I posted this question as I am encountering display problems after upgrading Ubuntu 15.10 to 16.04. I went into 'additional drivers' & noticed this:

I was wondering whether purging the current drivers & 'reinstalling' them again would help detect the graphic hardware I have on my system. For info, my system is a Lenovo X220 Thinkpad: i5 2420M 6Gb RAM Onboard Graphic Card

Any suggestions would be great help. Many thanks,

I had a similar issue, and this worked for me:

sudo apt-get update
sudo apt-get install --reinstall xserver-xorg-video-intel xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg

Followed by a reboot. Was having many irritating graphics crashes before, none since. It oddly didn't make Ubuntu recognise the device, but at least I'm not getting crashes now.

Using an updated gcc (6.2.0) and a newer kernel (4.8) was helpful for me. I couldn't upgrade to 16.04 from 14.04 and couldn't risk destroying a system I've built for years. Looks like I'm going to be building my Ubuntu software manually from now on..
