Out of curiosity, I did some (very rudimentary) tests a while ago were
I logged on remotely and measured loads on the system in various
states. One of the things I noticed was when the system was just
sitting at the (default) gdm login screen it used almost no more
CPU/Memory power than if I was in RL 3.
It was a different story once X started and a lot of crap started
chewing resources. Now if it's something I can do in text mode I just
Ctrl+Atl+F1 and log in on a text window, but the graphical display is
there if I need it (seemingly) without the overhead. Also noticed
that it unloaded everything when I logged out and went back to the
login screen. Was just wondering if there is another reason to not
leave it on the login screen or if it's just a hangup from the old
days?
