I'm noticing the display brightness auto-adjust in Lion seems to be less sensitive to light (more likely to dim the display) than on Snow Leopard running on the same hardware.

Is there a simple way to keep auto-adjust enabled, but change the neutral brightness offset so I don't have to keep turning it up all the time?

I guess I figured it out.

  1. Uncheck 'Automatically adjust brightness'.
  2. Set up desired brightness for current ambient light amount.
  3. Check 'Automatically adjust brightness' again.

Now it will adjust brightness properly.
