Screen doesn't load with Intel graphic cards on laptop...

[Axx83]

Hello, I bought and played Overture and BlackPlague on my old pc, a desktop with nvidia card running Ubuntu. Everything went fine.
But now I'd love to buy and play Requiem for my laptop...unfortunately it doesn't seem to be working, here's what I did:

I install the demo on my Thinkpad X60s with ubuntu and run it, the game starts and let me choose config. I put everything to minimum/off and select new game.
If I choose the tutorial it starts and let me pass it, if I complete it or if I skip it the screen says loading then it goes off and nothing happens, black screen forever unless I kill the application.

My card is: Mobile 950GM Express Integrated Graphics Controller

thanks
