    Hrrm, I'd say that's fairly accurate--messy at the mometn. Hopefully, it will soon be straightened out so that reasonable power management, Selentic touchpad and other issues will just work out of the box. Might take a little while though.

    Yes, it is confusing at present. The summary page is good--this thread gets a bit out of hand, as it's such a long thread. I usually check once a day, go to the last post and work backwards.

    We are back to either enable or disable, but it works, am I right?

    And to save everyone a little guesswork: with the 3.3-rc5 kernel, the first patch mentioned in the linked post above is already applied, the second one (operator precedence) is not.
    The patch that allowed to choose the RC6 activation level was never intended to be ported on 3.2 nor 3.3. It leaves in drm-next and will certainly be merged for 3.4.

    Still with 3.3-rc5, Eugeni Dodonov did send a patch that, when the kernel is booted with i915.rc6_enable_rc6=1, will only enable shallow rc6 so the sandy bridge owner won't suffer hard shutdown.

    But this patch (which is included in 3.3-rc5) was messed up (an operator precedence issue was causing rc6p, the level that make snb machine to crash, to be allways activated). So you still need the last patch posted by Eugeni which will basicaly fix the fix.

    I personally (I obviously am not Linux Torvalds) expect the final fix for 3.3 to be merged for the next RC.

    All of that is if you roll your own kernel right from the source. The Ubuntu-kernel team has already picked all the necessary patch (and I believe that rc6 is also enabled by default) so if you use a kernel from them, you should have nothing to do to enjoy 6 hours long trip without charge with your Zenbook.

    Hope it was clear this time.

    Has anyone faced a shutdown when unplugging AC Power ?
    For me it's the most annoying issue. Sometimes when I unplugged the Ac Power the laptop shutdowns immediatly.

    Never.. though some in this thread have. I can't recall why this issue went away for those folks though.

    What are you running? We'd probably would need to know the kernel version, if you've got any of the power scripts mentioned in this thread (a suspend related script and an "efficiency" powertop script), and if you are enabling rc6 in your boot parameters.

    Hi everyone,

    I'm following this thread since its beginning and it makes me learn very interesting things !

    I can reproduce easily a shutdown (kernel 3.3rc4 + rc6 patch, same since 3.2) :
    - on AC or on battery, doesn't matter
    - high activity on wifi (like dl a distribution (...) with transmission at ~1.2Mb/s) -- it doesn't occurs on usb/ethernet
    - as soon as my screen fade out to black, either a freeze or a kernel panic occurs.

    I thus suspect a problem with ath9k suspend or else...

    I once did this:
    Fixed the usb-ethernet (see wiki) while on the live CD. Installed Ubuntu. Updated the kernel.

    Maybe you could try that...

    Re: Ubunutu and the asus zenbook (UX31)

    Hello everyone, I just skimmed through this gigantic thread, but I didn't see anyone having the same problem, so any help would be appreciated:

    I installed Ubuntu 64 bit (dual boot with w7) and did everything the wiki told me to (upgrade kernel to 3.2.2 etc). Everything seems to work fine except for the elantech touchpad, it's still unresponsive and multitouch scrolling doesn't work. Tapping with 2 fingers does nothing, but 3 fingers brings up window resizing buttons. I added Aurélien Jacobs' script to /etc/rc.local, so is there anything else I'm missing? Possibly noob mistakes? (Also, is it normal that the touchpad doesn't respond to using just one's fingertip?)

    Thank you!

    I have you configuration in an UX31 with elantec touchpad. I experienced very few shutdowns, booth in AC or battery, and always when the use is relatively intense (graphics manipulation, for example). It seems not have relationship with the use of wifi. In any case, the wifi signal is relatively weak compared with other computers at the same distance of the router.

    Cheers

    Kernel panic/freezes is not what we call shutdowns and has nothing to do with rc6.

    The wifi driver is buggy. I get a lot I get the freezes too.
