Nothing is displayed for Nvidia GPUs

[flyrobot27]

Is there an existing issue for this?

• [X] I searched the existing issues and did not find anything similar.

Current Behavior

When an Nvidia GPU is used, nothing is displayed other than the GPU usage:

Expected Behavior

Memory usage, GPU frequency, etc. should be displayed other than N/A.

Steps To Reproduce

1. Install Resources
2. Install Nvidia Drivers 535. The video card used is a Tesla P100 12GB
3. Open Application and navigate to GPU

Environment

App Version 1.3.0

uname -a output:
Linux cuda-server 6.5.0-26-generic #26~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue Mar 12 10:22:43 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

NVIDIA-SMI 535.161.07  Driver Version: 535.161.07  CUDA Version: 12.2

GPU1: Radeon Pro WX 2100 (Used for display output)
GPU2: Nvidia Tesla P100 12GB

Anything else?

nvtop have no issues accessing the values:

Hi, can you run Resources from the terminal and send me the output?

[flyrobot27]

What is the command for running it?

[flyrobot27]

Nvm I found the command. Here is the debug output:

Could you try running flatpak install org.freedesktop.Platform.GL.nvidia-535-161-07 org.freedesktop.Platform.GL32.nvidia-535-161-07 and then viewing your NVIDIA GPU in Resources again?

[flyrobot27]

Hey, sorry for the late reply. I've tried your command but unfortunately nothing changed.

One difference is that the P100 requires Nvidia's Server driver and needs to have ReBAR enabled. Maybe that's messing something up? I don't know

[nokyan]

The server driver thing might be related to it, reBAR likely not. I don't know too much about NVIDIA's professional GPUs, sorry. I think it might be related to Flatpak, because nvtop works and Resources show the GPU load, which, if NVML fails, will be calculated from individual per-process GPU usage. Per-process GPU usage is gathered by a companion process which is spawned outside Flatpak's sandbox. I'll see if I can find something.

I would like to report that with my NVIDIA card, some things show 0%. Additionally, there are some properties that can be displayed, but others show nothing.

[chris-gputrader]

I get the same as above, NVIDIA GPU is always showing 0%, if I check with nvtop it shows correct utilz %

[nokyan]

Does per-process GPU usage in the Processes view work? Does encoder/decoder utilization work? Can you send me the output of running Resources from the terminal using flatpak run --env=RUST_LOG=resources=debug net.nokyan.Resources?

[chris-gputrader]

flatpak run --env=RUST_LOG=resources=debug net.nokyan.Resources
 DEBUG resources::utils > Running as Flatpak
 INFO  resources::application > Resources (net.nokyan.Resources)
 INFO  resources::application > Version: 1.7.0 ()
 INFO  resources::application > Datadir: /app/share/resources

Per process looks like it reporting GPU% but not in the right for the right gpu maybe? I haven't seen anything in Encoder or Decoder Usage, GPU Memory does seem to be reporting correctly.

[MythicByte]

flatpak run --env=RUST_LOG=resources=debug net.nokyan.Resources

flatpak run --env=RUST_LOG=resources=debug net.nokyan.Resources DEBUG resources::utils > Running as Flatpak INFO resources::application > Resources (net.nokyan.Resources) INFO resources::application > Version: 1.7.0 () INFO resources::application > Datadir: /app/share/resources

[nokyan]

Is this the complete output? It should usually look something like this and go on for quite a while:

[MythicByte]

flatpak run --env=RUST_LOG=resources=debug net.nokyan.Resources

I have the answer for this. If the app is open, this small output appears. However, when the application is launched via the command, then your output appears.
