Hi, My Hardware : macbook pro 8.2 OS: Ubuntu 12.04 I've tested on linux 3.6.2 with patchs 0002 to 0008 only, the others one are already included in 3.6.2 Linux EFI stub boot with the following options : [ 0.000000] Kernel Command line: vmlinuz-3.6.2.efi root=UUID=xxxxxxxx ro add_efi_memmap i915.lvds_channel_mode=2 i915.modeset=1 radeon.modeset=1 elevator=noop vt.handoff=7 initrd=EFI\gmux\initrd.img-3.6.2 Good news, the radeon card is recognised with an EFI stub boot only ! But the screens stay black !! (lcd panel and hdmi) ..., X is started because I heard lightdm ubuntu sound, but all are black, no X and no console frame buffer. grep drm /var/log/dmesg.0 [ 2.657608] [drm] Initialized drm 1.1.0 20060810 [ 2.714673] [drm] Supports vblank timestamp caching Rev 1 (10.10.2010).
