Debian NVIDIA driver install for headless server

deb-nvidia-headless.txt

The current nvidia-driver package in Debian 12 is designed for desktop systems and has dependencies to install Xorg
and other desktop packages. There is no package similar to the nvidia-headless package provided by Ubuntu. These were
the minimal packages (and their dependencies) I had to install to get a Quadro P400 running on a headless Debian 12
box for transcoding use.

install dkms nvidia-kernel-dkms libnvcuvid1 libnvidia-encode1 nvidia-smi linux-headers-amd64 nvidia-driver-bin

rmmod nouveau
modprobe nvidia

Check the output of nvidia-smi and the card should be properly detected and ready for use.
