Help turning off Radeon (discrete GPU, acpi_call)

Hello guys, I have a Pavilion Dv6 laptop, with hybrid graphics (one integrated GPU, into the Core i7, and one discrete GPU, AMD Radeon 6490M). I hardly ever play games on Linux, so I want to turn off completely the discrete graphics to save battery and stuff, and use the integrated only. Googling I found out that to turn it off  acpi_call-git is needed (from AUR), so I installed it. Loaded the module with modprobe and ran turn_off_gpu.sh, which output is:

Trying \_SB.PCI0.P0P1.VGA._OFF: failed
Trying \_SB.PCI0.P0P2.VGA._OFF: failed
Trying \_SB_.PCI0.OVGA.ATPX: failed
Trying \_SB_.PCI0.OVGA.XTPX: failed
Trying \_SB.PCI0.P0P3.PEGP._OFF: failed
Trying \_SB.PCI0.P0P2.PEGP._OFF: failed
Trying \_SB.PCI0.P0P1.PEGP._OFF: failed
Trying \_SB.PCI0.MXR0.MXM0._OFF: failed
Trying \_SB.PCI0.PEG1.GFX0._OFF: failed
Trying \_SB.PCI0.PEG0.GFX0.DOFF: failed
Trying \_SB.PCI0.PEG1.GFX0.DOFF: failed
Trying \_SB.PCI0.PEG0.PEGP._OFF: works!
Trying \_SB.PCI0.XVR0.Z01I.DGOF: failed
Trying \_SB.PCI0.PEGR.GFX0._OFF: failed
Trying \_SB.PCI0.PEG.VID._OFF: failed
Trying \_SB.PCI0.PEG0.VID._OFF: failed
Trying \_SB.PCI0.P0P2.DGPU._OFF: failed
Trying \_SB.PCI0.P0P4.DGPU.DOFF: failed
Trying \_SB.PCI0.IXVE.IGPU.DGOF: failed
Trying \_SB.PCI0.RP00.VGA._PS3: failed
Trying \_SB.PCI0.RP00.VGA.P3MO: failed
Trying \_SB.PCI0.GFX0.DSM._T_0: failed
Trying \_SB.PCI0.LPC.EC.PUBS._OFF: failed
Trying \_SB.PCI0.P0P2.NVID._OFF: failed
Trying \_SB.PCI0.P0P2.VGA.PX02: failed
Trying \_SB_.PCI0.PEGP.DGFX._OFF: failed
Trying \_SB_.PCI0.VGA.PX02: failed

So \_SB.PCI0.PEG0.PEGP._OFF works, so I started setting up stuff to turn off the gpu on boot.

I created in /etc/modules-load.d a file acpi_call.conf with inside only "acpi_call"; Then I made a script (/etc/switchoff.sh) with inside 

sudo sh -c "echo '\_SB.PCI0.PEG0.PEGP._OFF' > /proc/acpi/call"

; chmodded it a+x, created /etc/systemd/system/gpu-switchoff.service (to make the script start on boot) with inside 

[Unit]
Description=Turn off dedicated graphics

[Service]
Type=oneshot
ExecStart=/etc/switchoff.sh

[Install]
WantedBy=multi-user.target

and run sudo systemctl enable gpu-switchoff and rebooted. After reboot I ran dmesg | grep acpi_call, but:

So something clearly doesn't work. Ideas?

Maybe there's something wrong with the systemd service, output of systemctl status gpu-switchoff is:

gpu-switchoff.service - Turn off dedicated graphics
   Loaded: loaded (/etc/systemd/system/gpu-switchoff.service; enabled)
   Active:failed (Result: exit-code) since ven 2013-05-31 17:26:19 CEST; 1h 33min ago

Re: Help turning off Radeon (discrete GPU, acpi_call)

Do you want to have the ability to turn it on when you need it?
If not, blacklist radeon with "modprobe.blacklist=radeon" in your kernel boot line.

I don't quite get you, turn on what? And which effects would have blacklisting radeon (gpu not turning on at all)?

Re: Help turning off Radeon (discrete GPU, acpi_call)

Playing with this also, since i'm tuning my system to use less power.
To disable it completely you need to take three steps as per wiki:

1. Blacklist the radeon module by creating the file /etc/modprobe.d/radeon.conf containing:

blacklist radeon

2. Make sure acpi_call is loaded at boot by creating the file /etc/modules-load.d/acpi_call.conf containing:

acpi_call

3. Tell systemd to write the proper value to /proc/acpi/call by creating the file /etc/tmpfiles.d/acpi_call.conf (also see: man tmpfiles.d) and make sure it contains:

w /proc/acpi/call - - - - \_SB.PCI0.PEG0.PEGP._OFF

Reboot and it should automaticly blacklist radeon module, start acpi_call and write the correct value to it.
This can also be found in the wiki article about hybrid graphics by the way wink

So something clearly doesn't work. Ideas?

Maybe there's something wrong with the systemd service, output of systemctl status gpu-switchoff is:

gpu-switchoff.service - Turn off dedicated graphics
   Loaded: loaded (/etc/systemd/system/gpu-switchoff.service; enabled)
   Active:failed (Result: exit-code) since ven 2013-05-31 17:26:19 CEST; 1h 33min ago
  Process: 351 ExecStart=/etc/switchoff.sh(code=exited, status=203/EXEC)

Do you solve?
If not, you should follow these steps:
1) Install acpi_call-git from AUR

2) Run as root 

modprobe acpi_call

3) Download and install acpi_call_GUI_systemd (read the description for how to install): https://github.com/marcoDallas/acpi_call_GUI_systemd (or create your own systemd file)

4) Run acpi_call_GUI_systemd and only use "change deactivation code" and then "automates disabling discrete GPU every boot",
see here for a video guide: https://www.youtube.com/watch?v=h33bvoR14x8 (or create your own systemd file)

5) Load acpi_call kernel module every boot like explained here: https://wiki.archlinux.org/index.php/Ke … es#Loading

6) Blacklist radeon module like explained here: https://wiki.archlinux.org/index.php/Ke … acklisting

7) That's all!

Bye!
