SSHを介してgnome-sessionを機能させることはできません

マイホームコンピュータからSSH経由でマイオフィスコンピュータにログインするには、次の2つの手順を実行する必要があります。まず、私のオフィスサーバーにログインします。ssh -X myOfficeServerID@myofficeServer次に、ローカルIPを使用してマイコンピュータにログインしますssh -X myOfficeComputerID@myOfficeComputerIP。私のデスクトップをリモートで見て、GUIを使用できるようにしたいです。

これは実行結果ですgnome-session。

同時に、私のオフィスのコンピュータで実行するのと似ていますfirefoxが、下部パネルからアイテムの読み込みが中断されることはありません。

両方のSSHセッションは、-Xオプションを使用して開始する必要があります。

ただし、セッション全体が必要な場合は、次のようなものを使用することをお勧めします。X投稿イメージを圧縮し、いくつかのプロキシが含まれているため、帯域幅の消費が大幅に削減され、セッションを再開できます。

リモートgnomeセッションがローカルウィンドウマネージャの代わりにリモートメタシティを起動したときにgnomeセッション全体を実行すると、不快な副作用が発生する可能性があります。

あなたの追加情報には、私が言及した「不快な副作用」が記載されています。gnome-sessiongnome-sessionが引き継ぎを試み、実行中のデスクトップ環境ではこれを簡単に実行できないため、すでに実行中のデスクトップ環境がある場合は簡単に実行することはできません。 XプログラムがSSHを介してリモートで実行されるのか、ローカルで実行されるのかは異なりません。

達成したい目標に応じてxnestセッションを開始し、リモートgnomeセッションで使用できます。

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

注：一部のディストリビューションでは、バイナリ名はXnest大文字xで指定されています。
