Title:
  HDMI no longer available

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  As of linux image linux-image-3.13.0-62-generic the HDMI port of my
  Dell Inspiron 15 stopped working:

  $ xrandr
  Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 32767 x 32767
  eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 194mm

  The only thing I could do was downgrading the image:
  $ sudo apt-get install linux-image-3.13.0-61-generic
  $ xrandr
  Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 32767 x 32767
  eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
     3840x2160      60.0 +   48.0
     2048x1536      60.0
     1920x1440      60.0
     1856x1392      60.0
     1792x1344      60.0
     1920x1200      60.0
     1920x1080      59.9*
     1600x1200      60.0
     1680x1050      60.0     59.9
     1600x1024      60.2
     1400x1050      60.0
     1280x1024      60.0
     1440x900       59.9
     1280x960       60.0
     1360x768       59.8     60.0
     1152x864       60.0
     1024x768       60.0
     800x600        60.3     56.2
     640x480        59.9
  HDMI1 disconnected (normal left inverted right x axis y axis)
  VIRTUAL1 disconnected (normal left inverted right x axis y axis)

  Will this be fixed with the next linux image update? Otherwise, I have
  to pin the current version.

  Best
