Just an additional remark, I can actually set the DPMS state in
/sys/class/drm/.../dpms back to "On" with (through SSH):

XAUTHORITY=/var/lib/xdm/authdir/authfiles/A\:0-4LXCpv DISPLAY=:0.0 xrandr
--newmode 1280x1024 108 1280 1328 1440 1688 1024 1025 1028 1066 +HSync +VSync
XAUTHORITY=/var/lib/xdm/authdir/authfiles/A\:0-4LXCpv DISPLAY=:0.0 xrandr
--addmode VGA-1 1280x1024
XAUTHORITY=/var/lib/xdm/authdir/authfiles/A\:0-4LXCpv DISPLAY=:0.0 xrandr
--output VGA-1 --mode 1280x1024
XAUTHORITY=/var/lib/xdm/authdir/authfiles/A\:0-4LXCpv DISPLAY=:0.0 xset dpms
force on

However, the display will stay remain turned OFF.
