How To Reset Unity in Ubuntu-11.10 .

Leave a Comment
Today I installed Ubuntu-11.10 and I was playing around with Ubuntu, trying different themes, different engines, different window managers,file-managers(dolphin-one of my favorite), etc.
After installing CompizFusion, I started playing with themes and bymistakly, I removed my unity-panel.
So there was no shortcut to run app with "Alt+f2" key.
Thank god,I had installed Awn-dock , then I started firefox and googled about it and finally I did reset my unity2d settings to default.

Reset Unity
If you want to reset Unity (this will only reset the Unity settings in CompizConfig Settings Manager and leave the other CCSM settings intact), open a terminal (or press ALT + F2) and enter:
$ unity --reset
Reset Unity Launcher icons
$ unity --reset-icons
