What should I do if I get the message Could not start Xvnc after installing vnc on CentOS?

[root@localhost media]# service vncserver start

Starting VNC server: 1:root

WARNING: The first attempt to start Xvnc failed, possibly because of the font

catalog is not properly configured. Attempting to determine an appropriate

font path for this system and restart Xvnc using that font path. . .

Could not start Xvnc.

You need to add 3 packages to solve this problem

yum install pixman pixman-devel libXfont

The above is an introduction to the solution to the problem of Could not start Xvnc when installing vnc on CentOS. It is mainly caused by the lack of three packages. It can be solved by simply adding them again.
