Linux Headless Issues

[lordneon]

Hi All,

I am having issues with a box running headless, as soon as I unplug the monitor the speed drops drastically, I am guessing this is an OS problem more than an oclHashcat problem?

Running driver:
[ 1.895598] [fglrx] module loaded - fglrx 14.30.4 [Sep 15 2014] with 3 minors
