Ok, its seems that my problem is with KDM. Neither Etienne or DarK SouL solution works for me. But when KDM is disabled, I can login/logout as many times as I want.
To reproduce: 1- Boot in recovery mode and "sudo mv /etc/init.d/kdm /kdm" 2- Reboot, login as a normal user and "startx" 3- Logout from KDE 4- "startx" 5- Repeat from 3- as many times as you whant. I can reproduce this with "ati" and "fglrx" driver. I'm moving to bug #211318 (seems to be the correct for me) -- logout hang xserver with ati open drivers https://bugs.launchpad.net/bugs/119635 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
