Hello,

Did you know if your solution could work with my version of MBP ? Also did you know if there is a way to use the MBP with bumblebee ? My only way to make X works till now it's with the nvidia nouveau module... I tried your tool and I get an error:

./gpu-switch -i

./gpu-switch: line 44: printf: write error: Invalid argument

So I tried to type it in shell:

printf "\x07\x00\x00\x00\x01\x00\x00\x00" > "/sys/firmware/efi/efivars/gpu-power-prefs-fa4ce28d-b62f-4c99-9cc3-6815686e30f9"

and got:

bash: printf: write error: Invalid argument

The efivar exist and the gpu-power-prefs exists too...

Allo someone is here ? 10 days commonnnnnnnnnnnnnnnnn

ah- commented 8 years ago

Hi, what are you trying to do exactly? What does work already and what doesn't?

Have you tried running it as root?

0xbb commented 8 years ago

Hi @dummys I wasn't in front of any computer. I think it would be good if you could answer @ah- 's questions.

dummys commented 8 years ago

What I'm trying to do is switch the gpu. For now I can successfully boot with the grub tricks and disable the discrete. Basically I want to have "two" boot option, one with Discrete on and one with discrete off.

For now I'have a "working" setup with grub and nomodeset i915.modeset=0 nouveau.modeset=1 and with a xorg.conf.d/10-nvidia.conf. But I need to stop lxdm.service, then modprobe nouveau, sometimes in freeze, sometimes not, then type startx. And I have the X coming.

With the intel mode boot, I have nothing to do, lxdm comme directly without problem.

And yes of course I have typed the command as root.

0xbb commented 8 years ago

@dummys so it seems you got GPU switching working, but you are having troubles with the X drivers?

You could check the output of cat /sys/kernel/debug/vgaswitcheroo/switch to be sure you booted with the right GPU.

dummys commented 8 years ago

Nop it's not working... I need to do it all manually. I have no vgaswitcheroo/switch in the folder debug. Which kernel module do I need to have it ?

0xbb commented 8 years ago

Is your Macbook even booted in EFI mode? (check with: dmesg | grep -i efi). I think you can still ask directly here https://github.com/ah-/gmux-scripts/issues/1

dummys commented 8 years ago

yes it's booted in uefi.

OK, I can also only ask @ah- . Otherwise I can help you, because I have no MacBook availble for testing here at the moment.

dummys commented 8 years ago

Ok. If you need testing something, just tell me.

ah- commented 8 years ago

Can you paste a full dmesg?

dummys commented 8 years ago

yes here it is:

If you want anything else let me know. I know this is an older device but I can help with testing as well if you need it.

Hello, I have the same issue on a MPB 6.2 (+ broken discrete hw) and Ubuntu 14.

uname -a
Linux NumeriqueOrganique 3.19.0-51-generic #58~14.04.1-Ubuntu SMP Fri Feb 26 22:02:58 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

I got somewhat further digging into this, but no success... [This thread might be useful](), anyways, the issue seems to comes from writing and/or reading from /sys/firmware/efi/efivars/gpu-power-prefs-fa4ce28d-b62f-4c99-9cc3-6815686e30f9.

Using echo instead of printf didn't change anything. Even hexdump gives the invalid argument error. hexdump: /sys/firmware/efi/efivars/gpu-power-prefs-fa4ce28d-b62f-4c99-9cc3-6815686e30f9: Invalid argument

Any ideas on how to get past this point ?

FYI you can use the techniques mentioned here to get ubuntu working on your MBP 6,2 using only the integrated GPU:

http://forums.fedoraforum.org/showpost.php?p=1664873&postcount=10

Here are the steps I took, adapted from there:

edit /etc/default/grub and add the following line:

GRUB_PRELOAD_MODULES="iorw"

I also changed this line in the same file:

GRUB_CMDLINE_LINUX_DEFAULT="i915.modeset=1 nouveau.modeset=1"

Change this in /etc/grub.d/10_linux:

cat << 'EOF'
function gfxmode {
        set gfxpayload="${1}"
EOF
if [ "$vt_handoff" = 1 ]; then

to this:

cat << 'EOF'
function gfxmode {
        set gfxpayload="${1}"
EOF
echo " outb 0x728 1"
echo " outb 0x710 2"
echo " outb 0x740 2"
echo " outb 0x750 0"
if [ "$vt_handoff" = 1 ]; then

Here's what those do btw:

 outb 0x728 1 # Switch select
 outb 0x710 2 # Switch display
 outb 0x740 2 # Switch DDC
 outb 0x750 0 # Power down discrete graphics

Also you need to run this to update grub, and then reboot:

sudo update-grub
sudo /sbin/shutdown -r now

This is literally ALL I needed to do. I had installed 10.12.4 previously, which updated the EFI firmware, so I also reset my NVRAM with the command-option-P-R trick after rebooting to make sure there weren't any EFI variables left over which might be screwing with the framebuffer and GPU settings at boot.

I am also running a daily build clean install of Ubuntu 17.10 Artful Aardvark, which I think may have fixed some issues I was having with an upgrade to Zesty (Ubuntu 17.04) but you may be fine installing Zesty.

As it stands, the intel internal GPU is automatically detected, and the nvidia gpu is just never used.

(This is probably also using the internal apple_gmux driver functionality to see what is available when linux starts, so that maybe helps too.)

Hello there !

I'm having the exact same issue here trying to revive a MacBookPro 6,2 : ./gpu-switch: line 44: printf: write error: Invalid argument

I'm intending to use OS X 10.11.6, so the fix for Ubuntu will obviously not work.

Thanks for your work and thanks in advance for your kind help.

arpan-ghosh commented 7 years ago

I also have the same issue as above.

Invalid argument [Warning - gpu-power-prefs-fac4ce28d-b62f-4c99-9cc3-6815685e30f9 is incomplete

Any way to force write this, even overriding in vim doesn't work. Thanks.

pipolo commented 7 years ago

Hello !

@arpan-ghosh : your error msg ends with an 'incomplete' statement. It's easy to miss an option or suffer errors due to character encoding when copy/pasting commands (back quotes and such...). If you're sure about your command syntax and still faces error, I went around the problem using the method described here : boot to single user mode (Command + S) then type sudo nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00

Good luck !
