Well, all those who love to use terminal or are in need of using terminal frequently, would know about Guake, which bring terminal with a touch of a button. But the thing is after it is installed, it does not start up automatically during system startup. It was a bit frustrating for me, I searched Google for a few minutes and hit upon the answer,
type this is terminal
sudo cp /usr/share/applications/guake.desktop /etc/xdg/autostart/
This will make Guake start automagically during system startup. I read this here.
After going thru the menus a little i found this can be done without going to terminal too in Ubuntu Karmic, don’t know abt the rest.
Goto System -> Preferences -> Startup Applications.
The Startup Application Preferences window opens. In the Startup Programs tab click on Edit Button. Give a Name for the Application in the Name field, and then type “guake” without quotes in the command field and click Save. Then close the Startup Application Preferences window and restat the machine, now Guake should start automatically on login.
