this disables the light sensor so that the backlight is not adjusted with changing light conditions. You can still adjust the backlight using the dim and bright buttons above the 7, 8 and 9 on the keyboard and the display will still dim after a period of inactivity. Disabling the ALS is temporary, it'll be re-enabled after you reboot and you'll need to re-run the command. Feel free to share your experience with the ALS in the comments below.
Very helpful-thanks. Sitting with my back to a window on a sunny day it was always irritating to have the brightness oscillate every time a cloud floated by. Should really be an Option to disable.ReplyDelete
