i-v-o debug log

Hello,

I'm noticing some more bugs in intel-virtual-output. The setup is the same as in bug 79994.

When I first start the discrete GPU and i-v-o with no outputs connected, then plug in a display, this display will still show as disconnected in
$ xrandr
however, when I run
$ xrandr -d :8
i-v-o then correctly declares it as connected on :0. Shouldn't running xrandr on :0 suffice for i-v-o to proxy that query to :8?


Additionally, when I disconnect the display, :0 is also not notified until I run
$ xrandr -d :8
at which point i-v-o runs into a bug and stops functioning properly (see the attached log)

Ah, if it is not happening until you run xrandr -d :8, it is the nvidia GPU not performing hotplug detection and sending that event onwards.

Unfortunately, I haven't thought of a way to detect when crandr is run on :0 to then query :8 instead.
