Comment 26 for bug 1758243

FWIW, I've found that optirun doesn't work in Ubuntu 18.10 - the nvidia module loads but as soon as the application tries to create a 3D window, the appliction exits - but primusrun does work, so long as you ensure the path to its libGL is correct, as per https://github.com/Bumblebee-Project/Bumblebee/issues/951#issuecomment-379512353:

eg PRIMUS_libGL=/usr/lib/x86_64-linux-gnu/libGL.so.1 primusrun 0ad

or I think you can also modify your primusrun file directly, as per https://github.com/Bumblebee-Project/Bumblebee/issues/951#issuecomment-412314114.
