I noticed with openSUSE 11.3 and KDE 4.5 that in the power management module you no longer can configure your cpu options to performance/ondemand/powersave. This worked with the 4.4.5 packages.
AFAIK this was a concious decision and if I'm not mistaken, this is the reason: Contrary to common sense clocking the CPU down all the time does not inprove battery life because tasks take longer to calculate. AFAIK the battery life improves when the CPU accelerates while performing tasks to finish them fast and then clocks down once the tasks are done. If you really have to manually set the clock speed for whatever reason, you can assign commands to power profiles and set the speed by executing cpufreq-set from cpufrequtils. -- To unsubscribe, e-mail: opensuse-kde+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kde+help@opensuse.org
