Title: bfgminer - "Failed to load OpenCL library, no GPUs usable" Post by: snowweb on August 12, 2013, 02:39:37 PM That's the message I get when starting bfgminer. It then goes on to load and run but using only CPU's.
I ran "bfgminer -D -T -d?" and this was the output: Code: $ bfgminer -D -T -d? I'm running Ubuntu 12.04LTS with 3.2.0-38-generic-pae #61-Ubuntu SMP Tue Feb 19 12:39:51 UTC 2013 i686 i686 i386 GNU/Linux Hardware is an Acer Aspire 4752G laptop with Nividia GEforce GT 630M graphics card. bfgminer version is 3.1.4 Any suggestions please?

You are probably using something like Noveau which hasn't support for OpenCL.

I'm certainly attempting to use the the proprietory Nvidia driver, however, I'm finding it difficult to tell whether I've succeeded. I've removed bumblebee as I gather that forces the integrated graphics and I have installed the appropriate graphics driver from Geforce. Although, when doing that, it complained that the existing hardware did not match the driver, but unless the machine is mislabled, it was. The machine is clearly labeled as having Nvidia GEForce 630M card and the driver I installed explicitly stated that that support for that exact model was included, then at runtime it questions it but allows you to continue install, which I did. I ran nvidia-xconfig and restarted X, but still no joy. I also installed opencl sdk but then removed it since it is apparently for AMD architecture which I don't think mine is. I also installed nvidia-cuda support, the equivalent of opencl but for nvidia devices. Now, not only am I left with a screen resolution of 640 x 480, I'm out of ideas how to proceed. Any help much appreciated! Thanks. |
