Select

In "Startup Applications Preferences" "Startup Programs" tab, select any
applications on the left you want to start at startup. In your case you will
need to click and browse to the application you want to run at startup.

You probably realise this, but in case not- the command you want to
add can be added in the same way as described below after you have
saved the string as a script with something like #!bin/bash as the
first line then the command on the second. Then of course chmod to
executable.

Already have it working and tested. Worked easy........

You can put your command in /etc/rc.d/rc.local. This file load after the
system completes its boot procedure.
