            Bug ID: 93795
           Summary: G98: GL(X) compositing - XRandR DPMS trouble
           Product: xorg
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: pomidorabelisima-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org

The case with the Xfce GLX compositing is,
output disablement/enablement via xrandr:
$ xrandr --output <output> --off ; xrandr --auto
produces unusable session screen - the mouse cursor is visible and motile, but
the rest of the screen is as blanked,
and the only thing left is to zap the xserver and re-log.

Both, Xfce(Xfwm) XRender compositing and DRI3, are NOT problematic in this
sense.


The case with the GNOME GL compositing is not essentially different,
output disablement/enablement via xrandr produces clutter/mutter/scooter
breakage,
thus gnome-shell terminates with signal SIGSEGV thereby reappears display
manager greeter screen.

The case with the KDE GL compositing is comparable with the Xfce one.

GLX: KF5 XRandR DPMS


Screenshot postquam output enablement
$ xrandr --output DVI-I-1 --off ; sleep 5 ; xrandr --auto ; sleep 5 ; import

GLX: remaining "fragment" of the screen can be seen in the top left corner,
session screen is unusable

XRender: KDE is literally falling apart, but the session is still usable
