workaround from bug 1552040.

  [drm:intel_display_resume [i915]] *ERROR* Restoring old state failed
  with -22

Status in linux package in Ubuntu:

Bug description:
  This error appears in my journal quite often after resuming laptop
  from suspend and when un-docking the machine in the meantime.

  When docked, I usually only enable two external displays. Un-docked I
  only have the built-in display on the laptop. This was working
  flawlessly in 18.04 but is extremely buggy now after having upgraded
  to 18.10 for some reason.

  When this happens, my screen(s) remain pitch black. Switching to TTYs
  and back does not help. CTRL+ALT+F1 gives me the GDM login, but when
  entering password it seems it switches to TTY2 (or whatever is at
  CTRL+ALT+F2), and the screen(s) remain black.

  Logging in in a TTY and trying to "DISPLAY=:0.0 gnome-shell --replace"
  does not help.

  <super>+P does not work (is this shortcut combination removed?).

  At last when I ran "xrandr --auto" the session I had crashed and I had
  to re-login, but at least this time I got my desktop.
