Adjusting backlight using the laptop keys for this work in KDE when I boot with acpi_backlight=vendor and without invert_brightness=1. I am not sure if the buttons work the right way, though (never seen which should increase or decrease the brighness), so it might be inverted. Is it possible to tell acpi_backlight to invert the brighness setting? Would it affect i915 too? -- Happy hacking Petter Reinholdtsen _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
