Thanks for the additional information Thomas, /tmp/unity-support-test.0 isn't relevant at all in that case.
Ok, so unity-2d receives a BadWindow error in your configuration and it seems it's not linked at all at the user data in their home directory. I'm pretty sure unity-2d should crash, do you have nothing in /var/crash/*unity*2d* ? If so, can you please apport-collect the crash and attach it to this bug? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993694 Title: unity-2d does not start if user has logged in on unity To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-2d/+bug/993694/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
