VLC和Snap-Store在ubuntu 20.04中不打开并显示错误权限。

我试着打开vlc或snap-商店，但它们没有打开。在尝试打开终端之后，我得到了如下错误：vlc错误：

对于大多数X11 gui应用程序，您可以导出运行Xserver的用户的相同显示变量，并运行xhost +作为该用户允许其他用户访问Xserver。

对于snap，必须将export DISPLAY=$YourDisplayValue添加到运行snap命令的用户.bashrc中。

我不记得如何通过编程实现这个值，以使其更可移植，但它通常不会改变那么多。显然，通过环境来抓取应用程序是一项任务。

但这件事对我来说很管用
