Ubuntu – How to reset the Unity configuration

unity

I've been messing around with Unity and broke something, how do I "start over"?

The following command does not work on newer distributions (as the reply is ERROR: the reset option is now deprecated).

For 12.04 and older

The simplest way is to hit "open a Terminal" or hit Alt-F2 and run the command:

unity --reset

plus one for me. But with this, I got it:

sudo apt-get update
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install unity

Seems to wired, and I think it was more luck than brain, but it worked for me.

check if ubuntu unity plugin enabled in ccsm

and see if this work
