Ctrl + Alt Workspace Switching Not Working

I removed Ubuntu 12.10 to try Fedora, I didn't like it as much and I put Ubuntu 12.10 back on my Lenovo T61 after I re-installed I did the updates and such.

However, I program and I use the keys Ctrl + Alt to see all my work spaces and switch to the one I want.

It is fast and I can edit my code in one window and execute it in another, when I press Ctrl + Alt it does nothing now I tried a bunch of stuff and restarted a bunch and still it won't work.

The only way I can switch work spaces is by clicking the work space switcher button in the sidebar and this is very obnoxious.

Please help.
