Nvidia again

If you remove the Nvidia are you going to reboot first to see that it loads the nouveau and is working?

Edit: That’s what i would do first.

I don’t own any hybrid graphics setup with Nvidia. But, i can tell you on two systems one with GTX 1060 and another with GTX 1650 both have not had any issues since i added all the additional enhancements from the wiki.

Alright, back to scratch :

[onyx@onyx-rogstrixg531gt ~]$ inxi -G
Graphics:  Device-1: Intel CoffeeLake-H GT2 [UHD Graphics 630] driver: i915 v: kernel 
           Device-2: NVIDIA TU117M [GeForce GTX 1650 Mobile / Max-Q] driver: nouveau v: kernel 
           Display: x11 server: X.org 1.20.13 driver: loaded: intel,modesetting unloaded: fbdev,vesa 
           resolution: <missing: xdpyinfo> 
           OpenGL: renderer: Mesa Intel UHD Graphics 630 (CFL GT2) v: 4.6 Mesa 21.2.1 

Now, which Wiki should I be following?
This one? https://discovery.endeavouros.com/nvidia/optimus-manager-for-nvidia/2021/03/

Well, eventually I got it working;

[onyx@onyx-rogstrixg531gt ~]$ inxi -G
Graphics:  Device-1: Intel CoffeeLake-H GT2 [UHD Graphics 630] driver: i915 v: kernel 
           Device-2: NVIDIA TU117M [GeForce GTX 1650 Mobile / Max-Q] driver: nvidia v: 470.63.01 
           Display: x11 server: X.org 1.20.13 driver: loaded: modesetting,nvidia resolution: <missing: xdpyinfo> 
           OpenGL: renderer: Mesa Intel UHD Graphics 630 (CFL GT2) v: 4.6 Mesa 21.2.1 

with combination of https://discovery.endeavouros.com/articles/how-to-enable-nvidia-optimus/2019/11/
and https://discovery.endeavouros.com/nvidia/optimus-manager-for-nvidia/2021/03/
and replacing acpi_call_dkms with acpi_call,
then sudo nano /usr/lib/modprobe.d/optimus-manager.conf
and putting a hash infront of the nvidia entries. (IDK if that is supposed to be right, and I hadn’t had to do that before, but it seems to be fine now!!)
I am on the LTS kernel, I entered on Intel GPU, optimus manager would run now, and I was able to use it to swap to Hybrid.
I will push the testing further and let you know of any more grief.

So, with Optimus Manager configured to start with Intel, IF I choose the regular kernel at GRUB instead of the LTS, then when it hits SDDM it goes full lock, and I have to power off.

And after loading the Zen kernel through AKM, I find that Zen works too. So only the regular kernel is borked. What the???
And I cannot remove the regular kernel because of dependencies from acpi_call and r8168. Oh well, whatever. Thanks for the help @ricklinux and @Zircon34 !!

You could remove them first.

Yup, but will then have to figure out how to reload the network driver without a network. At this stage I am ready to fix this laptop with some percussive maintenance.

You need r8168 for your card then, alright. I didn’t think of that, sorry :blush:

What is the deal with using acpi_call? Why do you need that? Also what is the issue with the current kernel?

Edit: This is the one i tend to look at for optimus-manager

If you look at the bottom of that Wiki page it says something about being wary of acpi_call. IDK why we need to be wary of it, but in digging into the system and trying to find out why it was failing, I noticed that acpi_call was an optional depend in the pkgbuild. I also noticed that the dkms had been installed. And that it was used for the switching.
As for why the normal kernel hangs? No idea!

Does it not work without it?


I’ll experiment with the switching methods to see.
Other options are None, Nouveau, BBswitch, Custom.

@ricklinux so after changing that option to bbswitch and rebooting, the system would not load on any kernel.
Therefore BBswitch doesn’t work on Asus G531GT.
I had to follow https://github.com/Askannz/optimus-manager/wiki/FAQ,-common-issues,-troubleshooting
and use kernel parameter of systemd.unit=multi-user.target in order to boot to CLI, and get into

sudo nano /etc/optimus-manager/optimus-manager.conf

so I could change last line to switching=acpi_call
Save, reboot, back in business.

The docs here https://github.com/Askannz/optimus-manager/wiki/A-guide--to-power-management-options are vague about the other choices, so I’ll just leave it to be acpi_call until I have more time to play.

Ive just not known if anyone use the acpi_call? It’s not something i’ve even looked at. I think bumblebee is outdated and optimus manager is what i have always told others to use.
