Ubuntu 22 安装VNC远程图形界面（GNOME）

0.更新软件源

bash 复制代码

$ sudo apt update

1.安装VNC

bash 复制代码

$ sudo apt install tightvncserver

2.安装GNOME

bash 复制代码

$ sudo apt install -y gnome-panel gnome-settings-daemon metacity nautilus gnome-terminal ubuntu-desktop

3. 安装支持VNC与Windows之间复制粘贴

bash 复制代码

$ sudo apt install xclip autocutsel

4.VNC配置

4.1 首次运行设置密码

bash 复制代码

$ vncserver

4.2 修改配置文件

bash 复制代码

$ vi ~/.vnc/xstartup

直接复制如下内容，覆盖原文件内容

bash 复制代码

$ cat ~/.vnc/xstartup
#!/bin/sh

xsetroot -solid grey
autocutsel -fork

XAUTHORITY=$HOME/.Xauthority
export XAUTHORITY

unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
export XKL_XMODMAP_DISABLE=1
export XDG_CURRENT_DESKTOP="GNOME-Flashback:GNOME"
export XDG_MENU_PREFIX="gnome-flashback-"
export QT_STYLE_OVERRIDE=""
export FONTCONFIG_PATH=/etc/fonts
export FONTCONFIG_FILE=/etc/fonts/fonts.conf


gnome-session --session=gnome-flashback-metacity --disable-acceleration-check

4.3 添加启动关闭脚本

或者直接直接运行启动关闭命令

bash 复制代码

$ cat ~/vncserver_start.sh
vncserver -geometry 1920x1080 :1

$ cat ~/vncserver_stop.sh
vncserver -kill :1

5.VNC Viewer访问

下载并安装VNCViewer:
Download VNC Viewer - free - latest version

VNC Viewer访问IP:5901

6.常见问题解决

6.1 VNC 与 Windows不能自由复制粘贴

解决办法：安装上述 3 的软件包，并增加配置autocutsel -fork到xstartup

6.2 VNC中不能打开firefox,chrome等图形软件

命令打开firefox报错

bash 复制代码

$ firefox&
client is not authorized to connect server. Error cannot open display: :1

图形打开chrome也报错：

bash 复制代码

$ tail -f ~/.vnc/test:1.log

解决办法：在启动vncserver之前，加上环境变量

bash 复制代码

$ XAUTHORITY=$HOME/.Xauthority
$ export XAUTHORITY

$ env | grep XAUTHORITY
XAUTHORITY=/home/xxx/.Xauthority

也可以直接命令行执行，或者加到~/.bashrc中
