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).

🛠️ Prerequisites

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

• GCC / G++ (supporting C++17)
• GTK+ 3.0 development files
• Make
• dmidecode (Optional, but highly recommended for reading RAM hardware details)
• polkit (Optional, for seamless GUI root access)

Installation on Arch Linux / Manjaro

sudo pacman -S base-devel gtk3 dmidecode polkit

Installation on Ubuntu / Debian

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

🚀 Building the App

Compile using the provided Makefile:

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

To clean the compiled binaries:

make clean

🏃 Running the Application

You can start the task manager normally by running:

./taskmanager

Running with Root Access (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.

Instead of using sudo from the terminal every time, you can integrate it seamlessly into your Desktop Environment using Polkit!

1. Enable the Wrapper: Make the included wrapper script executable:

   chmod +x run_taskmanager.sh

2. Install the Desktop Shortcut: Copy the mytaskmanager.desktop file to your applications folder:

   cp mytaskmanager.desktop ~/.local/share/applications/

   Now you can launch My Linux Task Manager directly from your Application Menu! It will securely prompt for your password via a GUI.

3. (Optional) Bypass Password Prompt: If you want the Task Manager to open instantly without asking for a password every time, you can add a Polkit rule:

   sudo tee /etc/polkit-1/rules.d/99-mytaskmanager.rules <<EOF
   polkit.addRule(function(action, subject) {
       if (action.id == "org.freedesktop.policykit.exec" &&
           action.lookup("program") == "$PWD/run_taskmanager.sh" &&
           subject.user == "$USER") {
           return polkit.Result.YES;
       }
   });
   EOF

⌨️ 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.
