Hello all!
I’m having a problem with Fedora 40 KDE. I have three (identical) monitors, and every now and then the two non-primary monitors boot with a resolution of 640x480. If I go to Display Settings, I can’t change it to any other value. I learned that if I unplug the monitors and plug them back in, the problem is solved. What can be causing this?
