Fedora19——鼠标指针突然消失

我正在运行一台装有 Fedora19、Gnome3、双显示器（左 30 英寸，右 27 英寸）的台式机。

有时我的鼠标指针会从主屏幕上消失。如果我将鼠标移至辅助屏幕，它会正常显示和移动，但会显示为如下所示的乱码图标：

鼠标指针乱码

这种情况在我工作的过程中随机发生。尽管它似乎通常发生在我移动鼠标时（例如将焦点更改到另一个窗口）而不是在键盘上打字时。无论如何，这并不是由于系统像其他类似问题一样处于挂起或休眠状态。

当发生这种情况时，到目前为止我还没有找到任何方法来恢复鼠标指针。我发现在这个答案关于如何将指针设置到其他图标的想法，我一定会在下次发生这种情况时尝试。但到目前为止，即使切换用户，或者注销并重新登录也无法改变这种情况：30英寸屏幕上看不到鼠标，27英寸屏幕上显示乱码。不知道有什么更好的解决办法，只能重启。

有任何想法吗？
