Unplugged display sticks around causing "phanton" display (Nvidia proprietary driver, sway, kanshi)

[leosunmo]

Hey!
I've run into a weird issue where a real physical display that I am no longer plugged in to sticks around even after reboot.
This causes gnome-settings and kanshi to think there's an extra display. regolith-displayd is generating kanshi config as if this display was plugged in and wlr-randr is reporting the display as active.

It seems like this could be an issue with the Nvidia driver's keeping it "open" or "active" for some reason when searching the internet, but I haven't found anything concrete.

Trying to disable it in gnome-settings doesn't seem to work, and regolith-displayd is still generating kanshi config for it.

Any pointers and similar experiences would be greatly appreciated!
