How to disable nvidia card on my Dell XPS 15z ?

[Benruk]

I installed the latest version of Bumblebee, now I can use games but I can't disable the nvidia card. I use GT 525M 1G.

Same here. Got the nvidia card working, even got pyrit with cuda working.
The problem is how to shut down the nvidia card to save some power while mobile.
I tried the acpi_call method, but it did not work.

The same for me, I've got XPS15z L511, but I can't shut down the nvidia card. Hope you can give us a method acpi_call that works just for our PCs.

Note useful archangeGarbriel.
I used this guide: http://hybrid-graphics-linux.tuxfamily.org/index.php?title=ACPI_calls#How_to_add_your_model.27s_information
but the test report all failed. Cant find our right ACPI_CALL

[Bruno Pagani]

Then, still in our Wiki, follow the procedure at ACPI page, and mention in your mail that you're not having any calls at all, in that way we will try to answer you as soon as possible with the accurate calls.

Solved, thanks archangeGabriel!
Here we are the ACPI CALLs

Enable:
[...]
echo _PS0 $(acpi_call "_SB.PCI0.PEG0.PEGP._PS0")
modprobe nvidia

Disable:
[...]
echo _DSM $(acpi_call "_SB.PCI0.PEG0.PEGP._DSM {0xF8,0xD8,0x86,0xA4,0xDA,0x0B,0x1B,0x47,0xA7,0x2B,0x60,0x42,0xA6,0xB5,0xBE,0xE0} 0x100 0x1A {0x1,0x0,0x0,0x3}")
echo _PS3 $(acpi_call "_SB.PCI0.PEG0.PEGP._PS3")

By the way, I'm encouraging all of you to switch to the new versions of Bumblebee, this one is no more developped.

Now it works with the last version, thanks!
