I don't know if this will help or not, but last week I had the same problem
with my Slackware/Toshiba laptop. The problem there was easy enough to avoid,
if I followed the correct steps: Before connecting the laptop to the
projector, boot it to X. /Do not/ connect the laptop before you have your X DM
up (KDM/GDM/XDM)
Apparently, my problem is/was a hardware/software problem, in that the
laptop's circuitry checks whether the display is connected or not on power up,
and (if connected) it will /disconnect/ the LCD. Since our projector didn't
provide a DCC signal, and the LCD wasn't electrically active, X defaulted to
640x480 resolution.
If I didn't connect the projector before I powered on, the LCD worked, and X
detected it as 1024x768. Connecting the projector then defaulted the feed to
the same resolution, and the projector showed 1024x768
This might not be the same as the problem under discussion. However, since
laptops frequently work in similar manners, it might provide some clue as to
how to get the projector to work properly with a Linux laptop.
One further thought; Since I didn't know this at the time, I was left with a
presentation that I had to show in a 1024x768 'virtual' screen on a 640x480
real screen. I used xrandr to set my virtual screen size back down to 640x480,
and I did the presentation. xrandr might help you match your laptop resolution
to the projector resolution, if you can't get the projector to match the laptop.
