About Xmanager Remote Desktop CentOS 7

GNOME Enablement in CentOS7 The local hardware acceleration function is disabled, so there will be problems when connecting to CentOS remotely through the XDMCP protocol. This has been mentioned in the blog of Xmanager official website (http://blog.netsarang.com/89/connecting-to-centos-7/), and it is recommended to use other display managers (such as lightdm, etc.) and desktop environment (xfce or kde) to circumvent this problem.

Install lightdm

# 增加epel 源
sudo yum install epel-release
sudo yum install  lightdm

Edit configuration file

sudo vim /etc/lightdm/lightdm.conf

[XDMCPServer]
enabled=true
port=177

Install xfce or kde

It is recommended to install kde, the interface is better than xfce

# kde
sudo yum groupinstall "KDE Plasma Workspaces"
# xfce
sudo yum install xfce

# 将Display Manager 切换为 lightdm
sudo systemctl disable gdm
sudo systemctl enable lightdm
sudo systemctl start lightdm
# 关闭防火墙
sudo systemctl stop firewalld.service

Xstart configuration

# xfce
/usr/bin/xfce4-session
# kde
DISPLAY=$DISPLAY; /usr/bin/startkde
