Well that didn't work. I installed EnvyNG for Ubuntu 8.04 and automatic detection didn't work so I tried manual and it installed and rebooted. Then I tried testing all the ATI Radeon cards because my card wasn't there and none worked. So I booted with the default vesa driver and found I only had 640x480 screen resolution, so I unistalled envy from the package manager but I'm still in 640x480 mode. Thanks anyway.
Edit: ok, I booted into recovery mode and choose 'Try to fix xserver' and that got my screen resolutions back.
