Dual GPUs on Linux: 

Using dual GPUs on Linux involves setting up two graphics cards to work together in one computer. This can improve performance for gaming and other graphics-heavy tasks. 

It requires careful installation of drivers for each GPU and proper configuration of your system settings. Linux supports dual GPUs, but it can be more complex to set up compared to Windows. You might need to adjust settings and troubleshoot issues to get both GPUs working effectively.

How To Set Up Dual GPUs On Linux?

Setting up dual GPUs on Linux involves several steps to ensure both graphics cards work together effectively. Here’s a simple guide to help you through the process:

1. Check Hardware Compatibility:

Make sure your motherboard has enough PCIe slots for both GPUs. Check if your power supply can handle the extra power needed and that your case has enough space for both cards.

2. Install the GPUs:

Physically install both GPUs into the PCIe slots on your motherboard. Connect the necessary power cables to each GPU and ensure they are securely seated.

3. Install Drivers:

• NVIDIA GPUs Install the NVIDIA motorists from their website or your Linux distribution’s depository. Use the command line or graphical tools to insure the motorists are rightly installed.
• AMD GPUs: Use the open-source Mesa drivers or AMD’s proprietary drivers, depending on your preference. Install them through your package manager or directly from AMD’s website.

4. Configure the Display Server:

• Xorg: Edit the `xorg.conf` file to configure how both GPUs are used. You may need to specify settings for each GPU and how they should handle displays. This file is usually located in `/etc/X11/`.
• Wayland: This display server is newer and might not support dual GPUs as well as Xorg. For best results, use Xorg if possible.

5. Adjust System Settings:

Use system tools and commands to verify that both GPUs are recognized and working. Commands like `lspci` can list your hardware, and tools like `nvidia-settings` or `radeon-profile` can help manage GPU settings.

6. Test and Optimize:

Run some games or applications to see if both GPUs are being used effectively. You might need to tweak settings or troubleshoot any issues that arise. Monitor temperatures and performance to ensure everything is working correctly.

How Do I Check If Both GPUs Are Working On Linux?

To ensure both GPUs are functioning properly on your Linux system, follow these steps:

1. Use the `lspci` Command:

The `lspci` command lists all PCI devices connected to your system, including GPUs. Open a terminal and type:

lspci | grep -i vga

This command will show information about your GPUs. You should see entries for both graphics cards.

2. Check Driver Installation:

Verify that the correct drivers are installed and loaded for both GPUs. For NVIDIA GPUs, use:

nvidia-smi

For AMD GPUs, you can use:

glxinfo | grep "OpenGL renderer"

These commands should display information about the GPUs and confirm that the drivers are active.

3. Use `nvidia-settings` for NVIDIA GPUs:

If you have NVIDIA GPUs, you can use the `nvidia-settings` tool to check GPU status and settings. Open a terminal and type:

nvidia-settings

This tool provides a graphical interface to view information about your NVIDIA GPUs, including temperature, usage, and more.

4. Check GPU Usage with `watch` Command:

To see how each GPU is being used, you can use the `watch` command to monitor GPU usage in real-time. For NVIDIA GPUs:

watch -n 1 nvidia-smi

For AMD GPUs, use:

watch -n 1 radeontop

These commands will update the display every second, showing real-time usage statistics.

5. Review Logs and System Messages:

Check system logs for any errors related to GPU detection or driver issues. Look in files like `/var/log/Xorg.0.log` or use the `dmesg` command to see kernel messages:

dmesg | grep -i gpu

This helps identify if there are any problems with GPU initialization or conflicts.

How Can I Troubleshoot Issues With Dual GPUs On Linux?

To troubleshoot issues with dual GPUs on Linux, start by checking if both GPUs are recognized using the lspci command. Make sure the correct drivers are installed for each GPU—NVIDIA drivers for NVIDIA cards and Mesa or AMD drivers for AMD cards. 

Use tools like nvidia-settings or radeon-profile to manage and verify GPU settings. If you encounter conflicts or errors, review system logs in /var/log/ or use the dmesg command to check for messages related to GPUs. 

For further help, consult Linux forums or the support pages for your GPU’s manufacturer, such as NVIDIA’s Linux support page or AMD’s support page.

How Do I Know If My Linux Distribution Supports Dual GPUs? 

To find out if your Linux distribution supports dual GPUs, check the distribution’s documentation or support forums. Most popular distributions like Ubuntu, Fedora, and Arch Linux offer support for dual GPUs, but you might need to configure settings manually.
