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.
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
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.
