CachyOS XPS Post-Install Fixes

This is a CachyOS-first post-install toolkit for Dell XPS Panther Lake systems. It ports the useful Omarchy hardware enablement work without running Omarchy's full installer or replacing CachyOS system ownership.

Usage

Audit only:

cd ~/cacheOS-xps-fixes/cachyos-xps-postinstall
./run.sh audit

Full post-install pass on CachyOS:

./install.sh --yes

Apply without the initial pacman -Syu:

./run.sh apply --yes

Preview writes and commands:

./run.sh install --dry-run

Modules

• 00-preflight: CachyOS, Dell XPS, Panther Lake, bootloader, kernel, Wi-Fi, touchpad, and camera detection.
• 10-baseline-packages: firmware, audio, PipeWire, DKMS, GStreamer, fwupd, Bluetooth, and matching kernel headers.
• 20-bootloader-fred: adds fred=on for Panther Lake through the detected bootloader.
• 30-intel-power-media: Intel media packages, thermald, power-profiles-daemon, optional intel-lpmd.
• 40-wifi7-eht: disables Intel BE200/BE211 Wi-Fi 7 EHT on Dell XPS Panther Lake.
• 50-haptic-touchpad: Synaptics XPS haptic touchpad daemon, service, udev rule, and reset helper.
• 60-mic-mute-led: Dell XPS mic mute helper that syncs PipeWire mute with ALSA capture state.
• 70-ipu7-camera: builds Omarchy IPU7 camera packages when requested, then installs runtime camera glue.
• 80-firmware: lists LVFS/fwupd updates; only applies firmware with --firmware-update.

Camera Build

install mode automatically enables camera build when IPU7/OV08X40 hardware is detected. For apply mode, pass:

./run.sh apply --yes --build-camera

The camera build must run as a normal user, not root. The script uses sudo only for package installation and system file writes.

Safety

• The toolkit refuses apply and install on non-CachyOS systems.
• Existing files are backed up under /var/backups/cachyos-xps-fixes.
• Firmware updates are listed by default, not applied.
• Bootloader changes go through systemd-boot, GRUB, or Limine regeneration paths.
