我是靠谱客的博主生动雪碧，最近开发中收集的这篇文章主要介绍【无标题】一、安装二、问题解决三、美化四、启动管理，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

一、安装

# 安装 apt-add-repository

sudo apt install software-properties-common

# 安装 xfce 4.14

sudo add-apt-repository ppa:xubuntu-dev/staging
sudo apt-get update
sudo apt-get install xfce4

#运行 xfce 4.14

startxfce4

# 卸载

sudo apt install ppa-purge
sudo ppa-purge ppa:xubuntu-dev/staging

二、问题解决

2.1普通用户无法登陆，查看日志

sudo vim ~/.local/share/xorg/Xorg.0.log

日志如下：

发现有一句错误

 parse_vt_settings: Cannot open /dev/tty0 (Permission denied)

tty0无权限，查看tty0设备权限和所属用户组

ls -l /dev/tty0

crw--w---- 1 root tty 4, 0 11月 26 17:26 /dev/tty0

c表示字符设备文件，后面三个权限表示分别表示创建者拥有权限，创建者组拥有权限，其他用户拥有权限，root表示创建者和创建者所属组。

查看用户user6的所属用户组

groups user6

user6 : user6 adm dialout cdrom sudo dip plugdev lpadmin sambashare

把user6添加到tty用户组

sudo usermod -a -G tty user6

再startxfce4启动，不再报tty0无权限。

2.2 tty0错误解决后，报下面错误：

Cannot open virtual console2(Permission denied)

需要下面操作

sudo apt-get install xserver-xorg-legacy

进入/etc/X11/Xwrapper.config

sudo vim /etc/X11/Xwrapper.config

添加下面内容

allowed_users=anybody
needs_root_rights=yes

添加后，可顺利进入xfce界面
在这里插入图片描述

2.3 在xfce界面中，右键打开终端无反应

按照网上的说法，在Application-settings-Preferred Application-Utilitles中选择xfce Terminal即可，刚打开的时候，我的下拉菜单里是没有这个选项的
在这里插入图片描述

推出图形界面，使用终端模式，输入下列指令，安装xfce4-terminal

sudo apt install xfce4-terminal

安装完成后，再进入图形界面，设置那里就有Xfce Terminal选项了，勾选后，终端就可以用了。

三、美化

GTK主题：控制窗口内容外观
窗口标题栏主题：也叫做xfwm4主题
图标主题
字体
背景图片
sudo tar xvf Vibrancy-Colors-2-5a-GTK-Icon-Theme.tar.gz --directory /usr/share/icons/

参考：

四、启动管理

因为安装xfce4之前卸载了登陆管理器，因此一开机，程序进入的是终端模式，必须再终端模式中输入startxrce4命令才能启动xfce4，使用下面指令安装登陆管理器lightdm

sudo apt-get install lightdm

安装lightdm后重启，进入用户登录界面，输入正确密码无法进入界面。

放弃lightdm登录管理器，安装gdm3登录管理器

sudo apt-get install gdm3

安装完成后将登录管理器切换为gdm3

sudo dpkg-reconfigure gdm3

使用gdm3可成功登录xfce4.

遗留问题：

后来将图形管理器切回lightdm后，依然可以成功进入xfce4,，甚至使用

sudo apt-get purge gdm3

完全清除gdm3后，依然可以正常进入桌面，神奇。
