Not listed is the 4070ti my computer is using. Nvidia X-server is installed, and is correctly reading the GPU, not sure what happened.

what does "nvidia x-server is installed" mean ? how did you install/setup the nvidia drivers ? did you follow the official guide ? we need actual info to help you

s4dmoss · 2024-10-11 21:39:36

yes, i had followed the official guide. I had picked the option to install it using archinstall initially, but it didn't seem to work, so i went through the official guide. everything seems to be installed, but it just isn't using the gpu to output anything?

jonno2002 · 2024-10-11 21:54:43

sorry should have been more specific, provide actual details of everything you did, packages installed, configs changed, etc
also if you generated a static xorg config (/etc/X11/xorg.conf) please delete it

These are the file's i've changed.

as for packages, should i post pacman -Q?

not that anything xorg related should matter cause ive just noticed your using wayland, also how do you know the nvidia card isnt being used ?
whats the output of:

nvidia-smi && glxinfo -B && vulkaninfo --summary

'mesa-utils' package is required for glxinfo and 'vulkan-tools' for vulkaninfo

It's primarily just because games aren't performing as well as I want them to, one example is that Minecraft only shows the Radeon Graphics being used.
Also I deleted the file you asked.

indeed opengl seems to be using the amd gpu and vulkan and kwin/xorg are using the nvidia gpu.
ive got no more time today but im sure someone else will jump in and sort it for you

rek · 2024-10-12 04:38:13

i have the same issue, it just dawned on me that opengl is running on my cpu's integrated graphics, but it could or perhaps even should be running on my GPU. I've heard talk about nvidia prime or optimus to manage that kind of stuff, is that correct?

seth · 2024-10-12 15:03:43

What you see is (most likely) the default, normal and perfectly expected.
https://wiki.archlinux.org/title/PRIME# … figuration
tl;Dr

prime-run superturboturkeypuncher³  # the nvidia-prime package provide that script that just sets some environment variables

You might also have to explicitly select the vulkan provider for relevant clients, https://wiki.archlinux.org/title/Vulkan … initialize

s4dmoss · 2024-10-12 18:29:25

yeah using prime-run seems to do it, running minecraft-launcher with it seems to force the gpu to be used.

can i set it to force nvidia usage a

Wrap it in a script, in doubt shadowing the binary (which might just be a script anyway) in /usr/local/bin

s4dmoss · 2024-10-12 18:35:49

sorry i mean for ALL OpenGL apps?

jonno2002 · 2024-10-12 21:35:18

if you dont want to use the integrated gpu you could just blacklist it and that would greatly simplify things

seth · 2024-10-13 08:00:35

Or, if you can, disable it in the firmware (BIOS/UEFI) to save more battery (or don't burn down the planet - whatever is more important to you)

s4dmoss · 2024-10-13 10:11:32

yeah disabling it in bios fixed pretty much everything.
thank you guys!

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
