Ubuntu12.04からWebExミーティングに参加しようとしています。参加できますが、ライブチャットメッセージが表示されず、音も聞こえず、プレゼンテーションも表示されません。 Ubuntu12.0464ビットおよび32ビットを使用してみました。一度動作させることができたときは、32ビットで、サウンドは数分間動作しましたが、その後停止しました。プレゼンテーションは表示されましたが、チャットメッセージは表示されませんでした。 2013年5月28日現在、webupd8PPAからOracleJava 7をインストールし、すべてのUbuntuアップデートをダウンロードしました。
WebExシステム要件ページには、Ubuntu10.xまたは11.x32ビットが必要であると記載されています。これは、2013年5月にUbuntu 12.04をサポートしないことを意味しますか？！？
5月29日更新：古いシステム要件を調べていたようです。これらは現在のWebExシステム要件のようです。つまり、「WebExは、次の最小要件を満たしている限り、すべてのLinuxディストリビューションをサポートします。
- カーネル：2.6以降
- X Lib：X11R6以降と互換性があります
- C ++ Lib：libstdc ++ 6
- デスクトップ環境、XFce 4.0以降、KDE、Ximian、Gnome
- GDK/GTK。バージョン：2.0以降
- Glib：2.0以降
- SunJava1.5以降」
私はまだUbuntuとLinuxについて学んでいますが、Ubuntu 12.04には新しいカーネル（3.2）が付属し、X11ウィンドウマネージャーを使用し、UnityはGnomeに基づいており、OracleJava7をインストールしました。これらの他のパッケージには非常に多くのオプションがあるため、私は少し混乱しています。私の問題は、これらのパッケージや互換性のないバージョンが1つ以上ないことだと思います。誰かがこれについて何か洞察を持っていますか？
更新5月30日午前10時EST。ここで推奨されているようにia32-libsをインストールしてみました。同じ問題。 Javaコンソールを有効にしました。出力は次のとおりです：

関連：dpkgエラー：「ファイルを上書きしようとしていますが、これも…にあります」他の投稿から多くの手順と推奨事項を試しましたが、Firefox（Ubuntu 16.04 64ビット）では何も機能しませんでした。
Webexを完全に機能させる唯一の方法は、VirtualBoxをインストールしてから、Windowsを仮想OSとしてインストールすることでした。はい、Webexが必要になるたびに仮想OSを実行するのは少し不便ですが、完全に機能することを100％確信できます（音声、ビデオ、画面共有）。
