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.

Open up a terminal by browsing to /usr/share/applicationsin your file manager and double-clicking gnome-terminal.desktop. Now, run unity --reset.

  • Thank you! After running that command my terminal froze, but resetting the desktop via Alt+Prnt+k finalized this.

    The --reset switch is now depreciated, at least in 14.04. Is there an alternative please?

I had the similar problem in 14.10 . I solved it by deleting my ~/.config/dconf/user and ~/.cache/compizconfig-1. It worked out for me, in case if it doesn't work out for you try installing a different window manager(in my case I had cinnamon and was able to use it smoothly even when I had problems in default window manager).
