CyberXero Toolkit

The Xero Toolkit, unchained. A GTK4/libadwaita system management application for any Arch-based distribution, not just one.

Built in Rust. Ships with 11 system utility scripts.. Rewrites two feature pages from the ground up. Strips out every distribution lock. And it does all of this while fixing the upstream codebase's ineffecient architecture.

Origin: This is a hard fork of the XeroLinux Toolkit by Synse and DarkZero. The original is a competent tool, if you happen to be running XeroLinux. If you aren't, it refuses to start. CyberXero removes that restriction at the source level, then goes dramatically further: rewriting entire subsystems, adding several features the original never shipped, and delivering a toolkit that treats every Arch-based system as a first class citizen.

What Changed, And How Much

This is not a cosmetic fork. Here is what the numbers look like:

Metric	Original Toolkit	CyberXero Toolkit
Total codebase (Rust + Bash + UI)	13,000 lines	15,200 lines
Rust source	9,749 lines	11,258 lines
Containers & VMs page	290 lines	839 lines (complete rewrite)
Servicing & System Tweaks page	250 lines	1,261 lines (5× expansion)
Biometrics page	136 lines	325 lines (jailbroken + uninstall)
Bundled system scripts	0	11 scripts, 1,828 lines
Supported distributions	1 (XeroLinux)	All Arch-based
Uninstall support for installed tools	Partial	Every single tool
Install/uninstall scripts for the toolkit itself	None	Both included

The original toolkit will not run on your system unless it reads "XeroLinux" from /etc/os-release. the check is deleted from the source. There is no runtime gate. There is no workaround. The code simply isn't there.

Feature Breakdown.

Containers & VMs, Fully Rewritten

The original Containers & VMs page relies on virtualbox-meta and virt-manager-meta, which are XeroLinux-specific metapackages that do not exist on any other distribution. CyberXero replaces every single one with explicit, documented package lists that work everywhere.

What this means in practice:

• VirtualBox now detects your running kernel at install time. Stock linux gets prebuilt host modules. linux-lts gets its own. Any custom kernel (zen, cachyos, hardened, etc.) gets DKMS with auto-detected headers. The original just ran a metapackage and hoped for the best.
• KVM/QEMU installs a complete, explicit package list: qemu-desktop, libvirt, virt-manager, virt-viewer, edk2-ovmf, dnsmasq, iptables-nft, openbsd-netcat, swtpm. It detects and resolves iptables/gnu-netcat conflicts before they break your install. It reads /proc/cpuinfo to write the correct nested virtualization config (kvm-intel vs kvm-amd). It adds you to the libvirt group. It enables libvirtd.service. It ships swtpm for Windows 11 TPM 2.0 compatibility. The original did none of this.
• Every tool (Docker, Podman, VirtualBox, DistroBox, KVM/QEMU, iOS iPA Sideloader) now has a dedicated uninstall button that properly stops services, removes group memberships, and cleans up packages.
• Smart state tracking: install buttons grey out with a checkmark when a tool is already detected, and refresh automatically when you return to the page.

Servicing & System Tweaks 5× Expansion

The original servicing page has 7 functions. CyberXero has 15, including:

• Third-party repo installation: one-click buttons for CachyOS repos, Chaotic-AUR, and the XeroLinux repo (so you can access XeroLinux packages without running XeroLinux).
• Smart mirror updates: auto-detects every installed repository and updates all mirrorlists using rate-mirrors. Supports Arch, CachyOS, Chaotic-AUR, EndeavourOS, Manjaro, RebornOS, and Artix out of the box.
• xPackageManager integration: a forked version with the distro check removed and hardcoded repo references replaced with dynamic detection, works with whatever repos you actually have configured.
• Toolkit self update: checks the upstream commit hash and rebuilds from source when a new version is available.
• Remove Orphaned Packages checks for orphaned packages and presents a list the user can choose to remove some or all of

Multimedia Page Addition

• GPU Screen Recorder with smart repo detection installs from official repos when available, falls back to AUR when not.

Biometrics — Jailbroken Edition

The original ships biometric support that is locked to XeroLinux. CyberXero jailbreaks it:

• Fingerprint authentication builds from a fork that bypasses upstream lockdowns. Full PAM integration. Works with any fprintd-compatible reader.
• Facial recognition (Howdy Qt) is the first fully working integration — CyberXero beat upstream to it by building from source rather than depending on a broken howdy-bin package. Uses howdy-git with correct dependencies.
• Both features ship with install and uninstall buttons — the original has no uninstall path.

11 Bundled System Scripts

The original toolkit calls out to scripts that are packaged separately on XeroLinux scripts that simply don't exist on any other distribution. 10 of these 11 are those XeroLinux packaged utilities, bundled directly into this repo so that every feature they power actually works regardless of what distro you're on. The 11th, cyberxero-theme, is entirely new:

Script	Purpose
upd	Comprehensive system updater: pacman, AUR, Flatpak, Rust toolchain, firmware. Detects if reboot is needed.
xpm	Plymouth theme wizard for Arch Linux
cyberxero-theme	CyberXero desktop theme installer with backup/restore (765 lines)
rddav	Real-Debrid WebDAV automount via rclone + systemd
gcm	Git credential helper wizard
pmpd	Pamac database repair tool
pacup	Pacman.conf updater with automatic backup
keyfix	Pacman keyring and database repair
rpipe	PipeWire restart utility
opr-drv	OpenRazer driver installer with user group setup
getcider	Cider music player installer with GPG key signing

All scripts are installed to /usr/local/bin automatically and removed cleanly by the uninstaller.

Under the Hood

• Async channel migration: the original uses the deprecated glib::MainContext::channel API, which was removed in glib-rs 0.19. CyberXero migrates to async_channel, putting system dependency checks on a background thread. The result is a responsive UI during startup, the original hitches noticeably, and it got worse the more features I added, so this rewrite was much needed.
• Window presentation fix: the main window now only presents after the full UI is assembled, preventing the visible resize flash that plagued tiling window manager/krohnkite users.
• Smart package detection: Falcond and other tools check if packages exist in your configured repos before falling back to AUR, using pacman for repo packages and your AUR helper only when necessary.

Supported Distributions

Any Arch-based distribution, including but not limited to:

Arch Linux · EndeavourOS · CachyOS · Garuda Linux · Manjaro · ArcoLinux · Artix · RebornOS

If it has pacman, it runs.

Requirements

• AUR helper — Paru or Yay (the installer will offer to set one up if missing)
• Flatpak — optional but recommended for OBS Studio and some multimedia tools

Installation

One-liner:

rm -rf /tmp/xero-toolkit-open && git clone https://github.com/MurderFromMars/CyberXero-Toolkit.git /tmp/xero-toolkit-open && sh /tmp/xero-toolkit-open/install.sh && rm -rf /tmp/xero-toolkit-open

Manual:

git clone https://github.com/MurderFromMars/CyberXero-Toolkit.git
cd CyberXero-Toolkit
./install.sh

The installer handles everything: dependency resolution, AUR helper setup, Rust compilation, binary installation to /opt/xero-toolkit, desktop entry creation, icon registration, and deployment of all 11 system scripts.

Uninstallation

cd CyberXero-Toolkit
./uninstall.sh

Removes binaries, symlinks, desktop entries, icons, all bundled scripts, and user autostart entries. Clean removal — nothing left behind.

Build Dependencies

Installed automatically by install.sh:

rust · cargo · pkgconf · gtk4 · glib2 · libadwaita · vte4 · flatpak · polkit · base-devel · scx-scheds
