# Brightness widget
|

|
|

![Brightness widget](./br-wid-1.png)
|
||
|
|
||
|
This widget represents current brightness level.
|
||
|
|
||
|
## Installation
|
||
|
|
||
|
Firstly you need to get the current brightness level. There are two options:
|
||
|
|
||
|
- using `xbacklight` command (depending on your video card (I guess) it may or may not work)
|
||
|
|
||
|
To check if it works install xbackligth and check if it works:
|
||
|
|
||
|
```bash
|
||
|
sudo apt-get install xbacklight
|
||
|
xbacklight -get
|
||
|
```
|
||
|
|
||
|
If there is no output it means that it doesn't work, but there is a second option:
|
||
|
|
||
|
- using `light` command
|
||
|
|
||
|
Install it from this git repo: [github.com/haikarainen/light](https://github.com/haikarainen/light) and check if it works but running
|
||
|
|
||
|
```bash
|
||
|
git clone https://github.com/haikarainen/light.git && \
|
||
|
cd ./light && \
|
||
|
sudo make && sudo make install \
|
||
|
light -G
|
||
|
49.18
|
||
|
```
|
||
|
Depending on the chosen option change `GET_BRIGHTNESS_CMD` variable in **brightness.lua**.
|
||
|
|
||
|
Then in **rc.lua** add the import on top of the file and then add widget to the wibox:
|
||
|
|
||
|
```lua
|
||
|
require("awesome-wm-widgets.brightness-widget.brightness")
|
||
|
...
|
||
|
-- Add widgets to the wibox
|
||
|
s.mywibox:setup {
|
||
|
...
|
||
|
{ -- Right widgets
|
||
|
...
|
||
|
brightness_widget
|
||
|
```
|
||
|
|
||
|
## Controls
|
||
|
|
||
|
In order to change brightness by shortcuts you can add them to the `globalkeys` table in the **rc.lua**:
|
||
|
|
||
|
```lua
|
||
|
awful.key({ modkey }, ";", function () awful.spawn("light -A 5") end, {description = "increase brightness", group = "custom"}),
|
||
|
awful.key({ modkey, "Shift"}, ";", function () awful.spawn("light -U 5") end, {description = "decrease brightness", group = "custom"}),
|
||
|
```
|
||
|
On laptop you can use `XF86MonBrightnessUp` and `XF86MonBrightnessDown` keys.
