"Both of these features were present in KDE 3. Autostart
programs could be dropped into the ~/.kde/share/autostart
directory, and automated programs (cron jobs) could be created
through a standalone application called KCron.
"With KDE 4, Autostart and KCron are now both integrated into
System Settings. To start either one, simply click on the K menu
and then click System Settings. Next, click the "advanced" tab.
Under the Advanced User Settings section, you should see Autostart,
and under the System section, make sure that you see Task
Scheduler. On my Kubuntu system, Task Scheduler was not installed,
so I had to start kpackagekit and install the kcron package."
