@Maarten: I don't think I did anything other than reinstall unity-2d- default-settings. As a matter of fact, I think I did unity-qt-default- settings on the first machine. Both came up back normally, with both showing Unity 2d in the chooser, and I checked version numbers and they are current to what is showing in Launchpad.
@Florian: I used update manager, and it gave me a partial upgrade, which I performed. When I logged off and back on, I got desktop only. That's when I restarted, went to recovery console and did what I stated above. Requested files attached. ** Attachment added: "2dsettings.txt" https://bugs.launchpad.net/ubuntu/+source/unity-2d/+bug/705035/+attachment/1799823/+files/2dsettings.txt -- 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
