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.</pre>
