command linecompizshortcut-keys
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?
In gconf-editor set the key
/apps/compiz-1/plugins/gnomecompat/screen0/options/command_terminal
to gnome-terminal --maximize
I found it to be compiz doing the things - I did some customization and at first I wanted ctrl+alt to bring up my launcher - but setting this in compiz makes ctrl+alt+t bring up trash instead of terminal, I bound my commands otherwise and worked around the issue, but I'll leave this post open for future people with the same issue. Or maybe to get the problem solved, or at least an explanation to why it behaves at it does! Compiz seems buggy anyhow - lot of CPU usage etc. so I guess there's a good chance this is some compiz bug too.

You can click on the Shortcut combination showing in the System Settings -> Keyboard -> Shortcuts and reassign the key.
Hope this will help.
If you have
compizconfig-settings-managerinstalled, you can reset the profile by going to the preference section of the program and clicking on Reset to defaults button.
