LinMan - Linux Device Manager

A native, standalone device manager for Linux systems that provides a Windows Device Manager-like interface for hardware diagnostics and management.

Features

• Privilege Levels: Starts as User, switch to Root via toolbar for advanced features
• Stability: Uses handshake logic to ensure smooth User -> Root transition
• Monitors: Native EDID parsing for real monitor model names
• RAM: DMI decoding (Root only)
• Interface: Windows Device Manager look and feel
• Real-time Monitoring: Automatic device detection using udev
• Device Properties: View detailed information about each device
• Driver Management: Unbind drivers, rescan hardware, unload modules (Root only)

Screenshots

Main Window - User Mode

The main interface showing all detected hardware organized by category. Devices are displayed in a tree structure similar to Windows Device Manager.

Root Mode

Switch to Root Mode for advanced features like driver management, unbinding drivers, rescanning hardware, and viewing detailed RAM stick information using dmidecode.

Device Properties Dialog

Double-click any device to view detailed properties including device type, manufacturer, driver information, and device status. Shows three tabs: General, Driver, and Details.

Requirements

• Linux operating system
• Python 3.8 or higher
• X11 display server (for GUI)
• System utilities: lspci, dmidecode (for RAM details)

Installation

Method 1: Using Virtual Environment (Recommended)

1. Clone or download the repository:

   cd /path/to/LinMan-Linux-Device-Manager-main

2. Create a virtual environment:

   python3 -m venv venv

3. Activate the virtual environment:

   source venv/bin/activate

4. Install dependencies:

   pip install -r requirements.txt

5. Run the application:

   python win_device_manager.py

Method 2: System-wide Installation

1. Install system dependencies (Debian/Ubuntu):

   sudo apt update
   sudo apt install python3-pip python3-pyside6 python3-pyudev lspci dmidecode

   For Fedora/RHEL:

   sudo dnf install python3-pip python3-pyside6 python3-pyudev pciutils dmidecode

   For Arch Linux:

   sudo pacman -S python-pip python-pyside6 python-pyudev pciutils dmidecode

2. Install Python dependencies:

   pip install --user PySide6 pyudev

3. Run the application:

   python3 win_device_manager.py

Method 3: Using pipx (For isolated installation)

1. Install pipx if not already installed:

   python3 -m pip install --user pipx
   python3 -m pipx ensurepath

2. Install dependencies:

   pipx install PySide6
   pipx inject PySide6 pyudev

3. Run the application:

   python3 win_device_manager.py

Usage

Basic Usage

• Launch the application:

  python3 win_device_manager.py

• View devices: Devices are organized by category in a tree structure

• Device Properties: Double-click any device to view detailed properties

• Scan for changes: Click the "Scan" button in the toolbar to refresh the device list

Root Mode

For advanced features like driver management and RAM details:

1. Click the "Root Mode" button (shield icon) in the toolbar
2. Enter your password when prompted
3. The application will restart with root privileges

Root mode features:

• View detailed RAM stick information (using dmidecode)
• Unbind device drivers
• Rescan/reprobe hardware
• Unload kernel modules

Dependencies

The application requires the following Python packages:

• PySide6 >= 6.0.0 - Qt6 bindings for Python
• pyudev >= 0.24.0 - Linux device management

These are automatically installed when using requirements.txt.

Troubleshooting

"Display connection failed" error

Make sure you have an X11 display server running:

echo $DISPLAY

If empty, set your display:

export DISPLAY=:0

Permission denied errors

Some device information requires root access. Use the Root Mode button in the toolbar.

"No module named 'PySide6'" error

Make sure you've installed the dependencies:

pip install -r requirements.txt

Virtual environment not activating

Make sure you have python3-venv installed:

sudo apt install python3-venv  # Debian/Ubuntu
sudo dnf install python3-venv  # Fedora/RHEL

System Requirements

• Operating System: Linux (kernel 3.0+)
• Python: 3.8 or higher
• RAM: 512 MB minimum
• Disk Space: ~300 MB for dependencies
• Display: X11 with resolution 1024x768 or higher

Notes

• The application requires a running X11 session
• Some features may vary depending on your Linux distribution
• Virtual/system devices are hidden by default (can be shown via Root Mode)
• The handshake file is stored in /tmp/linman_root_active.lock
