Comments on: Install and Configure VNC Server in CentOS 7 and RHEL 7 https://www.linuxtechi.com/install-configure-vnc-server-centos-7-rhel-7/ Tue, 15 Jun 2021 10:56:43 +0000 hourly 1 By: rajendra kumar manthan https://www.linuxtechi.com/install-configure-vnc-server-centos-7-rhel-7/#comment-23376 Tue, 15 Jun 2021 10:56:43 +0000 http://www.linuxtechi.com/?p=3276#comment-23376 Thanks for the post. I was struggling as in other links where it was mention,
$ su –
$ vncpasswd

but as in your post step-5,
#su –
#vncserver
It works for me. i.e. “vncserver” command.

my vncserver service unit file is

[vncu1@vnc-test ~]$sudo cat /etc/systemd/system/vncserver@:6.service

Connection completes with success but when I want to logout it ask for confirmation on the first attempt, with a timeout of 60 seconds to automatically disconnect.

If I wait on the 60 seconds it disconnects but when I try to reconnect again I’m not able to connect, seems like session becomes frozen.
If I don’t wait on the 60 seconds, and press the option to disconnect the session does not disconnect, and I still able to work on it but when I try to logout once again seems like the option has been disabled. If I just close the VNC viewer window and re-open the session, it comes right where I left when I closed the window.

My question is: How I can make this VNC Viewer session to behave as expected when requesting the logout from the gnome interface?

Thank you!

I created the user using vncpasswd while logged in with that user account.
