In the GENERIC config: > > # genfb* at pci? dev ? function ? > genfb0 at pci1 dev 0 function 0 > genfb1 at pci0 dev 1 function 0 Are you saying that gop will always use genfb0, and that connecting genfb0, in the kernel, to the other radeon device/output (on pci1, dev 0 fn 0) would make the monitor show all the output, disabling the laptop LCD? Hmmm, worth trying. Let me get the source code and try. Given that I was contemplating on changing the readeon_bios.c file to see where it was returning false and giving the kernel error.

I am not looking to get multi-car support, or support for two monitors. I am trying to adjust the brightness, and was thinking of connecting my external LCD monitor via VGA to the system and get output. > > -RVP Riza
