一不小心把當前用戶的桌面文件夾“/home/wenjianbao/桌面”刪了，導致系統把“/home/wenjianbao”當成桌面文件夾。結果，桌面上全是亂七八糟的文件/文件夾。
查看了下網絡資料，可以通過修改 ～/.config/user-dirs.dirs 中的 XDG_DESKTOP_DIR 來重新指定“桌面文件夾”：
# This file is written by xdg-user-dirs-update # If you want to change or add directories, just edit the line you're # interested in. All local changes will be retained on the next run # Format is XDG_xxx_DIR="$HOME/yyy", where yyy is a shell-escaped # homedir-relative path, or XDG_xxx_DIR="/yyy", where /yyy is an # absolute path. No other format is supported. # XDG_DESKTOP_DIR="$HOME/桌面" XDG_DOWNLOAD_DIR="$HOME/下載" XDG_TEMPLATES_DIR="$HOME/模板" XDG_PUBLICSHARE_DIR="$HOME/公共的" XDG_DOCUMENTS_DIR="$HOME/文檔" XDG_MUSIC_DIR="$HOME/音樂" XDG_PICTURES_DIR="$HOME/圖片" XDG_VIDEOS_DIR="$HOME/視頻"
