Remove all automatic brightness adjustments

+It seems like this is the main reason why auto-mode doesn't always get
things quite right.  Since auto-brightness can be enabled in the OS,
just use that.  Maybe in the future, auto-mode will automatically set
auto-brightness on if it is not already, but this may be pointless.

tl;dr

More research needed to fine tune auto-mode
