I'm running Ubuntu 14.10 x64 on my Dell XPS 15 9530 laptop. I noticed that my CPU is loaded pretty heavily, although I can't find the process(es) which take(s) these resources.

Processes sorted by % CPU used enter image description here

Can someone please point out a place to look at?`

  • memory isn't a problem, CPU usage is. @MarkWilliams ok, so top shows that kidle_inject takes those resources. It looks like a feature.

  • it seems like you're only showing processes from your own user account, so you're omitting all the processes run by the system and not seeing the whole picture. Try opening a terminal and look at the output of 'top', it will give you all processes of all users by default.

  • Or you can click on the View button in the system monitor and check View All Processes

If your machine is not one of the fastest, I would assume that the system-monitor CPU-graph window itself is eating the CPU time.
I have Intel Duo 2x2.0GHz and I can't get the displayed load below maybe 50% if that graph window is open.

Go to the settings and adjust the refresh delay to 1sec or so. That should make a huge difference, but at least for me, it does not save this setting.

Or check the CPU usage with other tools like top from the terminal or indicator-multiload (usually has to be installed first), which displays a small graph in your panel.

  • Thanks you for the answer. I've figured out that it is kidle_inject that takes these resources.

I found that it's Kidle_inject process which takes my CPU resources.

Thanks all for pointing me the way to see this (command-line Top command, or changing view to "All Processes" in system-monitor).

You can read more about Kidle_inject process problem here.
