If you decide to install the proprietary drivers, you will have to enable the "contrib" and "non-free" repositories; for this, if you are using the free repos "main", I opened the console and logged in as "root" run the script to enable them by typing "nonfree".
Enabled these repositories
1) In the console as "root" execute:
apt install nvidia-detect
2) Once installed, in the same terminal run the program >> nvidia-detect
3) Go to: Start> Administration> Auxtral Settings, in the "Device Drivers" tab, check the NVIDIA drivers box and click "Save Drivers". This will download and install the proprietary NVIDIA drivers from the Debian repositories.
NOTE: in case this method has not worked for you, from the console as root execute:
/usr/lib/solydxk/ddm-nvidia.sh
when i finish do:
apt install nvidia-xconfig and when it finishes installing run it >> nvidia-xconfig
