Hi!

I am working with a team for a Forge-powered modded server which, for various technical and logistics reasons, utilizes a custom launcher (specifically a fork of HeliosLauncher). This works well for most of our uses, but specifically our Wayland Linux users (Arch, Fedora, SteamOS, etc.) are unable to start the game due to a crash.

This is the entire game log file:

Failed to initialize graphics window with current settings.


Failure details:
We are unable to initialize the graphics system.
glfwInit failed.


If you click yes, we will try and open https://links.minecraftforge.net/early-display-errors in your default browser

 

Most users report that a crash report is never generated by the game, however, there is more information available in the launcher's console:

In doing research, I found information that Minecraft and Wayland generally don't get along without this patch and these extra JVM options for Forge, but this hasn't helped. It actually looks as though Forge is ignoring my JVM flags and starting its early window anyway.

The usual driver and systems updates have been done in all cases to no avail. This issue occurs for a dozen or so of our modpack users on different distros, but all using Wayland.

Forge: 47.2.20
Minecraft: 1.20.1

Any ideas?

Wayland isn't supported in vanilla minecraft until 1.20.2

As for anything the early loading screen does, you can edit the fml.toml to disable it. I dont think the environment variable has been functional since the loading screen rewrite.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Thanks for the info.

For the toml, I assume you're referring to earlyWindowControl?
I tried that setting and it either doesn't work too, or something else is the root cause. We also tried injecting a patched libglfw but it hasn't help either.

Unsure if there is a path forward with this still or if the only option is to just upgrade to 1.20.2+.
