Raspberry Pi per VNC fernsteuern: Desktopzugriff unter Windows leicht gemacht

Wenn du deinen Raspberry Pi komfortabel mit Maus und Tastatur bedienen möchtest, brauchst du mehr als nur den Zugriff über das Terminal. Zwar ist das Tool PuTTY ideal, um per SSH auf die Kommandozeile des Raspberry Pi zuzugreifen – doch wer grafische Anwendungen oder die Desktopoberfläche nutzen will, stößt hier schnell an Grenzen. Terminal-Tools erlauben nämlich keinen Zugriff auf Fenstertools oder grafische Benutzeroberflächen. https://youtu.be/mc8qa8dutNk In diesem Beitrag zeige ich dir Schritt für Schritt, wie du VNC auf deinem Raspberry Pi einrichtest und von einem Windows-PC aus eine Verbindung zur grafischen Oberfläche herstellst. Damit kannst du den Pi ganz bequem fernsteuern, als säßest du direkt davor – inklusive Desktop, Maus und Tastatur. Besonders ab dem Raspberry Pi 4B, auf dem sich die Desktop-Version von Raspberry Pi OS flüssig nutzen lässt, wird diese Methode richtig komfortabel.

Was heißt VNC?

VNC steht für Virtual Network Computing und ermöglicht die Fernsteuerung eines Computers über ein Netzwerk – inklusive grafischer Benutzeroberfläche. Anders als bei einem reinen SSH-Zugriff (z. B. über PuTTY), bei dem man nur die Kommandozeile sieht, kannst du mit VNC den kompletten Desktop deines Raspberry Pi auf einem anderen Gerät anzeigen lassen. Maus- und Tastatureingaben werden dabei in Echtzeit übertragen. VNC ist ideal, wenn du Anwendungen mit Fenstern und grafischen Elementen nutzen möchtest – etwa einen Webbrowser, ein Konfigurationstool oder die grafische Entwicklungsumgebung auf dem Raspberry Pi.

VNC auf dem Raspberry Pi aktivieren

Bevor du dich per VNC mit dem Raspberry Pi verbinden kannst, muss die Funktion zunächst aktiviert werden. Das lässt sich auf zwei Arten erledigen – je nachdem, ob du bereits Zugriff auf die grafische Oberfläche des Pi hast oder lieber über die Kommandozeile arbeitest: Methode 1: Aktivierung über die grafische Oberfläche Wenn du einen Monitor, Maus und Tastatur direkt am Raspberry Pi angeschlossen hast, kannst du VNC ganz bequem über das Tool "Raspberry Pi Configuration" aktivieren. Dort findest du die Option unter dem Reiter "Interfaces", wo du den VNC-Server mit einem Klick einschalten kannst.

öffnen der Konfiguration über das Startmenü - Step1

aktivieren des Schalters VNC in der Konfiguration - Step 2 Methode 2: Aktivierung über die Kommandozeile Alternativ lässt sich VNC auch per Terminal aktivieren – z. B. über eine SSH-Verbindung mit PuTTY. Gib dazu einfach folgenden Befehl ein: sudo raspi-config

Die IP-Adresse des Raspberry Pi herausfinden

Damit du dich per VNC mit deinem Raspberry Pi verbinden kannst, musst du seine IP-Adresse im Heimnetzwerk kennen. Es gibt mehrere Möglichkeiten, diese zu ermitteln: - Über den Router: In der Geräte- oder Netzwerkübersicht deines Routers (z. B. Fritz!Box) findest du alle verbundenen Geräte samt IP-Adressen.

- Über die grafische Oberfläche: Bewege deine Maus über das Netzwerksymbol oben rechts neben der Uhr auf dem Desktop.

- Über das Terminal: Der schnellste Weg – besonders, wenn du direkt am Pi arbeitest oder per SSH verbunden bist – ist der Befehl: bashKopierenBearbeitenifconfig In der Ausgabe findest du unter dem Abschnitt wlan0 (WLAN) oder eth0 (LAN) die Zeile inet, z. B.: inet 192.168.178.59 – das ist deine IP-Adresse im Heimnetz.

