gedit /etc/thermald/thermal-cpu-cdev-order.xml <CoolingDeviceOrder> <CoolingDevice>cpufreq</CoolingDevice> <CoolingDevice>rapl_controller</CoolingDevice> <CoolingDevice>intel_pstate</CoolingDevice> <CoolingDevice>Processor</CoolingDevice> <CoolingDevice>intel_powerclamp</CoolingDevice> </CoolingDeviceOrder> I tested with the following orders, both woked fine: rapl, pstate, cpufreq cpufreq, rapl, pstate -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1389077 Title: [HP ProBook 4530s] Intel Powerclamp is Slowing CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1389077/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
