Everything used to work until recently. Now, whenever I connect my HDMI monitor to my laptop nothing happens. Running xrandr doesn't show the HDMI output. Can anyone help out? I've been trying to fix this for the last 3 hours. I even reinstalled unity but that didn't work. I'm on 14.04 ubuntu. Any help is appreciated!!VladimirxrandrScreen 0: minimum 320 x 200, current 1360 x 768, maximum 32767 x 32767eDP1 connected primary 1360x768+0+0 (normal left inverted right x axis y axis) 344mm x 193mm       1920x1080      60.1 +   59.9     40.0         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  VGA1 disconnected (normal left inverted right x axis y axis)VIRTUAL1 disconnected (normal left inverted right x axis y axis)

Ok, after a sleepless night of googling and trying things out (like reinstalling unity and the x drivers), I decided to try out Intel's approach. Apparently they officially support linux and they have a graphics driver installer (link below). After downloading and installing everything started working again. I'm in Ubuntu heaven again.
