I recently reinstalled Ubuntu and I am unable to get my laptop to go beyond 640 by 800. This, obviously, hampers my ability to click the ok button in some areas. My hardware follows:

Gateway Mx3228
1 gig RAM
64 MB shared video
Display Unichrome S3G resolution maxed at 1280 by 768 in windows.

Since I am not in windows, I believe that my display is S3g. I know it is Unichrome.

Also, I may have already found the driver, but It will not allow me to copy the file into my USR folder. It says access denied. How can I grant it permission and edit my xorg.conf file to read the file?
