nvidia-modprobe(1) Load the NVIDIA kernel module and create NVIDIA character device files.


nvidia-modprobe [options]
nvidia-modprobe [options] --create-nvidia-device-file=MINOR-NUMBER
nvidia-modprobe [options] --module-instance=MODULE-INSTANCE


The nvidia-modprobe utility is used by user-space NVIDIA driver components to make sure the NVIDIA kernel module is loaded and that the NVIDIA character device files are present. These facilities are normally provided by Linux distribution configuration systems such as udev. When possible, it is recommended to use your Linux distribution's native mechanisms for managing kernel module loading and device file creation. This utility is provided as a fallback to work out-of-the-box in a distribution-independent way.

When installed by nvidia-installer , nvidia-modprobe is installed setuid root.

Users should not normally need to run nvidia-modprobe by hand: the NVIDIA user-space driver components will fork(2)/exec(3) it when needed.

When run without any options, nvidia-modprobe will load the NVIDIA kernel module and then exit. When the --module-instance option is specified on systems with multiple NVIDIA kernel modules, nvidia-modprobe will load the corresponding NVIDIA kernel module and then exit. When the --create-nvidia-device-file option is specified, nvidia-modprobe will also create the requested device file.

-v, --version
Print the utility version and exit.
-h, --help
Print usage information for the command line options and exit.
-c MINOR-NUMBER, --create-nvidia-device-file=MINOR-NUMBER
Create the NVIDIA device file with the given minor number; this option can be specified multiple times to create multiple NVIDIA device files.
Load the required NVIDIA kernel module that corresponds to the specified MODULE-INSTANCE value. The value should be between 0 and 7.


-u, --unified-memory
Load the NVIDIA Unified Memory kernel module or create device files for it, instead of the NVIDIA kernel module.
-m, --modeset
Load the NVIDIA modeset kernel module and create its device file.


Run `/sbin/modprobe nvidia`
nvidia-modprobe -c 0 -c 1
Run `/sbin/modprobe nvidia` and create /dev/nvidia0 and /dev/nvidia1
nvidia-modprobe -i 0
Run `/sbin/modprobe nvidia0`
