Interestingly, a similar bug was opened in 2006: Bug #38915 These bugs may be related, since people are also adding recent reports to that bug.
As a workaround, a suggestion posted in Bug #38915 seems to work for me: In the [X-:*-Core] section of /etc/kde3/kdm/kdmrc add the following line: TerminateServer=true -- [hardy] No logout possible in KDE4 https://bugs.launchpad.net/bugs/198220 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
