Tim:
Oops! I neglected to mention that I use ctrl-alt-functionkey to switch
(then c-a-F7 to switch back).
Which isn't stopping X, just ignoring it for the while. X is still
running, even though you don't see it.
Then perhaps I'm confusing something here. In rl=5, top lists 'Xorg' -
which I took to be X windows. It was consistently at .3 - .7% of cpu
usage. In rl=3, it wasn't listed in top. So, am I confused?
I'm just looking to have every cpu cycle availible for the cruncher
client while I'm not using the machine.
