This will tell your system to boot into text mode.  If you want to switch while
you are running .. you can type "init 3" to go to text mode and "init 5" to go
to graphical mode.  This will need to be done as the root user.

The obligatory warning:-
Run level 3 may have different services loaded than run level 5. Study the output from "chkconfig --list" on your server to see what services are started in each run level.

E.g.:-
[root@zaphod ~]# chkconfig --list nfslock 0:off 1:off 2:off 3:on 4:on 5:on 6:off ypbind 0:off 1:off 2:off 3:off 4:off 5:off 6:off acpid 0:off 1:off 2:off 3:on 4:on 5:on 6:off diskdump 0:off 1:off 2:off 3:off 4:off 5:off 6:off webmin 0:off 1:off 2:on 3:on 4:off 5:on 6:off cqcs_acs 0:off 1:off 2:on 3:on 4:on 5:on 6:off ntpd 0:off 1:off 2:off 3:on 4:off 5:on 6:off xfs 0:off 1:off 2:on 3:on 4:on 5:on 6:off snmpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off sshd 0:off 1:off 2:on 3:on 4:on 5:on 6:off nscd 0:off 1:off 2:off 3:off 4:off 5:off 6:off syslog 0:off 1:off 2:on 3:on 4:on 5:on 6:off sysstat 0:off 1:on 2:on 3:on 4:on 5:on 6:off cpuspeed 0:off 1:on 2:on 3:on 4:on 5:on 6:off readahead 0:off 1:off 2:off 3:off 4:off 5:on 6:off smartd 0:off 1:off 2:on 3:on 4:on 5:on 6:off rpcsvcgssd 0:off 1:off 2:off 3:on 4:on 5:on 6:off radiusd 0:off 1:off 2:off 3:off 4:off 5:off 6:off mysqld 0:off 1:off 2:on 3:on 4:off 5:on 6:off
