i want to star mining bitcoins, i'm getting a problem runing cgminer on my PC.
[root@unknown ~]# optirun cgminer -n
[2013-04-11 14:55:17] Error -1001: clGetPlatformsIDs failed (no OpenCL SDK installed?)
[2013-04-11 14:55:17] clDevicesNum returned error, no GPUs usable
[2013-04-11 14:55:17] 0 GPU devices max detected
i already installed cuda and opencl, but nothing has changed...
already tried other apps, and also compiled with opencl support.
I think this have something to do with hybrid graphics and bumblebee
[root@unknown ~]# pacman -Q cuda
[root@unknown ~]# pacman -Q | grep opencl
[root@unknown ~]# lspci | grep VGA

I had a similar issue. Downgrading opencl-nvidia to 313 worked for me.
