脚本自动通过 SSH 转发 X 进程

我一直在尝试设置 conky 来监控我的家庭服务器的一些基本统计数据（处理器/内存使用情况、硬盘使用情况等）。

今天经历了很多混乱之后，我设法通过通过登录来使该过程正常工作

screen ssh -X 

然后运行

conky -c /path/to/config

然后，conky 进程在我的笔记本电脑上启动，即使我关闭了 ssh 会话，它也会持续存在。

但是我试图让这个从我笔记本电脑上的脚本开始，这样我就可以在启动时自动运行它。

我已经设置了一个通过没有密码的密钥登录的用户，以尝试使其全部正常工作（最终我的目标是尝试让它在我登录并开始过程时简单地询问密码）但我只是无法让它工作。

我正在使用的脚本是

#/bin/bash
screen ssh -X myconkyuser@myserverip "conky -c /path/to/config"

但它只是拒绝显示 conky。

甚至手动输入

screen ssh -X myconkyuser@myserverip "conky -c /path/to/config" 

从终端不会这样做。

如果我做

screen ssh -X -vv myconkyuser@myserverip "conky -c /path/to/config" 

我可以看到 ssh 连接正在发生并且 conky 正在启动，它只是没有正确地传递到我的笔记本电脑的 x 服务器。

我还尝试将其conky -c /path/to/config 作为自己的脚本放在服务器上并使用

screen ssh -X myconkyuser@myserverip "sh /path/to/conkystartupscript" 

但结果是一样的。

我将附加输出-vv以查看它是否可以阐明任何问题，我猜问题可能是会话在 conky 进程实际输出到显示器之前关闭，但我尝试pause 10在 conky 线下方添加无济于事。

任何人都可以帮忙吗？

conky 文件中有一些语法错误（这是一个非常旧的文件，但它完成了我想要的工作）但我认为它们不会导致问题，就像我ssh -X进入服务器然后启动 conky 一切都按预期工作.

（注意上面的代码输出没有使用屏幕，因为使用屏幕清除终端。看起来它正在经历基本相同的过程）
