Default Switching between DVI and VGA

Hi

When using Linux on my MaxBookPro (Santa Rosa, 8600M GT), I can use the DVI output without any problems. However, if I want to use a projector, or another VGA device, I have to edit xorg.conf and explicitely set
Option "ConnectedMonitor" "DFP-0,CRT-0"

Just restarting X with the DVI-VGA adapter doesn't do anything - no output will be displayed, but the X log file looks like everything is ok - both displays are detected, the correct resolutions are detected, but no output on the external display.
It can be pretty annoying to have to restart X just to switch to VGA (and back again), so I was wondering if there's something I can do? Or does anybody know if support for switching will be added to the driver at some point?

Thanks,
Joakim

Don't use ConnectedMonitor. Try using "UseDisplayDevice" "CRT" instead. This will tell the driver to use a CRT when one is detected, and it'll fall back to its normal logic if there isn't one.

You should be able to use the display configuration page in nvidia-settings to switch display devices.
