Triggering DPMS power-saving affects leased displays
It'd be nice to be able to blank the (desktop) monitors while a VR headset is in use. This bug effectively prevents that.
While a VR headset is in use (or at least some program such as SteamVR's vrcompositor is running), force DPMS blanking via xset dpms force off
. All attached displays will be blanked, including the VR headset. SteamVR will notice that something's gone wrong and will want to be restarted (but see also drm/amd#982 (closed)), and any running game is rendered effectively unplayable.
