為什麼滑鼠遊標在螢幕右邊緣時會跳躍，導致奇怪的應用程式行為（例如 eclipse）？

當我將滑鼠移到螢幕右邊緣時，無論進入右邊緣時的垂直位置如何，它都會跳到螢幕右邊緣頂部向下約 25% 的點。

此後，我注意到 Eclipse 中出現了奇怪的行為，上下文選單在錯誤的位置彈出（通常在遊標左側很遠的地方）。重新啟動 Eclipse 後，Eclipse 中的問題消失了，但在我第一次移動到螢幕右邊緣時又出現了。

我的系統是 Mageia 8、Plasma 桌面、Breeze 主題、Linux 5.10.41、AMD64（Ryzen Threadripper 3960X 24 核心處理器），配備兩個 NVIDIA GPU（GeForce RTX 2080 SUPER），連接一台 4k 顯示器。

滑鼠跳轉總是發生，與 Eclipse 是否運作無關。

答案1

造成此問題的原因是我的 xorg.conf 配置了兩個螢幕，但我只連接了一台顯示器。

這是我原來的 xorg.conf：

如果我註解掉Screen該部分中的第二個部分，並在最後ServerLayout註解​​掉第二個部分的定義，則問題將得到解決（重新啟動後）。Screen滑鼠不再在邊緣跳躍，並且 Eclipse 上下文選單始終在遊標下方彈出。

答案2

感謝您展示瞭如何修復遊標穿過螢幕右邊緣的問題。有一個簡單的解決方案：將 screen2 定義中的 替換為 ，RightOf "screen1"保持0 0其他所有不變。您可以使用您最喜歡的文字編輯器來執行此操作（我使用 gedit），但請記住您必須是超級使用者。 CLI指令是： $ sudo gedit /etc/X11/xorg.conf然後尋找、取代、儲存並重新啟動。
