laptop display to a projector

I gave a presentation this afternoon but was unable to get the gnome GUI to
display at any resolution I tried (1024x768, 800x600, 1280x800). Actually,
1280x800 did display at first but poorly. I was using my HP dv6275us laptop
running Ubuntu 6.10. This machine has an Nvidia 7400 card (128mb on board)
and the linux restricted drivers installed (not the nvidia binary). During
boot up most text screens and the splash screen would display. In most
cases the gnome desktop displayed like a hash of bars and boxes with nothing
readable.

Afterward I came home and plugged a reasonably nice monitor into the vga
port and got similar results.

I tried lsmod but didn't know what might be meaningful

Anyone have any good ideas. I am giving another presentation tonight. My
current thought are to port the presentation to Microsoft Office and use
Windows to try driving the projector (yuck).
