I am running Ubuntu 16.04 LTS 64-bit on my HP Zbook which has a Nvidia Quadro graphics card. I am not able to detect multiple displays, whether I try to connect them through HDMI,VGA, or Thunderbolt 3 dock. It doesn't show up on display settings.
lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 06) 01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M1000M] (rev a2)
Now I obviously researched this problem as soon as I encountered it (my previous question that did not get any answers) and I have seen (and tried) multiple solutions such as those given at this forum answer and this forum answer. The problem is whenever I try to install nvidia drivers (which supposedly is the most common solution), such as those given on the first link, Ubuntu boots into a blank screen, or I keep looping through login screen after entering password (both of which apparently are known problems while messing with graphics drivers w.r.t. Ubuntu).
The only way I can log into Ubuntu again is by purging the nvidia drivers and reinstalling xserver (using the nouveau drivers as shown below). I have tried reinstalling nvidia drivers multiple times but goes into black screen every time.
Clearly I am either doing something wrong, like installing the incorrect version of nvidia drivers, or using the wrong non-proprietary drivers. If anyone has faced this problem before or has a solution to this, I welcome those suggestions.
Output of xrandr:
xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080 default connected primary 1920x1080+0+0 0mm x 0mm 1920x1080 77.00*
Please post any diagnostic command requests and I will post those outputs in the edited question.
Thanks in advance