Ich persönlich finde den Weg über ifconfig am einfachsten und zuverlässigsten.

VNC-Verbindung unter Windows 11 mit RealVNC Viewer herstellen

Um vom Windows-PC aus auf die grafische Oberfläche deines Raspberry Pi zuzugreifen, benötigst du einen VNC-Client. Eine der bekanntesten Lösungen ist der RealVNC Viewer, der einfach zu bedienen ist und gut mit Raspberry Pi OS harmoniert. Schritt 1: RealVNC Viewer herunterladen Lade dir den RealVNC Viewer über die offizielle Webseite herunter: 👉 https://www.realvnc.com/de/viewer/ ⚠️ Wichtig: Der RealVNC Viewer ist in der aktuellen Version nur als 14-tägige Testversion verfügbar. Danach ist eine kostenpflichtige Lizenz erforderlich, um alle Funktionen weiterhin nutzen zu können. Schritt 2: RealVNC Viewer installieren Nach dem Download führst du die Installationsdatei aus und folgst den Anweisungen. Die Installation dauert nur wenige Sekunden. Schritt 3: Verbindung zum Raspberry Pi herstellen - Öffne den RealVNC Viewer. - Gib in das Eingabefeld (1) oben die IP-Adresse deines Raspberry Pi ein (z. B. 192.168.178.59) und bestätige mit Enter. - Beim ersten Verbindungsaufbau erscheint ein Sicherheitsdialog – diesen kannst du bestätigen. - Melde dich mit den Zugangsdaten deines Raspberry Pi an (Standard: Benutzername (2) pi, Passwort (3) raspberry, sofern nicht geändert). - Nach dem Login (4) erscheint die Desktopoberfläche des Raspberry Pi in einem Fenster – fertig!

Verbindung erfolgreich hergestellt

Sobald die Verbindung steht, öffnet sich die Desktopoberfläche deines Raspberry Pi in einem neuen Fenster auf deinem Windows-PC. Du kannst dich nun ganz normal mit der Maus und Tastatur bewegen und den Pi bedienen, als würdest du direkt davor sitzen – inklusive aller grafischen Anwendungen und Tools.

In meinem Fall habe ich den Raspberry Pi über ein LAN-Kabel direkt mit dem Router verbunden, was eine deutlich stabilere und schnellere Verbindung ermöglicht als über WLAN. Gerade bei der Fernsteuerung mit VNC sorgt das für ein flüssigeres Nutzererlebnis ohne Verzögerungen oder Verbindungsabbrüche. Read the full article

CentOS - Setup and Configure VNC Server - How To

In this post we'll see how to setup and configure a VNC Server on a Linux CentOS 7.x server machine to allow remote connections from any VNC client - such as TightVNC, RealVNC and the likes. More specifically, we'll do that using the tigervnc-server software, a free tool that allows to do just that. Before proceeding, let's briefly recap what VNC is about.

Introduction

The acronym VNC stands for Virtual Network Computing and is a server-client protocol that allows a client machine (running a VNC client) to connect to and control a remote computer (powered by a VNC server). The software was originally developed by the Olivetti & Oracle Research Lab in Cambridge, UK as an open-source initiative and its source code is still available, as of today,  under the GNU General Public License. Depending on the VNC server software, the client will connect to the currently active runtime desktop (such as some "modern" softwares like Teamviewer or AnyDesk) or to a stand-alone virtual desktop, just like the Windows Remote Desktop RDP protocol: the latter behaviour is arguably more powerful and secure, especially if we need to control a server machine, because each session will be a unique environment configured with the permissions and grants of the connected user. That's why we're chosing TigerVNC, which works exactly like that by starting parallel sessions of the machine desktop environment (Gnome, KDE or other GUI) on the connecting client VNC desktop: this basically means that a standalone virtual desktop will be created for each separate connection - which is precisely what we want.

