Tried multiple versions of Nsight even the latest one. I can capture (with F11, or ctrl+Z on older Nsight). So I can see the HUD/overlay and I can use hotkeys to move between frames. But I can’t attach Nsight UI to the selected process, it’s just grayed out (disabled) in list of processes.
I had some success in a past on older ubuntu+nsight, but I don’t remember which version was ok. So I don’t know since when the nsight got broken.
Ubuntu 20.10
NVidia driver 460.32.03
GeForce GTX 1050 (on laptop)
