how to disable the animation of dimming the screen when ubuntu turns inactive screen off

  • 772

When Ubuntu 13.10 decides to turn of inactive screen, it runs an animation for 15 seconds long, slowly dimming the screen.

The purpose, I assume, is to give an interim for human intervention - a user reading the screen can touch a key or move the mouse to brighten up the screen, preventing the turn-off.

However it failed the purpose on my Acer Iconic W500, where the keyboard and mouse are both locked up during dimming.

The user sits sadly and helplessly waiting for the screen to dim to complete black, and then can he light it up with a mouse move or keystroke.

How irritating it is to break the user away from reading a complicated article that forced him still for 10 minutes!

It may be a bug, and is perhaps filed somewhere (a quick search didn't reveal one).

Here I am asking only for a workaround, e.g. to turn off the dimming animation. If screensaver decides to turn of the screen, let it turn it off immediately so the user can quickly wake it up, thus being less a nuisance.

    Method1:

    To get started, open Brightness & Lock utility from Unity Dash search results or from System Settings.

    enter image description here

    Un-check the box where it says “Dim screen to save power”

    Method2:

    To get started, open dconf Editor from the dash search results.

    enter image description here

    In next window, navigate to org -> gnome -> settings-daemon -> plugins -> power. You’ll find the key which says “idle-dim-time”, change its value to 0

    If dconf-tools is not installed you can install it via the command

    sudo apt-get install dconf-tools
