The *nix system is layered:
console or text apps
frame-buffer apps
[add X server]
x based apps
[add tool kits like gtk or qt or kde...]
gnome,kde, and other apps

if you remove X and various higher bits, you still have fb and console
apps. Its always good to know the 'commandline' when X has trouble.

then there is session management and interoperability, a display
manager, and window management:
'gnome' include: X, a display manager(gdm), a window manager(metacity),
a session manager and various toolbars and inter-related programs and
tools.

you can remove or replace various bits:
you can:
replace the WM (metacity) with a lighter one like twm
change the desktop environment(remove gnome and replace it with xfce)
disable or remove the display manager(gdm) and use startx (at the
console)

Also, desktop environments also run various memory intensive ´services'
that add to the overall memory footprint. So use 'ps -A f' to see all
those beasties.
