system sees 2 cards but cgminer only one

[antekh]

Hi, I have both HD 6870 and HD 7950
My system - Ubuntu 12.04
See both of them:

Code:

aticonfig --list-adapters
* 0. 01:00.0 AMD Radeon HD 6800 Series
  1. 02:00.0 AMD Radeon HD 7900 Series 

* - Default adapter

but cgminer only 1:

Code:

[2013-04-19 16:38:08] CL Platform 0 vendor: Advanced Micro Devices, Inc.                    
 [2013-04-19 16:38:08] CL Platform 0 name: AMD Accelerated Parallel Processing                    
 [2013-04-19 16:38:08] CL Platform 0 version: OpenCL 1.2 AMD-APP (1016.4)                    
 [2013-04-19 16:38:08] Platform 0 devices: 1                    
 [2013-04-19 16:38:08] 	0	Barts                    
 [2013-04-19 16:38:08] 1 GPU devices max detected

What might be going on here?

Sorry to double post but I have found a solution:

Code:

aticonfig --adapter=all -f --initial[code]
After that system needs to be rebooted and cgminer picked up second card.
