先附上之前的討論「Vnc server and Ubuntu 16.04」。

可以用關鍵字「ubuntu vnc server」查詢,應該就可以查到該討論提到的「參考連結

或是用關鍵字「ubuntu vnc server 18.04」查詢,可以找到下面參考連結


* https://help.ubuntu.com/community/VNC/Servers
* https://help.ubuntu.com/community/VNC
* https://help.ubuntu.com/community/VNC/Clients

或是也可以開啟「Terminal」,執行下面指令,來找尋

可以執行下面指令找尋


$ apt-cache search vnc

Description-en: Virtual network computing server software
 VNC stands for Virtual Network Computing. It is, in essence, a remote
 display system which allows you to view a computing `desktop' environment
 not only on the machine where it is running, but from anywhere on the
 Internet and from a wide variety of machine architectures.
 .
 This package provides a vncserver to which X clients can connect and the
 server generates a display that can be viewed with a vncviewer.
 .
 It contains an X server connector so clients can connect to your local X
 desktop directly.
 .
 Note: This server does not need a display. You need a vncviewer to see
 something. This viewer may also be on a computer running other operating
 systems.

或是執行下面指令


$ apt-cache showsrc vnc4server | grep '^Binary:' -B 2



顯示

可以了解到,
關於「vnc4server」和「xvnc4viewer」這兩個「Binary Package」,
是來自於「vnc4」這個「Source Package」。


剛剛上面有執行過「apt-cache show vnc4server」。

Description-en: Virtual network computing client software for X
 VNC stands for Virtual Network Computing. It is, in essence, a remote
 display system which allows you to view a computing `desktop' environment
 not only on the machine where it is running, but from anywhere on the
 Internet and from a wide variety of machine architectures.
 .
 It is implemented in a client/server model. This package provides a vncclient
 for X, with this you can connect to a vncserver somewhere in the network
 and display its content in a window. There are vncservers available for other
 operating systems.

================================================================================

上面的模式,也可以用來探索「tightvncserver」。

執行下面指令


$ apt-cache showsrc tightvncserver | grep '^Binary:' -B 2



顯示


Package: tightvnc
Format: 3.0 (quilt)
Binary: tightvncserver, xtightvncviewer



可以了解到,
關於「tightvncserver」和「xtightvncviewer」這兩個「Binary Package」,
是來自於「tightvnc」這個「Source Package」。


執行


$apt-cache show tightvncserver



執行


$apt-cache show xtightvncviewer



或是執行下面指令,同時觀看


$ apt-cache show tightvncserver xtightvncviewer



================================================================================

執行


$ apt-cache showsrc tigervnc-standalone-server | grep '^Binary:' -B 2



顯示


Package: tigervnc
Format: 3.0 (quilt)
Binary: tigervnc-common, tigervnc-scraping-server, tigervnc-standalone-server, tigervnc-xorg-extension, tigervnc-viewer



================================================================================

更多的套件探索討論案例,紀錄在「[索引] 套件操作實務」。

附上之前的另一篇討論「#4 回覆: VNC 如何開機自動運行

================================================================================

## 套件整理

* tigervnc-standalone-server
* tigervnc-viewer
安裝指令: sudo apt install tigervnc-standalone-server tigervnc-viewer
移除指令: sudo apt purge tigervnc-standalone-server tigervnc-viewer

* vnc4server
* xvnc4viewer
安裝指令: sudo apt install vnc4server xvnc4viewer
移除指令: sudo apt purge vnc4server xvnc4viewer

* tightvncserver
* xtightvncviewer
安裝指令: sudo apt install tightvncserver xtightvncviewer
移除指令: sudo apt purge tightvncserver xtightvncviewer


下方會整理圖形界面的相關套件。

================================================================================

接下來先紀錄「指令」和「操作步驟」簡易說明

================================================================================

## 編輯 xstartup

編輯「~/.vnc/xstartup」這個檔案

執行


$ vi ~/.vnc/xstartup



填入下面的內容


#!/bin/sh

xsetroot -solid grey

#startxfce4 &
startlxqt &




加入可執行權限


$ chmod u+x ~/.vnc/xstartup



註:
我這篇測試的環境是「Ubuntu 18.04」,桌面環境使用的是「lxqt」。
關於「startlxqt」是屬於「lxqt-session」這個套件。
關於如何安裝「lxqt」,只要執行「sudo apt install lxqt」就行了,
之前有寫了一個簡單的安裝腳本,放在「GitHub」上,
一些說明,則是會放在這裡,不過還沒寫完整就是了。


================================================================================

## 設定密碼

執行


$ vncpasswd



依照提示輸入

結果會儲存在「~/.vnc/passwd」這個檔案

================================================================================

## 啟動 Server

執行下面指令,啟動 Server (可以多次執行)


$ vncserver



或是也可以指定「display number」


$ vncserver :1



或是


$ vncserver :2



================================================================================

## 啟動 Client 連到 Server

在本機執行下面指令,啟動 Client 連到 Server


$ vncviewer localhost:5901



或是執行


$ vncviewer localhost:1



或是執行


$ vncviewer localhost:2



上面「5901」是「port」,「1」和「2」是「display number」

若是在本機執行,也可以加入「-passwd ~/.vnc/passwd」,就不用輸入密碼


$ vncviewer -passwd ~/.vnc/passwd localhost:1



================================================================================

## 關閉 Server

執行下面指令,關閉 Server


$ vncserver -kill :1



或是執行


$ vncserver -kill :2



上面「:1」和「:2」是「display number」,指定要關閉那個

================================================================================

## 相關路徑

相關的檔案都放在「~/.vnc/」這個資料夾

* ~/.vnc/passwd
* ~/.vnc/xstartup

* ~/.vnc/work:1.log
* ~/.vnc/work:1.pid

* ~/.vnc/work:2.log
* ~/.vnc/work:2.pid

================================================================================

參考「ArchWiki / TigerVNC / Running vncserver to directly control the local display

執行


$ x0vncserver -display :0 -passwordfile ~/.vnc/passwd



在本機執行下面指令,畫面會無窮迴圈


$ vncviewer localhost:5900



================================================================================

若是要使用圖形界面來操作「Server」和「Client」,

以下是相關的套件整理和簡易說明。

* krfb (Server)
* krdc (Client)
安裝指令: sudo apt install krfb krdc
移除指令: sudo apt purge krfb krdc


執行


$ apt-cache search vnc | grep gnome -i



顯示


vino - VNC server for GNOME
vinagre - remote desktop client for the GNOME Desktop



* vinagre (Client)
安裝指令: sudo apt install vinagre
移除指令: sudo apt purge vinagre

若是在「Gnome Shell」的環境底下

* vino (Server)
安裝指令: sudo apt install vino
移除指令: sudo apt purge vino

裝了「vino」後,就可以在「gnome-control-center (settings)」其中一個頁簽「Sharing」,
出現一個選項「Screen Sharing」,點選,就會跳出一些新的設定視窗,在這裡做設定和啟用。

另外要讓「gnome-control-center (settings)」直接顯示頁簽「Sharing」,只要執行下面指令就行了


$ gnome-control-center sharing




在使用「krdc」或「vinagre」其中一個「Client」,來連到「vino」和「krfb」這兩個「Server」時,
要選「vnc」,然後「Port」要用「:5900」來連線,

若是使用「krdc」或「vinagre」其中一個「Client」,來連到「vncserver」,
一樣要選「vnc」,然後要「localhost:5901」或「localhost:1」或「localhost:2」,若是本機則是可以省略「localhost」。

================================================================================

以上提供參考

報告完畢
