# backlight
Program to manipulate screen brightness on Linux using sysfs.
```
backlight. Simple program to control your backlights.
Usage:
backlight ls Lists all devices and their values
backlight set Sets the brightness of a device to a specific value
backlight dec Decreases the brightness of a device by a specific value
backlight inc Increases the brightness of a device by a specific value
backlight help Displays this help message :)
```
## Install
For x64 you can download and install the released binary with the following script.
```bash
wget https://github.com/Tethik/backlight/releases/download/1.0.0/backlight.0-x64
chmod +x backlight.0-x64
sudo mv backlight.0-x64 /usr/local/bin/backlight
sudo setcap cap_dac_override+ep /usr/local/bin/backlight
```
### Build from source
Requires that you have golang installed.
```
git clone https://github.com/Tethik/backlight
make
sudo make install
```
_Why sudo?_ To allow the program access to sysfs from a normal user the install script sets `cap_dac_override`.
### i3 configuration
I originally built this for my own i3 setup. The following is the configuration I use to
bind the brightness keys on my laptop to run this backlight program.
```
# Sreen brightness controls
bindsym XF86MonBrightnessUp exec backlight inc intel_backlight 50
bindsym XF86MonBrightnessDown exec backlight dec intel_backlight 50
```
