OpenCL only works as root
No matter how I try to get OpenCL working (sgminer, cgminer, c programming examples, clinfo)
I only get a result when I run as root.
When I run clinfo not as root I get:
terminate called after throwing an instance of 'cl::Error'
what(): clGetPlatformIDs
Aborted (core dumped)
I am using the AMD opencl implementation, and the correct ICD file does exist under /etc/OpenCL/vendors. I have changing the permissions of various files with no success.
How can I get this to work without root access
make sure that your user is added to the video group:

- export OPENCL_VENDOR_PATH=/local/install/path/etc/vendors
- export LD_LIBRARY_PATH=/local/install/path/lib/x86_64:$LD_LIBRARY_PATH
