Description:
Luxmark segfaults on startup. It shows the GUI window, but crashes quickly. Running in GDB doesn't get me to the point of the crash, but running without shows briefly some info in the output console relating to my AMD GPU.
Selecting --mode=BENCHMARK_OCL_CPU gives an error:
RUNTIME ERROR: No OpenCL device selected or available

Selecting a different scene does not work because it can't find the render cfg files.
Selecting --mode=PAUSE allows me to interact with the GUI, and selecting the GPU benchmark crashes.

I am unable to get luxmark console output out of the GUI window, but I don't see an ERROR appearing there.

Additional info:
* luxmark 1.3.1-4
* Radeon GPU with Open Source driver stack (including opencl-mesa), and an Intel CPU.

Steps to reproduce:
Install luxmark, run luxmark.
This task depends upon

To be honest I would be _very_ surprised if it worked on you setup. Open source drivers still have a long way to go to be usable for OpenCL, so if you want to use GPU for OpenCL, you pretty much have to go for nVidia with binary drivers. And obviously the Intel CPU wont work without drivers, which can be found on AUR in the intel-opencl-runtime package.

Oh, and regarding the broken other scenes - it's an upstream issue, because the syntax for scenes changed some time ago, but some of the scenes have not been ported yet (and yet they are still accessible from the options).
