GeForce GTX 1650 Ti and Linux Mint 19.3

If there’s no xorg.conf, you don’t need to delete it.

The post describes two different setups, PRIME output with support for external monitors and PRIME offload aka render offload without it.

Not the “user” directory which is in /home on linux but /usr which is short for “unix special resources”, it’s a system directory. To modify the files, e.g. open a terminal and run
sudo -i
to get a root shell, then
nano -w /usr/share/X11/xorg.conf.d/10-amdgpu.conf
modify, press ctrl+o ctrl+x to save and exit the first file
nano -w /usr/share/X11/xorg.conf.d/10-nvidia.conf
ctrl+o ctrl+x to save and exit the second file
