nVidia

I know, I just ranted about it. However, it would seem that the Xorg driver can do more with the video card in my laptop than would appear at first sight. If I plug a VGA monitor to the mini-DVI output of my PowerBook and start X, then the nv(4) driver seems to detect it. Behold the diff:

[...more data about the monitor goes here...]

The nv(4) manpage also contains this bit:

       Option "CrtcNumber" "integer"
              Many graphics cards with NVIDIA chips have  two  video  outputs.
              The  driver attempts to autodetect which one the monitor is con‐
              nected to.  In the case that autodetection picks the wrong  one,
              this  option  may be used to force usage of a particular output.
              The options are "0" or "1".  Default: autodetected.

... but when I set that to 1 in the Section "Device" of my xorg.conf, it still uses the internal monitor of my laptop. Am I missing something?
