The chkconfig it's a tool to edit the runlevels, or in other words, to choose which services are automatically initiated when the computer starts.

Unfortunately the chkconfig it's not available in Kubuntu so, if you come from SuSE, don't look for it.
There's however an excellent substitute and it's sysv-rc-conf

To get it just do:

$ sudo apt-get install sysv-rc-conf

Then follow the manual:

man sysv-rc-conf
