Can't start onagre on sway/wayland

Describe the bug
The application doesn't start:

$ RUST_BACKTRACE=1 onagre

Config
n.a.

To Reproduce

• I use void linux, elogind and SwayFX on a mid 2014 macbook pro (intel integrated graphics).
• Install onagre from nixpkgs (I use the 23.05 stable channel, and I use nix because my distribution, void linux, doesn't provide onagre yet).
• Run onagre.

Expected behavior
Onagre starts.

Window manager (please complete the following information):

• Window manager: swayfx v0.3.2

I have no idea why your DE is trying to launch onagre with X11 backend.
There are a few things you could do to solve this.

1. Try to force vulkan backend (assuming you have vulkan installed on your system): WGPU_BACKEND=vulkan onagre, I am not sure but that might be related
2. Try with the latest onagre version (cargo install --git https://github.com/oknozor/onagre, you would need rust installed to do that.
3. Since your DE is trying to use X11 backend install xorg-xwayland

Let me know if any of the above works for you.

I am waiting for pop-os maintainers to publish a library so I can finally make a stable release of onagre, when that's done there will hopefully be some official package for common linux distros.

[usagi-flow]

Thank you for the suggestions @oknozor . No success so far, unfortunately:

• WGPU_BACKEND=vulkan onagre didn't work, it gives the same result.
• I tried to build from source but failed; pkg-config complained that it couldn't find fontconfig, even though fontconfig is installed. Weird...
• I actually do have xwayland and occasionally start electron apps with it, although I try to avoid it.

Hey @usagi-flow I recently made some updates and I'd like to confirm this is fixed before releasing v1. Would you mind trying to reinstall (cargo install --git https://github.com/onagre-launcher/onagre) and make a report here ?

Hi, I am currently having this issue with onagre on Hyprland, here is my trace. I use NixOS, and can reproduce this both by installing from nixpkgs and with cargo install --git https://github.com/onagre-launcher/onagre.

I also don't understand why it is unable to use Wayland

[oknozor]

Can you paste the output of RUST_BACKTRACE=1 WINIT_UNIX_BACKEND=wayland WGPU_BACKEND=vulkan onagre here ?

Here it is:

@JnsJensen are you sure vulkan is correctly installed on your system ? I don't know the specifics for NixOS.

[jens-hj]

I am quite certain, however, I am also new to Nix. I have the following in my configuration.nix, vulkan-tools, should be the package I would need. However, I get the same error with and without that package.

environment.systemPackages = with pkgs; [
    vulkan-tools
	...
    libqalculate
    hyprpaper
    hyprland
  ];

Is there a way for me to 'check' that it is correctly installed? I don't have any other issues or programs exited with anything similar.

[oknozor]

Seems related to rust-windowing/winit#3244.

[jens-hj]

Okay so, I had incorrectly assumed that nixos-rebuild switch would rebuild with the newest versions of the packages, but I understand now that I have to nix-channel --upgrade first to follow the newest updated channel. So after I did that onagre runs fine when started from the command line.

Now I am however, unable to start it with my keybinding from Hyprland, which I have set in hyprland.conf

$mainMod = SUPER
$menu = /home/<user>/.cargo/bin/onagre
bind = $mainMod, R, exec, $menu

[jens-hj]

This led me to attempt installing onagre through nixpkgs, which with RUST_BACKTRACE=1 WINIT_UNIX_BACKEND=wayland WGPU_BACKEND=vulkan onagre results in

And after removing the package again, the cargo installation goes back to same not-working state as before. I am probably doing something wrong with nix, but I am perplexed

[oknozor]

You should not try to install Onagre from official repositories, it's not released yet and the current upstream is way ahead of the packaged version.
That said it's pretty clear that you are missing some wayland dependencies. This is a bit weird since you are running on Hyprland, which would not work without wayland.
You probably want to ask for help on the iced discord server.
