Same for me: ubuntu 18.04 just installed on Dell Precision M3800. Before I was on 16.04 and CPU temp during normal session was about 47-55 deg.
Now, it's constantly at 63-80 deg. I tried lots of tweaks (install thermald, tlp, cpufreq-selector, etc). Nothing worked until now. I'm seriously considering to go back to 16.04, or switch to anything else that would not slowly kill my hardware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768976 Title: Ubuntu 18.04 is overheating after upgrade from 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1768976/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
