Hi everyone,
This is my very first post on these forums, so I’d like to apologize in advance if I’m posting in the wrong place.
I have intel/nvidia hybrid graphics. I don’t need Nvidia, because I don’t really do anything graphics intensive. Also, I want to get rid of nouveau because it’s been causing issues with my wifi usb adaptor (completely black screen after suspend where I can’t do anything beside force power off the laptop. Not even TTY). So, I’m forced to run the “auto install proprietary driver” in the settings, but that is eating the battery really quick on my laptop. So, my question is, like the title says, is it at all possible to run only on intel’s graphics? Like disable nvidia and nouveau completely? (Note that I don’t have an option to disable nvidia on my BIOS) If so, how? I am not an advanced user by any means, but I can follow instructions, as long as they are not too complicated. Also, I don’t know what’s currently running my system, intel, nvidia or nouveau. Like I mentioned, I did “auto install proprietary driver” from the hardware configurations in the settings.

I have nvidia GeForce MX130, but I don't know why it isn't showing in the settings.
Thank you in advance

Fixed it. Hope that works now.

Thanks.
I would suggest first make sure to have only the following mhwd profiles installed:
video-linux
video-moesetting
If you dont know how click this
Here is an an example of listing, removing and installing:
mhwd -li
sudo mhwd -r pci video-nvidia
sudo mhwd -i pci video-linux
Then blacklist nouveau:
printf 'blacklist nouveau\noptions nouveau modeset=0' | sudo tee /etc/modprobe.d/blacklist-nouveau.conf
If you want to go further and make sure the card is fully powered down you can probably do so with acpi_call. To install the module for your kernel:
sudo pacman -Syu $(ls /boot | awk -F "-" '/^linux/ { print $1"-acpi_call" }')
(you may wish to restart here - especially if there were a number of updates)
Then load the module:
sudo modprobe acpi_call
And try turning off the card with the provided script:
sudo /usr/share/acpi_call/examples/turn_off_gpu.sh
A couple of questions if you don’t mind.
Will this disable nouveau and nvidia and leave only intel?
Also, this command you provided
sudo /usr/share/acpi_call/examples/turn_off_gpu.sh
Do I just run it as is, or do I replace the “examples” with something?
And which provided script are you talking about?
I’m trying to post a screenshot of my current set up, but I can’t. I have “video-hybrid-intel-nvidia-prime” on both nvidia and intell sections. Then after that, I have modsettings checked. All of that is in the “installed” section.
Here is what mhwd -li
give me
Installed PCI configs:
--------------------------------------------------------------------------------
NAME VERSION FREEDRIVER TYPE
--------------------------------------------------------------------------------
video-modesetting 2020.01.13 true PCI
video-hybrid-intel-nvidia-prime 2021.12.18 false PCI

Run as-is, that is the path. It is the script.
(note - .sh
is a common extension for scripts)
Then remove it with
sudo mhwd -r pci video-hybrid-intel-nvidia-prime
Running
sudo /usr/share/acpi_call/examples/turn_off_gpu.sh
gave me this:

Did you install and start the module ?
Twice. The second time to make sure I did. I rebooted after installing it then ran the last command.

It wont be loaded after a restart, we are just testing it.
So make sure it is loaded with modprobe.
And … oh, maybe we want to do it a little differently…
cd /
sudo ./usr/share/acpi_call/examples/turn_off_gpu.sh
Same results.
Installed it with this command
sudo pacman -Syu $(ls /boot | awk -F "-" '/^linux/ { print $1"-acpi_call" }')
did NOT reboot
then ran
sudo modprobe acpi_call
then cd /
and
sudo ./usr/share/acpi_call/examples/turn_off_gpu.sh
and I’m still getting this
sudo: ./usr/share/acpi_call/examples/turn_off_gpu.sh: command not found

Ok … now the lookyloo:
pacman -Qs acpi_call
lsmod | grep acpi_call
ls -la /usr/share/acpi_call/examples
This is what I got
[kalzi@Jaro /]$ pacman -Qs acpi_call
local/linux515-acpi_call 1.2.2-4 (linux515-extramodules)
A linux kernel module that enables calls to ACPI methods through /proc/acpi/call
[kalzi@Jaro /]$ lsmod | grep acpi_call
acpi_call 16384 0
[kalzi@Jaro /]$ ls -la /usr/share/acpi_call/examples

…hah. I gave you the wrong path.
(it was missing the kernel-module directory)
/usr/share/linux515-acpi_call/examples/turn_off_gpu.sh
Ran it without sudo
and got a bunch of “permission denied” then ran it with sudo
and got this:

Also, went into the file itself with dolphin, clicked on it to excute it, but nothing happened. Opened that directory with a terminal and ran that single .sh file, but it keeps telling me sudo: turn_off_gpu.sh: command not found
From the long output above, it looks like there is something wrong with line 41 in that file result=$(cat /proc/acpi/call)

We might try running it as root for real and making sure its bash;
su -
bash
cd /
./usr/share/linux515-acpi_call/examples/turn_off_gpu.sh
same long message. There is something wrong with line 41 of the acpi_calls
this one result=$(cat /proc/acpi/call)

Hm. Yeah. I see some other reports.
Care to try replacing the script?
Maybe back up first;
sudo mv /usr/share/linux515-acpi_call/examples/turn_off_gpu.sh /usr/share/linux515-acpi_call/examples/turn_off_gpu.sh.bak
sudo nano /usr/share/linux515-acpi_call/examples/turn_off_gpu.sh
And put in the following:

And try again
Which command should I try after doing these two
sudo mv /usr/share/linux515-acpi_call/examples/turn_off_gpu.sh /usr/share/linux515-acpi_call/examples/turn_off_gpu.sh.bak
sudo nano /usr/share/linux515-acpi_call/examples/turn_off_gpu.sh
of course, pasting the long script you provided
Sorry, I am kind of getting confused. lol
just give me the command you wanted me to try after your last comment
