I think figured out why.

The daemon in init.d sets the brightness level from /home/user/custom_brightness_settings

The beecon widgets store the brightness level in /home/user/bright_setting

every time I turn screen off and back on, daemon is resetting to the value in /home/user/custom_brightness_settings which never gets updated.

Is this your intended behavior, or should daemon and widget both use the same file for storing the brightness level?
