Please don't post pictures of text you can curl the output into 0x0.st, eg.

dkms status | curl -F 'file=@-' 0x0.st

Done.

Pardon, I have seen your post after I have made that post with the picture.

nvidia is installed for 6.8.9-arch1-2 but currently not used

1c:00.0 VGA compatible controller: NVIDIA Corporation GP108 [GeForce GT 1030] (rev a1)
	Subsystem: ASUSTeK Computer Inc. Device 8621
	Kernel modules: nouveau

You'd have to install the linux-zen-headers and rebuild the dkms modules (or at least for that kernel)

It *was* used in the boot that generated the xorg log:

[    14.358] Current Operating System: Linux workstation 6.8.9-arch1-2 #1 SMP PREEMPT_DYNAMIC Tue, 07 May 2024 21:35:54 +0000 x86_64
[    14.358] (==) Log file: "/home/admin/.local/share/xorg/Xorg.0.log", Time: Thu May  9 17:40:44 2024
[    14.380] (II) NVIDIA Unified Driver for all Supported NVIDIA GPUs
[    14.384] (II) LoadModule: "glxserver_nvidia"

webkit *still* didn't render properly on that server?
Despite the completely different GL stack?

Sidebar: remove xf86-video-vesa.

Yes, on X11 on Linux. Linux Zen could not even start a display server.

I do not know what to answer as I am not familiar with the technicalities.

Done.

I have removed Linux Zen files in order to login again, because my network is not in order and arch-chroot could not connect to network, even though it did connect earlier.

It appears there is a problem.

Can we remove Linux Zen?

What is it and what is it needed for?

tl;dr, another kernel w/ some patches and different configs.
You don't "need" that but having it around will also not harm you.

Check the dkms log, either you're running into https://bbs.archlinux.org/viewtopic.php?id=295600 or you're just missing linux-zen-headers

Back on topic: if "glxinfo -B" and the Xorg log suggest you're running on the nvidia GL library, but webkit doesn't render as it did not on mesa/nouveau but software rendering works (the LIBGL_ALWAYS_SOFTWARE=1 trick will not work w/ the nvidia drive, you'll have to run "__GLX_VENDOR_LIBRARY_NAME=mesa browser") but otoh things did (and do) work on wayland this is probably some bug in the GLX backend that gets side-stepped by EGL on wayland.

1) I did not yet check the dkms log.
2) I have removed Linux Zen so I can make use of this system.
3) It would be helpful if both kernels (Linux and Linux Zen) would appear in GRUB.

Observations #1 and #2

$ liferea
AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer
AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer
AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer
AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer

$ GDK_DEBUG=gl-egl liferea
AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer
AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer

AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer

$ LIBGL_ALWAYS_SOFTWARE=1 liferea
AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer
AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer
AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer

Result: HTML rendering does not work.

Observations #3 and #4

$ __GLX_VENDOR_LIBRARY_NAME=mesa liferea

** (liferea:16066): WARNING **: 04:21:24.643: Disabled hardware acceleration because GTK failed to initialize GL: No available configurations for the given RGBA pixel format.

$ WEBKIT_DISABLE_DMABUF_RENDERER=1 liferea

Result: HTML rendering does work.

If

WEBKIT_DISABLE_DMABUF_RENDERER=1 liferea

works you're hitting a bug in the dmabuf renderer you probably want to file, https://bugs.webkit.org/buglist.cgi?quicksearch=dmabuf
