- GPU detection rewritten: xe-driver-only, bus-based iGPU/dGPU classification, generation tagging (alchemist/battlemage/xe2/xe3/other) for gen-specific workarounds - Selection ranks dGPU+display > dGPU > iGPU+display > iGPU - Removed: MESA MANAGEMENT and MESA-GIT REBUILD sections, USE_MESA_GIT config option, cleanup_on_exit trap (was only relevant during mesa swap) - Added: STEAM FIRST-RUN BOOTSTRAP — interactive Steam login before Gaming Mode - Added: is_omarchy() helper - Gen-specific wrapper env: INTEL_DEBUG=norbc + ANV_QUEUE_THREAD_DISABLE=1 only on Alchemist - README: refreshed support matrix, removed mesa-git/recovery sections, documented gen-aware workarounds

# ARCGames - Gaming Mode Installer for Intel Arc GPUs
|
|
# Version: 1.6.0
|
|
#
|
|
# Description:
|
|
# Sets up a SteamOS-like gaming experience on Arch Linux with Hyprland.
|
|
# Supports Intel Arc discrete GPUs (Alchemist DG2, Battlemage) and modern
|
|
# Intel Arc-branded iGPUs (Lunar Lake Xe2, Panther Lake Xe3).
|
|
#
|
|
# Features:
|
|
# - Steam and gaming dependencies installation
|
|
# - Mesa-git or stable Mesa driver selection
|
|
# - Gamescope session switching (Hyprland <-> Gaming Mode)
|
|
# - Performance tuning (GPU, audio, memory)
|
|
# - External Steam library auto-mounting
|
|
#
|
|
# Usage:
|
|
# ./ARCGames_install.sh [--help|--version]
|
|
#
|
|
# Keybinds (after installation):
|
|
# Super+Shift+S - Switch to Gaming Mode (from Hyprland)
|
|
# Super+Shift+R - Return to Desktop (from Gaming Mode)
|
|
