I did the sudo aticonfig -f --adapter=all --initial and rebooted, I also deleted the .bin file in cgminer's directory.

CGminer gave an error about the number of devices not matching. It saw three devices, but OpenCL was only seeing one?
...

opencl has nothing to do with xorg I'm afraid, but what you need before starting cgminer is:

Code:

export DISPLAY=:0

I'm not running as root. DISPLAY is already set. And I'm not using SSH, I'm on the local console.

I just suffered from the same problem. If your DISPLAY is set to ":0.0", clinfo only finds one card!!! This is dumb.

You can correct it by setting it to ":0" as suggested above.

I found the solution haphazardly from here: http://devgurus.amd.com/thread/140667

It's not dumb - it's the way Xorg works. Before I was using CGMiner, I had 3 instances of phoenix on :0.0 :0.1 and :0.2 . That's how you specify cards.
