@zubozrout: I got the same error (Module 'nvidia' is not found) when I tried it just now. I had to alter the /etc/bumblebee/bumblebee.conf XorgModulePath in 18.10 to get optirun to work with the nvidia 415 driver:
XorgModulePath=/usr/lib/x86_64-linux-gnu/xorg,/usr/lib/xorg/modules,/usr/lib/xorg/modules/input X and restart bumblebee (sudo systemctrl restart bumblebeed). Note that the path used to start with /usr/lib/x86_64-linux- gnu/nvidia/xorg, but it looks like the module now goes just in /usr/lib/x86_64-linux-gnu/xorg: $ ls /usr/lib/x86_64-linux-gnu/xorg libglxserver_nvidia.so libglxserver_nvidia.so.415.25 nvidia_drv.so Not finding bbswitch shouldn't be such a big issue with newer kernals, because the kernel should be able to suspend the card automatically. You could try the latest bumblebee testing PPA (https://launchpad.net/~bumblebee/+archive/ubuntu/testing) and put this line into the [driver-nvidia] section of bumblebee.conf before restarting it: AlwaysUnloadKernelDriver=true For more details, see https://github.com/Bumblebee- Project/Bumblebee/issues/978 and specifically https://github.com /Bumblebee-Project/Bumblebee/issues/978#issuecomment-415332707. There's no cosmic driver in that PPA, but the bionic one works just fine on my cosmic. ** Bug watch added: github.com/Bumblebee-Project/Bumblebee/issues #978 https://github.com/Bumblebee-Project/Bumblebee/issues/978 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1758243 Title: bumblebee needs configuration changes to work with nvidia-driver-390 and libglvnd0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bumblebee/+bug/1758243/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
