Comment 7 for bug 956139

Starting with version 302.17, the NVIDIA proprietary drivers adds X driver support for RandR 1.2 and RandR 1.3.

304.xx are available in quantal but there's nothing we can do for older versions, I tried nvidia-settings and nvidia-smi, both don't return the available ports.

This i what i get with 304.51 on my XPS 1340 (DP + VGA + HDMI, connected to DP):

Screen 0: minimum 8 x 8, current 3200 x 1200, maximum 8192 x 8192
VGA-0 disconnected (normal left inverted right x axis y axis)
LVDS-0 connected 1280x800+1920+0 (normal left inverted right x axis y axis) 286mm x 179mm
   1280x800 59.8*+
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 518mm x 324mm
   1920x1200 60.0*+ 59.9
   1920x1080 60.0 59.9 50.0 24.0 30.0 30.0 25.0
   1600x1200 60.0
   1280x1024 75.0 60.0
   1280x720 60.0 59.9 50.0
   1152x864 75.0
   1024x768 75.0 60.0
   800x600 75.0 60.3
   720x576 50.0 25.0
   720x480 59.9 30.0
   640x480 75.0 59.9 59.9

The ideal solution would be to get rid of the requirements/resource for precise and older series and create the display_resource script for quantal+ as suggested in https://bugs.launchpad.net/checkbox/+bug/992727/comments/6
