Remote Desktop Connection Failure to Maintain Connection

Post by ASTONE » 2020/07/03 23:05:03

Hello all/anyone who has suggestion:

When I use either Windows Remote Desktop Connection of VNC to remote into my CentOS 7 Server, I can never get to the desktop. Even after successfully getting to the VNC login dialog box, upon clicking OK, the connection drops and the window closes. I've found several "solutions" on the Internet, purporting to be a step-by-step method but nothing actually comes through for me.

Sites that I've tried include:

https://www.cyberciti.biz/faq/how-to-in ... ss-server/
https://draculaservers.com/tutorials/in ... dp-centos/
https://www.linuxtechi.com/connect-wind ... 7-console/

If anyone needs specific configurations just ask, but I've generally accepted all defaults.

Thank you in advance for your help.

Remote Desktop Connection Failure to Maintain Connection - Update 1 (Stable Connection with Blank Blue Screen)

Post by ASTONE » 2020/07/04 16:29:49

To anyone following this saga,

I made the following 2 changes to move the ball forward:

1. Changed metalink=https://mirrors.fedoraproject.org/metal ... =$basearch to
metalink=http://mirrors.fedoraproject.org/metali ... =$basearch

2. Changed SELinux mode from "enforcing" to "permissive"

Then I re-installed all the repos indicated on the various websites, re-updated, re-upgraded, re-enabled and reloaded the vncserver service, and rebooted.

Result: I can now log into a VNC session without having it disconnect instantly and close. However, all I get is a blank, blue screen.

I refollowed instructions on the web sites listed above. There is controversy about the PID line in the server@.service file. That should probably be sorted out by "experts". I doubt if if that is the source of my problem because the problem exists both with and without the line.

Specific Question:

Server with GUI, GNOME Desktop and Graphical Administration Tools all show up as Available but never make the "Installated groups:" list. Anyone know why this is, or if this is related to my problem? I've recently installed MATE to see if that solves my problem. My next post will state whether or not that worked.

yum grouplist

I do plan to fully document my process if I can get this working, so that the community will have a good source to go to, but right now, I'm not finding solutions or consistency in the ethersphere. I really could use advice from an experienced expert in this area.
