Installed the latest (weekly lately) 64bit kernel on CPUid 5766757 Ubuntu 14.04. Did the sequence that has worked for several months after getting a kernel update: sudo apt-get purge 'nvidia*' sudo shutdown -h now reboot.... Use settings additional drivers to get nvidia sudo shutdown -h now reboot... sudo apt-get install nvidia-modprobe It's a very old nvidia-modprobe, but oh well. X won't start. No graphics. If I don't install nvidia-modprobe graphics work but boinc won't find the cards... And yes, I do restart boinc-client, but that does not help boinc find the cards. So I aborted the Seti GPU tasks in hand. A lovely bunch of GPU tasks that I have no way to process right now... Doing cpu for now on 11 cores. |

I meant Xubuntu, not plain Ubuntu. 16.04 will be officially marked LTS in the repositories in a month or so and when it is I'll upgrade. In hopes it will help with GPU on boinc. Sensible to do anyway. |

It's probably just another problem with the repository driver. I'm using 364.19 from nVidia and it seems to be working fine with Ubuntu 3.13.0-88; http://setiathome.berkeley.edu/show_host_detail.php?hostid=7258715 |

I managed to install the official NVIDIA latest driver to my ubuntu 15 for the first time ever. I had to apt-get purge/remove all nvidia*, uninstall lighdm, try kde and uninstall that and then install lightdm and nvidia drivers. It took me a week and I did not write down everything I did. But it is doable. Petri (Pee Tree) To overcome Heisenbergs: "You can't always get what you want / but if you try sometimes you just might find / you get what you need." -- Rolling Stones |

My concern is that it is (apparently) the old nvidia-modprobe that (in 14.04) kills X/lightdm. Why that has not been updated in sync with the drivers (in ubuntu) is a puzzle. Someone thinks it's not needed? Do you have nvidia-modprobe petri33? Without nvidia-modprobe the desktop (xfce) comes up fine with either nvidia driver that 'additional drivers' shows. But boinc cannot see the GPUs. |

Updated kernel installed June 28 and installed and ran nvidia-modprobe (same one as before) and X/lightdm stay operational. So GPU operations have been resumed. a fair number of GPU tasks validated overnight. On one task 5008182283 I got: ERROR: Possible wrong computation state on GPU, host needs reboot or maintenance which is alarming. I'll be watching all this closely. |

Someone thinks it's not needed? I prefer Ubuntu 15.10. And this no gpu is found could be solved with that: https://boinc.berkeley.edu/dev/forum_thread.php?id=6307 ok, here is a shortcut installion instruction from me :) http://setiathome.berkeley.edu/forum_thread.php?id=79358 |

Thanks for the links, The_Matrix. |

The failed task I mentioned yesterday is failed for 4 others (3 have GPU related messages suggesting reboot same as I got, 1 has complaint about too-old GPU.) So I guess that task failure is nothing I should worry about. |

So far my experience with nVidia drivers on Linux is you get it to work once, then don't touch anything again. |

I prefer to keep up with bug fixes. Only one machine has the nVidia driver problem, and that is only with some kernel releases in 14.04 LTS. So I occasionally struggle :-) Two nvidia GPU machines here on 14.04 are updated too and just work without surprises. |

New Linux kernel today. Install went fine, GPUs fine, Seti working fine. |

New Linux kernel today. Install went fine, GPUs fine, Good that a new kernel worked. For reference for others: Which kernel version did you need to move up to to get it working again? (I guess a 2014 distro is nearing end of support? Or is that one a "LTS"?) Happy cool crunchin', Martin (A quick way to find out is to open a command line and give the command: uname -a to show the system name and kernel name.)
