# LiQuid Screen Dim
|
|
A simple utility which dims your screen. It saves the previous brightness too, so you can restore to the point before dimming.
|
|
|
|
This is useful if you are running a standalone screen locking setup like swayidle/swaylock. Check out [my configuration files](https://git.reekynet.com/ReekyMarko/dotfiles/src/branch/master/home/Scripts/swayidle.sh) for an example use case.
|
|
|
|
## Usage
|
|
```nosyntax
|
|
USAGE:
|
|
lqsd [FLAGS] [OPTIONS]
|
|
|
|
FLAGS:
|
|
-d, --dim Dims the screen to idle level set in configuration
|
|
-r, --resume Sets the backlight to the value it was before dimming
|
|
--copy-config Copies the default config file to $XDG_CONFIG_HOME/lqsd
|
|
-h, --help Prints help information
|
|
-V, --version Prints version information
|
|
|
|
OPTIONS:
|
|
--config <FILE> Sets a custom config file
|
|
```
|
|
The configuration file resides at `~/.config/lqsd/config.toml`. To copy the default configuration file in place, you can use `--copy-config`.
|
|
|
|
In the configuration file you can set the following values:
|
|
|
|
| Key | Explanation | Default |
|
|
| ---------------- | -------------------------------------------------------------------------------------------- | :-----------------: |
|
|
| resume_file | The location where the previous brightness is saved | /tmp/lqsd-resume |
|
|
| idle_level | The minimum brightness that will be dimmed to. Can be a value between 0-100 | 0 |
|
|
| dim_speed | This sets the "sleep time" between each backlight command. It's in milliseconds | 50 |
|
|
| resume_speed | Same as dim_speed, but for the resume operation `-r` | 25 |
|

## Installation
|
|
|
|
### Dependencies
|
|
The only external dependency is [light](https://github.com/haikarainen/light).
|
|
|
|
### Building
|
|
Clone this repository and run `cargo build --release` inside the project to compile a static binary.
|
|
|
|
### Arch Linux
|
|
So far, I have only packaged this for Arch Linux. Packages are in [AUR](https://aur.archlinux.org/packages/?K=lqsd).
|
|
|
|
To install it, use your favorite AUR helper, yay for example:
|
|
```nosyntax
|
|
yay -S lqsd
|
|
```
|
|
Select if you want to [1] build from source [2] install a precompiled binary:
|
|
```nosyntax
|
|
:: There are 2 providers available for lqsd:
|
|
:: Repository AUR
|
|
1) lqsd 2) lqsd-bin
|
|
|
|
Enter a number (default=1):
|
|
```
|
|
|
|
## Releases
|
|
Release notes can be found in [GitHub](https://github.com/ReekyMarko/lqsd/releases) (Gitea does not support editing tags yet).
|
|
|
|
Prebuilt binaries, their checksums and signatures can also be found there.
|
|
|
|
## Why Rust?
|
|
I wanted start a small project to learn Rust. Before lqsd, I was using [this script](https://github.com/Bonnee/dotfiles/blob/wayland/scripts/bin/dim.sh) and figured, why not rewrite it in Rust.
