我尝试打开 vlc 或 snap-store，但它们无法打开。尝试通过终端打开后，我收到以下错误，如下所示。vlc 错误：

谁能分享一些关于如何修复这些权限被拒绝错误的见解。
答案1
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 DISPLAY 变量并xhost +以该用户身份运行，以允许其他用户访问 Xserver。
对于 snap，您必须将添加export DISPLAY=$YourDisplayValue到运行 snap 命令的用户 .bashrc 中。
我不记得如何以编程方式执行此值以使其更具可移植性，但它通常不会发生太大变化。显然，将环境传递给 snap 应用程序有点困难。
但这在当前的 20.04 上对我有用
