# Soft Brightness Gnome Shell Extension
[![Build Status](https://travis-ci.org/F-i-f/soft-brightness.svg?branch=master)](https://travis-ci.org/F-i-f/soft-brightness)
![Brightness slider in Gnome Shell's system menu](docs/soft-brightness.png)
## Overview
Soft Brightness uses an alpha overlay to control the brightness on all
or some of your monitors. It integrates smoothly and does not
interfere with other Gnome Shell features. It works flawlessly with
the _Night Light_, the _Magnifier_ from the Accessibility Services, or
with screen captures (as long as they are initiated by Gnome Shell).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.
- Disables itself temporarily when a screen shot is taken.
## Configuration
Soft Brightness comes with a configuration panel, which can be
accessed from the "Tweaks" application or the [Gnome Shell Extensions
page](https://extensions.gnome.org/local/).![Soft Brightness preference panel](docs/preferences.png)
### Configuration Settings
#### _Use backlight control_
When enabled, Soft Brightness will work together with your computer's
back-light. The brightness slider and keyboard brightness hotkeys
will control both the back-light and the Soft Brightness overlays.
This is most useful:- if you have a back-light and _Monitors_ is set to _External_, or
- if a back-light is detected by Gnome but is not working (like some
OLED panel laptops which report having a back-light brightness which
doesn't exist). In that latter case _Monitors_ should be set to
_All_.If _Use backlight control_ is disabled, the Brightness slider will
only control the Soft Brightness overlays. The keyboard brightness
hotkeys will keep their default bindings.#### _Monitor(s)_
- If set to _All_, a brightness overlay will be added to all attached
monitors.- If set to _Built-in_, the brightness overlay will only be added to
the built-in monitor, which is the setting right below _Monitor(s)_.- If set to _External_, a brightness overlay will only be added to all
monitors which are not the built-in monitor, defined in the setting
right below _Monitor(s)_.#### _Built-in monitor_
A list of currently attached monitors is displayed. Pick from the
list which monitor should be considered the built-in monitor.The setting only has an effect if _Monitor(s)_ is set to _Built-in_ or
_External_.#### _Full-screen behavior_
Choose one of:
- _Do not enforce brightness in full-screen_: When an application
enters full-screen mode, remove the brightness overlays. You may
want to try this setting if your applications' refresh rate is
lagging in full-screen. The application will
[unredirect](https://passthroughpo.st/linux-desktop-compositors-performance-functionality)
its window and will bypass Gnome Shell's compositing (this is the
default for full-screen applications in Gnome Shell unless changed
by another extension).- _Brightness enforced in full-screen_: The brightness overlay stays
active when an application enters full-screen mode. This also
prevents the app from unredirecting its window (its surface will be
composited with Gnome Shell, and as a side-effect, will be subjected
to vertical refresh synchronization, ensuring tear-free rendering).
This is the default.- _Brightness enforced in full-screen, always tear-free_: Works like
_Brightness enforced in full-screen_, but will still prevent
full-screen applications from unredirecting their windows even if no
brightness overlay is active (brightness is 100%). Applications
will then always be rendered
[tear-free](https://en.wikipedia.org/wiki/Screen_tearing), whatever
the brightness may be. In this mode, Soft Brightness can be used as
a replacement for extensions like _Fix Fullscreen Tearing_.#### _Minimum brightness_
Sets the minimum allowable brightness for the display where _0_ is
completely dark and _1_ completely bright. Defaults to _0.1_ (10%).The minimum brightness will also be enforced for the panel back-light
if _Use backlight control_ is on.When the brightness is set to 0%, the display will go completely dark,
it may be hard to reset the brightness with the slider then.#### _Mouse cursor brightness control_
Toggles between having the mouse cursor brightness follow the screen
brightness (on/_true_) and keeping the mouse cursor at full brightness
(off/_false_).Gnome Shell's handling of cursor tracking can be sometimes buggy and
can show the wrong cursor type or size when the mouse cursor
brightness follows the screen brightness. It also introduces some
pointer motion lag.Note that if an other Gnome Shell component enables mouse tracking
(for example the Zoom accessibility option), then the mouse cursor
brightness will always follow the screen's.#### _Debug_
When toggled on, Soft Brightness will log extra debugging information
to the system journal (or syslog).This will be useful if you encounter a bug: In that case, please turn
_Debug_ on, and try to reproduce the issue with that setting before
capturing the debug logging.Soft Brightness's debug messages can be watched with:
```
journalctl -f | grep 'gnome-shell.*Soft-Brightness'
```### Effect on power consumption
Soft Brightness will cause extra load on the hardware and therefore
slightly increase power usage, as it needs to add extra alpha layers
and track the mouse among other things. This is true of any Gnome
Shell extension.If Soft Brightness controls an LCD panel, changing the brightness will
not change at all the panel's power consumption. Use the back-light
instead: Changing the back-light brightness will affect power
consumption, the lower the brightness, the lower the power usage.If Soft Brightness controls an OLED panel, changing the brightness
will affect power consumption, the lower the brightness, the lower the
power usage.### Common use cases and usage scenarios
#### You have a desktop computer
Soft Brightness can be used to control the brightness of all your
attached monitors:- Set _Use backlight control_ to _Off_.
- Set _Monitor(s)_ to _All_.
#### You have a laptop computer with a back-light
You can leave the control of your attached display to the back-light
and use Soft Brightness to control the brightness of external
displays:- Set _Use backlight control_ to _On_.
- Set _Monitor(s)_ to _External_.
- Configure _Built-in monitor_ to your built-in panel's name.
#### You have a laptop computer without a back-light
For example an OLED panel or non-functional back-light. Have
Soft-Brightness control the brightness for all your monitors:- Set _Use backlight control_ to _On_.
- Set _Monitor(s)_ to _All_.
