I tried in a previous installation to use only MATE and remove Unity, uninstalling all unity-related packages from Ubuntu 14.04.
However, it happens I would probably need Unity to work with a DisplayLink screen (that connects fine on Unity but not on MATE). But, even after a complete reinstall of Ubuntu, I still have my Unity desktop broken. No side or top panels, and thus it's very very hard to start up any application to try to troubleshoot stuff.
I've seen similar posts, mostly pointing to some sort of
unity --reset command, but currently this only yields a message saying it's deprecated. How can I safely reset the Unity desktop while not touching MATE 1.8.1?
