Bug Description

I got some laptop having optimus/hybrid GPUs setup : AMD Vega 8 ( Raven Ridge ) + Nvidia GTX 1650 GPUs and a display having refresh rate of 120Hz.

Whenever I shut the laptop lid or it auto-suspends it catches screen flickers when it wakes up.

I think it's some kernel issue some deadlock maybe.

I already filed a bug on fedora bugzilla forum for the same aswell.

Here is the link for the same :


I hope it gets' fixed this time :)

I also notice you're not using the Ubuntu kernel. Please try the standard Ubuntu kernel (5.4) as well as newer versions like 5.7-rc3 ...
