Video Bios
Looks like you only have DP outputs. Chances are the dock all plugs into DP-1 with a DP-MST hub with passive (or even active) adapters for DVI and HDMI. Unfortunately nouveau does not at present support MST. If you use the proprietary driver, I think those outputs will come out as DP-1.1, DP-1.2, etc. Thank you for your hints, Ilia. This made try one more thing I hadn't checked before: use one output on the dock and another directly on the notebook. And this does work, so I get eDP-1, DP-1 and DP-2 now. Out of curiosity, do you know if MST is considered or planned for nouveau? This works for me now! :happy: Linux 4.13.0-1-amd64 libdrm-nouveau2 2.4.83-1 xserver-xorg 1:7.7+19 xserver-xorg-core 2:1.19.3-2 xserver-xorg-video-nouveau 1:1.0.15-2 Thanks a bunch! |

Created attachment 122966 [details] the full kernel log I have a Lenovo P50 notebook with a docking station and two externally attached monitors, but I won't get more than one external "connected" display (+ the internal LCD). I tried to connect via DVI, DisplayPort and HDMI in all combinations, but xrandr only shows eDP-1 connected DP-1 connected DP-2 disconnected DP-3 disconnected Sometimes I manage to get both external monitors to display the same contents, but I have never managed to use one as primary and the other as secondary display. 01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M2000M] (rev a2) (prog-if 00 [VGA controller]) 01:00.1 Audio device: NVIDIA Corporation Device 0fbc (rev a1) Linux nb 4.4.0-1-amd64 #1 SMP Debian 4.4.6-1 (2016-03-17) x86_64 GNU/Linux xserver-xorg 1:7.7+14 xserver-xorg-core 2:1.18.3-1 xserver-xorg-video-nouveau 1:1.0.12-1+b1 libdrm2:amd64 2.4.67-1 libdrm-nouveau2:amd64 2.4.67-1 libegl1-mesa:amd64 11.1.2-1 libgl1-mesa-dri:amd64 11.1.2-1 libgl1-mesa-glx:amd64 11.1.2-1 libglapi-mesa:amd64 11.1.2-1 libgles1-mesa:amd64 11.1.2-1 libgles2-mesa:amd64 11.1.2-1 libglu1-mesa:amd64 9.0.0-2.1 libwayland-egl1-mesa:amd64 11.1.2-1 mesa-utils 8.3.0-1 mesa-vdpau-drivers:amd64 11.1.2-1 Bios is the most recent one from 2016-04-1 (1.21).
