Wayland + GNome with nvidia-470xx drivers segfaults

Wayland test
============

Following seth's recommendation:
Unlike 390xx, the 470xx drivers support KMS and GBM - what exactly doesn't work? Do you have an open thread about that (please don't hijack this one)

This is my second attempt to get GNome working with Wayland on my computer with this graphics card:

VGA compatible controller [0300]: NVIDIA Corporation GK104 [GeForce GTX 760] [10de:1187] (rev a1)

and with this driver:

nvidia-470xx-dkms 470.256.02-8.00

I activate modeset in Grub

sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet nvidia-drm.modeset=1 nvidia_drm.fbdev=1"
^X # Save and exit
sudo grub-mkconfig -o /boot/grub/grub.cfg

I modify mkinitcpio to add the nvidia modules 

sudo nano /etc/mkinitcpio.conf 
MODULES=(btrfs nvidia nvidia_modeset nvidia_uvm nvidia_drm) 
# I remove kms because nvidia already enables kms with its modules 
HOOKS=(base udev autodetect microcode modconf keyboard keymap consolefont block filesystems fsck grub-btrfs-overlayfs) 
^X # Save and exit 
sudo mkinitcpio -P

I edit /etc/environment

 # 
# This file is parsed by pam_env module 
# 
# Syntax: simple "KEY=VAL" pairs on separate lines 
# 
EDITOR=nano 

# Wayland test
GBM_BACKEND=nvidia-drm
__GLX_VENDOR_LIBRARY_NAME=nvidia

I edit /usr/lib/udev/rules.d/61-gdm.rules

# I comment out the line where Wayland is disabled
LABEL="gdm_disable_wayland"
# RUN+="/usr/lib/gdm-runtime-config set daemon WaylandEnable false"

I reboot, and now GDM gives me the option to start GNOME or GNOME Xorg. I choose GNOME and it boots with Wayland.

I've tried a few apps and they work fine:
Firefox, Blender, Geany, Intellij IDEA, ...

Issues:
Curiously, GNome applications mostly fail

I'm trying to run kgx from a terminal. Journalctl output:

I don't know if the problem is a missing library or something else.
Any solutions or suggestions are welcome.

Re: Wayland + GNome with nvidia-470xx drivers segfaults

My suggestion: put 

GSK_RENDERER=gl

into /etc/environment

I am the unhappy owner of a GTX 660 (same driver).

Re: Wayland + GNome with nvidia-470xx drivers segfaults

@koneko Thank you for your suggestion, but gl renderer is now deprecated and ngl is the new default. When I use that renderer in xorg the thumbnails previews in nautilus doesn't work and I must use the vulkan renderer. Although the renderer is not the problem with wayland. I don't know who produces the libEGL warning showed before.

Re: Wayland + GNome with nvidia-470xx drivers segfaults

knoeko's thread is https://bbs.archlinux.org/viewtopic.php?id=308466 - see also there because of the vulkan support and try gl or ngl nevertheless (though afaiu ngl became gl and gl was dropped? I'd have to look that up to be sure)

You can skip "nvidia_drm.fbdev=1" - that's not supported on that driver anyway.

Wrt "GBM_BACKEND=nvidia-drm", see https://wiki.archlinux.org/title/Wayland#Requirements - seems 470xx doesn't support GBM after all, you're looking to run on eglstreams and not on the simpledrm device.
Try to blacklist the latter ("module_blacklist=simpledrm") and check "glxinfo -B"

Re: Wayland + GNome with nvidia-470xx drivers segfaults

@koneko Thank you for your suggestion, but gl renderer is now deprecated and ngl is the new default.

Full-circle...the NGL renderer (naming only) is now deprecated and is simply referred to as GL.

You're correct that the (old) GL renderer itself is long gone (removed from codebase).

For a few release cycles (4.14..4.20) you could use GSK_RENDERER=gl and be warned that NGL was being used instead.

Going forward, using GSK_RENDERER=ngl will give a warning instead that the GL renderer will be used as NGL name has been retired.

• https://gitlab.gnome.org/GNOME/gtk/-/me … uests/8440

I would not expect anyone to keep up with this.

All that aside, try the GL renderer.


Oh, and these errors should be innocuous:

pci id for fd 32: 10de:1187, driver (null)
pci id for fd 33: 10de:1187, driver (null)

Introduced in mesa 25.2.2.

• https://gitlab.freedesktop.org/mesa/mesa/-/issues/13684

I still see the same errors in eglinfo output, but they're no longer emitted by GTK4 apps using Vulkan backend (fixed with Mesa 25.2.3).

The bug got closed by the OP, and I simply don't care enough to pursue it further. It's just a bit of harmless noise. Unlike your segfault.

Re: Wayland + GNome with nvidia-470xx drivers segfaults

Let's move on...
Following @seth's recommendation, I removed the 

nvidia_drm.fbdev=1

option from grub and removed

GBM_BACKEND=nvidia-drm
__GLX_VENDOR_LIBRARY_NAME=nvidia

from /etc/environment. In that file, I added the line

GSK_RENDERER=gl

Although I think it's unnecessary because that RENDERER is used by default.
I also added

nvidia.NVreg_PreserveVideoMemoryAllocations=1

to grub because I read that without this option and without having modeset enabled, the 61-gdm.rules disables Wayland.
The reality is that it still disables it, and I have to comment out the line

# RUN+="/usr/lib/gdm-runtime-config set daemon WaylandEnable false"

so that GDM gives me the option to start Wayland.

