🧊 Fedora-Specific Features

Fedora users benefit from a streamlined, fully native NVIDIA and multimedia setup:

• ⚙️ Automatic NVIDIA driver installation
  Installs the latest available akmod-nvidia package with CUDA support, ensuring your GPU drivers are rebuilt automatically across kernel updates.

• 🧩 Open kernel module for RTX 4000+
  For RTX 4000 series and newer GPUs, Fedora needs a build macro to enable the open NVIDIA kernel module before installing the driver.
  The script sets this automatically. Manually, you can run:

  # Set open kernel module macro (one-time step for RTX 4000+)
  sudo sh -c 'echo "%_with_kmod_nvidia_open 1" > /etc/rpm/macros.nvidia-kmod'

  After this is set, akmods will build using the open NVIDIA kernel module.

• 🎬 Full multimedia stack
  Installs gstreamer1-plugins-*, ffmpeg, and related codecs to unlock playback support in all major apps.

• 🧱 Archive utilities
  Installs common compression tools such as 7zip, unrar, and file-roller.

• 🌐 Flatpak + Flathub
  Ensures Flatpak is enabled and Flathub is configured as the primary source for desktop applications.

Together, these ensure a smooth Fedora experience with open driver support, media acceleration, and production-ready utilities.

🧊 Arch Cinnamon Enhancements

When the script detects Arch Linux running the Cinnamon desktop, it layers on a tailored experience to bring Mint-like polish to the stock Arch install:

• 🧰 Desktop essentials preinstalled — ristretto, papers, gedit, gnome-calculator, papirus-icon-theme, file-roller, and nemo-fileroller are installed in one shot so the desktop feels ready immediately.
• 🗜️ Clean file manager integration — automatically removes engrampa to avoid duplicate archive handlers and lets nemo-fileroller take over compression/extraction duties.
• 🎨 Mint artwork bundle (AUR) — builds the large mint-artwork package via paru with a quiet spinner + log file so the terminal stays tidy while themes, icons, sounds, and LightDM slick greeter assets install.
• 🔐 LightDM configured automatically — once the artwork lands, /etc/lightdm/lightdm.conf is patched to use lightdm-slick-greeter, matching the Mint visual style right at login.
• 🎬 Cinnamon media stack — installs GNOME Showtime plus gstreamer, gstreamer-vaapi, and the full GST plugin families, then adds ffmpegthumbnailer for rich file previews.

These additions only run on Arch+Cinnamon systems; other Arch desktops continue to receive the lean, DE-aware defaults.

🧊 Linux Mint-Specific Features

Linux Mint 22+ systems are prepped for gaming and creative work with minimal manual intervention:

• 🧱 Enables 32-bit (i386) architecture and updates immediately
  Adds the i386 architecture if missing, then runs a full apt update && apt upgrade -y so your base system is current before drivers land.

• ⚙️ Installs NVIDIA drivers via the graphics-drivers PPA
  Adds the official Graphics Drivers PPA, installs linux-headers-$(uname -r), build-essential, and dkms, then picks the right driver:

  • RTX 4000/5000 → latest nvidia-driver-###-open
  • RTX 3000 and older → latest nvidia-driver-###
    Falls back to ubuntu-drivers autoinstall if detection ever fails.

• 💾 Optimizes memory and filesystem tooling
  Sets vm.swappiness=10 (runtime + persistent) so RAM is preferred over swap, then installs unzip, ntfs-3g, p7zip, curl, bzip2, tar, exfat-fuse, wget, unrar, and gstreamer1.0-vaapi.

• 🎬 Maximizes multimedia support
  Ensures the mint-meta-codecs bundle is installed so H.264, HEVC, and other formats play instantly.

• 🚀 Enables NVIDIA VAAPI playback
  Installs nvidia-vaapi-driver so compatible players can tap the GPU for decoding workloads.

• 📺 Installs GNOME Showtime from Flathub
  Verifies Flatpak is present, then installs org.gnome.Showtime for a modern video playback experience.

