Hi everyone,

I wanted to share a project I’ve been building and refining on my own gaming laptop (ASUS ROG M16, i7-11800H, RTX 3050 Ti) running CachyOS: cachy-gnome-tweaks.

It’s an open-source, modular, interactive installation and optimization suite designed specifically for CachyOS/Arch GNOME environments to streamline post-install setup, optimize compiler performance, and fix common gaming laptop issues out of the box.

• GitHub Repository: https://github.com/esfingex/cachy-gnome-tweaks

**What does it do?

1. Laptop & Thermal Tuning (ASUS ROG/TUF & Intel CPUs) - New**

• Integrates asusctl and supergfxctl for physical power profiles (Silent, Balanced, Turbo), custom fan curves, and dGPU power-management.

• Automatically clones and installs chikobara’s GPU Switcher GNOME Shell extension (gpu-switcher-supergfxctl) so you can toggle between Integrated-only, Hybrid, or Dedicated GPU modes directly from the GNOME Quick Settings panel.

• Automates Intel’s thermald to pro-actively regulate CPU energy/voltages, maintaining consistent clock speeds and preventing sudden thermal throttling stutters under heavy load (like Switch emulation).

• Fixes a known systemd sandboxing bug by automatically managing the /etc/asusd namespace folder on fresh setups.

2. NVIDIA Wayland Suspend Fix

• Resolves the notorious Wayland lockups and screen corruption on Optimus laptops when closing and opening the lid.

• Automatically configures options nvidia NVreg_PreserveVideoMemoryAllocations=1 in /etc/modprobe.d/ and enables the necessary systemd services (nvidia-suspend, nvidia-hibernate, nvidia-resume) to save/restore VRAM state natively.

3. Lightning-Fast Source Compilations (RAM-disk makepkg)

• Optimizes /etc/makepkg.conf to compile AUR or source packages directly in system memory (BUILDDIR=/tmp/makepkg using tmpfs).

• Drastically reduces compilation times, bypasses SSD I/O latency, and protects physical SSD lifespans from write exhaustion during heavy builds.

• Idempotent checks ensure it never corrupts pre-configured compiler optimization flags.

4. Clean Wine & Gaming Core (No Bloatware)

• Installs an optimized, conflict-free wine-cachyos runtime and 32/64-bit multilib graphics/audio dependencies.

• Integrates protontricks, protonup-qt, and the GNOME GameMode top bar status indicator extension without installing heavy launchers (no Lutris/Heroic bloat).

5. Desktop & App Bundles

• Standardizes high-fidelity audio Bluetooth codecs (LDAC, aptX), system file-watcher limits (inotify), snappers for BTRFS rollback, KVM/QEMU virtualization tools, Docker stack with NVIDIA CUDA container toolkit, and essential system utilities like GParted and archive managers.
