Title:
  Mini display port not working

Status in “xorg” package in Ubuntu:
  Expired

Bug description:
  I am trying to use the mini display port to connect to an external
  monitor using the mini display port. I have confirmed this works using
  another laptop. When plugging this into my Ubuntu machine (Dell XPS17)
  the monitor is not detected.

  There is no screen flash or anything in the Xorg log or dmseg that
  suggests the port has been plugged in.

  I have tried adding the monitor using the following:
  xrandr --addmode DP1 "800x600"
  xrandr --output VGA1 --mode 800x600 --right-of LVDS1

  Which results in the laptop screen flashing but not the external
  monitor and the following is printed to the terminal:

  xrandr: Configure crtc 1 failed

  xrandr -q gives the following:

   xrandr -q
  Screen 0: minimum 320 x 200, current 1600 x 900, maximum 8192 x 8192
  LVDS1 connected 1600x900+0+0 (normal left inverted right x axis y axis) 382mm x 214mm
     1600x900       60.3*+
     1440x900       59.9  
     1360x768       59.8     60.0  
     1152x864       60.0  
     1024x768       60.0  
     800x600        60.3     56.2  
     640x480        59.9  
  VGA1 disconnected (normal left inverted right x axis y axis)
  HDMI1 disconnected (normal left inverted right x axis y axis)
  DP1 disconnected (normal left inverted right x axis y axis)
     800x600        60.3  

  I have also tried updating to the latest intel driver by using:

  intel-linux-graphics-installer

  This succeeded however has not solved my issue.

  I also have bumblebee installed however I understand that on this
  machine the mini display port runs from the intel chip so this should
  not be impacting this issue. I include this information incase it
  might.

  I am more that happy to run any diagnostics required to help resolve
  this issue.

  Many thanks in advance for your help!
