Loose xfce desktop when HDMI disconnected
#1
Hi,

I have just installed LL 2.2 on a new Intel based mini PC.
I have it connected directly to a monitor(input #2) via HDMI
The monitors got 2 HDMI inputs, input #1 is my main PC.

If I use the the monitors "switch source input" I can switch between the 2 PC's,
However If I switch from the "New" PC to the other PC and back I loose the
"New PC's" Desktop, I go back and it's black.
If I do a crt alt f3, I can get a system prompt and do a restart of the Desktop.

The other PC is fine, I can go back to that and it's fine, that is running LL 2.0

So the new PC does not like having it's HDMI output switched.

It's not screensaver/display settings in LL 2.2,
I can leave the New PC connected to display for periods of time, screen goes blank
move mouse, tap keyboard and it's back.

Any ideas welcome. (inxi -F below)

Thanks... Dave
