Interesting, so you don't have /etc/X11/xorg.conf file at all?

I have seen examples like this, but they all start with "execute
`xrandr -q` to see which displays are connected" which in my case
doesn't work. I only see something like this:

$ xrandr -q
Screen 0: minimum 2560 x 1024, current 2560 x 1024, maximum 2560 x 1024
default connected 2560x1024+0+0 0mm x 0mm
   2560x1024      50.0*

I think this may be because I'm using the xorg.conf files as generated
by the nvidia-settings tool. I'll try starting X without an xorg.conf
file to see if this has any effect.

Thanks,
Mike
