Undervolting under Ubuntu 9.10?

So I recently installed Ubuntu 9.10 64bit on my M1530 and have a dual boot setup with the other OS being the NSA's Windows 7 64bit. This is my first Linux experience and I am rightfully enjoying it. Thus far I have been able to figure things out OK, but I am a total Linux newbie and dont know of a way to undervolt. I havent figured out if its possible to run RMClock and I dont know of a Linux alternative. Most the stuff I find on google is years old and Im thinking there have been better solutions since then. Does anyone know how to undervolt using Ubuntu 9.10? Thanks.

 

Honestly, your first step to really getting to know Linux would be to use VMware Workstation, Player, or VirtualBox and make a virtual machine to run it. That way, you can boot into Windows all the time, and then fire up your virtual machine(s) and play around. They also use basic hardware so you shouldn't have issues installing virtually any version of Linux, BSD, or Windows on it. Also, you still keep the benefits of using Windows and all the tweaks you're used to.

Barring that, have you also looked into the Ubuntu forums? I used to hang out there years ago and go by there occasionally (I have server and desktop VMs in 9.10) to see what's up.

By the way, since you say you are kind of new to linux you could always try this:

Studentdriver - I dont like to run virtual machines because they open up security holes in your system. I already tired linux with the live cd and liked it enough to go full on dual boot. I had already searched those forums and got some out dated results. There doesnt seem to really be an easy way to do it now without modifying the kernal, which I dont want to do. Thanks.

M1n05_4 - I had found that link, but its over a year old. I was hoping there was an easier way. However, that linux google search is pretty cool, thanks.

 

This may not be relevant to you but...

if your interest is to conserve battery power and keep the computer running cooler so that the fan kicks in less often, then I have found running the program Powertop made an outstanding difference. Without it, I was losing an hour of battery life compared to windows. With it, and running a minimal desktop environment, I can get it running cooler and longer than in windows.

However, it is not an undervolting solution - I think it mainly works to ensure that your chip runs slower, so it's not equivalent and may not be suitable if your interest was keeping the computer cooler while stressed.

Security holes? Well, I've been virtualizing for around 8 years or so now, and I haven't found any consistent ways to compromise the sandbox of any host application. But, if you believe that then that's fine.

Most applications that need to interact with low-level BIOS calls are going to need serious kernel interaction. This will likely involve, at a minimum, compiling the application against your kernel and probably recompiling your current kernel to allow for the hooks.
