Lenovo P51 simultaneous working of two videocards issue.

Hi. Lenovo p51 has two videocards:

1) 01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M1200 Mobile] (rev a2)
2) integrated intel video.

The issue is that I want to use simultaneously two external video ports HDMI and thunderbolt.
HDMI is binded to intel, and Thunderbolt - to NVIDIA.
I tried to install second driver (pacman -S nvidia)

Setup in BIOS: discrete graphics

After a reboot I got horrible screen glitching.
Does anybody successfully get  to work two drivers on this machine?

Thanks.

P.S. Also I found that with main 'linux' kernel package graphics works really unstable under i3wm windows manager. So I switched to 'linux-lts' package which is more stable.

Hi, this guide works if you use nvidia+bumblebee along with the integrated graphics card. You basically have to start a new X server for the thunderbolt port wired to the nvidia card.