Installing TigerVNC

Now that we know what are we talking about, let's see how we can setup and configure TigerVNC under our CentOS environment. The first thing to do is to install the tigervnc-server software package by opening a terminal session and issuing the following command with root privileges: Right after that, you should create a dedicated VNC user to connect with (with a dedicated password). To do that, type the following: We'll say it only once: never do that with the root user. Enabling VNC for the root user would create a serious security risk to your system that you'll generally want to avoid.  Leaving the root user out of VNC and configuring a dedicated account with limited permissions instead - like the one in the above example - is definitely a better choice. Once you created the vncuser and its login password, you also need set a VNC-unique password for that user. This can be done with the following command: (the first line can be omitted if we are actually connected with vncuser beforehand). The next thing to do is to create a VNC configuration file for the vncuser: the fastest way to do that is to copy the VNC generic template file - located in the /lib/systemd/system/ folder - and then modify it according to our need: That "1" which we put in the new filename is the display number that will be used for that specific service instance. That's important to know, because it will also determine the TCP port that our VNC server will be listening to, which is 5900 + the display number: the first one will be 5901, then 5902 and so on. Right after the copy, you need to edit the new file using vi, nano or another text editor and replace the placeholder with the name of the user created a short while ago (vncuser in our scenario). Here's how the file should look after the update (minus the long commented part at the beginning): As soon as you do that, you can reload the VNC daemon and start the vncserver @1 with the commands below: Before proceeding, it could be wise to check if the service is running by issuing the systemctl status command... ... and create the symlink to have it always executed on system startup using the following command: Another check you can do before trying to connect to our server is to take a look to the active network sockets using the ss command: if everything works properly, you should see a VNC server running and listening on port TCP 5901. Here's the command to execute... ... And this should be the result: If you can see this, it means that everything has been setup correctly.

Firewall configuration

Since our VNC service is listening to port TCP 5901, you need to be sure that such port is open and accessible by external clients: therefore, if you have a firewall installed, you should create an appropriate rule to allow VNC clients to connect. How many ports to open will depend by how many instances of VNC servers you'll going to need: in our scenario, you only made 1, therefore you only need to open the first allocated VNC port: TCP 5901, just like we said. Here's the command to open that port on firewalld: Needless to say, you can also restrict that port for specific groups, IP addresses, network cards or other simple or complex firewall rules: that's entirely to you, depending on your network environment's configuration and how much you want to be safe.

Installing a GUI

If you already have GNOME, KDE or other desktop environments installed on our system you can skip this step, otherwise you'll need to add one: the TigerVNC server will start a parallel instance of a given desktop environment for each login session, meaning that we need to have one - otherwise it won't work. GNOME If you really want the great (but heavy-weight) GNOME, type the following: Xfce If you want a lightweight alternative, we can suggest Xfce -  a free & open source desktop environment for Unix-like platforms which work perfectly with TigerVNC. Don't misunderstand us here, GNOME works fine as well, but it's quite space-and-resource-intensive: if you want to save resources on your server machine, Xfce would arguably be a better choice. To install it, type the following: Additional settings for Xfce If you've chosen to use Xfce, you'll also need to change the file to execute when the VNC session starts. To do that, edit the /home//.vnc/xstartup file and change the exec entry (usually line 4)from etc/X11/xinit/xinitrc to startxfce4, just like the following: That's about it.

Connecting with VNC Client

Now that everything  

Troubleshooting

In case your client is unable to establish a working VNC connection, you need to checkup the following: Connection issues -> Firewall configuration: if you see pop-up errors saying that the client cannot connect to the remote host, you need to check your network & firewall configuration to be sure that there aren't blocking issues that could prevent the client from connecting to server port TCP 5901. Black screen with mouse -> YUM update or GUI reinstall: if you see a black screen with the mouse pointer working, that probably means that your VNC connection is working fine but there is something that prevents Desktop Environment GUI from starting properly. The best things you can try to fix such odd behaviour are: Perform a yum update to install the newest versions of TigerVNC and the GUI itself. Be sure to watch out for any issue during the install phase that could prevent them from installing/updating properly. Uninstall and reinstall the GUI using yum remove / yum group remove and yum groupinstall again. If it still doesn't work, you might want to try out a different GUI to see if the problem persists.

