/etc/gdm/gdm.conf:
AutomaticLoginEnable=true
AutomaticLogin=mozqa
Make sure to restart gdm to pick up the changes:
sudo /etc/init.d/gdm restart
 
replace random with urandom
cd /dev
rm random; mknod random c 1 9
 
=== Throttling ===
Install cpufrequtils (002-2)
Check cpufreq-info for the name of the CPUs on the given box, then run these commands with the appropriate numbers:
cpufreq-set -c 0 -g userspace
cpufreq-set -c 1 -g userspace
cpufreq-set -c 0 -f 1000
cpufreq-set -c 1 -f 1000
Check cpufreq-info again for correct installation, can be confirmed by running:
cat /dev/zero > /dev/null &
Watch in top that the %cpu is topped out, check cpufreq-set to see that it isn't using all the cpu's Mhz.  Make sure that you kill this process after you've done this check.
