Request for Help: Xorg "No screens found" Issue on Arch Linux with NVIDIA and Intel GPUs

[Falsify7342 at proton.me]

Dear Xorg Team,

I am reaching out to seek help with a persistent issue I am facing with Xorg on my Arch Linux system. I have been troubleshooting for days but have not been able to resolve the problem. I am running Arch Linux with the Hardened Kernel (6.12.6-hardened1-2-hardened), and my system has both Intel (iGPU) and NVIDIA (dGPU) GPUs. Here are the details:

System Information

Kernel: 6.12.6-hardened1-2-hardened

Intel GPU: Intel Raptor Lake-P (UHD Graphics), BusID PCI:0:2:0

NVIDIA GPU: NVIDIA RTX 2050, BusID PCI:1:0:0

Xorg version: 1.21.1.15

NVIDIA driver: nvidia-dkms 565.77-2

Intel driver: modesetting

Problem Description

The issue arises when I try to start Xorg. It consistently fails with the error:

Fatal server error:
(EE) no screens found(EE)

I’ve checked the /var/log/Xorg.0.log file, and the relevant part of the log shows:

(EE) NVIDIA: Failed to initialize the NVIDIA GPU at PCI:1:0:0.
(EE) No devices detected.
(EE) No screens found.

Steps I Have Taken

1. Xorg Configuration File
I created a configuration file at /etc/X11/xorg.conf.d/10-prime.conf to set up PRIME for the hybrid GPU system. Here is the configuration:


Section "ServerLayout"
    Identifier "layout"
    Screen 0 "nvidia"
    Inactive "intel"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1:0:0"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
EndSection

Section "Device"
    Identifier "intel"
    Driver "modesetting"
    BusID "PCI:0:2:0"
EndSection

Section "Screen"
    Identifier "intel"
    Device "intel"
EndSection

2. Verified Hardware and Drivers


lspci confirms that both GPUs are present.

nvidia-smi recognizes the NVIDIA GPU and shows it is functional.

The lsmod command confirms that both the nvidia and i915 modules are loaded.

3. Checked Variables and PRIME


I attempted to use prime-run glxinfo | grep "OpenGL renderer", but it fails with the error: unable to open display.


4. Logs
I have attached the complete /var/log/Xorg.0.log for reference.
