That didn't work for me.

When I use -configure to generate a conf file the Monitor specs seem to 
fit my monitor but the monitor won't use it.

Looking at /var/log/Xorg.0.log I can see that it tries all the modes 
and says this for each of them:

(II) NV(0): Mode "1024x768" is larger than BIOS programmed panel size 
of 1 x 1. Removing.
(II) NV(0): Not using default mode "1024x768" (unknown reason)
(II) NV(0): Not using default mode "512X384" (bad mode 
clock/interlace/doublescan)

....

(EE) Screen(s) found, but none have a usable configuration.

Fatal server error:
no screens found


Funnily enough, when I passed Xorg -config a non-existent config file 
name (by accident) it displayed the black and grey grid with the X in 
the middle.
