The linux kms drivers simply use the kernel's mode database, to provide a list of standard resolutions. Additionally you also can define your own resolutions, using xrandr --newmode & --addmode). If we want go beyond passing a simple "please use <width>y<height>" we probably should generate a edid block and pass that to the guest, but I don't see a strong reason to do so. cheers, Gerd
