I was able to get my plasma-desktop starting up properly again by going into System Settings/Advanced/Autostart. The entry for plasma-desktop was present but not enabled. All I had to do was tick the box.
So in my case at least, the bug is that something unticked that box. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kde-workspace in Ubuntu. https://bugs.launchpad.net/bugs/976397 Title: in Kubuntu 12.04, plasma-desktop does not start in the KDE session To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kde-workspace/+bug/976397/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
