Bug Description
On a fresh install of 12.04, on my Thinkpad L520, the primary monitor refuses to work. I can plug in an external monitor and it works fine, but the primary laptop monitor displays nothing.
There are no special drives that I know of for this graphics card, and it works fine in previous versions of Ubuntu.
(Previous versions need the 'noapic' flag to boot though).
What can I do to debug and get this fixed?
It's a deal breaker, I can't upgrade to 12.04 until I can use my laptops primary screen.
