== Notes ==
Also tested with Dell WD19TB Thunderbolt Dock.
== NVIDIA Offload ==
In order to run a program on the NVIDIA gpu, you can use the `nvidia-offload` function, for example:
```
nvidia-offload `nix-shell -p glxinfo --run 'glxgears'`
```
This is a short bash script that sets the proper environment variables and calls your command.
