    Thank you for letting us know there is possibly an issue.

    Please double check the systemctl command was exicuted as root not a regular user.  

    If that does not help can you please post your "/etc/systemd/system/vncserver@.service" file. 

    Thanks !

    Hi,  Well this seems to be all fine.  

    Can you please let me know the version/distro you are using?

    Are you using one of the Linux Foundation images?

    Please let me know the version of vncserver and systemd you are using.

    Thanks

    Hi,  The CentOs image was downloaded from CentOs web. 

    [rks@localhost ~]$ cat /etc/centos-release

    CentOS Linux release 7.4.1708 (Core) 

    [rks@localhost ~]$ cat /proc/version

    Linux version 3.10.0-693.5.2.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) ) #1 SMP Fri Oct 20 20:32:50 UTC 2017

     

    [rks@localhost ~]$ rpm -qa | grep tigervnc-server

    Hi, I retested it on a clean installation and duplicated your issue. It is a typo in the example file. The PID specification has the wrong user name in it.

    Incorrect:

    PIDFile=/home/lee/.vnc/%H:%i.pid  

    Correct:

    PIDFile=/home/student/.vnc/%H:%i.pid

    Thank you for pointing this out, it will be corrected in the next version.
