I'm trying to get my sony vaio laptop to display correctly on a projector. The laptop has a wide screen and normally X runs at 1200x800 while the projector has the usual 4:3 aspect ratio. I read the projector could do 1024x768 but I couldn't get it to do anything finer than 640x480. On the laptop I'm running compiz, with the nvidia driver. I booted the laptop with the projector plugged in and I did get X to display on the lcd, with no changes to the xorg.conf. Due to the difference in resolution between the laptop and the lcd, the xclock appeared about 1/4 screen on the projector, and a shell took up the whole screen (on the wall). I added Modes "640x480" in my xorg.conf to lower my laptop's resolution - didn't help. How do I set this up correctly? Do I have to configure dual head monitor? Does it depend on the projector? On the fact that the laptop is a sony? I have a major talk in less than 2 weeks and I have to give some live demos, so I'm in dire need for help. Thanks!
