解决方案：

VMware虚拟机关闭后，把这个勾打上，然后在启动虚拟机，再次执行startx命令，成功进入桌面

二，

多个桌面是否可以同时存在？

答案是肯定的，多个桌面可以同时存在，例如GNOME和KDE是可以共存的，只是在使用桌面的时候需要指定使用哪个桌面而已。

三，

GNOME和KDE安装时的应注意事项

通常桌面不需要外部yum源，只使用操作系统ISO搭建的本地仓库，如果有依赖报错，必须手动排除掉，不能强制安装。

四，

GNOME桌面的安装：

yum groupinstall "GNOME Desktop"

KDE桌面的安装：

yum groupinstall "GNOME Desktop"

五，

桌面启动的方式

GNOME前台启动方式在centos7下是?startx?命令（如果是在xshell下面）

GNOME后台启动方式在centos7下是systemctl isolate graphical.target（如果是在xshell下面）

KDE前台启动方式：

[root@centos4 ~]# echo "exec startkde">>~/.xinitrc
[root@centos4 ~]# startx

启动后前台持续打印日志：

xauth:  file /root/.serverauth.1713 does not exist
