I am using Dell Inspiron 15 (3542, early 2014). There's an annoying feature which adjusts the LCD brightness according to what's displayed on the screen.

When I was using Windows 8, I disabled it from Intel HD Graphics Control Panel > Power Saving > Disable Display Power Saving Technology, and it worked fine.

Now that I'm using ubuntu (and no longer have the HD Graphics Control Panel), is there any way to disable it?

what's your interest