Conclusion

That's about it, at least for the time being: we hope that this guide could help other System Administrators who want to connect to their servers with the VNC protocol!   Read the full article

Termux、AndronixでUbuntuをインストール

タイトルだけ読むと役に立ちそうに見えるかもしれませんが、ほぼ日記的なメモで、世間一般にはあまり役に立たない記事になっていると思います。

これまではAndroidタブレットにUserlandというアプリを使って、Debian+xfce環境をインストールしてたまに使っておりました。今はひょっとしたら改善されているのかもしれませんが、��の当時UserlandでもUbuntuをインストールして使いたかったのですが、Ubuntuをインストールしてxfceをインストールすると、themeファイルの一部が欠けてしまうのか、はたまた別の理由なのか、とにかくxfceの表示が乱れて上手くいかず、悪戦苦闘した結果、結局Ubuntuのインストールを諦めて、Debianとxfceの組み合わせで使っておりました。

ただこの環境でもxfceの動作があまり安定しておらず、例えばファイルブラウザのthunarを起動して、thunarからテキストファイルをダブルクリックしてテキストエディターを起動すると、thunarが強制終了。再度thunarを起動すると、先程起動したテキストエディターが強制終了…みたいなことが起きやすく、だんだんUserlandを使う機会が減っていきました。

Userlandで作ったLinux環境は、アプリを起動して使いたいLinux環境を選ぶだけで、Linux環境を立ち上げてVNCクライアントアプリまで自動で起動してくれるので、アプリとしては非常に使いやすいんですけれど、もっと動作が安定したUbuntu環境をAndroid上でも使いたいなぁ、と思ってググってみたところ、TermuxとAndronixというアプリのことを知り、今回試してみた次第。

Termuxアプリは色々なところで紹介されているので、詳しい使い方などは省きます。

Andronixアプリは、TermuxでUbuntuをインストールするのに必要なコマンドを生成してくれるアプリといった感じのもので、インストールしたいUbuntuやデスクトップ環境をAndronixで選んでいくと、最終的にTermuxで入力するコマンドがコピーされるので、Termux上でコマンドをペーストして実行すると、Ubuntuやxfceなどのインストールが簡単にできる、という感じ。

で、当初AndronixでUbuntuの18.04をインストールしてみたところ、aptでインストールできるFirefoxのバージョンが59という、一体いつのバージョンだよ…という状況で、多少はFirefoxのバージョンが古くても我慢する気ではいたんですが、流石に古すぎるのでUbuntu18.04は断念。なら最新に近いUbuntu 22.04ならFirefoxも最新に近いバージョンがインストールできるのでは？と思ってインストールしてみるも、xfce関連の動作や設定があまり上手くいかず、こちらも断念。結局、Ubuntu20.04とxfceという環境に落ち着きました。

ちなみに、Ubuntu20.04のaptでインストールされるFirefoxのバージョンは112と、かなり新し目でした。最初からUbuntu20.04にしとけば良かった…。

AndronixとTermuxでインストールしたUbuntu20.04+xfce環境は、UserlandのDebian+xfceと比べて非常に安定して使えます。ただ、いくつか個人的に気になる点があって、以下はそのメモです。

・fcitx-mozcが上手く動かない。

他のサイトにも書いてありましたが、インストールはちゃんと出来ているように見えるんですが、何度再インストールをしても上手くいきませんでした。通知アイコンがmozcに変わるところまではいくんですが、mozcの設定とかを選んでも起動しません。ターミナルでコマンドを打ち込んでも、エラーを表示することもなく、ただ起動しません。仕方がないので、日本語入力はfcitx-anthyを使うことにしました。こちらはちゃんと動きます。

・psコマンドが使えない

原因はさっぱり分かりませんが、procがマウントされていないとかなんとかのエラーが出ます。タスクマネージャーとかも起動はしますが、プロセス一覧などは表示されません。ただ、pgrepやpkillコマンドは使えるので、psコマンドが使えなくてもなんとかなる気はします。

・TermuxでのUbuntuの起動・終了が面倒

Termuxを起動して、bash start-ubuntu20.sh などと打ち込むとUbuntuが起動するので、さらに vncserver-start と打ち込むことで、やっとVNCクライアントアプリからUbuntu+xfceにアクセスできるようになります。

