无法从 SSH 启动 MonoGame，但可以从 GUI 启动

Question

所以我想从我的 SSH 终端开始游戏。

它真的很奇怪，当我直接从我的 linux GUI 执行此操作时，它可以工作。但是当我使用 SSH 客户端从远处连接时，它就会崩溃。似乎与我的显示驱动程序有关。

虽然我创建了一个 bash 脚本，然后它会调用自己的启动游戏的方法来完成这项工作，但不幸的是它会产生相同的结果。

基本上，当我在我的 linux GUI 中运行 SAME EXACT 命令时，游戏开始时没有问题，但是当我在我的 SSH 中从远处运行 SAME EXACT 命令时，游戏没有启动，它只是卡在那里。

mono /home/pi/.../game/TestGame.exe

我在树莓派上运行 Linux Raspbian。 我的树莓派连接在我的屏幕上。当插入我的键盘时，它会启动，当我使用 ssh 从我的另一台计算机上尝试时，它会崩溃并给出我们在此处看到的错误。

我将不胜感激。

非常感谢！ 凯文

跟进我的发现，

如果你犯了这个错误，有两件事要看：

1. 检查您是否在 SSH 终端中激活了 X11 转发。

2. 键入这个神奇的行来告诉 SSH 使用哪个监视器。否则任何图形软件都会在启动时崩溃。

   导出 DISPLAY=:0

谢谢， 凯夫
