How To Force Set Display Brightness On Startup Under Ubuntu 12.10/12.04/Linux Mint 14/13



In this tutorial, we will see how to force your system to set a custom brightness level each time you log in to your session under Ubuntu/Linux Mint. To make this possible, we will use xbacklight and Startup Applications. This tip is useful for users of laptops.

Getting Started

Let's first install xbacklight with this command:


sudo apt-get install xbacklight

Open "Startup Applications" and add the following details:

  • Name: Brightness
  • Command: xbacklight -set 60
Replace 60 with any brightness value of your choice (70, 80, etc.), then click Add:


On the next reboot, your system will set the selected brightness level automatically after you log in.

NOTE: This tip is workable under Ubuntu 12.10/12.04/11.10 and Linux Mint 14/13.
