The bug also apeared to be fixed with this procedure : [code] Hang at logout
If you experience hangs when logging out (of X) it is probably due to the /etc/ati/authatieventsd.sh script looking for X authorisation files in the wrong place when it starts up. You can kill the hanging authatieventsd.sh processes from a console tty to allow the shutdown of the X server. This can be fixed permanently with: sudo mkdir -p /var/lib/xdm/authdir sudo ln -s /var/run/xauth /var/lib/xdm/authdir/authfiles [/code] took from http://wiki.cchtml.com/index.php/Ubuntu_Intrepid_Installation_Guide But then reappeared.
