Ubuntu Mate 16.04のxRDP-接続エラー

Dell Optiplex 780へのUbuntu Mate 16.04の新規インストールおよび更新。

Windows 10クライアントからの接続。

直後にxRDPをインストールし、Windowsから接続しようとした。

RDPセッションに入り、資格情報を入力しました。その後...

このエラーが発生しました。

Connecting to sesman IP 127.0.0.1 port 3350
sesman connect ok

srdp_mm_process_login_response:login successful for display

このコマンドを実行しました

:~$ Sudo netstat -peant | grep "127.0.0.1"

そして得た：

tcp        0      0 127.0.0.1:3350          0.0.0.0:*              LISTEN      0          39396       8082/xrdp-sesman

同じことをgrepping "5910"で試したところ、何も返されませんでした。

Xrdpを削除してから、tightvncserverを最初にインストールし、vncデスクトップ接続を作成してから、xRDPをインストールしようとしました。

私は他のコンピューターでVNCを使用していて、xRDPを発見し、xDRPをインストールし、：1デスクトップを強制終了し、わずかな問題もなくxRDPを使用できました。

このデスクトップでは、systemctlチェックの結果、xRDPサービスは問題なく実行されていました。

接続を試みた後、私の/ var/log/syslogを表示したところ、次のような結果になりました。

このスレッドからいくつかのアイデアを得ました、

エラー/問題の接続（Windows 10 RDPからXRDPへ）

これを参照するもの...

https://ubuntuforums.org/showthread.php?t=1314336

しかし、サイコロはありません。

Mateで別のことをする必要がありますか？

これを別のスレッドに投稿する必要がありますか？

助けてくれ、Ubuntu Mates！

更新！

何も変更せず、再起動しました。初めて同じエラーが発生しましたが、その後...

これで、以前のエラーなしでxRDPログインプロンプトから完全にログインできるようになりましたが、この灰色のピクセル化された画面が表示されます。

すごい！思ったよりずっと簡単。この単純なxstartupディレクティブとブーム、低CPU使用率、優れた接続を使用しました。

#!/bin/bash
xrdb $HOME/.Xresources
startmate &

私は明らかにこれを考えすぎていて、適切にセットアップをしていませんでした。

今私は知っています：

  1. tightvncをインストールする
  2. 起動：1デスクトップ、次にkillして〜/ .vncディレクトリと構成を作成
  3. xstartupディレクティブが上記の非常に基本的な3ライナーであることを確認し、必要に応じて上書きします。
  4. xrdpをインストールする
  5. ：1デスクトップを再度起動します
  6. 私のお気に入りのRDPクライアントであるRemminaを使用して接続してください！
  7. 新しいものを試し、間違いを犯し、それについてguyzizに質問し、トラブルシューティングを行って、どういうわけかそれを機能させて、「Nixの動作の詳細を学んでください！

ありがとう、Ubuntu Mates！
