When will this come for ubuntu ?

I am getting tired with my 11.10 dieing at little over 50 minutes of battery when at the most extreme powersaving plan.

  • I am also waiting for this patch to be confirmed by Canonical. This battery/overheating issue has got to be solved

  • Excuse me if I'm missing something, but this doesn't seem like a dupe to me. The answer below seems to suggest otherwise to me. Nov 14, 2011 at 7:16

    Please don't just ask the same question again, the patch will be published as soon as enough people test it and the kernel team is confident that it works. Nov 15, 2011 at 0:06

Hopefully, the patch will make it into the 3.0.0-13 kernel update for 11.10. You can help testing.

https://wiki.ubuntu.com/Kernel/PowerManagement

PS: ...and if you don't want to wait, apply the relevant workarounds now. Note, some of the workarounds are only relevant for Intel GPUs.

http://www.omgubuntu.co.uk/2011/11/linux-power-regression-overheating-problem-on-thinkpad-fixed/

Example

To add the pcie_aspm option, open /etc/default/grub for editing with
gksudo gedit /etc/default/grub

find the the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and change it to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force", save and exit.

Then run sudo update-grub.

You can also verify whether Active State Power Management is enabled or not with
dmesg | grep -i aspm

  • Please could you edit your answer to include the relevant workarounds like where and how to tweak the Grub config?

  • Done! Let me know how it goes. Nov 14, 2011 at 7:11
  • excellent answer +1 - just to say - this AU question and answer is still relevant to oneiric for intel users - askubuntu.com/questions/38117/…

  • I'm sorry but this patch refers to the old patch Phoronix released the new patch i915.i915_rc6=1 which they claim as a fix and not a workaround. I can verify that this patch( your answer) does not solve the heating/power bug. Could you please edit your answer with the new patch PLEASE

A kernel update is due after the SRU tickets have tags changed from "testing-needed" to "testing-done" (after testing has actually been done.)

To find the SRU tickets try looking on this web page:
http://people.canonical.com/~ubuntu-archive/pending-sru.html

For 11.10 switching from 3.0.0-12.20 to 3.0.0-13.22 requires verification of the following tickets:

#737388 #782389 #794642 #816484 #851697 #854399 #854468 #855239
#857297 #860868 #862583 #865171 #866021 #868628 #870127 #872711
