Unable to switch off NVIDA card via bbswitch on Thinkpad T540p

[oliverwelter]

Hello, I'm trying to use bbswitch-0.8 for turning off the GeForce GT 730M on a Lenovo Thinkpad T540p. The state shown in /proc/acpi/bbswitch stays on 'ON' independent of load_state and manual setting. The power consumption supports the suspicion that the card is still running.

cat /etc/modprobe.d/bbswitch.conf:
options bbswitch load_state=0 unload_state=1

I also tried to switch off manually: 
cat /proc/acpi/bbswitch:
0000:01:00.0 ON

tee /proc/acpi/bbswitch <<<OFF:
OFF

cat /proc/acpi/bbswitch:
0000:01:00.0 ON

dmesg | grep -C 10 bbswitch:

@toxictee Does the solution at #112 help?

[ghost]

@gsgatlin Thank you, I tried this solution before. I thought the power usage is still to high, but it seems this is normal. But I still have an unfixed problem. On my screen are some flickering white pixels (like when you don't have a signal with your television - the white a black points, but in my case only the white ones). When I use save graphic mode at the os install everything works fine, but when I use the normal graphics installer or login after the install I get this flickering white pixels / points on the screen. Does anyone know this problem and how to fix it?

[ArchangeGabriel]

I’m marking this as a duplicate of #112. We definitevely have an issue since kernel 3.15 or 3.16 that probably started advertising Windows 2013 OSI by default, which resulted in some changes for _DSM methods.

[ArchangeGabriel]

@toxictee Also, no idea bout your latest issue, but if it’s related to normal rendering, the issue must lie on Intel/Mesa side.

Same issue, ThinkPad W541, running Manjaro.

Hi all.

I am still having issues with this. bbswitch always shows the card as ON. I am on a T540p.

Here is my dmesg output :

I tried this : (found here : https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=763272)

The workaround given was to append acpi_osi=\"!Windows 2013\" to the GRUB_CMDLINE_LINUX_DEFAULT variable in /etc/default/grub and run update-grub.

It has not changed anything.

I am on 4.8.4-1-ARCH

I am super lost in this. Thanks. JP

[Quardah]

Hi all.

I tried as mentionned the "acpi_osi=!Windows 2013" argument, it didn't do anything. I tried also adding "acpi_osi=Linux" argument as boot param, it made it impossible to load the "nvidia" kernel driver.

Now i took both down and i'm pretty desperate.

I'll have to stick with my old laptop until i can turn off this stupid card.

Thanks for your help, hopefully someone will enlighten me i am out of clues.

EDIT :

This might help :

Somehow the device is "refusing OFF" because it's used by nvidia?

But where? I have no clue where to check.

This is painfull really u_u

[jeannotalpin]

Using Ubuntu from now on, adding the below parameters to the booting lines and configuring correctly the bumblebee.conf file, I have the correct behaviour for bbswitch. "acpi_osi=!Windows\x202013" acpi_osi=Linux nogpumanager Hope it helps, Jean.

[haffenloher]

The only thing that helped me turn off my card is altering akmods.service as described here: https://github.com/Bumblebee-Project/bbswitch/issues/120#issuecomment-180095778

[Quardah]

Thanks to both of you.

I will try to add the lines in my boot parameters, i'll come back to tell you if it worked.

Also, i do not having akmods.service. (Runnning on Arch Linux, doesn't seem to be in there).

Thanks

[Quardah]

Holy shiiiiiiiiiiiiiiiiiit jeannotalpin that worked

thanks mate that's really appreciated. Now is 23:25, i have been trying to fix this since 10:30 in the morning.

Thanks man you're a life saver.

Hopefully someone will read this and this will help them

Cheers!

[ph03]

Awesome @jeannotalpin, that kernel parameter line is working for me on Ubuntu 16.10 4.8.0-30-generic W541 as well, thank you, I can finally turn of the dGPU again :+1:

[afro-coder]

@ph03 the kernel parameters go in grub cmdline right?

[Quardah]

@leon9923

Yes.

Either add into /etc/default/grub like this : (and run "# grub-mkconfig -o /boot/grub/grub.cfg" after)

GRUB_CMDLINE_LINUX_DEFAULT="quiet 'acpi_osi=!Windows\x202013' acpi_osi=Linux nogpumanager intel_iommu=on"

Or while booting in grub press "e" to add cmdlines (won't persist after reboot, best for testing)

[afro-coder]

Does this still work? @Quardah It messed up the rollback drivers also in my system.

[Quardah]

@leon9923

Yes it works right now on the T540p.

[kieselnb]

Huge shoutout to @oliverwelter for the acpi_osi command line arg. dGPU is actually turning on/off with bumblebee and I get much better battery life

W540, 4.8.13-1-ARCH Changed in /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi='!Windows 2013'"

[jdevelop]

Helped me a lot, thanks @jeannotalpin !
