Installs the Kyber community multiplayer launcher (simonlinuxcraft/kyber- linuxport-unofficial) via the setup.sh wizard. Handles glibc check, bwrap/ userns fix, GitHub release fetch, desktop entry, and bin symlink. Warns on Intel integrated graphics and links to Sunshine as the streaming alternative.

# services/kyber-launcher.sh — Kyber Launcher (native Linux AppImage) for SWBF2 (2017).
|
|
# Part of the modular post-install system (sourced by setup.sh).
|
|
#
|
|
# Kyber is the community multiplayer client for Star Wars Battlefront II (2017)
|
|
# after EA shut down official servers in 2022. It went open-source (GPL) in
|
|
# January 2026. This installs the native Linux AppImage port.
|
|
#
|
|
# Repo: https://github.com/simonlinuxcraft/kyber-linuxport-unofficial
|
|
#
|
|
# ── Requirements ──────────────────────────────────────────────────────────────
|
|
# - SWBF2 (Steam AppID 1237950) installed via Steam on this machine
|
|
# - glibc 2.38+ (Ubuntu/Mint 24.04+, Fedora 38+, SteamOS 3.7+)
|
|
# Linux Mint: Mint 21.x uses Ubuntu 22.04 base (glibc 2.35 — too old).
|
|
# Mint 22.x uses Ubuntu 24.04 base (glibc 2.39 — works).
|
|
# - A real discrete GPU with Vulkan drivers (NVIDIA or AMD recommended)
|
|
# Intel Iris Xe (integrated) is not supported by the Kyber Linux port.
|
|
# - EA account (free) that owns SWBF2
|
|
#
|
|
# ── How to play ───────────────────────────────────────────────────────────────
|
|
# 1. Open Steam (must be running; do NOT click Play on SWBF2)
|
|
# 2. Launch Kyber (kyber command or app menu)
|
|
# 3. Join a server (HOME) or host one (HOST)
|
|
# 4. Kyber/Maxima launches SWBF2 via its own bundled GE-Proton (~1-3 min)
|
|
# 5. If the SWBF2 window appears but won't focus: press Alt+Tab or click it
|
|
#
|
|
# ── bwrap / unprivileged user namespaces ──────────────────────────────────────
|
|
# Ubuntu/Mint 24.04 restricts these by default. This installer fixes it
|
|
# automatically when run with sudo (required for setup.sh anyway).
|
|
# Without the fix: bwrap: setting up uid map: Permission denied
|
|
|
|
# ── Standalone bootstrap ──────────────────────────────────────────────────────
