Single-script builder (nosignal.sh) that turns a stock Arch Linux ISO into a fully-offline installer for a themed Hyprland + caelestia (Quickshell) desktop: matching SDDM greeter, Btrfs/Limine bootable snapshots, chwd-style GPU detection, and a curated "os updates" layer (keybind cheatsheet, settings panels, system polish, on-box management skill). See README.md. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# The Additions page ships on every install and GPUs differ (AMD / Intel /
|
|
# NVIDIA, any mix — e.g. AMD discrete + Intel iGPU), so the
|
|
# encoder runtime packages are DETECTED per machine, not hardcoded.
|
|
#
|
|
# obs-extras.sh check exit 0 only if OBS + everything this box's GPUs
|
|
# need is installed (drives the Additions row state)
|
|
# obs-extras.sh install install OBS + the detected encoder runtimes
|
|
#
|
|
# Per-vendor encoder support on Arch:
|
|
# AMD — VAAPI (H.264/HEVC/AV1) ships inside mesa (base system): no extra
|
|
# package since the libva-mesa-driver merge.
|
|
# Intel — intel-media-driver (VAAPI) + vpl-gpu-rt (QuickSync/QSV runtime).
|
|
# NVIDIA — NVENC comes with the proprietary driver (nvidia-utils or a
|
|
# legacy branch). Deliberately NOT auto-installed here: the driver
|
|
# branch is a system-level decision (see gaming-enablement's
|
|
# NVIDIA notes) — we print a pointer instead.
