I've noticed the same thing on Ubuntu 20.04. That is, 4 cores but reports only one enabled -- even when they are all "working hard".
Also, sudo lshw -version just reports a "blank line", no version number. The installer says that I have lshw version 02.18.85-0.3ubuntu2.20.04.1 HTH -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1714570 Title: enabledcores=1, but all 4 cores are online To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lshw/+bug/1714570/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
