WARNING: boinc_get_opencl_ids failed with code -1 Error: Getting Platforms. (clGetPlatformsIDs) BOINC assigns slot on device #0. WARNING: BOINC failed to provide OpenCL device, using own enumeration abilities ERROR: OpenCL kernel/call 'clGetDeviceIDs (second call)' call failed (-32) in file ../../src/GPU_lock.cpp near line 1311. computer: 7748035 This Ubuntu 16.04 machine got a new nvidia driver (not that I requested such) replacing one that worked with... the above. The good one, 340.104, worked fine a long time. In about a day the bad one accumulated 248 error tasks. Erroring very quickly indeed. There are reports of opencl issues with the latest driver on backports (which means on 16.04 ). Well, ugh. Took me a whole day to notice. I hope the older driver still works, I switched to the older one. I won't restart seti on this machine till I will be where I can watch progress and can stop it if nvidia/opencl still broken. |

I switched to Noveau, the non-nvidia driver. Rebooted. dpkg -l |grep -i nvidia sudo apt purge (the stuff listed by the above) sudo bash cd /var/lib/boinc*/projects/seti* and rm *wisdom* *bin* exit (back to being me) Used 'additional drivers' panel to request 384.130 Rebooted Restarted seti. One gpu task seems to be running toward completion. There are a few more. Turned off getting new tasks while I wait to see how the opencl_nvidia_SoG tasks go. |

Looks as if GPU tasks completing ok now. I'll keep watching. |

Why not just go to Terminal and type sudo add-apt-repository ppa:graphics-drivers/ppa ( then enter), may ask for password, then sudo apt-get update ( then enter) This will get you 396 drivers |
