Ok, here is a definitive workaround for this problem, i think this work for everybody :)
As said by "lvscar" for GDM, we must impose KDM to restart Xorg on relogin/switch to terminal instead to simply reset it. In Kubuntu by default, xorg is resetted, allowing a more rapid kdm reload, but by now this cause a problem using fglrx driver (i'm not sure if this is a problem of Xorg or of fglrx driver). To do this, simply edit the file /etc/kde3/kdm/kdmrc as root, and find the commented line: #TerminateServer=true you must uncomment it, so it will be: TerminateServer=true Save the file and reboot (I advise to reboot the pc, not only the session, for security...). For me it works perfectly (I've seen that "UseInternalAGPGART" "no" doesn't work for everyone).
