This bug is also reported on ATI Bugzilla : http://ati.cchtml.com/show_bug.cgi?id=239
It seems that there is a workaround : - For GDM : add AlwaysRestartServer=true in section [daemon] of /etc/gdm/gdm.conf-custom (it works for me) - For KDM : Add TerminateServer=true in section [X-:*-Core] of /etc/kde3/kdm/kdmrc (i'm not sure of the config file, i don't use KDE) -- Hardlocks w/ latest FGLRX https://launchpad.net/bugs/50535 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
