So I recently installed this firmware, and although the "non-mirrored" mode works fine, I can't seem to get the clamshell to work. I connect a keyboard, mouse, and the external display as one is supposed to, but when I shut the screen on the ibook, it just doesn't work! Unlike before getting this firmware, I can tell there is some output, it's just not anything useful. I have tried in both mirrored and non-mirrored mode. The computer acts like it works...aka the display goes to sleep and must be awoken as the instructions say, but it just doesn't work. Any ideas?
I have a G4 12", 1.33GHz running Leopard 10.5.8
