I'm using Linux Mint and I was trying to enable GPU rendering, but I still have only CPU option in user preferences...
- Linux Mint 17.1 x64
- Radeon HD 7850
- Blender 2.75 rc2
- amd-catalyst 15.5
solved by myself

I have found solution to my problem. To enable openCl on Linux Mint 17.1 with ATI radeon video card just install ocl-icd-libopencl1 package for 64 bit system, or ocl-icd-libopencl1:i386 for 32 bit system. No need to run Blender as root or set up environment variable.

On Ubuntu open the Terminal and do:
sudo apt-get install ocl-icd-opencl-dev
then:
CYCLES_OPENCL_SPLIT_KERNEL_TEST=1 blender
