Hi,

I have a Linux system with onboard video (which is used for output) and I added an extra nvidia card (GeForce 7300GS).
It is a debian system and i installed all neccessary packages to be able to run poclbm.py
The user with which I run it has full access rights to /dev/nvidiactl and /dev/nvidia0
But if I then run it, I get:

bitcoin@weerstationserver:~/poclbm$ python poclbm.py
Traceback (most recent call last):
  File "poclbm.py", line 26, in
    platforms = cl.get_platforms()
pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error code
