I didn't get much luck using external displays either. I'd love to hear from others who may have success though.

Heeey. I had luck using Ubuntu Gnome 16.04 LTS ! Nvidia Driver 381. Multiple Display works when Nvidia is active. I´m using Bumblebee too. Kernel 4.10.

What i also realized that the Switch with FN + F7 , has an effect on the hardware. It doesnt boot when i selected the dedicated graphics only mode.

This tutorial helped me: https://gist.github.com/whizzzkid/37c0d365f1c7aa555885d102ec61c048

@Sijoma how did you make the external monitor work ? I used prime-select nvidia, then I connected the HDMI and It can't detected!

I use bumblebee alongwith intel-virtual-output and it works out pretty well for me. I used the Arch Linux Bumblebee guide. When I need more performance, I drop the intel-virtual-output, start a second X11 server and use hotkeys to switch input devices between the two X servers.

@sayash intel-virtual-output is returning [no VIRTUAL outputs on ":0"] , I tried to follow this one here and still the same : https://unix.stackexchange.com/questions/321151/do-not-manage-to-activate-hdmi-on-a-laptop-that-has-optimus-bumblebee

I tried with manjaro didn't work also, I am using ubuntu now but can't use external display

I used the link i provided. (https://gist.github.com/whizzzkid/37c0d365f1c7aa555885d102ec61c048) And i made sure that both cards are active with FN +F7 in windows. This has a permanent effect, also for other operating systems.

My steps for enabling external monitor:

  • Install nvidia 390 driver on ubuntu (this gave me a login loop bug so ubuntu was unusable)
  • Go on to windows side and press fn-f7, restart at the prompt (this enables your gpu as default at a bios level)
  • Log in to ubuntu again (should now be working properly)
