Hi... I am trying to get external displays to work with a 15" 1GHz Powerbook.
So after googling for some time I found http://people.ecsc.co.uk/~john/documents/powerpc/ which works when connecting an analogous monitor with a pretty yellowish screen (cannot be recognized by just starting X and seeing the black/white pattern)... Certain options cause the machine to freeze but give correct color... so I guess there is some conflict between the fb and Xfree driver. However I was able to get X working when a DFP (external TFT at 1600x1200) was connected. Unfortunately the internal display was then displaying weird stuff, and as I was afraid of destroying some hardware I quickly shut down X. So for me it looks like the fb driver can do certain parts to allow for external displays aswell as the X driver... but they seem to collide for certain settings. I am on 2.4.20-benh10 / XFree86 4.3. I wonder whether someone has it working ... ? I guess it would be best to have XFree allowing for dynamically adding screens... and to turn on a second display with some tool... mirroring makes no sense in 99.99% of the cases as there is no monitor/DFP correctly displaying 1280x854 ... As this is the *only* thing not working perfectly on the 15" powerbook series it is probably worth investing quite some time... so I am very open for discussion. Best, Soeren.
