I actually want to change the default window position of gnome-terminal in my Ubuntu 12.04 system.

After some search, I found some one else use the command gnome-terminal --geometry=120x80+50+50 to set the default position.

And I actually don't know where to paste the command, so I pasted it to 'custome command' field of terminal's profile.

Now when I open one terminal, it just keep opening new ones and I have no way to stop it other than ctrl+C.

I even removed .gconf/gnome-termial/ folder and it didn't worked.

Can someone help me?
