Does the CPU frequency range monitor not work in Ubuntu?

&http://www.aliyun.com/zixun/aggregation/37954.html ">NBSP; I need to insert a module to allow me to see the CPU frequency range. Ubuntu does not modprobe this module so using "Cat/proc/cpufreq" will not see anything, when inserting "p4-clockmod", I immediately see the result. Therefore, I added "P4-clockmod" to the/etc/modules file, so that each time the boot automatically load. I opened the CPU frequency monitor in the Gnomei and was happy to see my CPU speed. For the rest, Ubuntu uses the "Powernowd"-Program to automatically adjust your CPU frequency. Note: If it is an AMD processor, you will need to add the "Powernow-k7" module to the/etc/modules file. You can view/lib/modules/[your kernel version]/kernel/arch/i386/kernel/cpu/cpufreq directory, and you can see the Cpufreq modules you can use:

Acpi-cpufreq.ko Longrun.ko Powernow-k8.ko Speedstep-smi.ko

Cpufreq-nforce2.ko P4-clockmod.ko Speedstep-centrino.ko

Gx-suspmod.ko Powernow-k6.ko Speedstep-ich.ko

Longhaul.ko Powernow-k7.ko Speedstep-lib.ko

Add your module based on the actual hardware and then use sudo/etc/init.d/powernowd restart to reboot the power-saving function.
