different resolutions on internal and external monitor possible with i830M?

[Wolfgang Pauli <ookami@gmx.de>]

Hi,

I have a 830M and want to run the external Monitor with 1280x1024 and the 
internal with 1024x768. But I can only run the external monitor with that 
resolution, if I unconfigure the internal monitor. Does anyone know what the 
problem might be?
