Comment 31 for bug 828623

@Karl - I believe that your problem is not the same as this bug. Nouveau is having a hard time even detecting your eDP at all. There's a series of patches to improve Nouveau's eDP handling upstream (I *think* they're in the 3.1 kernel, but they might be landing in 3.2) - you could try a newer mainline build http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/ and see if that resolves your bug.

Sadly, those patches aren't likely to be backportable to the Oneiric kernel; they involve basically rewriting Nouveau's eDP support.
