Many people think installing Nvidia drivers on Linux is hard. But it is simple if you follow the steps. This guide will help you do it easily.

Why Install Nvidia Drivers?

Basic drivers in Debian 13 work for daily tasks but do not use your Nvidia card fully. Official Nvidia drivers give you:

• Better gaming performance.
• Faster video editing.
• Support for multiple monitors.
• Hardware video acceleration.
• Better 3D graphics.

What You Need

• Computer with Nvidia graphics card.
• Debian 13 installed.
• Sudo access.
• Internet connection.

Step 1: Update Your System

Open terminal and type:

sudo apt update
sudo apt full-upgrade

Restart computer:

sudo reboot

Step 2: Check Your Card

Type this to see your card:

lspci | grep -i nvidia

Write down the model name.

Step 3: Add Repositories

Open sources file:

sudo nano /etc/apt/sources.list

Add contrib, non-free, and non-free-firmware to lines:

deb http://deb.debian.org/debian/ trixie main contrib non-free non-free-firmware
deb-src http://deb.debian.org/debian/ trixie main contrib non-free non-free-firmware

For security updates add:

deb http://deb.debian.org/debian-security trixie-security main contrib non-free non-free-firmware

Save with Ctrl + O and exit with Ctrl + X.

Step 4: Update Lists

sudo apt update

Step 5: Find Right Driver

Install detection tool:

sudo apt install nvidia-detect

Run it:

nvidia-detect

This tells you which driver to install.

Step 6: Install Driver

For most cards:

sudo apt install nvidia-driver

For old cards:

sudo apt install nvidia-legacy-390xx-driver

If you have black screen problems, blacklist Nouveau:

sudo bash -c "echo 'blacklist nouveau' > /etc/modprobe.d/blacklist-nouveau.conf"
sudo update-initramfs -u

Step 7: Restart

sudo reboot

Step 8: Check Installation

Type this:

nvidia-smi

You should see GPU info, driver version, and usage. If yes, the driver is working.

Common Problems

Boot recovery mode, remove driver:

sudo apt remove nvidia-driver

Restart and try again.
