Sure it does. It's common for nvidia-based machines to use the GPU's built-in backlight control, and when that's the case the appropriate place for the control code is in the driver that touches the rest of those registers - nouveau, in this case. > But there are things called "platform drivers" that support all those > non-standard features you may find on laptops, like radio switches, > leds, ... and backlight.

But in some cases (nvidia-based Sonys, for instance) there's no platform interface to use. -- Matthew Garrett | [email protected] _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
