Easiest way to do this is to start an xterm, su to root, and type
"redhat-config-services &". That will give you a GUI to select the
services you wish to run. Depending on how much you selected when
installing, it could be quite a bit.

Runlevel 3 is the Red Hat standard for booting into command-line mode,
and runlevel 5 is the standard graphical login level.

The only critical services controlled by this are network, syslog,
xinetd, and nfslock (if you are using NFS). Do not disable those unless
you know what you're doing it for. iptables is the firewall control
(only disable if you are in a very well protected network).

Most everything else can be turned off.

128 MB RAM is marginal for using KDE or Gnome on RH9. You can do it
(that's all I had on my first Linux box) but it's a pig.

You've got almost 70 MB in swap - over 30% of your total process
memory. BTW - what kind of computer is it? If it's not some oddball
hardware, your best solution is some RAM. 256 MB is enough to make X happy.

The difference between 'ps -al' and 'ps -Al' (note the uppercase A) is
that ps -Al shows all of the processes running on the computer - whereas
ps -al only shows the processes running on the terminal that ran the
command.
