Overview

Soplos GRUB Editor is an advanced graphical tool for configuring the GRUB2 bootloader. It allows you to customize boot entries, themes, and kernel parameters without editing complex configuration files.

Compatible with XFCE, Plasma, and GNOME, it provides a safe and easy way to manage your boot options, including automatic backups to prevent configuration errors.

Key Features

  • Dynamic Environment Adaptation: Advanced detection for Wayland/X11 and DEs, adapting themes dynamically even when elevated.
  • Robust Theme Management: Install GRUB themes from archives and proactively prevent system script conflicts.
  • Hierarchical Boot Entries: Full support for nested submenus and auto-detection of system and recovery entries.
  • Custom Fonts & Backgrounds: Convert TrueType fonts to PF2 format and safely configure custom background colors.
  • Secure System Operations: Safe pkexec elevation, silent background syncs, and intelligent GRUB cache cleanup.
  • General Configuration: Manage timeout, default OS entry, resolutions, and advanced kernel parameters easily.
  • Submenu Toggle: Enable or disable GRUB submenus via GRUB_DISABLE_SUBMENU directly from Advanced Settings.
  • UUID Option: Checkbox to enable or disable GRUB_DISABLE_LINUX_UUID for systems that require device path boot entries.
  • Live Color Sync: Color picker buttons reflect the actual GRUB_COLOR_NORMAL and GRUB_COLOR_HIGHLIGHT values read directly from the GRUB configuration.
  • Smart Theme Preview: Automatically detects theme preview images (preview.png, preview.jpg, background.png/jpg) for accurate visual feedback before applying.
