There was NO file /etc/default/powernowd Therefore, I made a fresh install and still there is NO such file. Fortunately this time it loads the ondemand governor.
I checked in packages.ubuntu.com for powernowd and there is no mention of the file /etc/default/powernowd You can close the bug as I cannot reproduce it. -- powernowd uses "performance" as default scaling governor https://launchpad.net/bugs/69287 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
