Broken system's xrandr.

Note that both VGA1 and eDP1 are shown as connected, but no crtc is registered for eDP1.

The user attempted using both the gnome settings capplet, and the xrandr command line tool. For the latter he adds:

"""
here is aditional info:
xrandr --output eDP1 --auto --output VGA1 --auto --same-as eDP1

i get this error:
xrandr: cannot find crtc for output eDP1

in Xorg.og i get this:
[ 1656.684] (WW) intel(0): flip queue failed: Device or resource busy
[ 1656.684] (WW) intel(0): Page flip failed: Device or resource busy
