- This module needs a running x-server on a given display in
order to successfully call xrandr. Returns the dictionary
"xrandr", wich contains all screens with output states,
connected displays, EDID info and their modes and a
recommendation for the best fitting tv mode, the dictionary
"xorg" with a recommendation for the primary and secondary
output and a "drm" dictionary whose "primary" key associates
the primary device name of the drm subsystem with the one from
the xrandr output by comparing the edid data and a list of
"ignored_devices". Note that the proprietary nvidia driver
doesn't support KMS/drm, so in this case the dictionary is
always empty.
