nsight-compute does nothing upon invocation

Question

I run:

joeuser@myhost$ su
joeuser@myhost# /opt/nvidia/nsight-compute/ncu-ui
joeuser@myhost# 

... and nothing comes up. Why?

(The su is due to permission issues, it's not what this bug is about.)

Answer 1

It is possible (likely?) that another instance of nsight-compute, from a previous invocation of yours, is still running. Try: pgrep ncu or ps aux | grep ncu. If you find a running instance (that's not the grep ncu process mind you) - kill it. But make sure it isn't some other person running it!

Then ncu-ui should start properly.