Ubuntuを終了する時は、Termuxアプリでまず vncserver-stop と打ち込んで終了するポート番号を入力してvncserverを終了、次に exit を入力してUbuntuを終了という手順が必要です。vncserverr-stopを実行しないでUbuntuを終了すると、次回Ubuntuを起動してvncserverを起動した時に、通常はポート1で起動するはずが、ポート２、ポート３…と別のポートでvncserverが起動することになって、VNCクライアントで接続するのが手間になります。

なので、うちではTermuxを起動したら、Ubuntuとvncserverを自動起動、Ubuntuを終了する際には、vncserverも自動終了するようにしてみました。

やり方は、Termuxは起動時に .bashrcファイルがあれば、それを読み込んで実行するらしいので、Termuxでテキストエディターのnanoが使えるなら nano .bashrc と打ち込んで.bashrcファイルに、bash start-ubuntu20.sh と入力して保存。これで次回からTermuxを起動するとUbuntuが自動的に起動します。

次は起動したUbuntu上の .profile を開いて、 vncserver-start を追加。これでUbuntuを起動した時に vncserver-start コマンドも自動化されます。さらに .profile の exit(){ などと書かれているところに pkill Xtigervnc とかを追加すると、UbuntuをTermux上で exit と打ち込んで終了する時に、起動中のvncserverも自動で終了してくれます。以下はうちの .profile の例。このやり方が正しいかどうかは定かではないので、やる場合は自己責任で。

#~/.profile: executed by Bourne-compatible login shells. if [ "$BASH" ]; then  if [ -f ~/.bashrc ]; then    . ~/.bashrc    vncserver-start  fi fimesg n 2> /dev/null || true exit() {        #vncserver-stop        pkill Xtigervnc        if pgrep -f tiger >/dev/null;then                unset -f exit                exit        else                pkill dbus                pkill ssh-agent                pkill gpg-agent                pkill pulseaudio                unset -f exit                exit        fi }

vncserver-stop ではなく pkill Xtigervnc にしているところがミソ。まぁ、vncserver-stop でもダメではないんですが、Ubuntu終了時に起動しているvncserverをとにかく全部終了して欲しいだけなので、うちでは pkill Xtigervnc にしています。

・VNCクライアントの反応が鈍くなる

これはTermuxと直接関係はないんですけれど、VNCクライアントでUbuntuのデスクトップを表示させている場合、しばらくなにも操作をしていないと、VNCクライアント上の描画の更新が途切れがちになったり、マウスやキーボードの操作が遅れて反映されたりします。VNCサーバー側の仕様なのか、使用しているVNCクライアントアプリの仕様なのか、Androidの仕様なのか、よく分かっていませんけれど、解決方法はあります。

Ubuntuの画面が頻繁に更新されるように、なにか動画を再生し続けていれば良いのです。動画と言っても小さなGIFアニメを再生しっぱなしにするだけで良く、なのでうちではrubyで同じGIFアニメファイルをただ延々と再生するだけのプログラムを作って、常に画面の最前面に表示するオプションをONにして、画面の端っこに表示させたりしています。xffceの上側のパネルにはデジタル時計を秒数付きで常時表示させてはいるんですが、この程度の描画の変化・更新ではダメみたいで、小さめのGIFアニメならOKという感じです。

そんなこんなで、core i5のノートPCでXubuntuを使うのと比べると、Android上のUbuntu+xfce環境の動作は若干もっさり気味ですが、これまで使っていたUserlandのDebian+xfce環境よりも全然安定していて、これならAndroid上でUbuntuを使う場合は、UserlandからTermuxに完全に乗り換えできそうです。

