I have the same heating issue after a clean install of Ubuntu 18.04. Before that I was using Ubuntu 16.04, without this problem.
Fans are more active than before and the laptop is constantly overheated, with 70-80 degrees doing nothing but only Chrome or even with the shell opened. Nvidia drivers has been removed (I can live with the integrated Intel). Kworker issue (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/887793) already fixed. This happens on a Samsung 7 Chronos NP700Z7C (CPU i7 3rd gen) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in 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/ubuntu-release-upgrader/+bug/1768976/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
