I have a fresh install of Mint 17 64 bit, with the 340.24 Nvidia driver. My GPU is a GTX-750ti. I have tried 3 different versions of BOINC (7.2.42, 7.0.65 and 7.4.12) but keep getting No Usable GPU detected. I have tried manually bouncing the client as well. This same system running Ubuntu 14.04 was working fine a few days ago. Mint 17 is based on Ubuntu 14.04 so I don't understand what's different that is preventing the GPU from being recognized. Any ideas? |

Check through Debian/Ubuntu/Mint/Derivatives - GPU recognition fixes first. |

Check through Debian/Ubuntu/Mint/Derivatives - GPU recognition fixes first. Thanks there was some useful info there. I set the debug flag and restarted. The error message now is: Fri 08 Aug 2014 12:15:02 PM MDT | | NVIDIA drivers present but no GPUs found The GPU is working fine, the NVIDIA utility sees it correctly. |

What if you wait for a couple more minutes after a reboot and then manually start the client? At times the x-server doesn't start until late and it is needed for the detection of the GPU. |

Nope, then my knowledge is spent. I hope a Linux guru trawls through in a bit to help you along further. |

I downloaded and manually installed the same version of the driver from NVIDIA and it is now working. I had previously used Driver Manager to get it from the xorg-edgers PPA. I had assumed the one from the ppa was identical to the one on the NVIDIA website, apparently it is not. |

Any ideas? Here's mine: Mint 17 64 bit doesn't recognize your GPU. Just like it said. |

Any ideas? Here's mine: Mint 17 64 bit doesn't recognize your GPU. Just like it said. What driver are you using? Restarting the client might help, there is a timing issue with BOINC starting before the driver loads. sudo /etc/init.d/boinc-client restart If you add this to the cc_config.xml file it will provide additional diagnostics. <coproc_debug>1</coproc_debug> |
