Bug Description

Hi all,

I was installing Ubuntu Hardy LTS yesterday and had some issues whit frequency scaling. What I wanted to do was enable the conservative governor and be done with it.

I tried both setting the governor with /etc/sysfs.conf (after installing sysfsutils) and setting it "manually" with /etc/rc.local. But everytime I booted I ended up with the ondemand governor (which for some reason doesn't work properly on my laptop). I also disabled powernowd but that didn't help.

When I echoed conservative into the scaling-governor file it did change, though. But when I disconnected my ac adapter it went back to ondemand. Plugging the ac back in it was changed to performance.

Somehow it doomed on me that this was the handy-work of hald-addon-cpufreq. After removing the file 10-cpufreq.fdi from /usr/share/hal/... it wasn't loaded anymore and my issue was done with.

Given that Ubuntu by default uses powernowd (which apparently changes the governor as well) I think this should be the default (hald-addon-cpufreq shouldn't be loaded) as it's going to interfere with any other application that changes the cpufreq governor.
