This is a symptom of the compiz program not running for some reason, likely due to a local (user-specific) configuration issue.
We're going to need a littl e bit more information about your system configuration. Please open a terminal (or, if not possible, switch to an alternate VT using control-alt-F1) and enter the command apport-collect 1304568 which will collect local configuration information and attach it to this bug for further analysis. In addition, please attach the file $HOME/.cache/upstart/gnome-session- Unity.log to this bug. ** Changed in: unity (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1304568 Title: Upgrade 12.04 LTS to 14.04LTS Beta 2 lost panel & launch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1304568/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
