Public bug reported: After installing powernap on a Ubuntu 11.10 Server system, and possibly only after a subsequent reboot, I found the system to be running with the "performance" scaling_governor, which was a change from the original behaviour where the system would have the "ondemand" governor by default.
Resetting the scaling_governor to "ondemand", either via calling /etc/init.d/ondemand or by manually echoing the setting into /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor, was temporarily succesful, but after about a minute the scaling_governor would again be found set to "performance". I believe the problem may be in /etc/pm/power.d/cpu_frequency, which doesn't seem to know about /etc/init.d/ondemand, but I'm afraid I don't know enough about upstart et al to suggest a good fix. Thanks for powernap, and thanks for reading! ** Affects: powernap (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/892609 Title: powernap reverts cpufreq scaling_governor setting to performance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/powernap/+bug/892609/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
