Which NVIDIA driver should be installed for NX? The graphics card model is displayed as NVIDIA Corporation Device 1ad1, and the graphics card is checked as Tegra PCIe x4/x8 Endpoint/Root Complex.
The Jetson’s GPU is an integrated GPU (iGPU) directly wired to the memory controller. This requires a special driver. The drivers you see “out in the wild” are for discrete GPUs (dGPU) on the PCI bus. When you flash with JetPack/SDK Manager it puts the correct driver on it. There is no need for an outside driver.
Typically the iGPU driver will have conflicts with any dGPU driver (it looks like the IGX Orin can have a dGPU as well, but this is not the traditional Jetson), so adding another driver risks needing to flash again (technically you could revert a dGPU install, but that isn’t usually as easy as it sounds).

Sorry for being late. Thank you very much for your reply. Is there a tutorial on how to use this driver? I’m really sorry to take up your time.
Already explained in your duplicated topic…
There is no driver for your usecase.

Incidentally, for a GPU to be available on the PCI bus, the device itself must be on PCI. Since this is an iGPU there is no PCI access.
