Arch use LLVMPIPE instead of nvidia driver on RTX 5070

I mainly suspect 2 problems:
1. nvidia-smi and others like nvtop report the card correctly but no process using it

kind of like this topic: https://bbs.archlinux.org/viewtopic.php?id=302266

> ls /sys/module/nvidia_drm
ls: cannot access '/sys/module/nvidia_drm': No such file or directory

but

> ls /sys/module | grep nvidia
nvidia
nvidia_uvm

and when I do

sudo modprobe nvidia_drm -vv

it will panic with

---

version info:
it happened both on kernel `6.13.8` and `6.14.0`.
it happened both on `nvidia-open-dkms`, `nvidia-open-dkms-git`, `nvidia-open-beta`.

config:
I disabled my bundled AMD gpu by `install amdgpu /usr/bin/false` in `/etc/modprobe.d/blacklist.conf`
disabled nouveau by configing `/etc/modprobe.d/nvidia.conf` with

blacklist nouveau
options nvidia_drm modeset=1 fbdev=1

/etc/mkinitcpio.conf:

MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)

...
HOOKS=(base udev autodetect microcode modconf keyboard keymap block filesystems fsck plymouth)

I'm connected the monitor with the HDMI port on the graph card instead of the HDMI port on the motherboard

Please post your complete system journal for the boot:

can be sth about this?

I disabled my bundled AMD gpu by `install amdgpu /usr/bin/false` in `/etc/modprobe.d/blacklist.conf`

That's not how this works.
https://wiki.hyprland.org/Configuring/M … gpu-to-use

But amdgpu isn't loaded, the the result is 

Apr 03 11:01:45 NAMED uwsm_hyprland.desktop[4631]: [LOG] [AQ] drm: Enumerated device /sys/devices/pci0000:00/0000:00:01.1/0000:01:00.0/simple-framebuffer.0/drm/card0

Apr 03 11:01:47 NAMED uwsm_hyprland.desktop[4631]: [LOG] DRM driver information: simpledrm v1.0.0 from 0 description DRM driver for simple-framebuffer platform devices

nvidia_uvm is cuda-stuff, idk whether it's supported w/ nvidia-open, but it will not be the cause for the software rasterizer.
Adding "nvidia_drm.modeset=1" to the https://wiki.archlinux.org/title/Kernel_parameters (and *ONLY* there) will block the simplydumb device, but I'd not rely on hyprland picking up the nvidia GPU automagically by that (you may try, though - however it seems you're using an output that's connected to the AMD GPU?)

ok I remove the blacklist of my AMD gpu and change the config in `~/.config/hypr/hyprland.conf`

# NV
env = LIBVA_DRIVER_NAME,nvidia
env = GBM_BACKEND,nvidia-drm
env = __GLX_VENDOR_LIBRARY_NAME,nvidia
env = AQ_DRM_DEVICES,/dev/dri/card0:/dev/dri/card1

but it is still using software I assume
