I am really frustrated with BOINC on a Linux/ubuntu machine together with an ASUS GeForce GTX 970 GPU. I have never seen a weirder installation procedure. I was used to work with AIX and Solaris some decades ago. I had a few good XEON and i7 processors and boards available and I thought: Why not dedicating them to BOINC. And to add some juice to the task, I bought a brand new GTX 970 to speed things a little bit up. I decided to install ubuntu 14.04, because it is a long term stable version. There will be error fixing until 2018. On the other hand I would not like to 'waste' a valuable version of Windows of the ones I own. I needed something for free. Installation was easy. Write the ubuntu iso-distribution-file on a DVD and boot from it. There are a few pretty easy questions and after 10 min the system comes up with the standard graphical interface. A lot faster than Windows. The installation of BOINC was not that easy. I had to become familiar with the apt-get and aptitude routines. They were not in existence, when I worked the last time on a unix machine 22 years ago. After 30 min of reading posts in several forums I worked it out and the BOINC-Manager as well as BOINC-Client were running. But then the nightmare had just begun. Installing graphics on linux is unbelievable complicated and confusing. Just the opposite of Windows. Just adding the card in addition to the VGA mainboard graphics will crush the system. It always comes up with lowres graphics and all choices in the following menus are crap. You end in a shell and that's it. You have to install the driver for the card first. And here the horror begins. aptitude gives you a mega choice of drivers. Which one? Ok - linux x86-64 seems the right one. The 352 - which should be the best one in the moment - works with my ubuntu. After several hours of trial and error the card works. But BOINC does not recognize it <grrr> So deinstallation of BOINC with purge and reinstallation. But again no recognition of the GPU. Then I tried the installation of the CUDA drivers. 1.2GB is quite a lot for a package. But again - nothing. Then I read here in the forum that boinc-client-opencl should work. But again nothing. The command is not recognized. I am that new to Linux/ubuntu, that I am not able to look at error or configuration files. Is somebody out there who could help a novice in linux/ubuntu? Tell me step by step, how I set up such a 'standard system'? There are Petaflops out there waiting for a simple BOINC-GPU installation. If the community is able to formulate a standard procedure for dummies, then science will prosper a lot. Kind Regards, Horst Kind Regards, Horst ID: 65547 ·  |

Have you read the two excellent posts "When requesting help..." "Debian/Ubuntu/Mint/Derivatives - GPU recognition fixes" in this forum? They should help. ID: 65550 · |

I tried all the hints from the two mentioned articles (e.g. sleep, xhost, reconfigure boinc as last to start) but nothing changed. I even specified the nvidia GPU in the config file. But this command is ignored. Here are the first lines of the startup log. As I said before I am running ubuntu 14.04.3 with all updates so far. I installed the nvidia 352 driver with the aptitude command. Mo 23 Nov 2015 14:25:33 CET | | Starting BOINC client version 7.2.42 for x86_64-pc-linux-gnu What can I do else? Deinstall the nvidia driver and use another one? Perhaps from the nvidia homepage? But which one to use? boinc-client is 7.2.42 (quite an old one in comparison to the windows versions). Shall I go for much older nvidia drivers? Kind Regards, Horst ID: 65581 · |

No, it is not. I had to move to a different machine and have the same problems. Kind Regards, Horst ID: 65782 · |

In the meantime I found out, that the GPU on this machine was broken. I come back again later, when I got a new one. Kind Regards, Horst ID: 65783 · |

When you get the new one and if it's an NVIDIA then try installing nvidia-modprobe and/or nvidia-uvm packages if they are available for the driver version you have installed. ID: 65810 · |
