"Mirror displays" is disabled in xfce4 Display window

[Nohl Attila Rajmund]

Until a couple of months (or just weeks) it was possible to turn on mirroring, but now the "Mirror displays" checkbox is always disabled and I cannot turn on mirroring with external monitor. I'm using a Dell Latitude 5420 and the external monitor is connected via HDMI. The very same setup used to work not long ago. I'm using Ubuntu 22.04.1 LTS.

Same problem here since a few weeks... Was working perfectly a few weeks ago...

NOTE: I have a PRIME machine, with both Intel & Nvidia GPUs... I recently switch to nvidia-on-demand to intel-only, then back. Without rebooting (That's really shitty if I have to reboot everytime I want to switch GPU :( ).
