Hi Sebastian,

http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-
raring.git;a=commit;h=f6a1af4e27a20de1b4b753b23ba437394384f380 seems
like an improvement for your machine. But alas, apparently it's not
enough.

Title:
  vgaswitcheroo on the Macbook Pro 8,2 high-res

Status in The Linux Kernel:
  Confirmed
Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  I have the same issue as in Bug #1171940. The difference is that my machine is slightly different (High-Res display) and the pci id is somewhat different. So I edited the patch supplied there and try to fix the issue. However the screen still stays black.
