This guide is tailored to help you get your NVIDIA GPU working as the primary graphics processor on your Bazzite-Nvidia system.

Understanding the Problem

The core issue here is that, despite having an NVIDIA GPU and installing the NVIDIA-optimized version of Bazzite, the system defaults to using the Intel integrated graphics. This can lead to significant performance drops, making games run poorly and applications feel sluggish. To truly grasp this problem, it's crucial to understand the intricacies of how your system is utilizing its graphics processing units. Let's delve into some key aspects that shed light on why this might be happening and what you can do to rectify it. First off, the system's initial configuration post-installation plays a significant role. Sometimes, the default settings might not automatically recognize and prioritize the NVIDIA GPU. This is where manual intervention becomes necessary. Secondly, the drivers themselves are a critical component. Ensuring that you have the correct NVIDIA drivers installed and that they are functioning optimally is paramount. This involves not only installing the drivers but also verifying their proper operation. Thirdly, the interplay between the NVIDIA drivers and the Intel integrated graphics drivers can sometimes lead to conflicts. This is where techniques like blacklisting the i915 driver or adjusting kernel parameters come into play. Finally, understanding how applications are being launched and which GPU they are utilizing is essential. This is where tools like glxinfo and environment variables come into the picture. By dissecting these various facets, you can gain a comprehensive understanding of the problem and be better equipped to troubleshoot and resolve it. Let’s get your NVIDIA GPU doing the heavy lifting it was built for!

Diagnosing the Issue

Before we jump into solutions, let's make sure we've properly diagnosed the problem. It's like a doctor figuring out what's wrong before prescribing medicine. Here’s how you can check what's going on under the hood:

Check OpenGL Renderer: Open your terminal and type glxinfo | grep "OpenGL renderer". This command tells you which GPU is being used for OpenGL rendering. If it says Mesa Intel(R) HD Graphics... instead of NVIDIA, that's a clear sign your iGPU is in charge.
Verify NVIDIA Drivers: Run nvidia-smi. This command shows you the status of your NVIDIA GPU and drivers. If it runs and displays information about your GPU, your drivers are likely installed correctly. If you get an error, there might be a driver issue.
List Loaded Modules: Use lsmod | grep nvidia to check if the NVIDIA modules are loaded in the kernel. This confirms that the NVIDIA drivers are not only installed but also actively running.
Observe Game Performance: Launch a game and see how it performs. Extremely slow loading times, stuttering, or crashes can indicate that the game is not using the NVIDIA GPU.

By using these diagnostic steps, you'll get a much clearer picture of whether your NVIDIA GPU is the one in use or whether your system is defaulting to the Intel integrated graphics. This information is crucial for directing your troubleshooting efforts and ensuring that you're applying the right fixes. Remember, accurate diagnosis is half the battle! We want to make sure that your system is running at its best, utilizing the full potential of your NVIDIA GPU. So, take a moment to run these checks, and let's get to the bottom of this together!

Troubleshooting Steps: Let's Fix This!

Alright, now for the fun part – fixing the issue! We're going to walk through several steps, starting with the simplest and moving towards more advanced solutions. Think of it as a process of elimination; we'll try different things until we hit the sweet spot.

Supergfxctl to the Rescue:
- supergfxctl is a handy tool for managing GPUs on hybrid systems. Let's start by setting the GPU mode to Hybrid: sudo supergfxctl -m hybrid. This tells the system to use the NVIDIA GPU for demanding tasks and the Intel iGPU for power saving.
- Then, switch to NVIDIA mode: sudo supergfxctl -m nvidia. This forces the system to use the NVIDIA GPU for everything. Reboot after each command to see if it makes a difference.
Environment Variables: Tell the System What to Do:
- Environment variables can be used to instruct applications which GPU to use. Try setting these before launching a game or application:
  - __NV_PRIME_RENDER_OFFLOAD=1
  - __GLX_VENDOR_LIBRARY_NAME=nvidia
- You can set these in the terminal before launching an application, like this:
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia ./your_game ```
- For a more permanent solution, you can add these variables to your ~/.bashrc or ~/.profile file.
Blacklisting the i915 Driver (Use with Caution!):
- This is a more aggressive approach. Blacklisting the i915 driver (Intel's iGPU driver) prevents it from loading, forcing the system to use the NVIDIA GPU.
- Warning: This can cause issues if not done correctly, so proceed carefully.
- Create or edit /etc/modprobe.d/blacklist.conf and add the line blacklist i915.
- Regenerate the initramfs: sudo dracut -f.
- Reboot your system.
- If you encounter issues, you can remove the line from the blacklist file and regenerate initramfs again.
Kernel Parameter: Force NVIDIA:
- Edit your GRUB configuration file (usually /etc/default/grub) and add nvidia-drm.modeset=1 to the GRUB_CMDLINE_LINUX_DEFAULT line.
- Update GRUB: sudo grub2-mkconfig -o /boot/grub2/grub.cfg (or the appropriate command for your system).
- Reboot your system.
Disable Wayland (If Applicable):
- Wayland, the display server protocol, can sometimes have issues with NVIDIA drivers. If you're using Wayland, try switching to X11.
- You can usually select X11 at the login screen.

Remember, troubleshooting is often a process of trial and error. Take your time, follow the steps carefully, and reboot your system after each significant change to see if it has made a difference. We're in this together, and we'll get your NVIDIA GPU running smoothly! Let’s make your Bazzite-Nvidia experience awesome!

Advanced Troubleshooting (If the Basics Don't Cut It)

Okay, so you've tried the basic troubleshooting steps, and your NVIDIA GPU is still playing hide-and-seek? Don't worry, we've got some more advanced techniques up our sleeves. Sometimes, the issue is a bit more complex and requires a deeper dive into the system's configuration.

Verify Driver Installation and Version:
- Double-check that your NVIDIA drivers are correctly installed and that you're using the recommended version for your GPU and Bazzite-Nvidia. You can do this by running nvidia-smi. The output will show you the driver version.
- Sometimes, a driver update or a downgrade can resolve compatibility issues. Check the NVIDIA website or your distribution's package manager for available drivers.
Check for Conflicting Packages:
- In some cases, conflicting packages can interfere with the NVIDIA drivers. Look for any packages related to Intel graphics that might be causing issues.
- You can use your distribution's package manager (e.g., dnf for Fedora-based systems) to list installed packages and remove any potential conflicts.
Inspect Xorg Configuration:
- The Xorg configuration file (/etc/X11/xorg.conf or files in /etc/X11/xorg.conf.d/) can sometimes be the culprit. Incorrect settings can prevent the NVIDIA GPU from being used.
- Check these files for any manual configurations that might be overriding the default GPU selection. You might need to create or modify these files to explicitly tell Xorg to use the NVIDIA GPU.
- A basic Xorg configuration for NVIDIA might look like this:
```
Section "Device"
    Identifier     "Nvidia Device"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GTX 1050"  # Replace with your GPU model
EndSection

    DefaultDepth   24
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection
```
DRI Prime:
- DRI (Direct Rendering Infrastructure) Prime is a technology that allows you to offload rendering to a different GPU. You can use it to explicitly tell applications to use the NVIDIA GPU.
- Try running applications with the DRI_PRIME=1 environment variable:
```
DRI_PRIME=1 ./your_application
```
Check System Logs:
- System logs can provide valuable clues about what's going wrong. Check logs like /var/log/Xorg.0.log and /var/log/syslog for any error messages related to NVIDIA drivers or GPU initialization.
