  Here's what I use to set the cursor position (in screen coordinates).
You might also want to take a look at gdk_pointer_grab () to confine the
cursor inside a window.

void Sys_SetCursorPos (int x, int y)
{
#ifdef WIN32
  SetCursorPos (x, y);
#endif
 
#ifdef __linux__
  XWarpPointer (GDK_DISPLAY(), None, GDK_ROOT_WINDOW(), 0, 0, 0, 0, x,
y);
#endif
}
