This project provides a collection of visual asset packs and automated shell scripts for customizing the appearance of the GRUB2 bootloader on Linux systems. It functions as a complete theme management system, enabling users to install, remove, and select from multiple style variants that change the boot menu's colors, fonts, icons, and layout.
The toolset includes dedicated utilities for adjusting the GRUB2 framebuffer resolution to match the monitor's native display, ensuring graphics are properly scaled and aligned. It also offers a background manager that replaces the default boot menu background with a user-supplied image, automatically scaling it to the configured resolution. The installation and removal processes are handled through idempotent shell scripts that modify configuration files and map assets into the GRUB2 theme directory structure.
The project supports resolution-aware asset scaling, configuration file patching, and variant-based theme selection through command-line flags. It provides commands to apply, generate, install, remove, and configure themes, including the ability to set custom backgrounds and match display resolutions across standard, high-DPI, and ultrawide formats.
