CPU clock

[Flynn]

I have a Dell laptop on which I recently installed Gentoo on. Everything is working great except that after a couple of minutes of use things become unbearably slow. I know that Dell has some sort of control on their laptops which is supposed to clock them down when they are idle or running on battery power to save life, but frankly, this control sucks a lot of dick. On my other Dell laptop which has Windows on it I run RMClock to keep the clock speed at maximum at all times or else it just clocks down to about 400 mhz, even when on AC power and running several applications at once.

Before installing Gentoo I had Ubuntu on this laptop and never noticed any slow downs. So I think this can be somehow fixed. I just need to know what I need to emerge, which conf file to edit, what to enable/disable in the kernel to either disable this control outright, or at least give me a Linux equivalent of RMClock so I can set the clock speed manually.

I have a Dell laptop (600M) and I'm not sure if you're seeing what I'm seeing. Whenever I run at full speed on AC power for both CPU and GPU the machine would get really hot, and the machine will kick into power saving mode to prevent itself from burning up. This may be a good thing, I don't know. It's definitely annoying.

It sounds like your machine may be using more power for some reason or other.

I've not seen this behavior yet in Linux on my Gentoo installation, but it frequently happens in Windows while running World of Warcraft. I've yet to get WoW to work in Linux as it would probably be the most power consuming application that I have and provide an apples-to-apples comparison...
