My Nvidia driver at Fedora (now 27) produces many problems with non-existent VGA display. I have a display attached to DVI. Years ago I plugged in for a short time a second VGA monitor, unplugged it forever, but Nvidia card/driver still remembers it. This make many problems when Linux try to use 2-display configuration with 1 display. Dmesg writes: "WARNING: GPU:0: Unable to read EDID for display device VGA-0". How to make it forget this VGA forever?

Yes it's disabled in nvidia-settings, problem is that card remembers it anyway.

This makes Gnome3 in Fedora 27 unstartable, I see only cursor on black screen. KDE, MATE and Cinnamon do work.

This is an Nvidia bug—"a known issue with some bioses" according to

Gnome developers don't have much to say:

Still have to "cp /root/.config/monitors.xml /var/lib/gdm/.config/" in Fedora 29 to make Gnome work. Fedora Gnome also tend to forget this sometimes and make me fix again. (note, Ubuntu have it fixed ever)

Solved Gnome3 startup, but not "WARNING: GPU:0: Unable to read EDID for display device VGA-0" in dmesg during all day and night
