On Linux, it compiles with support for both [X Window System](https://www.x.org/wiki/) and [Wayland](https://wayland.freedesktop.org/). This is great because it makes your app compatible with just about any desktop environment or window manager. In the [SDL3 documentation](https://wiki.libsdl.org/SDL3/README-wayland) it says that +> Wayland is a replacement for the X11 window system protocol and architecture and is favored over X11 by default in SDL3 + +However, if your compositor does not implement the `wp_fifo_manager_v1` protocol SDL will fall back to XWayland. My compositor doesn't have it, and here's how I forced SDL to use Wayland anyway (for c++). +```c++ +for (int i = 0; i < SDL_GetNumVideoDrivers(); i++) { + if (std::string(SDL_GetVideoDriver(i)) == "wayland") { + SDL_SetHintWithPriority(SDL_HINT_VIDEO_DRIVER, "wayland", SDL_HINT_OVERRIDE); + break; + } +} +``` +This code will explicitly enable Wayland if it is available. |
