AdjBrightness works, and so does Light Flow, to turn the lights off. Unfortunately, Light Flow and BattMonX don't seem to play well together, or at least act tetchy at times.
LOL, yeah, you'd have to turn off the LED Notifications setting in BattMonX to allow Light Flow to have control of the LEDs, and just use BattMonX for the notification status bar icon.
Too many cooks in the kitchen, so-to-speak, when you have two apps that both want to use these FIFO resources (i.e., the LED). The non-root mode of my app should work okay with Light Flow, but you wouldn't necessarily know which app has turned on the LED for what function.
Cheers!
(It's always someone else's fault, right?)
