How/Where do I check my ubuntu laptops's CPU usage?

  • Additionally, try out this page for more information. This is very comprehensive and surely answers a lot of queries, although I personally feel using system monitor is the best solution. – Arnab Sanyal Nov 13 '16 at 14:02

  • Why is this the accepted answer when an earlier answer provided a faster builtin solution? This answers questions that weren't even asked. – deanresin May 16 '18 at 5:21
  • @deanresin I completely agree with you. But if you know how to use htop then you will know how to monitor each CPU core performance. Thank you. – rɑːdʒɑ May 16 '18 at 9:50
  • If F10 does not quit htop but shows some menu, as prompted at bottom, press q or ctrl - c to exit. – themefield Sep 29 '18 at 15:33

In your dash i.e. pressing super key search for system monitor application.

If you are comfortable with command line there are tools like top and htop where cpu usage can be viewed as well.

As said in previous answer you can use system monitor which is the best tool. If you want more information you can try some commands on terminal

top - its a command to see all the processes and their CPU usage. Just read the screen carefully and you would find lot of other useful information there. you can press Ctrl+c to close it.

Or you can also try cat /proc/cpuinfo - for other information about cpu

    You can also quit top by simply pressing the q key – Attila Fulop Aug 10 '13 at 7:42
