[No responses from qubes-users, trying here next!] https://github.com/QubesOS/qubes-issues/issues/3558 In RC4.0... After suspend/resume Any monitors that were inverted or rotated, will be black. The mouse does move across the screen... but no objects move on this screen. Refreshing the configurations by toggling to another terminal (ctrl-alt-f2) then back again (ctrl-alt-f1), or changing the resolution/position of screens in xrandr/arandr/etc/... will restore the last known image on the affected monitors. Reconfiguring the affected screen to remove invert/rotate settings does restore the image refreshing ability. The monitors behave normal, but I need them inverted. Logging off or restarting X server does not fix the issue. A reboot is needed to restore the desired behavior of having a working and inverted screen. Very problematic as I do need to suspend resume a lot.
Before suspending, have you tried turning off your secondary display(s) (xrandr --output dispname --off) and un-rotating your primary display (ie. getting back to a "clean" state) ?
That's what I used to have to do with my laptop docked: in that case I'd use only my secondary larger monitor with the laptop's display turned off and without turning on the primary display before suspending both displays would stay off after resuming and I would have to type my xscreensaver password and issue xrandr commands blindingly to turn on one of the displays. Note that I write "used to": a kernel update fixed the problem (some weeks or months ago - can't remember) - both displays are now turned on after resume. So the issue was likely not specific to Qubes.
