  2. run host/linux-desktop-nomad-x64/nv-nsight-gfx
  3. quick launch with inputs

Thank you for the very detailed report!

We will try to reproduce the issue on our side and let you know.


–Internal Reference–

After I installed

(NOT apt-get install nvidia-418),

the problem was fixed even the official driver is shown as open source also

I observed a new problem with official nvidia driver

quick launch -> attach -> the process name list box is empty even I do have my opengl app running.

(to launch my opengl app has no problem. Thus, the app is fine)


We are currently renaming the “attach” tab because of this very confusion.

Attach in Nsight Graphics means “Attach to an injected process”. If you look in the launch tab, you will notice an option that says “Automatically connect”. If set to “no”, then said processes will appear in the “attach” tab. This is helpful when injecting a game running through steam, or any other kind of launcher.


Sorry again for the confusion.
