Quick Install

# Download and extract
curl -LO https://github.com/DonutsDelivery/task-manager-linux/releases/latest/download/task-manager-linux-x86_64.tar.gz
tar xzf task-manager-linux-x86_64.tar.gz
cd task-manager-linux

# Run
./task-manager-linux

Runtime dependencies: GTK4 and libadwaita must be installed on your system. Most modern Linux desktops (GNOME, KDE Plasma 6) include these by default.

Features

• Process Management — View, end, force kill, and reprioritize running processes
• App Grouping — Processes grouped by application using X11 window titles, .desktop files, and /proc/comm
• Performance Monitoring — Real-time CPU, memory, disk, network, and GPU graphs
• GPU Support — NVIDIA GPU monitoring via NVML
• DE Restart — Quick-access button to restart desktop environment components (KDE Plasma, GNOME, XFCE, Cinnamon, MATE)
• Critical Process Protection — Warning dialogs prevent accidentally killing system-critical processes like systemd or kwin
• Global Shortcut — Register Ctrl+Shift+Esc from inside the app (KDE Plasma)

Building from Source

Requires Rust and GTK4/libadwaita development libraries.

# Arch Linux
sudo pacman -S gtk4 libadwaita

# Ubuntu/Debian
sudo apt install libgtk-4-dev libadwaita-1-dev

# Build
cargo build --release

The binary will be at target/release/task-manager-linux.

Keyboard Shortcut

To register Ctrl+Shift+Esc as a global shortcut (KDE Plasma):

1. Launch the app
2. Click the hamburger menu (top right)
3. Click Install Ctrl+Shift+Esc Shortcut
4. Log out and back in

Or run the setup script:

./scripts/setup-shortcut.sh

Tech Stack

• Rust with GTK4-rs and libadwaita
• procfs for process and system data
• nvml-wrapper for NVIDIA GPU monitoring
• x11rb for window title resolution
• flume for async backend-to-UI communication
