误删除Ubuntu 14桌面文件夹“~/桌面”，如何恢复？

一不小心把当前用户的桌面文件夹“/home/wenjianbao/桌面”删了，导致系统把“/home/wenjianbao”当成桌面文件夹。结果，桌面上全是乱七八糟的文件/文件夹。

查看了下网络资料，可以通过修改 ～/.config/user-dirs.dirs 中的 XDG_DESKTOP_DIR 来重新指定“桌面文件夹”：

# 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="$HOME/下载"
XDG_TEMPLATES_DIR="$HOME/模板"
XDG_PUBLICSHARE_DIR="$HOME/公共的"
XDG_DOCUMENTS_DIR="$HOME/文档"
XDG_MUSIC_DIR="$HOME/音乐"
XDG_PICTURES_DIR="$HOME/图片"
XDG_VIDEOS_DIR="$HOME/视频"
