No graphic drivers succeed to install in ubuntu 11.04

[LaPingvino]

Had this bug earlier. Two versions of Ubuntu ago it worked fine, then I tried Nouveau and got it all ****ed up, then got the proprietary drivers working again. Now doing a clean install (but with existing /home partition) and it refuses to install the graphic drivers...
