OK, I think I got it...well at least for you guys having speed stepped Intel CPUs:
just edit '/etc/cpufreqd.conf' and make sure that the settings are correct. For me the default settings were ## # Basic states ## # when AC use performance mode [Rule] name=AC Rule ac=on # (on/off) profile=Performance High [/Rule] [Rule] name=Movie Watcher programs=xine,mplayer,gmplayer battery_interval=0-100 acpi_temperature=0-60 cpu_interval=0-100 profile=Performance High [/Rule] This sucks. So I decommented the ondemand options and choose them instead:[Profile] name=On Demand High minfreq=40% maxfreq=100% policy=ondemand [/Profile] [Profile] name=On Demand Low minfreq=20% maxfreq=80% policy=ondemand [/Profile] [Profile] name=Performance High minfreq=100% maxfreq=100% policy=performance #exec_post=echo 8 > /proc/acpi/sony/brightness [/Profile] ## # Basic states ## # when AC use performance mode [Rule] name=AC Rule ac=on # (on/off) profile=On Demand High [/Rule] # stay in performance mode for the first minutes [Rule] name=AC Off - High Power ac=off # (on/off) battery_interval=70-100 #exec_post=echo 5 > /proc/acpi/sony/brightness profile=On Demand High [/Rule] # conservative mode when not AC [Rule] name=AC Off - Medium Battery ac=off # (on/off) battery_interval=30-70 #exec_post=echo 3 > /proc/acpi/sony/brightness profile=On Demand High [/Rule] # conservative mode when not AC [Rule] name=AC Off - Low Battery ac=off # (on/off) battery_interval=0-30 #exec_post=echo 3 > /proc/acpi/sony/brightness profile=On Demand Low [/Rule] ## # Special Rules ## # CPU Too hot! [Rule] name=CPU Too Hot acpi_temperature=55-100 cpu_interval=50-100 profile=On Demand Low [/Rule] [Rule] name=Movie Watcher programs=xine,mplayer,gmplayer battery_interval=0-100 acpi_temperature=0-60 cpu_interval=0-100 profile=On Demand High [/Rule] -- CPU Frequency Scaling defaults to "Performance" instead of "OnDemand" https://bugs.launchpad.net/bugs/344252 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
