It seems like one potential problem is that the gconf keys setup by unity-2d-default-settings did not get set correctly during the upgrade for some reason. The postinst of this package is supposed to trigger updating of the gconf keys, so not sure why this wouldn't have worked. Couple of things to try as workarounds:
1) from terminal run the following: sudo update-gconf-defaults --source /usr/share/gconf/unity-2d/mandatory --destination /var/lib/gconf/unity-2d.mandatory --no-signal sudo update-gconf-defaults --source /usr/share/gconf/unity-2d/default --destination /var/lib/gconf/unity-2d.default --no-signal 2) logout and log back in using Unity 2D session If you still don't get correct panel, launcher, etc, then try the following while logged into the Unity 2D session: 1) run the following commands from a terminal gconftool-2 --set /desktop/gnome/session/required_components_list --type=list --list-type=string [windowmanager,panel,launcher,places,filemanager] gconftool-2 --set /desktop/gnome/session/required_components/windowmanager --type=string metacity gconftool-2 --set /desktop/gnome/session/required_components/panel --type=string unity-2d-panel gconftool-2 --set /desktop/gnome/session/required_components/launcher --type=string unity-2d-launcher gconftool-2 --set /desktop/gnome/session/required_components/places --type=string unity-2d-places gconftool-2 --set /desktop/gnome/session/required_components/filemanager --type=string nautilus 2) log out and back in using Unity 2D session -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/705035 Title: Unity Qt session broken after an update -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
