X11 apps can still run under Wayland through the XWayland compatibility layer. 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 -This sounds great. Wayland is a replacement for X11 so I would rather use it instead of X with XWayland. Wayland native apps work better with my window manager, and behave more consistently. Unfortunately, in practice **SDL does not use Wayland**. My SDL windows open using X. I don't know if it's a problem with my environment, but here's how I fixed it (for c++). +However if your compositor does not implement the `wp_fifo_manager_v1` protocol, SDL will fall back to XWayland. I don't know the details how this protocol fits into the Wayland ecosystem but my compositor doesn't have it. 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") { @@ -17,5 +18,5 @@ for (int i = 0; i < SDL_GetNumVideoDrivers(); i++) { } } ``` -This code will explicitly enable Wayland if it is available.
