NVIDIA drivers don't load after a reboot (LXC)

NVIDIA persistanced

Source: https://gist.github.com/ngoc-minh-do/fcf0a01564ece8be3990d774386b5d0c#enable-persistence-mode

Enable persistence mode Nvidia device nodes (/dev/nvidia*) are not loaded at boot. Additionally, when they are no longer in use, the NVIDIA kernel driver deactivates the device state.

Enabling Nvidia persistence mode keeps the NVIDIA character device files open, preventing the kernel driver from deactivating the device state when no other process is using the device.
