Linux Nvidia Driver Error — GPU Not Working Fix

What Does This Error Mean?

Nvidia graphics cards on Linux often need proprietary drivers that are not installed by default. Without the correct driver, Linux uses a generic VESA or Nouveau driver that offers poor performance and may not support your monitor resolution. Common errors include a black screen after boot, extremely low resolution, or errors like 'Failed to initialize NVML' in applications.

Affected Models

Ubuntu
Debian
Fedora
Linux Mint
Pop!_OS
Arch Linux

Common Causes

The proprietary Nvidia driver is not installed — only the open-source Nouveau driver is loaded
A kernel update changed the kernel version and the Nvidia driver module needs to be rebuilt
A conflict between the Nouveau driver and the Nvidia driver is causing both to fail
The Nvidia driver was installed but Secure Boot is blocking it because it is unsigned
The wrong version of the Nvidia driver was installed for your GPU model

How to Fix It

Install the recommended Nvidia driver (Ubuntu). Open a terminal and run: ubuntu-drivers devices to see the recommended driver. Then: sudo ubuntu-drivers install to install it automatically.

This is the easiest method on Ubuntu and Linux Mint. The ubuntu-drivers tool finds the right driver version for your specific GPU.
Install Nvidia driver manually from the terminal. Run: sudo apt install nvidia-driver-[version] (replace [version] with the number, e.g., 535). Reboot when finished.

Check nvidia.com for the latest driver version for your GPU. On Fedora: sudo dnf install akmod-nvidia. On Arch: sudo pacman -S nvidia
Disable Nouveau before installing Nvidia. Create a blacklist file: sudo nano /etc/modprobe.d/blacklist-nouveau.conf and add: blacklist nouveau and: options nouveau modeset=0. Then: sudo update-initramfs -u and reboot.

Nouveau (the open-source Nvidia driver) and the proprietary Nvidia driver cannot run at the same time. Blacklisting Nouveau ensures it does not load.
Disable Secure Boot if the driver is blocked. In your UEFI/BIOS settings (usually accessed by pressing F2 or Del at startup), find Secure Boot and disable it. Then reinstall the Nvidia driver.

Secure Boot requires all kernel modules to be signed. Unsigned Nvidia drivers will be blocked. Disabling Secure Boot allows them to load.
Verify the driver is loaded. After rebooting, run: nvidia-smi to confirm the Nvidia driver is loaded and shows your GPU information.

If nvidia-smi works, the driver is installed and running correctly. If it fails, the driver did not load — check journalctl for error messages.

When to Call a Professional

Nvidia driver issues are among the most common Linux problems but they are fixable. If you are comfortable with a terminal, the steps below work on most systems. For complex Secure Boot situations, a Linux-knowledgeable technician can help set up driver signing.

Frequently Asked Questions

Should I use the Nvidia driver from the official Nvidia website or from my distribution's repository?

Use your distribution's repository version whenever possible. Repository drivers are tested against your specific kernel version and update automatically. The official Nvidia installer requires you to reinstall manually after every kernel update, which is easy to forget and causes breakage.

After a kernel update, my Nvidia driver stopped working. Why?

The Nvidia proprietary driver is a kernel module — a piece of code that plugs into the Linux kernel. When the kernel version changes, the module must be rebuilt to match. On Ubuntu with DKMS (Dynamic Kernel Module Support), this happens automatically. If it did not happen, reinstall the driver package.

What is the difference between Nvidia and Nouveau?

Nouveau is an open-source reverse-engineered Nvidia driver maintained by the Linux community. It works for basic display output but offers poor performance and limited feature support. The proprietary Nvidia driver is made by Nvidia and offers full performance, CUDA support, and better compatibility — but requires more effort to install on Linux.
