Public bug reported: After an upgrade with focal-proposed this morning, I am unable to set any scaling for any of my monitors without the monitor turning blank for 15 seconds and reverting to 100% scaling.
I am using X11 with gnome and proprietary nvidia drivers on Focal. I have 3 monitors attached, all 4K, and my usual setup is to enable fractional scaling, and set all 3 monitors to 150% scaling. Now however, I cannot change the monitors to use any scaling, and even if I disconnect 2 of the monitors to only have a single monitor I still cannot use scaling. Finally note I am just using the Settings window, I haven't fiddled with xrandr at all manually.
