 ### The container does not work.
 
-Check that the [NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html) is properly configured in the host. After that, check the environment variable `NVIDIA_DRIVER_CAPABILITIES` after starting a shell interface inside the container.
+Check that the [NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html) is properly configured in the host. Next, check whether your host NVIDIA GPU driver is the `nvidia-headless` variant, which lacks the required display and graphics capabilities for this container.
 
-`NVIDIA_DRIVER_CAPABILITIES` should be set to `all`, or include a comma-separated list of `compute` (requirement for CUDA and OpenCL, or for the [selkies-gstreamer](https://github.com/selkies-project/selkies-gstreamer) WebRTC remote desktop interface), `utility` (requirement for `nvidia-smi` and NVML), `graphics` (requirement for OpenGL and part of the requirement for Vulkan), `video` (required for encoding or decoding videos using NVIDIA GPUs, or for the [selkies-gstreamer](https://github.com/selkies-project/selkies-gstreamer) WebRTC remote desktop interface), `display` (the other requirement for Vulkan), and optionally `compat32` if you use Wine or 32-bit graphics applications.

 Moreover, if you are using custom configurations, check if your shared memory path `/dev/shm` has sufficient capacity, where expanding the capacity is done by adding `--tmpfs /dev/shm:rw` to your Docker command or adding the below lines to your Kubernetes configuration file.
