We can check if the problem lies with the cpufreq-selector utility or with the cpufreq modules.
Remove the CPU frequency scaling applet, and run the following commands: sudo echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor sudo cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq The output of the second command should be 800000? I assume you have no process running which are using much cpu, to check it you can use the ps aux command and look at the %CPU column. All numbers must be very small (0 to 2). -- [feisty] CPU scaling ondemand stay at 100% https://launchpad.net/bugs/99059 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
