Ubuntu: hdmi not showing up in xrandr


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!!

Graphics card:

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)


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.
