I've been unable to hide the mouse cursor (properly) using SDL. I am using Ubuntu 10.10 and have been using the following:

SDL_ShowCursor( SDL_DISABLE );
SDL_WarpMouse( x, y );

Neither of which function properly at all; it would appear to have no visual effect, there is however a triggered mouse motion event as the documentation states, but the mouse does not move in any or disappear on screen.

The SDL Window is created (via SDL_CreateWindow) with the flags SDL_WINDOW_OPENGL | SDL_WINDOW_SHOWN. Fullscreen has no effect on the outcome.

Running the window at low resolutions in fullscreen mode (such as 640x480), does provide the desired effect of the commands; but the cursor bleeds through from the underlying windows.
Around 1024x768, it has a completely different cursor icon.
As I get higher in resolution, it stops bleeding through and just acts as though its a window (the Gnome cursor). With no effect of above commands.

Any ideas?

Yes, cursors are not yet implemented in SDL 1.3.  I'm sort of intentionally leaving them unimplemented as a reminder that 1.3 isn't ready yet.

However, as soon as I finish my fullscreen work I'll be working on them, so soon now! :)
