When using a window manager, wallpapers is a part of it. Maybe you want a menu to choose wallpaper, shuffling, automatically change them, match keyboard backlight to wallpaper's best color, setting next/previous. If so, this is what you're looking for! Auto walls is a Linux wallpaper system for any window manager: flexible and customizable, written entirely in Python.

• Automatically sets random wallpaper every n minutes.
• Sets keyboard backlight color based on the wallpaper.
• Provides scripts for setting previous and next wallpapers.
• Provides Rofi menu script to select wallpaper.

A collection of scripts including a main script launched at startup, scripts to set previous and next wallpapers, a script to run a Rofi menu with wallpaper options, and adaptive keyboard backlight module. If change_backlight in the config is set to true, the backlight changes based on the dominant color from the wallpaper image. Initially used with swww and rogauracore (ASUS ROG laptops) to changie wallpaper and keyboard backlight color, but can be configured to use with any other cli tool

• swww: Wayland wallpapers tool.
• rogauracore: CLI tool for changing keyboard color on ASUS ROG laptops.
• rofi: Required for the wallpapers menu.
• ffmpeg: For thumbnails generation

pip install numpy Pillow scikit-learn

sudo pacman -S python-numpy python-scikit-learn python-pillow

Clone this repository and execute the main script (auto_walls.py) on startup with your window manager. It will change wallpapers at specified intervals and provide functions for dynamic backlight color and setting next/previous wallpapers. Bind set_next.py and set_previous.py for controlling wallpaper changes and rofi_selector.py for toggling the wallpaper menu.

exec-once = python3 ~/your/path/to/auto_walls/auto_walls.py

bind = ALT, F5,       exec, python3 ~/your/path/to/auto_walls/set_next.py
bind = ALT SHIFT, F5, exec, python3 ~/your/path/to/auto_walls/set_prev.py

bind = SUPER, Y, exec, python3 ~/your/path/to/auto_walls/rofi_selector.py

Note: It's strongly recommended to run auto_walls.py from the terminal for the first time.

After the first run of auto_walls.py, the following config will be generated at ~/.config/auto_walls/config.json by default:

{
    "interval": 30,
    "wallpapers_dir": "~/Pictures",
    "wallpapers_cli": "swww img <picture>",
    "keyboard_cli": "rogauracore single_static <color>",
    "keyboard_transition_cli": "rogauracore single_breathing <prev> <color> 3",
    "change_backlight": false,
    "transition_duration": 1.1,
