I've been all over these forums, and it appears others have had similar issue... but all the solutions they get do not appear to work for me.
So, here is the backstory. I'm using this guide:
http://www.distrogeeks.com/install-cgminer-latest-ubuntu/Running on Ubuntu
pickaxe@Pickaxe:~$ cat /proc/version
Linux version 3.5.0-17-generic (buildd@roseapple) (gcc version 4.7.2 (Ubuntu/Linaro 4.7.2-2ubuntu1) ) #28-Ubuntu SMP Tue Oct 9 19:32:08 UTC 2012
I have the 7950s installed
pickaxe@Pickaxe:~$ sudo aticonfig --lsa
* 0. 01:00.0 AMD Radeon HD 7900 Series
1. 02:00.0 AMD Radeon HD 7900 Series
2. 05:00.0 AMD Radeon HD 7900 Series
They appear to be configured correctly.
pickaxe@Pickaxe:~$ sudo aticonfig --adapter=all --initial

However...
pickaxe@Pickaxe:~$ export DISPLAY=:0
pickaxe@Pickaxe:~$ xhost +

pickaxe@Pickaxe:~$ sudo aticonfig --adapter=all --odgt

And cgminer does not see any of them.
pickaxe@Pickaxe:~$ cgminer -n

Where did I go wrong?
Help would be appreciated.
