Ssh
無法讓 gnome-session 通過 SSH 工作
要通過 ssh 從我的家用電腦登錄我的辦公室電腦，我需要執行以下兩個步驟：首先我登錄到我的辦公室伺服器：
ssh -X myOfficeServerID@myofficeServer然後我使用本地 IP 登錄到我的電腦：ssh -X myOfficeComputerID@myOfficeComputerIP。我希望能夠遠端查看我的桌面並使用 GUI。這是執行的結果

兩個 SSH 會話都需要使用 -X 選項啟動。
但是，如果您想要整個會話，您可能需要考慮使用X2go之類的東西，因為它會壓縮圖像並且有一些代理可以減少頻寬消耗並且它可以恢復會話……
當您的遠端 gnome-session 啟動一個替換您本地視窗管理器的遠端 metacity 時，執行整個 gnome-session 可能會產生令人不快的副作用。
您的附加資訊顯示了我提到的“令人不快的副作用”。當你已經有一個桌面環境正在執行時，你不能簡單地執行
gnome-session，因為 gnome-session 會嘗試接管，而你正在執行的桌面環境不會那麼容易。對於 X 程序，無論是通過 SSH 遠端執行還是本地執行，都沒有區別。根據您想要實現的目標，您可以啟動一個
xnest會話並將其用於您的遠端 gnome 會話。xnest -geometry 1280x1024 :123 & DISPLAY=:123 ssh -X firsthop ssh -X secondhop gnome-session注意：在某些發行版中，二進製文件以
Xnest大寫 x 命名。
