README.md

You may reached here due to lack of /dev/nvidia*:

$ find /dev/nvidia*
/dev/nvidia0
/dev/nvidia-caps
/dev/nvidia-caps/nvidia-cap2
/dev/nvidia-caps/nvidia-cap1
/dev/nvidiactl
/dev/nvidia-modeset
/dev/nvidia-uvm
/dev/nvidia-uvm-tools

Before use this script, ensure you have:

• Secure Boot disabled
• linux-header-$ARCH (e.g. linux-headers-amd64) installed
