我使用的是 kubuntu 15.04。突然（沒有進行升級），當我登入時，我的等離子無法啟動。我在桌面上打開了應用程序，但沒有面板、沒有選單、沒有背景。
sudo Plasshell 可以工作（但以 root 身分運行），而不是以普通使用者身分執行。我現在會嘗試升級，但我有點擔心我應該先解決這個問題。也許我應該檢查特定的日誌？
這可能是權限問題嗎？我一直使用Dolphin作為root來解決備份的寫入權限問題，也許這是一個壞主意。

我將 /home/me 中所有文件的所有權更改為我自己。之後，嘗試執行plasmashell：

我最近在 .bashrc 中設定了 DL_LIBRARY_PATH 變數。這會幹擾嗎？ （看著這錯誤報告）

我已經創建了一個新用戶。 Plasma 非常適合該用戶。必須再次進行所有桌面設定有點煩人，但好吧......我猜這是一個權限問題？沒有線索...
答案1
肯定是權限問題。我已經設法打開用戶管理器（恰好打開的 konsole 中的 sudo Plasshell（感謝上帝）和系統設定）。創建一個新用戶（並使用該用戶登入）似乎已經解決了這個問題。
後來我愚蠢地做了 sudo chown -R me /home/me ，它又搞砸了！經過 10 年的 Linux 使用，我應該知道這一點。隱藏檔案的權限很重要...
