same at my P50. Is there any solution without installing xfce.
dmidecode info:
# dmidecode 3.0
Vendor: LENOVO
Version: N1EET57W (1.30 )
BIOS Revision: 1.30
Firmware Revision: 1.15
Product Name: 20EN0004PB
SKU Number: LENOVO_MT_20EN_BU_Think_FM_ThinkPad P50
Product Name: 20EN0004PB
In BIOS I changed Display: Hybrid Graphics to Disabled just to use Nvidia GPU,
is it correct?
If it helps if I updated bios to the latest 1.37?
Thx. in advance.
Btw. What is the status of this issue? Is there any progress?

Title:
Multiple monitors broken
Status in nvidia-graphics-drivers-361 package in Ubuntu:
Confirmed
Bug description:
I have a Lenovo P50 with Nvidia Optimus (Quadro M1000M), installed with
Ubuntu 16.04 and the recommended Nvidia drivers (361.42).
I added two external monitors connected to DP sockets in the docking station.
I would like to have display shift to those two monitors when the laptop is
docked. One monitor has native resolution of 1680x1050 and the other is
1920x1080. The laptop native resolution is 1920x1080.
Expected result:
laptop monitor shut off, two external monitors running in native resolution,
display shared on both monitors (not mirrored).
Process:
I configured the display using the "Displays" applet in the unity control
center. However, pressing "Apply" when changing a specific display setting
(such as resolution, location of screen relative to others, turning on/off),
results in a long period of darkness, usually followed by display falling back
to mirroring of all 3 monitors, using a similar-size screen (either low on all
or high on all with the low-res monitor using panning). The applet remains
frozen for some time, with the dialog "Is the display ok" open but
unresponsive. Later I realized this is because there is another dialog of
"Cannot set screen CRTCXXX" hidden under the two above windows, which needs to
by ok-ed first.
Extra:
I also tried setting the display manually with 'xrandr', which lead to a
similar result as above - with the "cannot set screen" dialog, and falling back
to mirroring. This convinced me that the problem is probably with the nvidia
driver and not the higher plumbing.
