[SOLVED] Nvidia GeForce 920M not working with driver nvidia-470xx-dkms

Nvidia GeForce 920M not working

Hi all, intermediate user here. I have an Asus F555L with a Nvidia GeForce 920M as video card. Since I want to play some games with it, I have tried installing the video card drivers. I followed the instructions described on the wiki for Hardware video acceleration and for NVIDIA, installing the driver nvidia-470xx-dkms (AUR), but it seems my card is not working. In fact, when I try reproducing a video my CPU usage jumps relatively high (from 2% to 25%). and playing on Steam is buggy.

Then, I tried installing the 430 driver (on another group suggestion), but I cannot manage to compile it, due to, apparently, an API incompatibility (an illegal integer to pointer cast).

So, I resolved to the 470 driver.
How can I make sure the card is working/not working? And if it is not, am I missing something? I post here some outputs in case they are useful. Thanks in advance.

Re: [SOLVED] Nvidia GeForce 920M not working with driver nvidia-470xx-dkms

It's an Optimus card, regardless of the driver version you'll you need to configure it in some way to make generic use of it, details of which you'll find in https://wiki.archlinux.org/title/NVIDIA_Optimus

Re: [SOLVED] Nvidia GeForce 920M not working with driver nvidia-470xx-dkms

Thank you V1del, I'm going to try it. When I got the result I'm going to mark the topic as solved if needed.

As a side note, wandering through the wiki I didn't find any clue that my device could be an Optimus card. I don't know if it is my fault, and I needed to search better, or if it's a missing info.

Re: [SOLVED] Nvidia GeForce 920M not working with driver nvidia-470xx-dkms

It's the very first sentence of the nvidia article that should guide you to the Optimus wiki for laptops with hybrid graphics. General system level tipoffs is that you basically never get "pure" nvidia laptops that aren't a Quadro variant (... from the kepler time period) and the fact that the lspci output lists the card as a 3D controller, which always means you don't have any screens attached and you need to do some form of bending it over the intel framebuffer

Re: [SOLVED] Nvidia GeForce 920M not working with driver nvidia-470xx-dkms

The lack of general information about hybrid graphics / prime / optimus may be due to the very common misconception it's tied to a certain formfactor (laptops) .


Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
Did you use the guided installer ? If yes, I can't help you.

Re: [SOLVED] Nvidia GeForce 920M not working with driver nvidia-470xx-dkms

And we do have a laptop case here, I'm not aware of any desktop implementation that by default enables something remotely similar. All MBs I've seen so far will disable any integrated GPU by default with a distinct device present. You could enable it, but the ramifications will still be quite distinct compared to a "true" Optimus system. I don't think this is a very problematic misconception as it's almost non-existent in normal desktop usecases. Even if you had the integrated GPU enabled, unless your plug your monitors into your MB outs instead of your graphics card, the effect will not really be noticeable during normal usage.

You're right, I apologize. I think my misunderstanding arose from the fact that I didn't get the concept of a Intel GPU.

Anyway, since I am using Wayland, I'm trying to follow the instructions, but they seem to me they assume usage of X. I am trying to figure that out by myself, but if you have any advice about how to tweak the X config files for Wayland, I'd appreciate that.

This isn't really that well defined/not yet really working well in a wayland context,as far as I know. Xwayland windows should work still and I think nvidia-prime with the prime-run command should work reasonably well. But I don't have any definitve answer for that.

Re: [SOLVED] Nvidia GeForce 920M not working with driver nvidia-470xx-dkms

Ok, I stll have some problem, but I wanted to leave an update to let you know I am working on it.
It seems now the card got recognized. I installed the nvidia-470xx-dkms driver, and tried to revert all other changes I made before. For now, I only installed mesa, but I want to try if Intel hardware acceleration can coexist. Installing nvidia-settings, I can see the utilization of the GPU, so I think all is good. I installed xorg-xwayland, I didn't configure anything, and it seems that the system is nevertheless working.

However, there is a still annoying problem. I installed Steam, and I was presented with this choice:

:: There are 4 providers available for lib32-vulkan-driver:
:: Repository multilib
   1) lib32-amdvlk  2) lib32-nvidia-utils  3) lib32-vulkan-intel  4) lib32-vulkan-radeon

I choose to install the lib32-nvidia-utils (I thought that was necessary to interface with the core NVIDIA driver). When I launch Steam, all is good. I then configured the launch parameter (as described in the PRIME wiki page) like this:

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia %command%

but when I launch a game, the game windows is black. Hovering with the cursor the buttons seem to be there: in fact, I can click on where I know there is the "start" button, and the game starts normally (I can see the windows, and the performance boost is visible). Maybe the problem is in the lib32-nvidia-utils, which is the newest version, incompatible with my 470xx driver? Or maybe do I need, as optional dependency, the lib32-opencl-nvidia package (which will still pose the same question)? Or the problem may be in PRIME? So, what remains is:

  • Try to see if Intel acceleration is also possible

  • Did I do good in choosing the lib32-nvidia-utils?

  • Do I need the lib32-opencl-nvidia package? Will it conflict?

  • May PRIME be the problem?

Re: [SOLVED] Nvidia GeForce 920M not working with driver nvidia-470xx-dkms

Yes you'll definitely have a conflict here, you need to use: https://aur.archlinux.org/packages/lib3 … 0xx-utils/ matching your nvidia-470xx-utils version. You don't necessarily need the opencl package if you don't do any OpenCL based computing (mostly relevant for graphics/photo editing programs). But again, you always need to have the matching sets of packages, see this aurweb search for reference: https://aur.archlinux.org/packages/?O=0 … Search=Los always install the 470xx versions of whatever you think you need

Re: [SOLVED] Nvidia GeForce 920M not working with driver nvidia-470xx-dkms

Hi, now it works, thank you! I tried other games and they work, while the first one I tried still doesn't, so I suppose it's a matter of the game, not of the system. Now it seem I am able to at least access to the GPU and use it, so I would consider my issue solved. Thanks V1del.

For future fellows, I leave here the track of all the major steps I did, as a reference if anyone would need the same solution.

  • Installed the Nvidia driver for my card. Since I am using a GeForce 920M, I saw from the site I needed the nvidia-470xx-dkms and nvidia-470xx-utils (dependency of the dkms) driver, which I installed from AUR.

  • I also followed the wiki instruction on how to enable the DRM kernel mode setting. Early initialization seemed not be necessary.

  • I also installed the nvidia-470xx-settings, to monitor the GPU utilization.

  • I installed xwayland. No config seem to be needed.

  • I can now launch general applcations using prime-run, which correspond to

    __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia command
  • Since I wanted to install Steam, I installed also the lib32-nvidia-470xx-utils (always from AUR).

  • Along with the base AUR packages with which they were shipped, I also installed the opencl-nvidia-470xx and lib32-opencl-nvidia-470xx, even though they were optional.

  • I installed Steam.

  • I changed the launch option of the game I want to play with

    prime-run %command%
