vncserverを有効にできない #6

Open masuko-shingo opened 3 years ago

masuko-shingo commented 3 years ago

経緯

写真に残したコマンドを試して、一度はPC(ubuntu)とjetsonnano間でvncを接続できたので、
Windowsでvncseverを起動しようとした際の試行錯誤で、今の状況になった。 ubuntuで、端末を立ち上げなおし、コマンドを実行したところ vncserverの起動まではできたように思える。

以下ログ

PC(ubuntu-remmina)ーjetsonnano間でのvnc接続

ubuntuで端末を開き ssh通信でjetsonnanoにログイン

$ sudo vncpasswd
$ sudo vncserver
$ sudo vncserver -display :0 -passwordfile ~/.vnc/passwd
$ vncserver -display :0 -passwordfile ~/.vnc/passwd
$ vncserver -display :1 -passwordfile ~/.vnc/passwd
$ x0vncserver -display :0 -passwordfile ~/.vnc/passwd
$ x0vncserver -display :1 -passwordfile ~/.vnc/passwd

上記のコマンドを実行して vncserverを有効にするこの時

$ sudo vncpasswd

を入力しても特に何もメッセージは返されなかった。 (先生が設定した情報が残っていた？) 他は、写真に残したメッセージとほとんど変わらなかった。

ubuntu側でホットキーを押し、検索バーにvncと入力 remmineを開き vncに設定して JetsonnanoのIPアドレスを入力接続ができた。 ubuntuとjetsonnano間でのvnc接続を確認できたので、 WSLとJetsonnano間でのvnc接続を試す

PC(windows)とJetsonnano間でのvnc接続

realVNCviewerをインストールする https://www.realvnc.com/en/connect/download/viewer/ ホットキーを押し、検索バーにubuntuと入力

$ sudo vncpasswd
pass:turtlebot
$ sudo vncserver
$ sudo vncserver -display :0 -passwordfile ~/.vnc/passwd
$ vncserver -display :0 -passwordfile ~/.vnc/passwd
$ vncserver -display :1 -passwordfile ~/.vnc/passwd
$ x0vncserver -display :0 -passwordfile ~/.vnc/passwd
$ x0vncserver -display :1 -passwordfile ~/.vnc/passwd

この際

$ sudo vncpasswd
Password:
Verify:
sorry please try again

となり、うまく設定できなかった。試行錯誤の際に

/home/jetsonnano/.vnc/passwd

上記のファイルを消去してしまった。その後

$ touch passwd

でファイルを作成し直した再度

$ sudo vncpasswd
pass:turtlebot
$ sudo vncserver
$ sudo vncserver -display :0 -passwordfile ~/.vnc/passwd
$ vncserver -display :0 -passwordfile ~/.vnc/passwd
$ vncserver -display :1 -passwordfile ~/.vnc/passwd
$ x0vncserver -display :0 -passwordfile ~/.vnc/passwd
$ x0vncserver -display :1 -passwordfile ~/.vnc/passwd

これらのコマンドを実行したが、パスワードが設定されていないというメッセージが返された。

masuko-shingo commented 3 years ago

再度ubuntuでJetsonnanoにログインし、vncserverを立ち上げようと試すと

$ sudo vncpasswd
Password:
Verify:
Would you like to enter a view-only password (y/n)? n
$ sudo vncserver
vncserver: /usr/bin/Xtigervnc did not start up, please look into '/home/jetsonnano/.vnc/jetsonnano-desktop:1.log' to determine the reason! -2

とメッセージを返されるメッセージの通りファイルを確認

$ cd ~/.vnc
$ cat jetsonnano-desktop\:1.log

なるほどこれを見て理解しました．

$ sudo vncpasswd
$ sudo vncserver
$ sudo vncserver -display :0 -passwordfile ~/.vnc/passwd
$ vncserver -display :0 -passwordfile ~/.vnc/passwd
$ vncserver -display :1 -passwordfile ~/.vnc/passwd
$ x0vncserver -display :0 -passwordfile ~/.vnc/passwd
↑　不要
$ x0vncserver -display :1 -passwordfile ~/.vnc/passwd

