That's kind of the crux of it. X sessions tend to do things like run 3d screen
savers, periodically check cdrom drives for new disks, periodically wake up to
update load graphs or network graphs, etc.
Even login screens are getting fancier and even the regular non-3d screen
saver is a problem.
For a benchmark machine you really don't want to find out after you run your
benchmarks that there are mysterious spikes or dips and have to waste energy
tracking down where they come from.
I'm unclear why you would be running the enterprise management tools on
individual machines though. Isn't the point of enterprise management tools
that you can manage the whole enterprise? Ie, that they work remotely?
