Auto walls

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.

Features

• 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.

About

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 a keyboard module. If change_backlight in the config is set to true, the backlight changes based on the dominant color from the wallpaper image. Initially designed for swww and rogauracore (ASUS ROG laptops) due to their CLI interfaces for changing wallpaper and keyboard backlight color, but adaptable to any other CLI tools for similar tasks.

Default Requirements

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

Usage

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.

Example on Hyprland:

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.
