My notebook has an APU and discrete GPU.

aticonfig --lsa

* 0. 00:01.0 AMD Radeon HD 6620G

  1. 01:00.0 AMD Radeon 6600M and 6700M Series

 

aticonfig --pxl

PowerXpress: Discrete GPU is active (High-Performance mode).

 

aticonfig --lscc

Master adapter:  0. 00:01.0 AMD Radeon HD 6620G

    Candidates:  none

Master adapter:  1. 01:00.0 AMD Radeon 6600M and 6700M Series

aticonfig --lscs

    Candidate Combination:

    Master: 0:0:0

    Slave: 0:0:0

    CrossFire is disabled on current device

    CrossFire Diagnostics:

    CrossFire can work with P2P mapping through GART

However, when I run clinfo I get only one two devices: one GPU (the discrete GPU) and one CPU.

 

I tried configuring the xorg.conf using aticonfig --initial --adapter=all, but still no luck.
