So there is now a proprietary graphics ppa that is (as I understand it) a collaboration between Nvidia and Canonical. You install the nvidia drivers from there and can also install a command line tool called "prime-select". You can then select which "profile" you want to use via: $ sudo prime-select [nvidia|intel] Then a logout and log back in will swap the adapter in use. From there you will be using either the intel or the nvidia chip full time. Bumblebee is an option...but you would have to mark special commands with "optirun" and would be suffering a performance penalty. But it is a good option if you don't want to deal with the logout to swap. For me, I don't mind the logout for swap so I just use the "prime-select" tool. Edit: Here is the ppa: https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa It looks like there is a bumblebee something in there. Here is a news blurb about it: https://itsfoss.com/ubuntu-official-ppa-graphics/ https://itsfoss.com/ubuntu-official-ppa-graphics/

Thanks for the update, I ran Bumblebee a few times for OpenGL intensive things and the heat management and general perfomance of the Dell XPS (from 5? years ago) was worrying. I also thought the weird loop-through was weird, how the results would be passed back to the built in graphics, plus the ports weren't mapped properly, so you only had two screens on built-in graphics - the Nvidia bit didn't have any connection to the HDMI in Linux mode. So it was far from the effortless high speed awesome graphics expected, every 'bumblebee' invocation had all the convenience of a helicopter ride. Sounds like the prime-select tool is what I needed. Oh well, glad I went from cutting edge SGI Infinite Reality 3D to integrated graphics over the years.
