Having the same issue on Precision 5520. Started happening after upgrade form 16.04 to 18.04 as well. I don't have Synaptic drivers installed, using libinput.
Running the same kernel as for 16.04, 4.16.18-041618-generic installed from http://kernel.ubuntu.com/~kernel-ppa/mainline/ What kind of logs would you need to help debug this? -- 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
