This problem was solved by patching /etc/ati/authatieventsd.sh (package xorg-driver-fglrx) as described here : http://tsdgeos.blogspot.com/2008/04/fglrx-blocking-xorg-on-logout.html
« Patch /etc/ati/authatieventsd.sh being unproperly configured, you need to change XDM_AUTH_MASK=/var/lib/xdm/authdir/authfiles/A$1* to: XDM_AUTH_MASK=/var/run/xauth/A$1* » Thanks to Olivier for the solution. This now needs to be fixed in the xorg-driver-fglrx package. -- After upgrade Gutsy => Hardy, exiting X session hangs machine (fglrx) https://bugs.launchpad.net/bugs/224732 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
