hdmi not showing up in xrandr

6,973

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.

Enjoy!

    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!!

    Hey @Pixel thanks a lot! This is looking promising! Since now, everything is working good so far and i don't want to experiment. But going to bookmark this.

    @Pixel hey, sorry for the delay... I'm trying to remind myself what exactly did the trick, but can't remind, since I've tried a ton of things. I've struggled so hard with this by spending around 36h (with just few hours of sleep) to solve this. I can remember that I've completely removed any nvidia drivers and installed the latest version. The version: 435.21. I can remind that i've instaled CUDA too (check this: docs.nvidia.com/cuda/cuda-installation-guide-linux/index.htm‌​l). Also, try to install intel graphics before, mentioned above. Let me know how's going.
