HOWTO: Set up VNC server with resumable sessions

[dansued]

are you behind a firewall? do you have the right port specified?

usually socket errors occur when ports don't match up or are being blocked.

both computers are behind the same router, so the firewall settings shouldn't matter right?

my Xvnc conf is this,

service Xvnc
{
        type = UNLISTED
        disable = no
        socket_type = stream
        protocol = tcp
        wait = yes
        user = root
        server = /usr/bin/Xvnc
        server_args = -inetd :1 -query localhost -geometry 1024x768 -depth 16 -once -fp /usr/share/X11/fonts/misc -DisconnectClients=0 -NeverShared passwordFile=/root/.vncpasswd
        port = 5901

}

whether I connect by using :1 or :5901, I get the same socket error.

Should be ip address:1. example 192.168.1.9:1

Check your fonts path. Unless you're using an old, old version of Ubuntu, it needs fixing. I also don't see the XFIXES statement... See http://ubuntuforums.org/showpost.php...&postcount=458

am I able to make these changes in the console? I only have ssh access to this box.

Make these changes while logged into gnome:

• Go to System -> Administration -> Login Window (General tab) and uncheck "Disable multiple logins for a single user."
• Now go to the Remote tab. Change Style: to "Same as Local"
• Still on the Remote tab, click "Configure XDMCP," then uncheck "Honor indirect requests."

I don't know of a way to make the gnome changes at the console, so that could be a problem. But I'm not a super expert at this. I have always had access to make the gnome changes.

You can make changes to the Xvnc file at the command line.

Hi, Lovely HOWTO thanks...got it working...mostly.

I seem to run into a similar problem quite often.

I logged in yesterday (over the internet) and got the gdm login screen, logged in, great! full control on display:1. I could log out (using the button for logging out inthe remote window) and log back in later. or I could lock the screen and close the vncviewer.

But sometimes (well quite often) something seems to get upset and I can't get the viewer to open up again. I try the viewer, get prompted for a vnc password, but then get an error:

The connection closed unexpectedly.

And nothing I do now seems to let me get back...

So I tried the following:

jonrserv@jcrserver2:~$ vnc4server :1
A VNC server is already running as :1
jonrserv@jcrserver2:~$ sudo /etc/init.d/xinetd stop
[sudo] password for jonrserv:
 * Stopping internet superserver xinetd                                                      [ OK ]
jonrserv@jcrserver2:~$ sudo killall Xvnc
Xvnc: no process killed
jonrserv@jcrserver2:~$ sudo /etc/init.d/xinetd start
 * Starting internet superserver xinetd                                                      [ OK ]

thinking, this would kill the vnc session, starting afresh and I could log in...but it makes no difference. The only way I have solved this is by rebooting my server, but obviously this is not a nice option.

Question is basically, why is it doing it and how do I rectify it when it happens? How do I kill it off so its like the first time I am trying to log in?

Hope you can help!

Hello, after following the instructions to get vnc going in the beginning of this post, I was able to get it going....at least, mostly.

When i log in, all i see is a background of black and white tiny criss cross lines. I can't right click the desktop, and there is no taskbar or Apps menu of any sort.

What am I missing here?

-Thanks

This is a common problem, but it usually is because part of the install process wasn't done properly. Please review the following post and make sure you've done everything in it exactly as described.

Hello, i did exactly as instructed in your post, then rebooted, but it's still exactly the same. What else could it be?

-Thanks for any assistance
