I want to setup my Ubuntu 12.04 with OpenCL(Open Computing Language) support for i7 2600k and Radeon HD5870.

My Monitor is connected to the integrated Graphics of the i7. Intel OpenCL SDK is installed and working. Iteration of avaliable OpenCL devices shows 2 entries for Intel.

As recommended I installed AMD APP SDK 2.6 first and then the fglrx driver.

I installed fglrx from Ubuntu repositories. This works fine till here.

When I run

aticonfig --inital -f  

and restart the system I get into trouble.

Xorg starts only in low-graphics mode.

Is there a way to get the Radeon to work in a hybrid configuration

or to use the Radeon as an OpenCL only device?
