3. To install the dGPU drivers, use the install command with the dGPU parameter (note that sudo
must be used to install drivers):
$ sudo nvgpuswitch.py install dGPU
The install command prints out the list of commands that will be executed as part of the
driver install and then continues to execute those commands. This aids with debugging if any of
the commands fail to execute.
The following arguments may also be provided with the install command:
$ nvgpuswitch.py install -h
usage: nvgpuswitch.py install [-h] [-f] [-d] [-i] [-v] [-l LOG] [-r
[L4T_REPO]] {iGPU,dGPU}
positional arguments:
{iGPU,dGPU}
optional arguments:
-h, --help
-f, --force
-d, --dry

4. The dGPU driver install may be verified using the query command:
$ nvgpuswitch.py query
dGPU (cuda-drivers, 510.73.08-1)
Quadro RTX 6000, 24576 MiB
5. After the dGPU drivers have been installed, rebooting the system will complete the switch to the
dGPU. At this point the Ubuntu desktop will be output via DisplayPort on the dGPU, so the display
cable must be switched from the onboard HDMI (port 10) to DisplayPort (port 4) on the dGPU.
Note: If the output connection isn't switched before the Clara AGX Developer Kit finishes
rebooting, the terminal screen will hang during booting.
6. Modify the PATH and LD_LIBRARY_PATH . CUDA installs its runtime binaries such as nvcc into
its own versioned path, which is not included by the default $PATH environment variable.
Because of this, attempts to run commands like nvcc will fail on dGPU unless the CUDA 11.6
path is added to the $PATH variable. To add the CUDA 11.6 path for the current user, add the
following lines to $HOME/.bashrc after the switch to dGPU:
export PATH=/usr/local/cuda-11.6/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-11.6/lib64:$LD_LIBRARY_PATH
