I was in the process of adding Gnome Tweak to my system and my computer locked up (first time ever in Linux, BTW). Now when I log in using Unity 3d, I have no docking bar. I can't use Gnome either. I can only log in using the Unity 2d mode. Anyone have idea how to get this straightened out? I have used computers for a fairly long time. I'm very comfortable with command line.
Any help would be appreciated!
