无法通过 SSH 使 gnome-session 工作

要通过 ssh 从我的家庭计算机登录我的办公室计算机，我需要执行以下两个步骤：首先登录到我的办公室服务器：ssh -X myOfficeServerID@myofficeServer然后使用本地 IP 登录到我的计算机：ssh -X myOfficeComputerID@myOfficeComputerIP。我希望能够远程查看我的桌面并使用 GUI。

这是运行的结果gnome-session：

这些命令将继续不间断地运行，直到我按下 ^C，正如您在命令中看到的那样：

Initializing nautilus-gdu extension
Initializing nautilus-open-terminal extension
Initializing nautilus-dropbox 1.4.0
Shutting down dropbox extension
Shutting down nautilus-open-terminal extension
Shutting down nautilus-gdu extension

与此同时，诸如firefox从我的办公室计算机运行的东西，但底部面板不会停止加载东西。

答案1

两个 SSH 会话都需要使用 -X 选项启动。

但是，如果您想要整个会话，您可能需要考虑使用类似的东西X2go因为它压缩图像并有一些代理，这使得带宽消耗少很多并且它可以恢复会话......

当您的远程 gnome 会话启动远程元城市来取代本地窗口管理器时，运行整个 gnome 会话可能会产生令人不快的副作用。

您的附加信息显示了我提到的“令人不快的副作用”。当你已经有一个正在运行的桌面环境时，你不能简单地运行gnome-session，因为 gnome-session 会尝试接管，而你正在运行的桌面环境不会那么容易让它这么做。对于 X 程序来说，无论是通过 SSH 远程运行还是在本地运行，都没有什么区别。

根据您想要实现的目标，您可以启动一个xnest会话并将其用于远程 gnome 会话。

xnest -geometry 1280x1024 :123 &
DISPLAY=:123 ssh -X firsthop
ssh -X secondhop
gnome-session

注意：在某些发行版中，二进制文件Xnest以大写 x 命名。

答案2

我遇到了同样的错误，打开了一堆文件浏览器（nautilus）实例，但我无法正确连接到我的帐户。

我今天发现的原因是，我的 ~.cshrc 中有这一行：“setenv DISPLAY unix:0.0”

注释掉之后，一切正常。因此，显然通过 ssh 连接时显示设置了两次，每个 ssh 一次，每个 user-cshrc 一次，导致一些混乱。

答案3

图形会话无法通过 SSH 启动，您需要使用 VNC 服务器或远程桌面连接。 SSH 只会为您提供 shell 访问权限，因为您登录计算机的方式不允许您将 gnome-session 打开到您可以访问的 X-Session 中。因此，如果您的目标是获得完整的图形桌面（可以通过 RealVNC 等 VNC 查看器连接到该桌面），请使用 VNC。您可以通过安装在您的计算机上设置 VNC 服务器tightvncserver。安装后，您可以通过在 shell 中输入以下内容来启动 VNC 服务器tightvnc

    username@hostname $tightvncserver --geometry 1024x760

答案4

也许您刚刚忘记了命令：（xhost + 就在 ssh 命令之前：）ssh -XY username@servername。
