G98: GL(X) compositing - XRandR DPMS trouble
Submitted by poma

Description
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.
