I’m on kernel 5.10 and for whatever reason my external monitor stopped working. It shows up fine in xrandr, and I can even connect it and move my mouse or windows into it, so it functions as if the display exists. However, the display is completely blank. I’ve read a bunch of other similar threads, but nothing I try seems to change anything. The display works fine in Windows, and even works in an earlier (I think 4.4) kernel I have installed. Here is some more info:
$ inxi -Faz
