I'm running Ubuntu 12.04, 64 bit

I noticed that "compiz" was eating 40% of one of my CPUs and wanted to find its configuration. After not being able to find anything in the "Settings" with words compiz or similar (I'm used to 11.04 where I had 3 settings for fanciness of animations etc) I started googling. Most suggestions say to do this:

gconftool-2 --recursive-unset /apps/compiz

or

gconftool-2 --recursive-unset /apps/compiz-1

I did the -1 action and my Unity closed. Restarting the computer does not bring any window manager back up. I get desktop with 2 icons, and no window manager.

How can I solve this?

P.S
Shortcuts don't work. Alt-F2 does nothing, single tap on Alt, Ctrl, Super does nothing. To open a terminal I have to open a Desktop folder icon, then search for gnome-terminal in /usr/bin and open it that way. All windows that open up cannot be resized etc.
