[PlanetCCRMA] FC2.1vP9 - jackstart just quits...

[R Parker]

Hi Mark,

A setup strategy that might be interesting for you
would be to use run levels. Run level 5 is default.
Run level 3 is available and can be customized to suit
your needs.

To switch run levels:
*logout of current session, probably runlevel 5
*Alt+F1
*telinit 3
*startx

To configure a run level:
System Settings : Server Settings : Services

You can configure any of the run levels within the
Services interface so be sure to open the one you want
to work on. Maybe that's enough info to get you
started. Otherwise poke around the online Redhat
documentation.