---

🧊 Ubuntu-Specific Features

Ubuntu users get a clean, optimized, and GPU-ready setup automatically:

• 🧹 Removes Snap packages completely
  The script purges Snap and related services using the included snap-to-flatpak.sh helper.

• 🔄 Switches to Flatpak
  After Snap removal, Flathub is added as the default Flatpak remote.

• ⚙️ Installs NVIDIA drivers intelligently
  The script detects your GPU generation and installs the latest compatible driver:

  • For RTX 4000 series and newer → Installs the latest available NVIDIA Open Kernel Module driver (e.g., nvidia-driver-580-open).
  • For RTX 3000 series and earlier → Installs the latest proprietary NVIDIA driver automatically.
  • If detection fails for any reason, it falls back to:

  sudo ubuntu-drivers autoinstall

• 🌐 Restores Firefox from Mozilla’s official repository (no PPA)
  Removing Snap removes the Snap-based Firefox, so the script reinstalls Firefox from Mozilla’s official APT repository (with GPG + pinning) to get a native .deb:

  ✅ Verified GPG Key Fingerprint:

  35BAA0B33E9EB396F59CA838C0BA5CE6DC6315A3
  

Together, this ensures a Flatpak-friendly Ubuntu with a native, GPU-optimized system and up-to-date Firefox.

🧊 Debian-Specific Features

Debian 13 (Trixie) systems get a modernized desktop with sane defaults out of the box:

• 🔄 Full update + repo refresh — runs apt update && apt full-upgrade -y, backs up and comments your stock /etc/apt/sources.list, then writes the Trixie main contrib non-free non-free-firmware sources and refreshes apt.
• 📦 extrepo enabled with contrib/non-free — installs extrepo and uncomments contrib and non-free in /etc/extrepo/config.yaml so you can easily add third-party repos.
• 🌀 Backports kernel/firmware refresh — adds /etc/apt/sources.list.d/trixie-backports.list, refreshes apt, and installs backported linux-image-amd64, linux-headers-amd64, and firmware-misc-nonfree.
• ⚙️ NVIDIA headers + drivers (open or proprietary) — installs linux-headers-$(uname -r) and build-essential, adds the NVIDIA CUDA repo keyring (wget https://developer.download.nvidia.com/compute/cuda/repos/debian12/x86_64/cuda-keyring_1.1-1_all.deb && sudo dpkg -i cuda-keyring_1.1-1_all.deb), runs sudo apt update, then installs nvidia-open for RTX 4000/5000 series or cuda-drivers for older GPUs.
• 🎬 Hardware acceleration — adds nvidia-vaapi-driver for GPU-backed decoding.
• 🌐 Flatpak + Flathub + desktop tooling — installs Flatpak, adds Flathub, and installs Flatseal + Bazaar for managing and browsing Flatpaks.
• 🗜️ Essential tools + codecs + fonts — installs CLI essentials (git, curl, wget, fastfetch, htop, ffmpeg, build tools, archive utils, NTFS support), Microsoft core fonts, and Noto (Latin + CJK).
• 🧩 GNOME niceties (GNOME desktops only) — installs GNOME Tweaks, GNOME Shell Extension Manager, and the GNOME Software Flatpak plugin.

These steps aim to keep Debian close to upstream while enabling common multimedia, GPU, and desktop conveniences with minimal manual effort.

🧮 Usage

git clone https://github.com/ArcticLatent/post-linux.git
cd post-linux
chmod +x post_linux.sh
./post_linux.sh

Follow the interactive prompts to choose your distro and GPU series.

Debian note: Debian 13 user accounts do not have sudo by default. Run the script as root with:

su -c "bash <(wget -qO- https://raw.githubusercontent.com/ArcticLatent/post-linux/refs/heads/main/post_linux.sh)"

---

♻️ Updating the Script

• ./post_linux.sh --check-update — see if a newer release is available.
• ./post_linux.sh --update — download the latest copy and rerun automatically.
• ./post_linux.sh --version — print the currently installed version.
• Set POST_LINUX_SOURCE to point at an alternate raw URL if you host your own fork.

The script compares its local SCRIPT_VERSION against the remote source and offers to self-update before running the main workflow.
