Ctrl+Alt+T doesn't open the Terminal, and I'm pretty sure it's got something to do with Compiz.
Compiz disabled the transparency on my launcher (using Ubuntu 12.04 LTS with Unity) and so I uninstalled it.
But after I uninstalled Compiz, my UI was messed up, so I reinstalled it. Now Ctrl+Alt+T doesn't open the Terminal.
System Settings >> Keyboard >> Shortcuts has the shortcut to terminal there, but it simply does not work.
What should I do?
