Today I tried to change the alt+tab behavior of my Ubuntu because I did not like the grouped layout. I tried two shell scripts I found in a git gist. My problem is that since I used those scripts the behavior of Dash changed: when a program tries to notify me Dash appears for me (it is on auto-hide) and the application icon shakes for 5 seconds and it is often followed by the freezing of that application. Before I tampered with the settings it was shaking for only half a second and there were no freezing. How can I revert to the default settings?
unity --reset but I received error messages (complaining about the lack of opengl and ending in a Segmentation Fault). I tried removing and reinstalling Unity and Compiz:
apt-get remove unity --purge apt-get remove compiz --purge apt-get install unity apt-get install compiz
but nothing changed. How can I reset to my previous state (before running the scripts)? Some of my apps are freezing ever since I ran them although I reverted the changes in the shell scripts.
