Turning off Nvidia GPU on Asus N53SV laptop. Nvidia Optimus. Installed Bumblebee
Linux eats eats my laptop's battery for breakfast.
Laptop: Asus N53SV with 2x 8GB DDR3 and 2 memory slots free. With the standard 750GB 7200RPM hard drive and DVDRW. Distro: Mint 15 x64 with Mate 1.6 Kernel: 3.8.0-19 kernel On a fresh boot powertop reports 44W used. It settles down after a few seconds to 23W. I used this kernel module to turn off my GPU with the command: \_SB.PCI0.PEG0.GFX0.DOFF Powertop reports power consumption drops to 11.3W. All seems well. But when I try shut down the system crashes (Mate GUI freezes and the hard drive light stops blinking) I tried repeating the test, turning the GPU back on using the command \_SB.PCI0.PEG0.GFX0.DOFF, but power consumption only rises to 18W meaning the GPU is not restored to its original (power hungry) state. Shutting down STILL crashes. I verified that if I boot up, run powertop, wait for system to settle and then shut down, there are no problems. =================== The next idea I had is to shut down in a terminal or see if there is some error message, whats the best way to do that? Beyond that I'm out of ideas. What do you suggest? |

Asus N53SV with an nVidia GPU? If so, its an 'optimus' setup and I'd suggest trying Bumblebee, not vga-switcharoo.

I was hoping someone could suggest what log files I should check or what method to use to shut down, where I'd be able to see an error. cascade9: Ok, I thought bumblebee was for using the Nvidia graphics. I don't want to use the Nvidia graphics at all. (at this stage) so I thought the ACPI stuff was the way to go. |

Cool, thanks will give bumblebee a try :)
I was a little hasty when I went through the installation. I didn't read the whole page and see that there is an option to JUST get the power management. https://wiki.ubuntu.com/Bumblebee#Installation For better or worse I'm getting the whole bumblebee open source nVidia story. (500MB of archives) Perhaps I'll find a use for my GPU. |
Thanks cascade9!
I installed the full bumblebee package. Rebooted. Had to re-configure my resolutions. Then I ran powertop and saw my GPU is automatically switched off. My laptop was idling at 13.5W :) Awesome! Then I shut down and it didn't crash! weeeeeee! |
