 === Current Nvidia drivers ===
-Batocera includes most available Linux versions of the Nvidia drivers available at the time of release provided they're compatible with the shipped Linux Kernel.
+Batocera includes the Linux versions of the Nvidia drivers and will use them automatically. Details about which driver is being used after boot can be found in the log file at ''/userdata/system/logs/nvidia.log''.
-During boot, Batocera will detect the "appropriate" driver for your Nvidia GPU automatically and use it accordingly.
-If your Nvidia card is not detected properly at boot, please refer to the log file at ''/userdata/system/logs/nvidia.log'' for further details.
+The automatic setting can be overridden by [[:edit_boot_partition#plugging_it_into_another_machine|modifying the boot configuration file]]. At the top level, find the ''batocera-boot.conf'' file and uncomment (i.e. remove the initial #) the ''nvidia-driver=true'' line. If the line is not present, add it anywhere. ''true'' can be replaced to specify a specific version.
-We do not recommend you override the automatic setting, however options are available if you need to troubleshoot. [[:edit_boot_partition#plugging_it_into_another_machine|plug your SD-card/USB drive into a computer]].
-At the top level, find the ''batocera-boot.conf'' file and uncomment (i.e. remove the initial #) the ''nvidia-driver=true'' line. If the line is not present, add it anywhere.
-In the latest config file, it should look like this:

-How can you tell if the Nvidia driver is correctly set up? Go to **SYSTEM SETTINGS** -> **INFORMATION** and see if the OpenGL version mentions **NVIDIA** in its version. If it does, you're all set. If it mentions **MESA**, that means that the Nvidia driver is not correctly activated.

+If the second GPU has outputs that are not accessible by the primary GPU, you can use [[https://wiki.archlinux.org/title/PRIME#Reverse_PRIME|Reverse PRIME]] to make use of them. This will involve using the primary GPU to render the images, and then pass them off to the second GPU.

-===== Intel i965 =====
-Although most Intel integrated graphics should work out of the box, some chips such as the one in the [[https://www.intel.com.au/content/www/au/en/products/sku/89190/intel-nuc-kit-nuc6i5syh/specifications.html|NUC6i5SYH]] Intel NUC Kit require activating the latest official i965 drivers.
-To activate these drivers, [[:edit_boot_partition#plugging_it_into_another_machine|plug your SD-card/USB drive into a computer]]. At the top level, find the ''batocera-boot.conf'' file and uncomment (i.e. remove the initial #) the ''intel-i965-driver=true'' line. If the line is not present, add it. It should look like this:
