Screen brightness never listens

[Removed by request]

I can never get the screen brightness to obey me on ubuntu. It's to the point where I'd move to Mint. The setting is simply a checkbox in the settings, and when unchecked, apparently the screen still follows the "90 seconds" until dimming the screen.

It should stay bright :/
