[Nouveau] newbe guidance for Alienware 13

[don fisher]

I had desire for a light laptop, so purchased an Alienware 13. I am 
currently unable to display on the external monitor, leaving me with the 
small 13" display. I am ignorant of how to proceed. I assume the Nouveau 
  driver is being used, but am not sure. I it Intel or Nouveau?  When I 
boot the following appears in dmesg:
   nouveau: detected PR support, will not use DSM
   nouveau 0000:01:00.0: enabling device (0006 -> 0007)
   nouveau 0000:01:00.0: unknown chipset (136000a1)
   nouveau: probe of 0000:01:00.0 failed with error -12

If I do an lsmod | nouveau i get:
101:nouveau              1691648  0
103:mxm_wmi                16384  1 nouveau
104:i2c_algo_bit           16384  2 i915,nouveau
107:drm_kms_helper        167936  2 i915,nouveau
111:ttm                   110592  1 nouveau
117:drm                   397312  6 ttm,i915,drm_kms_helper,nouveau
118:wmi                    16384  3 dell_wmi,mxm_wmi,nouveau
119:video                  45056  3 i915,dell_wmi,nouveau
120:button                 16384  2 i915,nouveau

This shows the nouveau driver and the Intel i915 driver. Which is 
running the display, and how can I  control it?

The device from lspci is:
01:00.0 VGA compatible controller: NVIDIA Corporation GP106M [GeForce 
GTX 1060 Mobile] (rev a1)

Please advise if there is a path available.
