primusrun glxgears -info

Looks like the nvidia module is not loaded

  1. Run the following to check you have the module installed

    lsmod | grep nvidia

  2. Blacklist nouveau in /etc/modprobe.d/blacklist.conf by adding the line

    blacklist nouveau

  • This is unclear. What is the user supposed to do if lsmod | grep nvidia shows that the nvidia module is loaded? What is the user supposed to do if the nvidia module is not loaded? Why? – G-Man Dec 9 '18 at 19:08
  • The log file shows nvidia module is not loaded. So either its bumblebee config problem or nvidia driver installation . so I think if lsmod shows nvidia modules loaded then its bumblebee config problem. And he need to remove KernelDriver=nvidia-current to only "nvidia" and also need to add line Module = nvidia – Dipesh patel Dec 10 '18 at 5:23
  • Still, your answer could be clearer on the instructions to be completed. – Paradox Apr 5 at 22:02
