Luis, for me hal changes the CPU freq scaling governor too. However, you cannot edit the file /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor until you are in a root environment (sudo will not work). So, to edit the file, just type: sudo -i echo "powersave" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Remember that you have to do this for all your cores.
To automate the process you can append that lines to your power-switch scripts. So we have: /etc/acpi/ac.d/power-switch.sh containing: hal-set-property --udi `hal-find-by-capability --capability ac_adapter` --key ac_adapter.present --bool true echo "ondemand" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor echo "ondemand" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor /etc/acpi/battery.d/power-switch.sh containing: hal-set-property --udi `hal-find-by-capability --capability ac_adapter` --key ac_adapter.present --bool false echo "powersave" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor echo "powersave" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor Anyway, probably the best way to configure your CPU freq scaling policy is through the guidance-power-manager so you can easily change it later. To do that, just click with the left mouse button on the guidance-power-manager icon in you system tray: a configuration panel will pop up. (I configure my policies through the guidance-power-manager and it works well with hal) Hope it helps. -- [Hardy] Guidance-power-manager doesn't know when laptop is mains unplugged https://bugs.launchpad.net/bugs/213128 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
