CPU Frequency Scaling

Dose anyone know how to disable CPU Frequency Scaling under the newest Ubuntu? My laptop pauses every time the CPU is scaled, pauses meaning that the mouse stops for a second and if your playing music, that stops as well, but just for a second. I know this saves power but, its stoping me from doing work.

I have a Dell Latitude C600; Kernel: 2.6.12.

Thanks for any help.

well you need to get the kernel source files and extract them to /usr/src/linux. then 'cd /usr/src/linux; make menuconfig' and a menu should pop up with all of the kernel options. Go to "Power Management Options" > "CPU Frequency Scaling" and hit space bar to disable it. then you need to recompile it doing something like "make && make modules_install" and copying the boot image over. "cp /usr/src/linux/arch/x86/boot/bzImage /boot/kernel-custom" and make sure grub or lilo knows the location of the new kernel. Keep in mind you might loose some custom modules if you installed any.

Ah..thank you! I will try this out, um... stupid question but, where can I get the Kernel src from ubuntu package system? When I do an apt-get kernel-src I don't get anything. And a bit off topic, but whats the best wireless card (for a PCMCIA slot) for a linux system?

Thanks agian.
