Xmanager远程连接CentOS7

原文博客： https://blog.youkuaiyun.com/name_kongkong/article/details/53261626

从Xmanger官网博客得知： 
“Gnome in CentOS 7 tries to use local hardware acceleration and this becomes a problem when trying to connect remotely using XDMCP. To avoid this problem, you have to use an alternative display manager (other than ‘gdm’) and desktop environment.” 
“This guide explains how you can change the display manager to lightdm from gdm and desktop environment from Gnome to Xfce.” 
这就是使用Xfce而不用gdm的原因（仅限CentOS7），嗯，不懂的可以百度一下。

安装epel源

yum install -y epel-release

 

安装lightdm和xfce

yum install -y lightdm 
yum groupinstall -y xfce

 

这个下的有点慢 

修改配置文件

vim /etc/lightdm/lightdm.conf
...
[XDMCPServer]
enabled=true
port=177
...

 

将Display Manager切换为lightdm

systemctl disable gdm && systemctl enable lightdm

 

启动lightdm

systemctl start lightdm

 

关闭防火墙

systemctl stop firewalld.service

 

登录

打开Xmanger客户端，选择XDMCP并输入服务器的ip，回车运行即可。 
 
输入账号密码 
 
然后就出现下图：（如果正常跳过这步） 
 
这是因为刚开始安装的是Gnome，所以系统默认使用它，现在要改成Xfce，最简单的方法就是把xfce.desktopz之外的文件都干掉。

cd /usr/share/xsessions/
mkdir bak
mv gnome* bak
systemctl restart lightdm   

 

重新连接

一切正常操作之后就成功连接了。然后就可以快速便捷的工作了。
