No available video device - Any way to use the library on headless ubuntu server?

[slunak]

Hello folks.

Is there any way to use the library on a Ubuntu Server without a display?

if err := sdl.Init(sdl.INIT_VIDEO); err != nil {
    println(err.Error())
    return
}

Gives the following error: No available video device, which is expected.

The reason I would like to use the library on headless ubuntu is to only generate graphics with SDL and later simply copy it to LED matrix display, pixel by pixel.

Set the environment variable SDL_VIDEODRIVER=dummy

(It's SDL_VIDEO_DRIVER in SDL3.)

Does it apply to SDL2? I'm afraid Go binding currently supports only version 2.

Yes. One less underscore in the variable name.

Sorry, I missed to see the difference between the two vars in your first reply; it was either late last night or perhaps because I was looking at it from my mobile phone :) in any case, thank you very much. Feel free to close this issue.
