Cannot launch any process with any part of NSight Graphics

Developer Tools Nsight Graphics
1

Hi,

I am unable to launch any program from within the NSight Graphics Frame Debugger, or any other tool for that matter. I always get a Launch failure. Even trying something as simple as glxgears doesn’t work. While the application does start and run fine, the Frame Debugger gets a failure.

  • I start the UI interactively “/usr/local/NVIDIA-Nsight-Graphics-2024.2/host/linux-desktop-nomad-x64/ngfx-ui”. The UI seems to work fine.
  • Within the Frame Debugger - Launch option, I specify “/opt/X11/bin/glxgears” and set Automatically Connect to Yes. The glxgears application starts fine and runs but I get the following in the Progress Log:
    “Preparing to launch the Frame Debugger activity on localhost…
    Launch failure: Process creation failure
    Launch failed.”

NOTE: I have had the same results with the following video cards:
GTX 1650 and 430.50 driver
RTX 3050 and 550.120 driver

What other info can I provide that might be helpful?

Thanks,

Hi kr1,

Thank you for using Nsight Graphics and providing your feedback. Linux From Scratch is not officially supported Linux of Nsight Graphics, but could you take some try about these?

  • I notice you run nvidia-smi as root, do you still run ngfx-ui with root?
  • Try launch ngfx-ui as normal user in normal/regular desktop environment (no ssh remote, no x11 forward, etc., just a regular desktop environment with a monitor and a PC host), and launch the glxgear with ngfx-ui, what will happen?

Thanks
An
