I just installed Ubuntu on my Toshiba Portege 3500. I can't get it to display at more than 800x600, which sucks because in Windows on the same machine I can get 1024x768. I found a webpage that said my CyberBlade video card works with xorg's trident driver, so I edited my xorg.conf file to use that one. Nothing changed. Am I missing some step required to update xorg? Oh, and I did restart the computer since I changed it, so it's not that.
