I don't know what distro you're using so I may assume some things here....
linux-default will most likely be a kernel with framebuffer enabled... this allows you to have higher resolution texts in the console. linux-nonfb won't have this feature. You won't notice this because you're booting straight into GUI.
From KDE, you can go to a console prompt by pressing
Ctrl-Alt F2 to
F6... to return to your KDE desktop press
Alt-F7.
To start up without a GUI, edit your
/etc/inittab file and change these lines:
Code:
# Default runlevel. (Do not set to 0 or 6)
id:4:initdefault:
to
Code:
# Default runlevel. (Do not set to 0 or 6)
id:3:initdefault:
Hope this helps
