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>

# gaming-session-switch — DeckShift-compatible session-switch helper, patched
|
|
# for password-at-boot. Same path + same {gaming|desktop} interface as
|
|
# DeckShift's original (the existing sudoers rule and switch-to-gaming /
|
|
# switch-to-desktop / os-session-select callers all keep working).
|
|
#
|
|
# DeckShift's original keeps a PERMANENT SDDM autologin drop-in and only flips
|
|
# its Session= line, so the machine never shows a password screen. This version
|
|
# writes the drop-in fresh on every switch and arms a one-shot marker in /run;
|
|
# sddm-autologin-gate (ExecStartPre on sddm.service) consumes the marker so the
|
|
# autologin applies to THAT restart only. Cold boots, crashes, and manual SDDM
|
|
# restarts find no marker and get the normal password greeter.
