Post-install scripts for Debian 13 (Trixie) with GNOME. Two independent tools in one repo:

• battery-optimizer/ — Cuts laptop power draw from ~21W to ~8W on battery (Intel + NVIDIA)
• desktop-setup/ — Full GNOME desktop customization (themes, extensions, terminal, etc.)

Each one works standalone. Use both or just the one you need.

Intelligent power management for laptops with Intel hybrid CPUs and NVIDIA dedicated GPUs. Automatically switches between performance (AC) and power-saving (battery) profiles.

Result: 2-3h battery life becomes 6-7h.

AC plugged in                    Battery (unplugged)
─────────────                    ───────────────────
All 16 threads active            8 threads only (P-cores)
NVIDIA loaded + D3 idle          NVIDIA completely removed from PCI bus
CPU boost ON                     CPU boost OFF, max 50%
Performance profile              Low-power profile

The switch is automatic via udev rules — plug/unplug the charger and it applies instantly. A systemd service applies the correct profile at boot.

cd battery-optimizer
sudo ./install.sh           # Interactive — choose what to enable
sudo ./install.sh --status  # Check current state
sudo ./install.sh --remove  # Uninstall everything

• Debian 13+ (Trixie) with GNOME/Wayland
• Intel 12th-14th gen hybrid CPUs (P-cores + E-cores)
• NVIDIA RTX 3000/4000 series with proprietary drivers
• Should work on Ubuntu 24.04+ and derivatives with minor adjustments

If something goes wrong:

sudo battery-optimizer-recover.sh   # Restore all cores + NVIDIA

Or from TTY (Ctrl+Alt+F3):

# Re-enable all CPU cores
for i in $(seq 1 15); do echo 1 > /sys/devices/system/cpu/cpu$i/online; done

# Remove NVIDIA blacklist and reload
rm /etc/modprobe.d/zz-nvidia-blacklist.conf
modprobe -i nvidia

Full GNOME desktop customization in one script. Modular — pick what you want.

cd desktop-setup
./setup.sh              # Interactive — choose modules
./setup.sh --all        # Install everything
./setup.sh --status     # See what's installed
./setup.sh --remove     # Uninstall customizations

The script is designed to be forked and modified:

• Wallpaper: Replace assets/wallpapers/macWallpaper.jpg with yours
• GNOME config: Export your own with dconf dump / > configs/gnome/dconf-full.ini
• Kitty config: Edit configs/kitty/kitty.conf
• TLP config: Edit configs/tlp/01-battery-optimized.conf
• Conky theme: Swap configs/conky/Mimosa/ with any Conky theme
• Extensions list: Edit the EXTENSIONS array in setup.sh

Both scripts are idempotent. Running them again will:

• Skip already installed components
• Update configs to latest version
• Not break existing customizations
