I have see a couple similar questions with this problem, but none of the solutions have worked for me.

This is on an Asus laptop with a built-in graphics card. lspci | grep VGA shows:

00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)

The output of xrandr doesn't detect anything with the monitor plugged in.

I have tried two things so far, installing an Nvidia driver as described here:

Ubuntu 16.04LTS extended display not working

and upgrading the kernel as described in this blog post:

http://linuxdaddy.com/blog/install-kernel-4-4-on-ubuntu/

Neither had an effect. Any suggestions would be appreciated!

I don't know exactly how, but I got it working. I uninstalled the Nvidia drivers and rebooted. My best guess is that the 4.4.8 kernel with the original drivers is what I needed.

  • you don't seem to have an nvidia card anyway , try lspci | grep -i nv – Amias Oct 25 '16 at 14:34
  • You're correct. lspci | grep -i nv doesn't find anything. – Jessime Kirk Oct 27 '16 at 19:56
