How to Autostart Applications in Kubuntu

If you need or use a particular application every time you're on the computer, you can have the application autostart for you.
Instructions
Step
1
Open your Konsole, Terminal or Yakuake (refer to Tips for Yakuake Installation). The first thing we need to find is the location of the application. The command, whereis, will be used to do just that. Since I use the command line quite a bit, I will go with Yakuake. Type: whereis yakuake. The results will show you the location to the application and the manual. We only need the binary, /usr/bin/yakuake.
Step
2
Now that we have the location, we need to copy the binary to the Autostart folder; /home/user/.kde/Autostart. A regular user cannot manipulate the /usr folder or its contents. For this reason, we will use "sudo". Type the following command into Konsole, Terminal or Yakuake window: sudo cp /usr/bin/yakuake /home/user/.kde/Autostart/ . The last slash is important.
Step
3
We have now successfully copied the Yakuake binary to your Autostart folder. Reboot your computer, if you wish, to see the application start at login. You will see a popup window in the top left corner of your screen letting you know Yakuake has been started.
