Hi, Adam. Gnome System Monitor by default does not divide CPU usage by the number of cores available - In your case, it was fully utilizing the equivalent of more than one core.
This could have been one full core and some of another, or just part of each core. To change this to show a more 'Windows-like' number, you can go to Edit -> Preferences -> Processes -> Divide CPU usage by CPU count. Thanks for reporting this anyway :) ~Cruz ** Changed in: gnome-system-monitor (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/989866 Title: System monitor showing inaccurate CPU% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-system-monitor/+bug/989866/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
