請問有 linux 可以使用的vnc server嗎 ?

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

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

會看到很多套件。

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.

執行下面指令，過濾

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

顯示

或是執行下面指令

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

顯示

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

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
