我正在運行一台裝有 Fedora19、Gnome3、雙顯示器（左 30 英寸，右 27 英寸）的桌上型電腦。
有時我的滑鼠指標會從主螢幕上消失。如果我將滑鼠移至輔助螢幕，它會正常顯示和移動，但會顯示為如下所示的亂碼圖示：
這種情況在我工作的過程中隨機發生。儘管它似乎通常發生在我移動滑鼠時（例如將焦點更改到另一個視窗）而不是在鍵盤上打字時。無論如何，這並不是由於系統像其他類似問題一樣處於掛起或休眠狀態。
當發生這種情況時，到目前為止我還沒有找到任何方法來恢復滑鼠指標。我發現在這個答案關於如何將指標設定到其他圖示的想法，我一定會在下次發生這種情況時嘗試。但到目前為止，即使切換用戶，或登出並重新登入也無法改變這種情況：30吋螢幕上看不到滑鼠，27吋螢幕上顯示亂碼。不知道有什麼更好的解決辦法，只能重啟。
有任何想法嗎？
