--- Comment #55 from Aaron Plattner aplattner@nvidia.com --- You shouldn't need libXNVCtrl for this, it's core RandR protocol. But for what it's worth, while the nvidia-settings app as a whole is GPL, the libXNVCtrl library it uses has an MIT license. See the license comment at the top of https://github.com/NVIDIA/nvidia-settings/blob/main/src/libXNVCtrl/NVCtrl.c
