@Colin: I agree with all of that. Our kernel-side default is not powersave, but performance, across generic and oem, at the very least:
$ grep CPU_FREQ_DEFAULT_GOV_.*=y /boot/config-5.* /boot/config-5.4.0-26-generic:CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y /boot/config-5.4.0-42-generic:CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y /boot/config-5.6.0-1018-oem:CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y /boot/config-5.6.0-1020-oem:CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y We used to set that to powersave (and ondemand on non-pstate) in ondemand.service, but have since removed the service in groovy. I believe the default governor kernel-side outside Ubuntu is usually CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND, which translates to ondemand pre- pstates, and powersave on pstates (compare Fedora), whereas Enterprise systems usually pick PERFORMANCE too (compare RHEL) - probably because most distributions focus on normal end users and enterprise on server and workstation. We don't have that distinction of course, so I'm not sure what the best way out is - default to powersave/ondemand and make server installer write performance - or vice versa default to performance and make ubiquity configure powersave for desktop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1885730 Title: Bring back ondemand.service or switch kernel default governor for pstate - pstate now defaults to performance governor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1885730/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
