Hello, I am trying to start a very small mining rig (HD 6950). I am using kubuntu 15.10 AMD driver 15.12 Open CL libraries 3.0 When I start cgminer -n it tells me that there is not GPU available (yes I added --enable-opencl in the configure commande line) When I ask aticonfig to tell me how many GPU available it tells me 1. So I don't know where to start to solve my issue. Thank you for your help
Hi Jolan, You are right. clinfo can find the CPU but not the GPU... I tried to use an older version of AMD SDK. No luck. I will try to install an older release of kubuntu to use an older version of the catalyst driver. Also, when I try clinfo or HelloWorld from the AMDSDK V3 I get a segmentation fault ... This doesn't sounds good ... Thank you.
I am totally stuck with this issue. I tried few version of the driver, few version of kubuntu ... nothing works. I also tried the script sgfxi ... No luck. I have installed windows 7 and did an autodetection of the hardware to install the right driver ... opencl is working fine ... So I don't know where is the problem, but one thing is sure, the problem is not the hardware. I will try centos 7 ...
Look in /etc/OpenCL/vendors and see if there is an amd.icd or amdocl64.icd file in there. If not, you probably need to create it. sudo sh -c 'echo "libamdocl64.so" > /etc/OpenCL/vendors/amd.icd'
Thank you Jolan, In the /etc/OpenCL/vendors/ I have 2 files : - amdocl32.icd -> libamdocl32.so - amdocl64.icd -> libamdocl64.so
I solved my problem ... had to install fglrx-updates after the installation of catalyst ... I don't understand why but I had to... Thank you for your help Jolan.
Now when I mine ... Xorg comes to 100% of CPU and the display crash ... Nothing relevant in Xorg.0.log. latest cgminer / ubuntu 15.10 . I guess the mix of fglrx-update and the catalyst software does not mix well... Any hint on this ?
I would also like to note that I am having a very similar problem using my AMD Radeon HD 4830 but I cannot install fglrx since Ubuntu 16.04 doesn't support installing fglrx at all. I will be back from my vacation in a few days and then I will elaborate more.. Until then, any help would be useful...
