Set a different wallpaper for the background of each Sway workspace
|
||||
|
||||
## Usage
|
||||
|
||||
$ multibg-sway <WALLPAPER_DIR>
|
||||
|
||||
Wallpapers should be arranged in the following directory structure:
|
||||
|
||||
wallpaper_dir/output/workspace_name.{jpg|png|...}
|
||||
|
||||
Eg.
|
||||
|
||||
~/my_wallpapers/HDMI-A-1/1.jpg
|
||||
|
||||
In more detail:
|
||||
|
||||
- **wallpaper_dir**: A directory, this will be the argument for the multibg-sway command
|
||||
|
||||
- **output**: A directory with the same name as a sway output eg. eDP-1, HDMI-A-1
|
||||
- If one has multiple outputs with the same resolution this can be a symlink to the directory of the other output.
|
||||
- To get the name of current outputs from sway one may run:
|
||||
|
||||
$ swaymsg -t get_outputs
|
||||
|
||||
- **workspace_name**: The name of the sway workspace, by sway defaults: 1, 2, 3, ..., 10
|
||||
- Can be a manually defined workspace name (eg. in sway config), but renaming workspaces while multibg_sway is running is not supported currently
|
||||
- Can define a fallback wallpaper with the special name: _default
|
||||
- Can be a symlink to use a wallpaper image for multiple workspaces
|
||||
|
||||
Wallpaper images are not resized by multibg-sway currently, so they should have the same resolution as the output
|
||||
|
||||
### Example:
|
||||
|
||||
For one having a laptop with a built-in display eDP-1 and an external monitor HDMI-A-1, wallpapers can be arranged such as:
|
||||
|
||||
~/my_wallpapers
|
||||
├─ eDP-1
|
||||
│ ├─ _default.jpg
|
||||
│ ├─ 1.jpg
|
||||
│ ├─ 2.png
|
||||
│ └─ browser.jpg
|
||||
└─ HDMI-A-1
|
||||
├─ 1.jpg
|
||||
└─ 3.png
|
||||
|
||||
Then start multibg_sway:
|
||||
|
||||
$ multibg-sway ~/my_wallpapers
|
||||
|
||||
It is recommended to edit the wallpaper images in a dedicated image editor. Nevertheless the contrast and brightness might be adjusted here:
|
||||
|
||||
$ multibg-sway --contrast=-25 --brightness=-60 ~/my_wallpapers
|
||||
|
||||
## Installation
|
||||
- With Rust toolchain:
|
||||
- For Arch Linux from AUR:
|
||||
|
||||
## Alternatives
|
||||
- swaybg
|
||||
- swww
|
||||
- mpvpaper
|
||||
- oguri
