Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I am looking for a feature that I had before and I can't find no more.

At first, my screen would turn off gradually after being inactive for whatever many minutes it was set to. This gradual dimming was particularly useful when watching movies because it would anticipate me to move the mouse quickly before it went full dark.

And then I tried installing a screensaver and tweaked with Ubuntu here and there.

Unfortunately, the screensavers that I found didn't convince me to use them. But after the tweaking, the screen will turn off NOT gradually.

I wonder if someone knows how to set that up. Thanks.