Ubuntu 16.04安装 GNOME3 + VNC

更新 Ubuntu 系统补丁：

sudo apt-get -y upgrade

开始：有一个更简单粗暴的办法是直接装 UBUNTU GNOME发行版，但是当我安装完UBUNTU16的时候，我真的不想重新装一遍系统。

所以就在原有基础上安装gnome3，很多人觉得用不习惯，其实桌面环境这个还是挺方便的。

sudo apt-get install gnome-shell sudo apt-get install ubuntu-gnome-desktop

值得注意的是，记得要在安装gnome-shell的时候选择那个gdm，不然开机默认还是unity

sudo apt-get install unity-tweak-tool sudo apt-get install gnome-tweak-tool

然后重启大发。搞定。

配置VNC服务器

安装VNC服务端 #sudo apt-get install vnc4server

开启VNC服务 #sudo vncserver

在此期间会要求设置VNCServer的密码，注意，最大长度为8位。 设置密码后，看到（连接VNC 用端口 1） New ‘****:1 (****)’ desktop is ****:1 (****代表主机名，注意那个：1）

关闭原桌面进程并生成新进程 sudo vncserver -kill :1

生成新的进程： sudo vncserver :1

重启服务器后，可能半天无法登录，这时，只需要等一会儿就行了

这时，登录ssh 会提示： 

这种情况，是后台以为你的服务器开了N 多个回话，攻击服务器，所以不要紧张，等一会就可以登录了。

Ubuntu 16 安装GNOME，和vncserver后只显示桌面,不显示菜单栏解决

  一般的server操作系统是不安装图形系统的，这样的话，要想打开它的图形界面可以在server端上安装vncserver软件。然后再在本地机器(windows或linux)上安装一个vnc viewer就能显示图形界面。 

最后我不得不安装另一个图形库Xfce4 $ sudo apt-get install xfce4  

安装会提示有未更新的文件，用更新的来安装： $sudo apt-get update

然后修改配置文件~/.vnc/xstartup如下：

#!/bin/sh                                                                   # Uncomment the following two lines for normal desktop:   # unset SESSION_MANAGER   # exec /etc/X11/xinit/xinitrc      [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup   [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources   xsetroot -solid grey   vncconfig -iconic &   x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &   x-window-manager &   sesion-manager & xfdesktop & xfce4-panel &    xfce4-menu-plugin &    xfsettingsd &    xfconfd &    xfwm4 &  

  然后重启vcnserver， # vncserver -kill :1 # vncserver

再在本地登录，成功！

When trying to use it in the terminal it prints outs all caps letters: for example - 123456789 ~]$ BDECA When trying to use the 10-key to enter numbers in a text editor app I just get the "ding" error sound. Also, for whatever reason the 10-key does work in the calculator app in Linux, but nothing else. Is this a bug in GNOME perhaps? Worth mentioning that the 10-key does work in Windows and macOS when connected via VNC. First, update your software sources using apt.

To overcome this, you will have to install the Light Display Manager, or lightdm. Install a virtual network computing (VNC). Unfortunately, GDM does not usually work very well with the x11vnc server. I have disabled "Mouse Keys" but this has no effect and did not resolve the issue. Install the MATE desktop environment, a lightweight GUI based on GNOME 2 available as an extra for Amazon Linux 2. This will perform a disconnect from the VNC server but anything you leavethat. These are both physical machines, but I have not yet tried actually connecting the same keyboard to the Linux machines yet since I need the VNC connection to work. To close out of VNC Viewer or Chicken of the VNC, just close the VNC window. I recently discovered that the 10-key (numeric) part of my Mac keyboard no longer works on either desktop when connected via VNC. They both are using GNOME desktop: 41.1 for Fedora, and 40.5 for Ubuntu I use VNC (RealVNC "VNC Viewer" app) on my Mac to connect to Linux desktops: Fedora 35 & Ubuntu 21. and I can connect to it using Tight vnc viewer from windows but the UI looks like But, I want to use the default desktop that ships with Ubuntu 18.

Konfiguracja VPS ( Instalowanie GUI, VNC, Chrome)

Poradnik pisany oryginalnie na serwerze discord przez moją osobę.

pominę etap wybierania hostingu, płatności.

