It seems the problem is the dpm clock control for the primary video card. Setting power_dpm_force_performance_level to manual and then setting pp_dpm_sclk has no effect (it stays at 0).

I think something with Xorg may be interfering with the clock settings, so I'm going to try running X off the on-board video.

So far trying to run the iGPU along with amdgpu-pro is just as problematic as it was with fglrx. With the iGPU enabled and a Rx 470 and R9 380 plugged in, opencl crashes.

Code:

$ /opt/amdgpu-pro/bin/clinfo
Segmentation fault (core dumped)

try sudo command ,i think it will work

Thanks! That did it, and reminded me about the video group requirement from the driver install directions. I added my mining userid to the video group, and now OpenCL is working. I've left dpm_force_performance to auto for now, as the driver bumps both cards to dpm7 once they start mining. I tried manual to test things out, and for some reason it was only working for mlck. When I 'echo 7 > pp_dpm_sclk' it stayed at 0.
