lots of problems with tigervnc server on AWS based centos 7 server

[David Brown]

Been having alot of issues getting tigervnc server to run on an amazon based centos 7 server.
Basically,



1.once I enable a new user for vnc access, I can get connected the first time to the server, every subsequent attempt just results in a black screen, even after waiting for 15 minutes

2.once I run into the above problem, every attempt to systemctl stop then start or restart the vncserver@:.. results in the following message:
[centos@ip-10-33-185-135 ~]$ sudo systemctl start vncs...@1.service
Job for vncs...@1.service failed because the control process exited with error code. See "systemctl status vncs...@1.service" and "journalctl -xe" for details.

3.this has occured after having recreated the server three times (i.e. created a new amazon instance each of thr three times).  Besides the basic Centos 7 install (this is one of amazons official
  centos 7 versions) I've only installed Gnome desktop and tigervnc-server. 

4.this last attempt I noticed that when I start a remote session, even though I have two users enabled for nvcservice, I only see a single user at the login screen of the server

5.I've used various web sites as a guide to do this install.  and having done it three time I'm pretty confident I'm not doing anything totally stupid.  Again, the initial session seems to work ok,
every subsequent remote session has all kinds of issues

I'm just about at my wits end regarding this, any help appreciated!  I do have the logs, the output from various ssh sessions if that is of any help

Sincerely,
David

Could you share those logs?

This is a very old release. Could you try the current version?
