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:
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.
