今天，當我打開 Manjaro KDE 桌面時，面板/任務欄完全消失，我無法右鍵單擊桌面。我仍然能夠運行 Yakuke，以便能夠訪問終端，但是當我從終端運行應用程式時，它們會出現延遲，導致同一視窗的數十個副本留下。當我關閉視窗時，它保留在螢幕上。
我已經更新了我的系統pacman並在線嘗試了幾種解決方案，包括類似但舊的超級用戶貼文（誰的貢獻者不再活躍），儘管沒有一個解決方案對我有用。如有必要，我很樂意提供任何額外的輸出。
plasmashell這是我從終端運行時的輸出：

答案1
當電腦上曾經正常工作的某些內容突然停止工作時，第一個問題應該是「發生了什麼變化？」。
問題可能是硬體問題，但通常是軟體問題。人們應該先尋找以下任何一項：
- 安裝新產品或更新現有產品
- 驅動程式更新
- 作業系統升級。
如果上述任何情況發生在問題開始之前，則立即測試是撤銷變更。如果是驅動程序，則應從設備中卸載它和從作業系統（或它將在重新啟動時返回）。
撤銷變更後，重新啟動並測試問題是否消失。如果成功，應阻止此更新再次返回。
在這篇文章中，問題是由安裝網路印表機引起的。
答案2
該問題是由我透過 Web 介面新增到 CUPS 的網路印表機引起的。我透過以下方式存取了網路介面http://本地主機:631/並刪除了我新增的印表機。我不確定為什麼這會導致等離子外殼崩潰，但這修復了分段錯誤。我已經打開了一個錯誤https://bugs.kde.org/為此要找到根本原因。
