No devices were found even after nvidia driver install

Hi everybody,
I have a ThinkPad with a Quadro T500 Mobile Graphics Card, running Arch Linux.
After installing nvidia (535) and setting everything up according to the Arch Wiki, nvidia-smi tells me, that “No devices were found”.
However, lspci | grep 3D yields:
01:00.0 3D controller: NVIDIA Corporation TU117GLM [Quadro T500 Mobile] (rev a1)

lsmod | grep nvidia yields:
nvidia_uvm 3477504 0
nvidia 62713856 1 nvidia_uvm
Nouveau is not loaded, so I’m kind of out of ideas here …
