Seems like there's a few of these questions, but none of the solutions in the previous questions have helped me.
I have 2 monitors. Both plugged into my GPU (GTX750ti); one via HDMI and one via VGA. I moved the VGA one to the Motherboard as part of setting up GPU passthrough to a VM. I have now moved it back to my GPU, however the monitor no longer sees any input from the card, and is not detected by
xrandr at all.
The monitor still functions perfectly. It works fine during splash and showing the BIOS, it just stops receiving input once the display manager loads.
I am at a complete loss how to resolve this. I've heard of clearing monitor settings through
rm ~/.config/monitors.xml but as far as I can tell I have no such file. How do I either reset things so that Kubuntu auto-detects it again, or else manually tell it the monitor is there?
