Is it possible to un-install a graphics card driver?
 

I recently installed one, booted to windows, and back linux just now, and the graphics are fuzzy'ish....and for sum reason my screen size is huge and i cant seem to get it smaller.
Is it because of the driver..?

Im trying to resize it but the screen resize and rotate progrom wont let me change anything.
Im still on the same resolution, but for some reason everything is like 5x its normal size.
How can i get it back??

It would probably be useful to know what video card you have, and what graphics card driver you installed.
