Goes - both, S3 RESUME and disable/enable the output will induce these
warnings, ...

$ xrandr --output DVI-I-1 --off ; xrandr --auto
$ xrandr --display :0
...
DVI-I-1 connected 1920x1080+0+0 ...
...

... with one behavioural exception - after xrandr OFF/ON routine, the mouse
cursor is visible and motile, but the rest of the screen is as blanked.
