Hi,

I've recently acquired a new GPU and fail to get it to work with
darktable. Here are some infos:

System: Debian stable 5.10.0-21-amd64
GPU: NVIDIA GeForce GTX 1650

I installed the driver using

   apt install nvidia-driver

as suggested by nvidia-detect.

The modules are loaded:

   lsmod | grep nvidia
   nvidia_drm             73728  4
   drm_kms_helper        278528  1 nvidia_drm
   nvidia_modeset       1204224  8 nvidia_drm
   nvidia              35528704  367 nvidia_modeset
   drm                   626688  8 drm_kms_helper,nvidia,nvidia_drm

But darktable doesn't use the GPU:
