disabling idle sleep timeouts

I left the server on a shelf for a bit and tried to connect to it remotely, I found it asleep.

so I turned off the only sleep time I could find:

sudo gconftool-2 \
 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults \
 /apps/gnome-power-manager/timeout/sleep_computer_battery --set --type integer 0

and restarted gdm

sudo /etc/init.d/gdm restart

hopefully the server doesn't go to sleep any longer.
