White screen after suspend

Support Graphics & Display

Recently (likely after one of the updates as I do them frequently) looks like I have 2 problems:

  1. My system is unresponsive for about 10- 20 seconds after I see login screen
  2. When my desktop is suspended then after resume, I see white screen and need to restart computer. I can go to other tty using Ctrl + Alt + F<2-6>, but I can’t resume my normal work. Usually a second before I switch to other tty I can see my desktop, but then when I return back then it’s once again white screen

I have AMD 7950x processor and Linux kernel 6.0 . Not sure if it could be related to embedded graphics/drivers

AMD 6800H and Linux kernel 6.1 also have this problem. When re-awakening from hibernation, high-frequency flashing white screen or always white screen occurs. Can only be restored by restarting

I have the same CPU and the same problem with Kernel 6.1.7. This occurs also in somewhat the same manner after I used flameshot to make a screenshot. Then the screen flickers in high-frequency.

Help seems to be on the way though: Flickering or constant solid white screen with kernel >=6.1.4 (#2354) · Issues · drm / amd · GitLab
