    My Linux rig used to crunch happily but suddenly doesn't detect my GTX560 anymore.

    Restarting the computer doesn't help. Restarting on an older kernel doesn't help, installing cuda 331 "updates" doesn't help. Restarting BOINC via a command prompt in the terminal doesn't help.

    My nvidia driver is the 331.113 and my OS is Ubuntu 14.04 64 bits.

    I am half tempted to update my system to 14.10 but i would like to avoid that. Besides, my system hangs every three days.

      I went back to 304 drivers. Mine stoped working after an update. 331 drivers no longer worked. Mint 17.

      What I noticed with the newer

        What I noticed with the newer NVIDIA drivers is that there is now a separate kernel module that has to be loaded in order for BOINC to detect the NVIDIA devices. This module is called nvidia_uvm.

        With older drivers, only the nvidia module was needed. Based on that, running this as root with the newer drivers may work.

        /sbin/modprobe nvidia_uvm

        I was able to get BOINC to detect NVIDIA devices via driver 346.16 provided the above kernel module was loaded.

        Latest 14.04 update broke

          Latest 14.04 update broke CUDA use for me.

          Was 331.28 (worked) now 331.113 (no CUDA, boinc does not recognize)

          sudo modprobe nvidia_uvm
          did not help (I assume reboot
          after that command not needed...)

            I can confirm installing nvidia-modprobe solves the issue.
            Both driver versions - 331 and 304 had the same problem on Xubuntu 14.04 64bit with nVidia GTX570.

              Shafa is right. Enabled Trusty-Backports so I could install
              nvidia-modprobe. Installed it and ran it.
              Made no visible difference in the output of
              lsmod|grep nv
              but after
              sudo /etc/init.d/boinc-client restart
              now boinc sees my GPUs and nvidia_uvm suddenly
              shows up in the output of
              lsmod|grep nv
              !.

              GPUs at work again! Thanks!
              See Ubuntu bug 1361207 for additional details if you care.

                On Ubuntu 14 you need to install nvidia-modprobe or Boinc will not detect the GPU but Ubuntu will happily use it. Inserting sleep command, moving Boinc to the end of the start up sequence etc. doesn't work as without modprobe Boinc does not see the GPU. After installing Boinc from repository and installin nVidia drivers you need to do the following

                sudo usermod -a -G video boinc

                ( this adds the unprivalidged boinc account to the video group )

                sudo update-rc.d -f boinc-client remove
                sudo update-rc.d boinc-client defaults 99

                ( move BOINC start-up to the end of start-up processing )

                sudo apt-get nvidia-modprobe
                sudo modprobe nvidia_uvm

                ( without nvidia-modprobe installed boinc will not find the GPU )

                sudo service boinc-client restart

                ( restarts the boinc client )

                  Three weeks ago I upgraded to 64 bit 14.11 and ran smack into this problem! Since then I have been working on getting my GPU working in Boinc.

                  Today I found this thread and downloaded Nividia modprobe...Bingo my computer started downloading GPU boinc files...Thank you soooo much!

                    I'm having the same problem where boinc does not recognize my GPU. I tried getting modprobe using the command bellow.

                    sudo apt-get nvidia-modprobe

                    but when I ran this code it response with,

                    Invalid operation nvidia-modprobe

                    I am running Mint17, does anybody have an idea what I'm doing wrong.

                      Which nvidia drivers do you have installed?

                      I am running nvidia driver: 340.65 on Ubuntu.

                      If you have drivers installed try:

                      1. "sudo service boinc-client restart" - without the quotes
                      if this does not work try
                      2. a restart

                        I ran "sudo service boinc-client restart" and restarted the computer and boinc manager but still get this message from my event log in boinc.

                        from what I can tell from the other messages I need to install nvidia-modprobe but I can't seem to find them when using the apt-get command.
