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)
