Hello, I have a thinkpad x200 (sandy bridge), and I don't think my experience is very typical, but: I saw some of the same power regressions people are talking about, but I stuck with the latter kernels (I'm using 3.0.4 from the mainline site) because the older, energy-saving kernels had some trouble with the sandy bridge chip.
In any case, I was using Natty+Gnome Classic, but a few days I decided to take the plunge and update to Oneiric+Unity, and low and behold, I'm seeing *much better* power performance *with the same kernel I was using before*. With Natty, I could barely get power consumption down to maybe 13 W (no bluetooth or network, etc). As I write this, with bluetooth off but wifi on, the laptop is drawing ~9W, and I still have >6h to go with 65% battery. Suffering occasional unity freezes, so not everything is sunny, but... One difference is that I set all the tunables using PowerTop, and the version that comes with Oneiric has more tunables than the previous one. Now, if I can only make them persistent over shutdowns and suspend/resume cycles... In any case, this is just to say that in my case, not everything is about the kernel... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760131 Title: Power consumption raised significantly in natty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/760131/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
