Ubuntu 12.04 won't recognise my 2 monitors

view full story

http://askubuntu.com – I've got 2 monitors plugged into my nvidia quadro fx1700 graphics card but Ubuntu only recognises my HD monitor (says its a laptop monitor) and ignores the other one. Is there any way I can force it to recognise the other monitor? I have seen on other posts that the laptop thingis just a bug. (HowTos)
