    Okay, I think what I was missing from Jupiter was the cpufreq stuff. For those who are interested, you can bypass the need to install Jupiter and have automagical better power management with the open source drivers on battery by doing the following.

    Download this script then copy/move it to /etc/pm/power.d/1-apu and give it executable permissions via sudo chmod +x /etc/pm/power.d/1-apu.

    It will set things to use dynamic power management for the video and ondemand for the cpu when plugged in, and switch to low profile and powersave respectively when on battery.

    This is preferred for me since I would rather not install a GTK mono program such as Jupiter on my Kubuntu, plus this has the niceness of transparency and automation. If Jupiter does anything else important that I should add to that script, let me know.

    EDIT: Removed steps which I found were unrequired and updated the script to change cpufreq details without needing cpufreq-utils. Also includes an extra power management option recommended by lesswatts.org. Cheers.

    UPDATE: That script should more than suffice for people who share a lack of interest in using mono gtk software to control their power settings. A test of Fuduntu with Jupiter on powersave compared to my typical Kubuntu install (no effects in KDE and using plastic theme) both reported the same; around 5+ hours of battery. Using Kubuntu for taking notes via KWord in class gave real world support to the claim as well, as I only lost about 20% battery in 1:20 or so.

    Zzarok, thank you so much for this post! I used this for Linux Mint, and the only thing that I had to change was the method for installing Jupiter (http://www.webupd8.org/2011/09/jupit...lable-for.html)

    Unfortunately, my work schedule still doesn't allow me to sit down and test all fixes for vanilla 11.10 (it took me a few days of searching and testing for the original post). I'm currently quite annoyed by several bugs in 11.10 (I reported them, or joined watch list if they were already reported, but it seems that all canonical developers are making new Unity features, but almost none is fixing existing bugs) and I'm thinking about Mint... Anyway, I hope I will have the free time before NY.

    Hard disk clicks when on battery

    Did any of you experience hard disk clicks when running on battery? On my 722 they were regular, about once in 10 seconds, and for a long time I assumed this to be normal. And today I looked at:
    https://wiki.ubuntu.com/DanielHahler/Bug59695
    It seems that Ubuntu was trying to spin-down HD too often, and because the HD was in use, it was spinned-up immediatly after. I applied the proposed fix (hdparm -B 254 /dev/sda) and the clicks were gone! I just hope this didn't damage my hard disk too much...

    No it won't, it's missing more than half of the power saving tweaks found in Jupiter.

    Jupiter's Mono GTK applet is just a configuration and reporting tool. You can delete it from the filesystem and Jupiter will still function (you just won't be able to configure it easily).

    I'm confident that if you measure the actual run time of Kubuntu with your script vs Fuduntu with Jupiter you'll find that Fuduntu will by far outlast Kubuntu.

    Okay I shall look at the source and add the missing tweaks then. Thanks for the heads up.

    Meh, that or you could just use Jupiter which has already has a few years of maturity under its belt.

    Mono and gtk dependencies aside, it still did not even properly run under Kubuntu as it had errors trying to run. Besides, this also uses existing freedesktop standards (http://pm-utils.freedesktop.org/wiki/), which also has some years of maturity behind it.

    For the interested, the other tweaks for /etc/power.d/ .

    http://pastie.org/2967787

    - Save as /etc/power.d/2-misc and give permission to execute.

    Also, an updated /etc/power.d/1-apu

    Uhh, Jupiter plugs into power.d, that's how it works. I also know of several people that use it under kubuntu without any issue.

    Good luck supporting this.