ということで，以下のコマンドだけ実行すればOKです．

$ x0vncserver -display :1 -passwordfile ~/.vnc/passwd

ただし，displayの番号は環境で変化しますので，1以外の数字になることがあります．私も試行錯誤的に発見したものですので，このコマンドが何をしているのかを調べて使用したほうが良いです．（こちらを入力したときには時間切れでしたので，ほとんど調べずにネットのサンプルを入れただけですので．．．）

パスワードファイルにエラーがあります．

SVncAuth:    opening password file '/home/jetsonnano/.vnc/passwd' failed

masuko-shingo commented 3 years ago

一度このファイルを消去してしまったのが原因かと思っています。復元方法がわからなかったので、とりあえず、

$ touch passwd

でpasswdファイルを空ファイルで作成するという対処を行ったのですが、正しい復元ではないような気がしています。再インストールする方法か、フォーマットがわかれば書き込むことで、復元可能でしょうか？

yasuohayashibara commented 3 years ago

これだと空のpasswdファイルが生成されますので，正常に起動しないと思います．以下の記事を参考にしていますので，この通りに実行してみてください．（環境に応じて変更する必要があるところがありますが．．．）

yasuohayashibara commented 3 years ago

困ることがなければこちらで遠隔操作してみると良いと思います．確か目的は無線でJetsonNanoを操作したいということでしたよね？それができれば見え方が違っていても良いと思います．

あと，そもそも論でいうと，こちらの方が簡単だからということで試している話ですので，難しい場合は別の方法(別のPCで起動したros nodeをつなぐ）でも良いと思います．

masuko-shingo commented 3 years ago

接続はできているのですが、この状態では、rvizやgazeboが起動できない状態です。 SLAMやナビゲーション時、PCに画面を映して、様子を確認できないので、結局jetsonnanoにディスプレイを接続しないと、様子を確認できない形です。

gnome desktop 環境でvncserver を起動するには，passwdとxstartupのファイルが必要となります．何も用意しないまま，起動すると/usr/bin/xtermが呼ばれるので，https://github.com/masuko-shingo/jetson-nano/issues/6#issuecomment-910208733 のような画面で起動します．

現在gnome desktopが起動していないように見えるので，/etc/vnc/xstartupか$HOME/.vnc/xstartupが存在していない可能性が高いです．もし，gnome desktopの環境で起動したい場合には，gnome-sessionがvncserverのスタートアップのタイミングで呼ばれる必要があるので，xstartupファイルに記述すると立ち上がると思います．

また，x0vncserver と tigervncserver，vncserver のコマンドを併用して使用しているようですが，vncserverコマンドのみを利用することをおすすめします．

理由は，以下のようにシンボリックとなっているためです．

$ ls -l $(which vncserver)
lrwxrwxrwx 1 root root 27 Jun 16  2020 /usr/bin/vncserver -> /etc/alternatives/vncserver

$ ls -l /etc/alternatives/vncserver
lrwxrwxrwx 1 root root 23 Jun 16  2020 /etc/alternatives/vncserver -> /usr/bin/tigervncserver

masuko-shingo commented 3 years ago

xstartupファイルが存在するか確認したところ、
/etc/vnc/xstartup $HOME/.vnc/xstartupどちらも存在していませんでした。

xstartupファイルが存在しない場合は、作成して記述すれば問題ないでしょうか？作成方法、記述方法がわからず調べたところ、このようなサイトを発見したので試してみようかと思っているのですが、
問題ありませんでしょうか？サイト：http://safe-linux.homeip.net/other/linux-vnc-03.html

