Couldn't find matching GLX visual

[carlomilanesi]

When running the downloaded executable program, I get this error:

kalast<0.4.3> (built on 2024-01-18T00:16:18Z with rustc<1.75.0>)
Config initialized at /home/<user>/Downloads/kalast-v0.4.3-ubuntu
thread 'main' panicked at src/win/window.rs:114:36:
called `Result::unwrap()` on an `Err` value: SdlError("Couldn't find matching GLX visual")
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

When running the example from source code, I get a similar error message.

Hi @carlomilanesi, thank for filing the issue!

I just tested on Ubuntu and here are the screenshot of the program running with glxinfo command to check version of OpenGL. Do you have the same on your side?

[carlomilanesi]

Yes. I have:

$ ls
assets  cfg  examples  kalast  kalast.ico  preferences.yaml  README.md
$ glxinfo | grep "OpenGL version"
OpenGL version string: 4.6 (Compatibility Profile) Mesa 23.0.4-0ubuntu1~22.04.1

Though, ./kalast does not work. I use Linux Mint with Cinnamon desktop.
