Okay I looked at the code to figure out what is happening and why only this driver has problems. The problem is that the framebuffer layer expects the backlight to be a seperate device. The reason being is that some embedded systems will use a gpio backlight. That way power management for a graphics card/backlight has 3 seperate states. Currently the intel DRM driver treats the backlight as being apart of the encoder. Jesse do you have objections to having the intel driver expose a backlight device. The bonus of that is the user can also set the backlight levels. ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
