Public bug reported:
As of linux image linux-image-3.13.0-62-generic the HDMI port of my Dell
Inspiron 15 stopped working:
$ xrandr

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

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.
