Soft Brightness Gnome Shell Extension

Brightness slider in Gnome Shell's system menu

Overview

Soft Brightness uses an alpha overlay to control the brightness on all or some of your monitors. It integrates smoothly Common uses are:

  • Your laptop has no back-light, maybe because it's not supported, or you have an OLED display.

  • You want to control the brightness level of external monitor like you do with your built-in screen.

Bonus features:

  • Minimum brightness level: do not get lost in the dark.

  • Can operate the shell in tear-free (VSync) mode at all time.

Configuration

Soft Brightness comes with a configuration panel, which can be accessed from the "Tweaks" application or the Gnome Shell Extensions page.
