An update. After some digging the conclusion I is that the problem in my case is not linux but might be the Asus BIOS. Even just enetering the BIOS the CPU temperature is rising up to 70-80 degrees. I'v e also upgraded the BIOS, but without significant improvements.
I have the impression the BIOS has problems in dealing with the intel turbo boost technology of my i7-8th generation. Disabling the turbo from linux side (I couldn't from the BIOS) the temperatures of my laptop are now fine. -- 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/linux/+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
