No GLXFBConfigs returned using X11 forwarding #234

Open dsfenn opened 7 months ago

dsfenn commented 7 months ago

I'm running Julia on a headless server, with X11 forwarding, using GLFW 3.4.1. When using either a Linux or Windows client, I get this error:

julia> window = GLFW.CreateWindow(640, 480, "GLFW.jl")
ERROR: GLFWError (API_UNAVAILABLE): GLX: No GLXFBConfigs returned
Stacktrace:

In case it's relevant, I'm able to run glxgears fine.

Also, in case it's relevant, here's the output of glxinfo:

Thanks

EDIT: This post initially stated that this problem only occurred using a Windows client, as I seemed to have success with a Linux client at the beginning. However, it's now not working for either Windows or Linux, so I've edited the post to reflect that.

I am also getting the exact same error when attempting to use X forwarding between a windows and linux machine, also with GLFW 3.4.1 (I can also run glxgears fine, and X forwarding is working with WGLMakie and python plotting libraries). Anyone have any suggestions?
