Nvidia GLX loading issues Quadro 4000

Hi.

Lost the day trying to repair my nvidia setup with DKMS.

The problem is that GLX is no longer working:

$ glxinfo
name of display: :0
Error: couldn't find RGB GLX visual or fbconfig

hardware:

$ nvidia-xconfig --query-gpu-info
Number of GPUs: 1

GPU #0:
  Name      : Quadro 4000
  UUID      : GPU-b18c8790-1fe8-3838-9901-17a30505596e
  PCI BusID : PCI:6:0:0

  Number of Display Devices: 1

  Display Device 0 (TV-3):
      EDID Name             : DELL U2414H
      Minimum HorizSync     : 30.000 kHz

      Preferred VertRefresh : 60 Hz
      Physical Width        : 530 mm

xorg.conf

Section "Files"
    ModulePath "/usr/lib/nvidia/xorg"
    ModulePath "/usr/lib/xorg/modules"

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"

Notice that I had to add the ModulePath lines, beacuse since today, the ones from "/usr/share/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf" stoped doing anything. Without ModulePath defined in xorg.conf, I got: (http://sprunge.us/dAeC1C)

[  2811.512] (EE) NVIDIA(0):     you continue to encounter problems, Please try
[  2811.512] (EE) NVIDIA(0):     reinstalling the NVIDIA driver.

The ModulePath doesn't contain "/usr/lib/nvidia/xorg" and wrong GLX Extenssion get loaded.
So I can either get llvmpipe GLX (without the nvidia glx extenssion), or no GLX at all (when Nvidia's glx is loaded).

Any lead appreciated, I'm deseperate.
Thanks.

Edit:
Ok, thank you ducky, I found a solution two minute after posting:
Removing  the `Load "modesetting"` from the config cleared the `(EE) modeset(G0): glamor initialization failed` and GLX started working again.
KMS never worked on that setup (old Dell server hardware that doesn't initialize the GPU at boot), even with Nvidia modules in the initcpio and the right kernel command line. Maybe this is related?

Still no idea why the ModulePath update with OutputClass doesn't work.

Please ensure to have read:

This doesn't relate to the 390xx package, so if there're further problems w/ your optimus setup, please open a new thread on teh topic.

I don't have an optimus setup. The quadro GPU is the only video output on that refurbished Westmere Dell server.
And yes, I've read the section related to KMS. Using nvidia-drm.modeset=1 and packing all the modules in the initcpio never worked for me. I blame the Dell BIOS which doesn't initialize the GPU during boot, only Xorg does (no fb console displayed).

I'll try to troubleshoot the ModulePath issue. I still don't understand why it is needed now while it worked before.
I mean, an update changed on my system causing Xorg to no longer start with my previously working config. Knowing why could potentially help other users facing the same issue.

Optimus or not, that's a more complicated setup and modesetting and nvidia both try to take control over the same GPU.
The ModulePath is extended in /usr/share/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf but you don't meet the nvidia-drm match requirement (and the kernel parameter is missing in the posted X11 logs)
Please post the output of "lspci", "lsinitcpio /boot/initramfs-linux.img| grep nvidia" and a complete system journal (sudo journalctl -b)

I'll ask a mod to split this subthread off.
