[SOLVED] vulkaninfo, nvidia_debugdump look fine but applications hang

This is a mostly fresh install I have not yet finished. I have reached the step to install graphics drivers and cannot complete it, but e.g. sound is probably not yet done, nor are later steps of the installation guide.

I have tried to follow the manual at pages NVIDIA, Wayland, Vulkan, etc. with issues. (E.g. there is no way to install either wayland or xorg-server : they are both dependencies of nvidia.)

Nevertheless, after a restart, I get good looking output from vulkaninfo (even directly from TTY!?) and from nvidia_debugdump -l -z -v .

When I try to start applications, however, I get one of two behaviours:

• starting weston

  • starting warzone2100 --debug=3d crashes with this output

  • starting vkcube_wayland --validate crashes with this output

• starting prime_run weston or starting either application in Weston via prime_run

  • starting warzone2100 --debug=3d hangs indefinitely after this output, ignoring TERM signal

  • starting vkcube_wayland --validate hangs indefinitely after this output, ignoring TERM signal

Output of nvidia_debugdump -l -z -v
Output of vulkaninfo

These are the currently installed packages, the vast majority of which have been automatically pulled as dependencies, the rest came from following the manual.

Unfortunately, without actionable error messages I find myself unable to make progress on this issue. Any hints on how to proceed? Do I even need Wayland, Weston, etc. if vulkaninfo looks good to go?
Most topics on this behaviour seem to be about an issue in older NVidia drivers or claim that vulkaninfo should not output sensible data before "it just works". The rest deals with additional/alternative software I do not use, e.g. GDM.

Yup, archlinux devs often enable everything possible + the kitchen sink .

Even if you build nvidia without X support, you'd still get X installed because nvidia depends on glvnd which depends on mesa and archlinux mesa package requires both X and wayland .
TL;DR : if you want to run a wayland-exclusive distro, look elsewhere.

prime-run is only useful / needed on systems with 2 videocards (usually intel + nvidia or amd + nvidia) .

Please post full output of lspci -knn as regular user.
Install vulkan-mesa-layers, then run vulkaninfo --summary and post that also.

Oh and please use a pastebin service instead of dropbox .

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Alright...

Output of lspci -knn
Output of vulkaninfo --summary
... Huh. Looks good, does it not? If any of that is supposed to signal issues, I sure don't recognise it.

Note that I have not yet set up a regular user, so this is all as root. In case I have to redo the installation I'd like to do "administrative" stuff like users, partitions, etc. last (or at least after having running drivers for everything).

Re: [SOLVED] vulkaninfo, nvidia_debugdump look fine but applications hang

This actually is a hybrid system.
https://archlinux.org/packages/extra/x8 … kan-intel/
https://wiki.archlinux.org/title/Vulkan … _installed?

If you want to use the nvidia GPU
1. https://wiki.archlinux.org/title/PRIME# … figuration
2.

cat /proc/cmdline

If you "forgot" to add "nvidia-drm.modeset=1", revisit the wiki and fix that.

Re: [SOLVED] vulkaninfo, nvidia_debugdump look fine but applications hang

Late follow-up: This February I completely reinstalled everything, starting with a fresh 2025 Arch USB image and then following the same steps from the Wiki as I had in 2023.

- This time I do not have this problem. "It just works."(TM)
