Ubuntu – How to remove Compiz

unity

I'd like some help to fix another unity issue.
After last update, my system broke.
For example, when I execute a 'ls' command, the screen breaks and does not show anything. Sometimes, just the beggining is shown.

How can I fix it?

I don't want use another X, for now…

Thanks

Before removing Compiz you might wanto to try and reset it

1.Press Alt + ctrl + F1

2.Login using your username and password

3.Reset compiz by executing gconftool-2 --recursive-unset /apps/compiz-1

4.Reset unity , by executing unity --reset

5.Optionally you can reset launcher icons by executing unity --reset-icons

6.Press Alt + ctrl + F7 to get back to login screen. However I recommend a restart by executing sudo reboot. Let us know if it worked.

Cerdits to Web-E

To remove compiz and compiz packages type this in a terminal:

sudo apt-get purge compiz compiz-plugins-main-default libcompizconfig0

Warning: Removing compiz also removes the packages unity & ubuntu-desktop.

Warning: Removing libcompizconfig0 also removes ubuntu-tweak.

Thus you will lose the ability to log into the unity or unity-2d desktops.
