I have Linux Mint 13 with Cinnamon installed, but I can't open a terminal using right click nor using CtlrAltt this is just an issue with Cinnamon, why is that happening?
gnome terminal wasn't installed, i don't know if anyone is going to fix that, but i solved it by
sudo apt-get install gnome-terminal
and i posted my solution on launchpad, I'm not going to delete this question. maybe someone else faces this problem.
