The ubuntu forums link helped some. In /etc/kde4/kdm/kdmrc , I set: TerminateServer=true
That brought back the login screen when I log out. However, if I switch to the console (ctrl-alt-f1) and try to switch back (ctrl-alt-f7) then I get the blank, black screen again. Restarting kdm brings it back again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/773073 Title: kdm hangs upon logout -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
