Changing Startup Options
 

I have Red Hat 8 installed on my computer. The way I installed the OS was to boot to KDE, however now I don't want to boot into a windowing system, I want to preserve my limited memory. How do I change the default boot and is it still possible to start the windowing system at my descretion. Thanks for any help.

It is very easy to change what 'runlevel' you boot into.

Edit /etc/inittab so that the default runlevel is 3 instead of 5.

See the section "Determining The Default Boot runlevel" in the HOWTO The Linux Boot Process.

You want to change this:

id:5:initdefault: # Console GUI Mode

To this:

id:3:initdefault: # Console Text Mode

Then, to start X when you want, use the command 'startx':

user@linux:~$ startx