After all this, I restart the computer and log in to Wayland.
The applications that weren't starting now work: kgx, gnome-control-center, ...

But...
The nvidia-settings application won't start:

$ nvidia-settings

with xorg it reaches 60fps
with Wayland it doesn't go over 32 :-(

See:

Native Wayland nvidia-settings support didn't come around until driver 570.86.16 release.

Keep in mind your card is on the very cusp of being able to Wayland at all, and without GBM.

Gnome is unlikely a tenable long-term environment with your hardware.

EDIT:

If you just want to buy another ~6 months, I suggest rebuilding the required session components with X11 enabled.

gdm, session, shell, and mutter all compile quite quickly.

I maintained the inverse (pure native Wayland sans Xwayland / X11 Gnome for a couple years.

It should not be possible that modern FF falls back to Xwayland, but do check about:support to be sure.

You're still running on llvmpipe, so likely simpledrm - add  "module_blacklist=simpledrm" and in doubt then please post your complete system journal for the boot:

Re: Wayland + GNome with nvidia-470xx drivers segfaults

Than you @tekstryder
I know that my hardware is quite old (me too :-) but it works and suit my needs. I'm resisting buying a new graphics card.
The nvidia-settings problem is not a problem indeed.

My firefox is using wayland as window protocol so I can't understand why it has this low fps performance.

chromium doesn't start in wayland

Re: Wayland + GNome with nvidia-470xx drivers segfaults

Ensure the simpledrm device is blocked per #8.

You can surely rock that GPU for many years to come!

Future kernel support and Wayland may be a rocky road tho wink

Re: Wayland + GNome with nvidia-470xx drivers segfaults

Depends on whether and how well nouveau or nova support those chips…
The HW is certainly beyond capable of running any DE or wayland but the CSS driver is gonna be increasingly a problem (I suspect gnome being gnome will eventually drop eglstreams as well)

Nova requires GSP, so non-starter.

Nouveau is certainly viable just not performative. It's even got Vulkan / NVK support now, at least for my old Pacal chip.

Re: Wayland + GNome with nvidia-470xx drivers segfaults

I'm not sure if I blacklisted simpledrm correctly. Just modified grub

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet module_blacklist=simpledrm nvidia-drm.modeset=1"

But glxinfo -B yields the same result:

Well, not entirely.
As I mentioned before, the webrenderer's performance in Firefox has dropped by half.
I use Blender with Xorg smoothly on my hardware, however, with Wayland it's extremely slow.
I don't know if I should use some 470xx driver option I'm not familiar with, or if I need to make some other adjustment to improve performance in Wayland.
Here's the information you asked for.

Re: Wayland + GNome with nvidia-470xx drivers segfaults

Well, not entirely.

"promising", we know from the glxinfo that it doesn't really succeed - and gnome-shell/mutter are not attached to the GPU.
You can skip the program tests, as long as "glxinfo" says "llvmpipe" you're running software emulation.
The question remains "why"

printenv

(most unfortunately gnome is the only wayland compositor w/ eglstreams support, so we cannot test other compositors sad )

Re: Wayland + GNome with nvidia-470xx drivers segfaults

What graphics card do you recommend :-P ?

The one you like he most, but you'll need a newer nvidia GPU w/ support for the 5xxyy drivers for GBM/wayland.

The environment doesn't look prone to drift you into software emulation.

Export all of

MUTTER_DEBUG_FORCE_EGL_STREAM=1

Re: Wayland + GNome with nvidia-470xx drivers segfaults

Hi!
I've added those vars one at a time and reboot.
Adding

MUTTER_DEBUG_FORCE_EGL_STREAM=1

no changes in glxinfo nor eglinfo

Adding

__GLX_VENDOR_LIBRARY_NAME=nvidia

glxinfo shows the GPU as renderer

name of display: :0
display: :0  screen: 0
direct rendering: Yes
Memory info (GL_NVX_gpu_memory_info):

    Total available memory: 2048 MB
    Currently available dedicated video memory: 1785 MB
OpenGL vendor string: NVIDIA Corporation

OpenGL version string: 4.6.0 NVIDIA 470.256.02
OpenGL shading language version string: 4.60 NVIDIA
OpenGL context flags: (none)
OpenGL profile mask: (none)

OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 470.256.02
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20

Adding

GDK_DISABLE=vulkan

has no effect

Adding

VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json

no changes

Re: Wayland + GNome with nvidia-470xx drivers segfaults

It appears to support GBM.

Yes of course.

I'd say this is the bad part:

Adding
__EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json

eglinfo -B

eglinfo -B

Wayland platform:
eglinfo: eglInitialize failed

X11 platform:
eglinfo: eglInitialize failed

An easy "solution" would oc be to just run the system in normal prime configuration (why aren't you doing that anyway?)
Ie. run gnome on the intel chip and "prime-run superturboturkeypuncher³" for maximum FPS.

Re: Wayland + GNome with nvidia-470xx drivers segfaults

One thing I've noticed after switching to Wayland is that I've stopped experiencing the frequent graphics card freezes I had with Xorg. Especially after a reboot.
