====== Ubuntu - GPU - Nouveau - Blacklist the Nouveau driver ======

To prevent the host OS from loading the built-in nouveau driver for NVIDIA GPUs.

----

===== Check if the Nouveau driver is loaded =====

<code bash>
lsmod | grep nouveau
</code>

returns:

<code>
nouveau              1949696  0
mxm_wmi                16384  1 nouveau

</code>

===== Blacklist the nouveau driver =====

<code bash>
sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nouveau.conf"
sudo bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nouveau.conf"
</code>


<WRAP info>
**NOTE:**  The **/etc/modprobe.d/blacklist-nouveau.conf** could also be created manually, if required.

  * The **blacklist nouveau** line suggests that the module loading system should not load the Nouveau driver automatically.
  * The **options nouveau modeset=0** line aims to prevent Nouveau from initializing display modes early in the boot process.

</WRAP>

----

===== Confirm the content of the newly created modeprobe file blacklist-nouveau.conf =====

<code bash>
cat /etc/modprobe.d/blacklist-nouveau.conf
</code>

returns:

<code>
blacklist nouveau
options nouveau modeset=0
</code>

----

===== Udate kernel initramfs =====

<code bash>
sudo update-initramfs -u
</code>

----

===== Reboot the system =====

<WRAP important>
**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 of an alternative GPU driver.

</WRAP>


<code bash>
sudo reboot
</code>