上記の$HOME/.vnc/xstartupでは，dbus-launchを介せずに起動しようとしているので，以下を参考に設定するといいとおもいます． https://www.answertopia.com/ubuntu/ubuntu-remote-desktop-access-with-vnc/

masuko-shingo commented 3 years ago

これらのサイトを参考にして、
https://www.answertopia.com/ubuntu/ubuntu-remote-desktop-access-with-vino/
https://www.hackster.io/news/getting-started-with-the-nvidia-jetson-nano-developer-kit-43aa7c298797
vinoインストールと、設定から画面共有を有効にしてvncを行いました。
jetsonnanoにディスプレイを繋いでいない状態でvncを行ったところ、 remmina(ubuntu)、realVNC(windows)どちらも接続できましたが、NVIDIAのロゴマークしか表示されないという状況です。 jetsonnanoにディスプレイを繋いだ状態では、 vncの画面が真っ黒な画面となり、ディスプレイはGUIが表示されました。どう対処すれば良いでしょうか？

また、xstartupファイルは、先輩が提示してくださったサイトを参考に作成しました。

ログ

xstartupファイルを作成

$ cd ~/.vnc
$ vim xstartup

xstartupファイル内容

#!/bin/sh

vinoをインストール

$ sudo apt install vino

xrdpをインストール

jetsonnano@jetsonnano-desktop:~$ sudo apt install xrdp

org.gnome.Vino.gschemaを編集

jetsonnano@jetsonnano-desktop:~$ sudo vi /usr/share/glib-2.0/schemas/org.gnome.Vino.gschema.xml

編集した部分(最下部に追加)

    <key name='enabled' type='b'>

glib-compile-schemasコマンドを使用してGnomeスキーマをコンパイル

VNC接続の暗号化を無効

jetsonnano@jetsonnano-desktop:~$ gsettings set org.gnome.Vino require-encryption false

https://github.com/masuko-shingo/jetson-nano/issues/6#issuecomment-914057197 の参考にしているURLの１つ目を見たところ，GUIがgnomeで無いと思います．よって，gnomeデスクトップがインストールされておらず，背景のみしか表示されないなどが起きていると考えられます．

ubuntu 20.04や18.04のデフォルトのデスクトップはgnomeですが，16.04のデフォルトはunityです．そのため，gnomeデスクトップ環境だと考えてコメントしましたが，jetsonがunityを使用している場合はgnomeと設定方法が異なります．

現在，gnomeで設定してしまっているようなので，gnomeデスクトップをインストールして試してみてもいいかもしれません． gnomeデスクトップを直接指定してaptでインストールする場合は以下の感じだったと思います．

sudo apt install ubuntu-gnome-desktop

デスクトップ環境の切り替えについて https://www.howtogeek.com/193129/how-to-install-and-use-another-desktop-environment-on-linux/

最後に，unityデスクトップでvncの環境を構築するのは，環境依存の部分が多く難しいかもしれないので， xfce4のデスクトップ環境でvnc serverを立てるという手もあります． https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-ubuntu-18-04

返答が遅れてしまいました。申し訳ありません。ログに抜けがありました。 https://github.com/masuko-shingo/jetson-nano/issues/6#issuecomment-914057197 の、「xstartupファイルを作成」後にubuntu-gnome-desktopをインストールしていました。基本的なことや、vncserverの使い方を間違えている可能性が高いのですが、接続ができませんでした。以下ログ ubuntu-gnome-desktopをインストール

接続を試す

jetsonnano@jetsonnano-desktop:~$ vncserver -list

TigerVNC server sessions:

X DISPLAY # PROCESS ID
:5      12678
jetsonnano@jetsonnano-desktop:~$ vncserver :5

単純にvncの接続方法が間違っているのかなと思うのですが、よくわからないという状況になっています。もう少し自分でも試行錯誤してみます。ご指摘、アドバイスお願い致します。

こちら本質ではないところで詰まって動けなくなっていると思います．大学に来て林原でも構いませんが，分かる方に直接聞いたほうが早いと思います．（林原はSIが終了するまではあまり時間を取れないかもしれませんが．．．）
