Setting up VNC server with resumable sessions in Kubuntu
Monday, November 3, 2008

This article is intended to help others to setup VNC server in Kubuntu 8.04, and is totally based on this discussion in ubuntuforums.org, please read it if you run into troubles or would like to learn more advanced configurations.


Using the VNC service provided in Kubuntu is easy. But the drawback is that you have to login first, and share the desktop with the one sitting in front of the computer too. To get a better experience in using VNC, such as background user login and resumable sessions, vnc4server should be used instead of Krfb desktop sharing.

Install the server package

Run in console:

sudo apt-get install vnc4server xinetd xvnc4viewer

Enable XDMCP in KDE

Run in console:

sudo kate /etc/kde3/kdm/kdmrc

Then find and edit the section [Xdmcp] as the following:

[Xdmcp]
Enable=true
Port=177
Xaccess=/etc/kde3/kdm/Xaccess
Willing=/etc/kde3/kdm/Xwilling

Run in console:

sudo kate /etc/kde3/kdm/Xaccess

Then find and remove the comments as seen in the following lines:

*                                       #any host can get a login window

*               CHOOSER BROADCAST       #any indirect host can get a chooser

Reboot the computer when finished.


Set the VNC password

Run in console:

sudo vncpasswd /root/.vncpasswd

Then enter the password for connecting to this server.


Add the server to XINETD

Run in console:

sudo kate /etc/xinetd.d/Xvnc

Then enter the content as below:

service Xvnc
{
        type = UNLISTED
        disable = no
        socket_type = stream
        protocol = tcp
        wait = yes
        user = root
        server = /usr/bin/vnc4server
        server_args = -inetd :1 -query localhost -geometry 1024x768 -depth 16 -once -fp /usr/share/X11/fonts/misc -DisconnectClients=0 -NeverShared passwordFile=/root/.vncpasswd -extension XFIXES
        port = 5901
}

Create a link for the font

Run in console:

sudo ln -s /usr/share/fonts/X11 /usr/share/X11/fonts

Reboot.


Test

It should work now. To test the server, run the following in console:

vncviewer localhost:1

If it prompts you to input password, it should be done now!
