New Bumblebee version 3.0 is working out of box. Thanks to https://wiki.ubuntu.com/Bumblebee
For my ASUS K53SV netbook, (NVIDIA GT540M) it is a great power saving too.
With default Ubuntu 11.10 installation, my power consumption was nearly 30~32 W (battery life ~ 1hr and 50 minutes). I managed to cut it down to 22 W with some kernel options before boot using this (http://www.phoronix.com/scan.php?pag...15_power&num=1).
But Still the battery was lasting hardly for 2hr and 40 minutes at even 20% screen brightness.
I installed today Bumblebee 3.0, (had never tried it in past, nor did for Ironhide). After installation and reboot it came down to 12W consumption. Battery is now reading 4 hr and 40 minutes, and mind that the display brightness is at 50%.
I don't use any power tweaks (No Powetop/Jupiter or anything similar).
Default Ubuntu 11.10 64 bit installation
+ Kernel Options(GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor i915.i915_enable_rc6=1 pcie_aspm=force")
+ Bumblebee 3.0
I have tested some of the games on wine, which are working fine with bumblebee "optirum wine yourgame" command.
ONLY Bumblebee has managed to calm down my discrete NVIDIA card, which was by default always ON in my default Ubuntu 11.10 installation, and was consuming alone 10 W of power, cutting my battery down by 2 hours.
@adranielJust let me know regarding exactly what? Installation of Bumblebee or the kernel options? Both are different matters from each other.Could you put all the steps you took please?

12 watts? WOW that's still high, install Jupiter.. With the NVIDIA off, you might see it drop to 6 or 7.I have not even heard of this much for this machine on any site or blog. If you are sure enough, then I will give it a try to Jupiter. Won't Jupiter settings conflict with "optirun myapp" command? What you say?You know what 7 watts mean? It's a dream thing!!! 7 watts would mean (56 Wh) /(7 W) = 8 hours of battery life.
