bumblebees xorg.conf.nvidia

Using bumblebee with a nvidia discrete card.

intel-output-virtual -b works fine.

As nvidia exports 2 displays: VGA-0 and HDMI-0, intel-output-virtual export
both as VIRTUAL1 and VIRTUAL2.
This is expected.

As this is a optimus setup, VGA-0 does not really exits.


So, in order to get it right this /etc/bumblebee/xorg.conf.nvidia is attached.

This solves the problem:  nvidia only have HDMI-0 (VGA-0 is gone).
And it now corresponds to VIRTUAL1.


The problem is that intel-virtual-output is exporting more modes than it
exists.


When plugin 1280x1024 display this is what xrandr sees in the nvidia xorg:

$ DISPLAY=:8 xrandr 
Screen 0: minimum 8 x 8, current 1280 x 1024, maximum 16384 x 16384
HDMI-0 connected primary (normal left inverted right x axis y axis)
   1280x1024      60.0 +   75.0  
   1024x768       75.0     60.0  
   800x600        75.0     60.3  
   640x480        75.0     59.9  

And this is what intel-virtual-output exports:

VIRTUAL1 connected (normal left inverted right x axis y axis)
   VIRTUAL1.658-1920x1080   60.0  
   VIRTUAL1.638-1280x1024   75.0  
   1280x1024      60.0  
   VIRTUAL1.659-1280x720   60.0  
   VIRTUAL1.639-1024x768   75.0  
   VIRTUAL1.660-1024x768   70.1  
   1024x768       60.0  
   VIRTUAL1.641-800x600   75.0  
   VIRTUAL1.661-800x600   72.2  
   800x600        60.3  
   VIRTUAL1.643-640x480   75.0  
   VIRTUAL1.662-640x480   72.8  
   640x480        59.9  


note that this problem only exists when avoid the unexistent VGA-0 in nvidia
xorg.  When VGA-0 is present, intel-virutal-output exports the correct modes.
