Hello, I've made a small driver to set the backlight level on Apple MacBook Pro, for the models based on the Nvida video card (model 3,1 and 3,2). (if it works on other models please tell me) At the moment this is a quick and dirty hack, but you don't need to wear a pair of sunglasses anymore! Module (FreeBSD 7.1): http://user.lamaiziere.net/patrick/ambnb-270109.tar.gz The driver does not check if the hardware is a suitable Macbook Pro (TODO!), so use with care. You can check the model of your Mac with dmidecode: Handle 0x0011, DMI type 1, 27 bytes System Information Manufacturer: Apple Inc. Product Name: MacBookPro3,1 Version: 1.0 There is a sysctl hw.ambnb.level to set the level of the backlight (0 <= level <= 15). I don't have the time for the moment, but i will try to improve it a bit. I'm asking which method will be the best to interface the driver with userland applications? Regards.
