Unless I am severely confused (or the hardware was changed) there is no such feature. The XO does not have an ambient light sensor. The backlight is not turned off automatically in sunlight. Both "modes", reflective and backlit, are "active" all the time (unless the backlight is turned off manually). It's simply that under sunlight, the b/w reflection is much stronger than the colored backlight, so you are not able to see colors anymore. There is, however, a DCON mode specifically designed for the b/w reflective case, the anti-aliasing can be turned off and a color-to- gray mixing turned on, but again, this is done manually (in the current UI it is coupled to turning off the backlight). And, to dispel another myth, the frame-buffer resolution is not different in "b/w mode". It is 1200x900, all the time, color or not, and this is all that matters to software developers. The perceived resolution of hue gets lower due to the physical pattern of colored pixels, but perceived resolution of shade is as it was (modulo the blurring induced by the anti-aliasing). - Bert - _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
