X forgets monitor configuration when HDMI cable was unplugged and then re-plugged on a running system

[Daniel LaSalle]

Running 22.04.1, I am using a the following (See 01.png) monitor setup.

When I unplug the HDMI cable from my video card and plug it back, the monitor has lost it's orientation (See 02.png)

If I then reconfigure the monitors I get the following (See 03.png). However the changes are taken into consideration and the display is back to normal.

Yet if I continue dragging the monitors around in that same interface odd interface behavior start happening more frequently (See 04.png).

So this could perhaps be split into 2 bugs. I will let you decide.

Thanks,

The same exact behavior if I switch from HDMI to DisplayPort using the same system and methodology.