(polecam ovh)

Rozdział 1 - Logowanie do serwera

w moim przypadku na ovh.pl mam dostęp w przeglądarce do "zdalnego pulpitu" ale opiszę sposób zrobienia tego "na około" aby ten poradnik był zgodny z każdym hostingiem

1. Uruchamiamy program putty , wpisujemy IP serwera po czym klikamy "Open" i logujemy się do systemu (dane powinny przyjść mailem, lub s�� podane w panelu Hostingu)

2. Na początek zmienimy hasło na takie które będziemy pamiętać w tym celu wpisujemy komendę

passwd

wpisujemy stare hasło po czym 2 razy nowe hasło.

Rozdział 2 - Instalacja GUI

1. uruchamiamy zestaw komend

sudo apt-get update && sudo apt-get upgrade

jeśli pojawi się okno z restartem to walimy pięścią w klawisz ENTER

2. Teraz zainstalujemy manager logowania(?) Slim

sudo apt-get install slim

jeśli wyskoczy nam pytanie Do you want to continue?

to wpisujemy Y (lub T jeśli system jest po polsku)

i klikamy ENTER

3. Pora na właściwą instalację GUI

Wpisujemy komendę

sudo apt-get install tasksel

albo

sudo apt install ubuntu-desktop

po czym uruchamiamy

sudo tasksel

zaznaczamy strzałkami i spacją "ubuntu desktop" i klikamy enter

no i w tym miejscu się zatrzymałem, potrzebuje VNC aby połączyć się z pulpitem ale zapomnialem jak go zainstalowalem dlatego tworzę poradnik aby drugim razem nie zapomnieć XD

część 2 - po roku

gnome mi nie działa na innym vps więc dalsza część poradnika będzie od nowa pod xfce

sudo apt-get update && sudo apt-get upgrade

sudo apt-get install xfce4

sudo apt-get install -y xfce4-goodies

sudo apt install tightvncserver

vncserver

wpisujemy haslo 2 razy jesli nas poprosi

vncserver -kill :1

nano ~/.vnc/xstartup

#!/bin/bash

xrdb $HOME/.Xresources

startxfce4 &

wklejamy te 3 linijki, kasujac poprzednie wpisy.

zapisujemy ctrl+O i klikamy enter

vncserver

gotowe. łączymy sie przez vncviewer IP:5901

How to Install a Desktop (GUI) on an Ubuntu Server (phoenixnap.com)

[czp356]

Ubuntu14 配置GUI + VNC 远程访问

安装gnome桌面环境（一定要先装，否则会反复失败！）

安装x－windows的基础： #sudo apt-get install x-window-system-core （部分文件不成功，用#apt-get update）

安装登录管理器 #sudo apt-get install gdm

安装Ubuntu的桌面： #sudo apt-get install ubuntu-desktop

重启之后进入系统便有GUI了

配置VNC服务器

安装VNC服务端 #sudo apt-get install vnc4server

开启VNC服务 #sudo vncserver

在此期间会要求设置VNCServer的密码，注意，最大长度为8位。 设置密码后，看到（连接VNC 用端口 1） New ‘****:1 (****)’ desktop is ****:1 (****代表主机名，注意那个：1）

关闭原桌面进程并生成新进程 sudo vncserver -kill :1

生成新的进程： sudo vncserver :1

Ubuntu 14安装vncserver后只显示桌面,不显示菜单栏解决

  一般的server操作系统是不安装图形系统的，这样的话，要想打开它的图形界面可以在server端上安装vncserver软件。然后再在本地机器(windows或linux)上安装一个vnc viewer就能显示图形界面。 

最后我不得不安装另一个图形库Xfce4 $ sudo apt-get install xfce4  

安装会提示有未更新的文件，用更新的来安装： $sudo apt-get update

然后修改配置文件~/.vnc/xstartup如下：

#!/bin/sh                                                                   # Uncomment the following two lines for normal desktop:   # unset SESSION_MANAGER   # exec /etc/X11/xinit/xinitrc      [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup   [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources   xsetroot -solid grey   vncconfig -iconic &   x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &   x-window-manager &   sesion-manager & xfdesktop & xfce4-panel &    xfce4-menu-plugin &    xfsettingsd &    xfconfd &    xfwm4 &  

  然后重启vcnserver， # vncserver -kill :1 # vncserver

再在本地登录，成功！
