[Solved] Backlight resets after some time or mouse move

Hello, I have tried various things,mainly all of them are listed here. My problem is, after I set brightness level, after some or when watching some youtube video and move mouse after that, screen brightness reset to max, indicator shows it hasn’t changed. Any ideas on how to fix it ?

Have you checked your power management settings it can be found in the screen saver settings there is two options ac power and battery in battery there is a setting under display menu called reduce Backlight and dim display when idle uncheck both of these it help me another option might be to use the panel applet called inhibit applet hope this helps

That worked, thank you, although had to remove xbacklight, but that was piece of cake solution.
