====== Ubuntu - GPU - NVIDIA GPU - Setup - Setup manually ======

<WRAP important>
**WARNING:**  Manual installation of NVIDIA drivers on Ubuntu, particularly from the official NVIDIA.com source, is not recommended for all users due to potential compatibility issues with future kernel updates.

  * This approach requires manual recompilation or re-installation of the driver each time the kernel is updated, as the NVIDIA kernel module may not automatically adapt to the new kernel version.
  * Such updates can lead to system instability, the inability to boot into the graphical interface, or the driver ceasing to function entirely.
  * Opting for drivers provided through the Ubuntu repositories or via a PPA is generally safer, ensuring smoother updates and system stability.

===== Identify the NVIDIA GPU Model =====

<code bash>
sudo lshw -numeric -C display

or

sudo lspci -vnn | grep VGA

or

sudo ubuntu-drivers devices
</code>

<WRAP info>
**NOTE:**  This will help to determine which driver is needed.

===== Download the driver setup script =====

Visit the [[https://www.nvidia.com/en-in/drivers/unix/|Official Nvidia website]].

Download the appropriate driver for your graphics card.

<code bash>
sudo wget https://us.download.nvidia.com/XFree86/Linux-x86_64/510.60.02/NVIDIA-Linux-x86_64-510.60.02.run
</code>

===== install the prerequisites which will be required by the driver for successful installation =====

<code bash>
sudo apt install build-essential libglvnd-dev pkg-config
</code>

----

===== Disable Nouveau Nvidia Driver =====

The default Nouveau Nvidia driver must be disabled before installing the official Nvidia driver.

  * This step is crucial for preventing conflicts between drivers.

See [[Ubuntu:GPU:Nouveau:Blacklist the Nouveau driver|Blacklist the Nouveau driver]].

**WARNING:**  After the reboot you may end up without GUI at all.

  * Be sure that you have the SSH enabled on your system to be able login remotely or use **CTRL+ALT+F2** to switch TTY console and continue with the installation.
