Battery Life and CPU Temperature in Linux

[IcedEarth]

Hi

Does anybody have any experience with Ubuntu on an X60 tablet?

I have Ubuntu 8.10 installed and I notice that the CPU Temp is about 50c. I have also noticed that the battery life is shorter.

Its a real shame that Adobe Player doesn't perform as well in Linux as Windows, the CPU works a lot harder in Linux.

Shame on Adobe, shame on Linux!... XP forever (actually till 2011)... There are substitutes to Adobe player

A friend of mine has a X60 tablet with Ubuntu (not sure if 8.04 ot 8.10) installed, yes it runs somewhat hot and has shorter battery life. Take a short look in improve battery life on linux.

Cheers

Unfortunately, Linux is currently not optimized for power consumption. Tools like powertop can help, but I don't think it's enough.

With Windows, I can also control the cpu speed and cpu power usage better. In Linux it involves more complicated set of steps.

I'm a big Ubuntu fan, but I only use it on my desktops and always plugged in X22.

On the contrary you have more control in linux than in windows. You can control everything from HDD spin down time, brightness/screenblank, power to wifi, fan speed etc. Heck you can even load the entire OS in a RAM (Ramdisk) and shut down your disk for good. My x61 runs about 30 mins longer in Linux than it did in Vista (OEM installed).

Install laptop mode tools and edit your /etc/laptop-mode/laptop-mode.conf accordingly. Use a lightweight window manager and dump Gnome/KDE.

To control fan speed look here http://www.thinkwiki.org/wiki/How_to_control_fan_speed

With proper scripts and some of your time (few mins) everything can be automated.
