works under root but not under normal users
i've installed nvidia package drivers... it works correctly... but under root only
when i want to log under other user i've a black screen and it fastly return to the loging window...
i can imagine it's a question of rights... but on which file?
i would like to ask here what to do to have 3d hardware acceleration under my linux under a single user session????
many thanx to all helpers...
