Broken GDM after letting initial setup idle for a while
I'm installing Fedora 32 on my Dell XPS 9343. After booting for the first time I let the laptop idle for a while (I was busy). When I came back, it was powered off (suspended). After turning the laptop on, I was greeted with an empty GDM:
Opening the top-right menu resulted in all sorts of glitchy behavior:
That's bottom of the screen black, and the menu is blurry and the animation frames are displayed on top of each other.
I found no way out of there, but pressing the power button twice (presumably to suspend and unsuspend the laptop again) brought me back to the initial setup where I was able to complete it fine.
