Multiple X Screens, Toshiba TE2100 laptop

[shiftAU]

I've recently installed Mandrake 9.1 on my TE2100. I managed to install the nvidia drivers without too many issues, now everything runs on a single screen well. Unfortunately, when I try to set up multiple screens (an external CRT and the internal laptop display) the laptop display stays completely blank. X believes the display is there and in the correct location, I can open up applications on the screen if I set my DISPLAY=:0.1, but I just can't see anything.

I've attached the log file, and a copy of my XF86Config-4 is here. Any help would be great.

Cheers,
Chris.

For some reason the attachment was lost, here it is.

I've now tried twinview with the same results. The virtual desktop seems to be the appropriately large size, the workspace switcher shows up the new weird proportions for the large desktop, my mouse happily disappears off the edge of my CRT to what should be the LCD, but the LCD screen stays decidingly black.

Thoughts anyone?

Well, still no luck here. The verbose log doesn't seem to show up any problems either, i've attached it here. Is there any further debug info I can get somehow?
