Followed instructions from #67. Running 'cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver' to check for frequency scaling driver shows 'acpi-cpufreq' instead of 'intel_pstate', even *before* adding 'intel_pstate=disable' to /etc/default/grub.
After adding 'intel_pstate=disable' to /etc/default/grub and rebooting, 'cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver' shows 'acpi- cpufreq' as frequency scaling driver, too. In my case, using kernel 4.15.0-45-generic, 'intel_pstate' frequency scaling driver has never been shown as active, yet the processor overheating continues. My laptop's processor is an Intel i5-540M @ 2.53GHz, to be precise: https://ark.intel.com/en/products/43544/Intel-Core-i5-540M-Processor-3M-Cache-2-53-GHz- Video is NVidia Quadro NVS3100M with binary driver 340.107: https://www.nvidia.com/object/nvs_techspecs.html -- 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
