Ubuntu 12.04 Headless cgminer installation- "All devices disabled, cannot mine!"

Hi! I am having some problems with my ubuntu 12.04 LTS x86_64 and ATI Radeon 6990 mining rig.

I was able to complete the installation last night and everything was working correctly when I had the monitor connected to the system.

But now that I have moved the system to a more permanent location (headless - no monitor) I cannot get cgminer to start!

AMD Driver 13.1 x86_64
AMD-APP-SDK v2.8
cgminer 3.0.0

In it's now headless form aticonfig shows both of the GPUs:
sudo aticonfig --lsa * 0. 03:00.0 AMD Radeon HD 6900 Series 1. 04:00.0 AMD Radeon HD 6900 Series * - Default adapter

Script that starts cgminer:

Code:

#!/bin/bash

export DISPLAY=:0
export GPU_USE_SYNC_OBJECTS=1

cd /home//cgminer

./cgminer -o http:// -u -p -v 4 -g 1 -I 9 -w 256 --gpu-fan 75 --gpu-memclock 850 --gpu-engine 950

That is the same script I was able to use successfully when I had the monitor attached.

I have also tried inserting 'xhost+' into the script but that doesn't work either.

Has anyone run into this before?

My apologies for not posting in troubleshooting but I am still a noob

Thanks!
