https://bugs.freedesktop.org/show_bug.cgi?id=26891 --- Comment #46 from Anonymous Helper --- Radeon now works for me on a MBP 8,2 booted from efistub in Linux 3.8.x. Can anyone else confirm this? You just need to make sure you add the PCI IDs to the xorg for both cards. Should Xorg detect them automatically? Is this another bug? Thank you! Now we just need the IGP to show something onscreen when switching to it and it will be perfect... -- You are receiving this mail because: You are the assignee for the bug.
