【问题描述】：
目前我正在尝试通过 ssh 使用 x11 远程运行 Intellij Idea，这样我就可以在我的个人 iMac 上看到这些小部件，但 IDE 实际上是在我发布的 MacPro 上运行的。这样一来，我就可以在电晕爆发期间在家中使用尺寸合适的显示器工作，而不会违反公司关于个人计算机上与工作相关的代码的政策。为此，我在工作机器上运行的 SSH 守护程序上启用了 X11 转发，并在两台机器上安装了 xquartz。从我的家用机器上，我可以 ssh 进入我的工作机器并运行 xclock 和 xeyes 等 x11 程序，没有任何问题。当我尝试运行 Idea 时，出现异常：

我尝试设置一个idea.vmoptions -Djava.awt.headless=false 来帮助它找出实际上有一个远程显示设备，但这无济于事。欢迎任何帮助。我确信我不是唯一一个在家工作并遇到这个问题的人。
【问题讨论】：
-
您需要 X Window 服务器环境和
export DISPLAY=:0才能运行 GUI 应用程序。您可以运行任何其他 Java Swing 应用程序，例如 JEdit 或 NetBeans 吗？ -
就像我说的其他 GUI 程序，即 xclock 和 xeyes 也可以工作。为什么idea不应该工作呢？ Jetbrains 确实支持 x11

IntelliJ IDEA 可能看不到您的
DISPLAY环境变量。尝试从终端运行：export DISPLAY=:0，然后是/Applications/IntelliJ\ IDEA.app/Contents/MacOS/idea。见stackoverflow.com/a/26586170/104891。还要检查这个答案是否有帮助：stackoverflow.com/a/26224404/104891. -
intellij 的 macos 版本可能不支持 X。毕竟，Macos 自己的 GUI 不是基于 X 的。使用屏幕共享可能会带来更好的运气。
