Hi! Here is the what is shows when I run top:

It seems that 5 rg process takes a lot of CPU, and I have no idea what they are. Here is the jtop panel:

It also shows a large CPU usage, but I do not know where they come from. Here is the dmesg:

[15962.651404] pwm-tegra-tachometer 39c0000.tachometer: Tachometer Overflow is detected

Does anyone know what the rg process is? Thank you so much!

Is this still related to the issue you filed weeks ago?

I don’t know what this question is.

Your CPU usage is almost 0% in the screenshot you shared with those processes… Gnome shell took 1.3+0.4 and xorg 0.0 %.
Gnome-shell and Xorg are basically display manager for your Ubuntu desktop…

As for the top, it is more like you are running something in your background and you came back for us to ask what they are … basically we won’t know what you are doing on your side… only you would know.

And for your question. rg is probably the ripgrep. Again, I don’t know what is your purpose to run that with multiple processes.

I think maybe that’s because I use global search in VSCode, where I connect to the Xavier through SSH?

I did nothing in fact. I don’t know why these processes appear as well. Maybe that’s because I use VSCode to connect?

Honestly… I think you should figure this out by yourself.

All right, thank you so much.
