work 100% as some of the times the log in screen still flashes. So this is better, at least, but still not perfect. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1902749 Title: [amdgpu] Log in screen flashes on and off until I log in Status in mutter package in Ubuntu: Incomplete Bug description: 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.
