The ranges are different, though: intel_backlight/actual_brightness:1000 intel_backlight/bl_power:0 intel_backlight/brightness:1000 intel_backlight/max_brightness:4437 intel_backlight/type:raw acpi_video0/actual_brightness:41 acpi_video0/bl_power:0 acpi_video0/brightness:41 acpi_video0/max_brightness:100 acpi_video0/type:firmware I guess I need to write me a dirty script for now ... :-) Thanks guys. _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
