This happened to me after a fresh install of beta2. Everything was well and good (used for days with Unity) before I installed xfce4. I used xfce4 for a few days, then tried to switch back. I couldn't select the Unity WM option (unclickable) in lightdm. So I completely uninstalled xfce4 and now lightdm doesn't show any options (should go automatically to Unity) but just loops back to itself.
I checked ~/.dmrc and it says session=xfce which I change to ubuntu and reloading lightdm, if I try to login again it rewrites ~/.dmrc back to xfce and I'm bounced back to the login screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/952149 Title: lightdm doesn't load unity sessions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/952149/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
