UPDATE: Solved by disabling bluetooth in bios according to:
https://askubuntu.com/questions/1028883/ubuntu-18-04-systemd-udevd-uses- high-cpu-conflict-with-wifi It is silent and cool now. Under the link you can find guys saying that this systemd-udevd 100% cpu usage is because of the dell bluetooth. Others might have similar issues with this. There is a probable solution here too if you want to use your bluetooth too. I didn't try it though. In summary: blacklisting nouveau, installing nvidia driver and disabling bluetooth solved the overheat problem for me. I feel this is a workaround though, and linux shouldn't overheat in any case. -- 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
