I have probably the same problem. It happens almost everytime I try to relog.
After first attempt to relog, desktop starts, but it is in some "safe" mode, becase there are no composite effects, and I cannot enable them. When I try to relog again, there is no kdm, only glib warning (on black screen). Switching to console is not succesfull. Strange is, that there is no problem after I I log in to virtual console (before logout), also restarting kdm using "service kdm stop" helps. kdm.log shows: (EE) intel(0): Couldn't create pixmap for fbcon -- Non-admin user logout fails on Lucid https://bugs.launchpad.net/bugs/569879 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase-workspace in ubuntu. -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
