My Linux Task Manager

A modern, fast, and lightweight Task Manager for Linux, built natively with C++ and GTK3. Inspired by the sleek design of modern system monitors, this tool provides an elegant interface for managing processes, monitoring system performance, and controlling systemd services.

🌟 Features

• Process Management: View all running processes with their CPU & Memory usage. Uses dynamic color highlighting (green for low usage, yellow/orange for medium, red for heavy usage).
• Interactive Performance Graphs:
  • Beautiful real-time line charts drawn natively with Cairo.
  • Monitors global CPU utilization across all cores.
  • Detailed Memory layout (In Use, Available, Cached, Swap).
• Hardware Details: Displays RAM Speed (MHz), Slots used, Type (DDR4/5), and Form Factor directly in the GUI (requires root).
• Service Manager: Seamlessly view, start, stop, and restart systemd background services without touching the terminal.
• Smart Search: Filter processes and services instantly by simply typing anywhere on the screen (no need to click the search bar!).
• Modern UI: Full Dark Mode support and elegant rounded corners perfectly integrated with modern Linux Desktop Environments (Cinnamon, GNOME). All graphical assets are embedded into a single portable binary.

🛠️ Prerequisites

To compile and run this project, you will need the following installed on your system:

• GCC / G++ (supporting C++17)
• CMake (>= 3.10)
• pkg-config
• GTK+ 3.0 development files (libgtk-3-dev / gtk3)
• dmidecode (Optional, but highly recommended for reading RAM hardware details)
• polkit (Optional, for seamless GUI root access via Start Menu)

Installation on Arch Linux / Manjaro

sudo pacman -S base-devel cmake pkgconf gtk3 dmidecode polkit

Installation on Ubuntu / Debian

sudo apt install build-essential cmake pkg-config libgtk-3-dev dmidecode policykit-1

🚀 Building the App

This project uses CMake for an easy, out-of-source build configuration.

git clone https://github.com/ItsMe-RiiK/MyTaskManager.git
cd MyTaskManager

# Generate build files
cmake -B build

# Compile the application
cmake --build build

💻 System-Wide Installation (Recommended)

Because Linux's security model protects deep hardware information (like RAM Speed or Motherboard slots) and the ability to start/stop system services, this application is best run as Root.

We provide a seamless system-wide installation that installs a secure Polkit wrapper (run_taskmanager). This securely elevates privileges while preserving your current $DISPLAY and graphical settings, ensuring it works perfectly on both X11 and Wayland.

To install the binary, icons, and Start Menu launcher system-wide, simply run:

sudo make -C build install
sudo update-desktop-database /usr/local/share/applications/

Once installed, you can launch TaskManager directly from your Desktop Environment's Application Menu! It will securely prompt for your password via your native graphical prompt (e.g. GNOME PolicyKit dialog) and launch properly.

Running Manually from Terminal

You can still start the task manager normally by running:

/usr/local/bin/taskmanager

Or for full features:

sudo /usr/local/bin/run_taskmanager

🧹 Code Quality and Formatting

The project ships with strict code formatting configurations.

• Run clang-format based on the .clang-format (LLVM Style).
• Static analysis is enabled via the configured .clang-tidy which ensures high code quality while intelligently ignoring UI-framework specific macros.

⌨️ Controls

• Search: Just start typing! The search bar will automatically capture your keystrokes.
• Context Menu: Right-click on any process to reveal options like End Task (Kill) or Open File Location.
• Services: Use the buttons at the bottom of the Services tab to toggle active SystemD units.
