Ubuntu 20.04下以root身份启动VSCode失败求助

我在Ubuntu 20.04系统中通过snap安装了VSCode 1.79.2版本，尝试使用命令sudo code --verbose --user-data-dir=/root/.config/Code --no-sandbox以root身份启动VSCode时，仅弹出空白窗口。以下是相关日志信息，恳请各位提供帮助：

从日志中的No protocol specified和xcb连接失败错误来看，问题核心是root用户未获取X服务器访问权限，同时Snap沙箱限制也可能加剧问题。可尝试以下步骤解决：

• 步骤1：允许root访问当前用户的X显示
  在普通用户终端执行命令，授予root访问X服务器的权限：

  xhost +si:localuser:root
  

• 步骤2：调整启动命令，指定DISPLAY环境变量
  使用以下命令启动VSCode，明确传递当前用户的显示参数：

  sudo DISPLAY=$DISPLAY code --verbose --user-data-dir=/root/.config/Code --no-sandbox
  

• 步骤3：配置Snap权限（可选）
  若上述方法无效，给VSCode的Snap包添加必要的访问权限：

  sudo snap connect code:home :home
  sudo snap connect code:x11 :x11
  

• 步骤4：优先避免以root身份运行VSCode（推荐）
  除非必须，不建议用root启动VSCode。可通过修改目标文件/目录的权限，让普通用户拥有读写权限，无需root即可操作。
