LNXLink gpu_nvidia_settings

This module for LNXLink is a drop-in replacement for the bundeled GPU module. It uses nvidia-settings instead of nvidia-smi which might give better results on some (older) Nvidia GPUs.

How to use

You'll only need gpu_nvidia_settings.py. There's no limitations on where you place the file, it might depend on where and how you've installed LNXLink, but it'll work fine even if you place it somewhere in your home directory.

Edit your LNXLink configuration file (see Config file location) and add the following configuration:

custom_modules:
  - <PATH_TO_THE_MODULE>/gpu_nvidia_settings.py

If you manually defined which modules LNXLink should use, make sure to remove gpu from the list. If instead you've loaded all modules by default, add the following lines to your LNKLink configuration:

exclude:
 - gpu

Troubleshooting

Check if nvidia-settings can detect your GPU:

nvidia-settings -q 'gpus'

The output should look something like this:

1 GPU on PWManjaro:0

    [0] PWManjaro:0[gpu:0] (NVIDIA GeForce GTX 770)

      Has the following names:
        GPU-0

Using the gpu id ([gpu:0]) you can query the metrics from nvidia-settings using the following command

nvidia-settings -q '[gpu:0]/GPUUtilization' -q '[gpu:0]/GPUCoreTemp' -q '[gpu:0]/UsedDedicatedGPUMemory' -q '[gpu:0]/TotalDedicatedGPUMemory'

The output should look something like this:

  Attribute 'GPUUtilization' (PWManjaro:0[gpu:0]): graphics=1, memory=1, video=0, PCIe=0

  Attribute 'GPUCoreTemp' (PWManjaro:0[gpu:0]): 38.
    'GPUCoreTemp' is an integer attribute.
    'GPUCoreTemp' is a read-only attribute.
    'GPUCoreTemp' can use the following target types: X Screen, GPU.

  Attribute 'UsedDedicatedGPUMemory' (PWManjaro:0[gpu:0]): 775.
    'UsedDedicatedGPUMemory' is an integer attribute.
    'UsedDedicatedGPUMemory' is a read-only attribute.
    'UsedDedicatedGPUMemory' can use the following target types: GPU.

  Attribute 'TotalDedicatedGPUMemory' (PWManjaro:0[gpu:0]): 1991.
    'TotalDedicatedGPUMemory' is an integer attribute.
    'TotalDedicatedGPUMemory' is a read-only attribute.
    'TotalDedicatedGPUMemory' can use the following target types: GPU.
