我一直在尝试设置 conky 来从我的家庭服务器监控一些基本统计数据（处理器/内存使用情况、硬盘使用情况等）。
今天经过一番折腾，我终于设法通过以下方式登录，让流程正常运行：
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，并且即使我关闭 ssh 会话后它仍会继续存在。
不过，我试图让它从我的笔记本电脑上的脚本启动，以便可以在启动时自动运行它。
我已经设置了一个通过密钥登录的用户，无需密码，以尝试让一切正常工作（最终我的目标是尝试让它在我登录并开始该过程时简单地要求输入密码）但我就是无法让它工作。
我使用的脚本是
#/bin/bash
screen ssh -X myconkyuser@myserverip "conky -c /path/to/config"
但它就是拒绝显示 conky。
即使手动输入
screen ssh -X myconkyuser@myserverip "conky -c /path/to/config"
从终端执行此操作是不行的。
如果我做
screen ssh -X -vv myconkyuser@myserverip "conky -c /path/to/config"
我可以看到 ssh 连接正在进行并且 conky 正在启动，但它没有被正确传递到我的笔记本电脑的 x 服务器。
我也尝试将其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。
我将附上输出-vv以查看它是否可以提供任何线索，我猜测问题可能是在 conky 进程实际输出到显示器之前会话正在关闭，但我尝试在pause 10conky 行下方添加但无济于事。
有人可以帮忙吗？

conky 文件中存在一些语法错误（这是一个非常旧的文件，但它完成了我想要的工作）但我不认为它们导致了问题，因为如果我ssh -X进入服务器然后启动 conky，一切都会按预期工作。
（注意：上面的代码输出没有使用屏幕，因为使用屏幕会清除终端。但它看起来基本上经历了相同的过程）
答案1
好的，我似乎已经解决了这个问题。这似乎是在 x 进程转发之前关闭连接的问题。我还发现“screen”命令在终端外运行的脚本中不起作用。
我的新脚本是
#!/bin/bash
sleep 25 && (to ensure my desktop gets a chance to boot before running)
conky -c ~/.conky/.conkynewrc && (my local conky session)
ssh -X willconky@myserverip "conky -c /home/willconky/.conky/.conkynewrc && sleep 10" & (my remote conky session)
现在看来一切都运行正常。
