Well, i have to say sorry cause, i'm the one who started all of this. Actually i only wanted to sort the gl pb, cause i couldn' activate, but i solved from the normal user. Sorry about all of this, i don't use the root at all. :D
Sorry once again. Dono, but until now i wasn't using su, but wih it it is easyer. :D . Anyway, i'm still having problem installing some software, i can't compile berkeley db so without it i can't install kdevelop. i'm still trying.
