Nice, in your older mail I read: > The PEGP.DGFX acpi device was binding to > acpi/video driver, the above ASL code emit a 0xD0 bus event to > video.c but cann't process it.

I'm working on the code to deal with it, the latest patches are here: http://lists.freedesktop.org/archives/dri-devel/2012-July/025646.html You first need this one with the ACPI header: http://lists.freedesktop.org/archives/dri-devel/2012-July/025517.html and the other 3 that you've already tested. With my patches on top you should be able to change the brightness using the hotkeys. I'd be grateful if you could test them :-) Luca _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
