KDE Session Management and Autostarting

First time I added an application to “~/home/.kde/Autostart” it comes up with another (+1) instance every relogin to X session. This was because of the settings in ksession manager.

Go to “Start > System Settings > Advanced >Session Manager”. There are two options how to fix this issue.

1. On Login:
   enable “Restore manually saved session”
2. Advanced:
   enter a comma separated list of executables to be excluded from session management

This settings force the applications added to “~/home/.kde/Autostart” to startup with only one instance every logon to X session.
