=== Common ===
 
 
 
* Enable XDMCP:
 
** For kdm, edit /etc/kde3/kdm/kdmrc and change Xdmcp section to:
 
<pre>
 
Enable=true
 
</pre>
 
** For gdm, edit /etc/gdm/gdm.conf and change xdmcp section to:
 
<pre>
 
Enable=true
 
</pre>
 
 
 
* Add the following lines to /etc/services:
 
<pre>
 
vnc_1024x768            5901/tcp            # VNC (1024x768)
 
vnc_1280x1024            5902/tcp            # VNC (1280x1024)
 
vnc_1920x1200            5903/tcp            # VNC (1920x1200)
 
</pre>
 
 
 
* You may wish to turn off the local X-server if you're not going to access the machine locally. To do this, comment out the line ''0=Standard device=/dev/console'' in /etc/gdm/gdm.conf
 
 
 
=== Feisty ===
 
 
 
* Install vnc4server
 
 
 
* Add the following to /etc/xinetd.d/vnc:
 
<pre>
 
service vnc_1024x768
 
{
 
        disable        = no
 
        socket_type    = stream
 
        protocol        = tcp
 
        wait            = no
 
        user            = nobody
 
        server          = /usr/bin/Xvnc
 
        server_args    = -inetd -query localhost -geometry 950x700 -depth 24 -once securitytypes=none
 
}
 
 
 
service vnc_1280x1024
 
{
 
        disable        = no
 
        socket_type    = stream
 
        protocol        = tcp
 
        wait            = no
 
        user            = nobody
 
        server          = /usr/bin/Xvnc
 
        server_args    = -inetd -query localhost -geometry 1260x960 -depth 24 -once securitytypes=none
 
}
 
 
 
service vnc_1920x1200
 
{
 
        disable        = no
 
        socket_type    = stream
 
        protocol        = tcp
 
        wait            = no
 
        user            = nobody
 
        server          = /usr/bin/Xvnc
 
        server_args    = -inetd -query localhost -geometry 1860x1120 -depth 24 -once securitytypes=none
 
}
 
</pre>
 
Note: To enable persistent sessions (which has the downside of only enabling 1 login per service), prefix '''-inetd''' with ''':'''''n'' where ''n'' is a number beginning at 1 for the first service, and counting up.
 
 
 
* Restart xinetd
 
 
 
=== Gutsy ===
 
For some reason, vnc4server doesn't play nicely with gutsy and XDMCP, so instead you need to use vncserver.
 
 
 
* Install vncserver (and make sure vnc4server is not installed)
 
 
 
* Add the following to /etc/xinetd.d/vnc. Note that for some reason Xvnc doesn't work with depths above 16
 
<pre>
 
service vnc_1024x768
 
{
 
        disable        = no
 
        socket_type    = stream
 
        protocol        = tcp
 
        wait            = no
 
        user            = nobody
 
        server          = /usr/bin/Xvnc
 
        server_args    = -inetd -query localhost -geometry 950x700 -depth 16 -once
 
}
 
 
 
service vnc_1280x1024
 
{
 
        disable        = no
 
        socket_type    = stream
 
        protocol        = tcp
 
        wait            = no
 
        user            = nobody
 
        server          = /usr/bin/Xvnc
 
        server_args    = -inetd -query localhost -geometry 1260x960 -depth 16 -once
 
}
 
 
 
service vnc_1920x1200
 
{
 
        disable        = no
 
        socket_type    = stream
 
        protocol        = tcp
 
        wait            = no
 
        user            = nobody
 
        server          = /usr/bin/Xvnc
 
        server_args    = -inetd -query localhost -geometry 1860x1120 -depth 16 -once
 
}
 
</pre>
 
Note: To enable persistent sessions (which has the downside of only enabling 1 login per service), prefix '''-inetd''' with ''':'''''n'' where ''n'' is a number beginning at 1 for the first service, and counting up (and probably remove "-once" from args).
 
 
 
* Restart xinetd
 
 
 
=== Gutsy amd64 ===
 
Even more unfortunately, vncserver coredumps on amd64 architecture, so we need to install an old version of vnc4server.
 
 
 
* Ensure neither vncserver or vnc4server are installed
 
* Install ''http://gb.archive.ubuntu.com/ubuntu/pool/universe/v/vnc4/vnc4server_4.1.1+xorg1.0.2-0ubuntu1_amd64.deb''
 
* Put vnc4server on hold to stop it being upgraded using:
 
<pre>sudo aptitude hold vnc4server</pre>
 
* * Add the following to /etc/xinetd.d/vnc:
 
<pre>
 
service vnc_1024x768
 
{
 
        disable        = no
 
        socket_type    = stream
 
        protocol        = tcp
 
        wait            = no
 
        user            = nobody
 
        server          = /usr/bin/Xvnc
 
        server_args    = -inetd -query localhost -geometry 950x700 -depth 16 -once -fp /usr/share/fonts/X11/misc securitytypes=none
 
}
 
 
 
service vnc_1280x1024
 
{
 
        disable        = no
 
        socket_type    = stream
 
        protocol        = tcp
 
        wait            = no
 
        user            = nobody
 
        server          = /usr/bin/Xvnc
 
        server_args    = -inetd -query localhost -geometry 1260x960 -depth 16 -once -fp /usr/share/fonts/X11/misc securitytypes=none
 
}
 
 
 
service vnc_1920x1200
 
{
 
        disable        = no
 
        socket_type    = stream
 
        protocol        = tcp
 
        wait            = no
 
        user            = nobody
 
        server          = /usr/bin/Xvnc
 
        server_args    = -inetd -query localhost -geometry 1860x1120 -depth 16 -once -fp /usr/share/fonts/X11/misc securitytypes=none
 
}
 
</pre>
 
 
 
 
 
=== Hardy ===
 
 
 
* Install vnc4server
 
 
 
* Add the following to /etc/xinetd.d/vnc:
 
<pre>
 
service vnc_1024x768
 
{
 
        disable        = no
 
        socket_type    = stream

        server          = /usr/bin/Xvnc
 
        server_args    = -inetd -query localhost -geometry 950x700 -depth 24 -once securitytypes=none -extension XFIXES
 
}
 
 
 
service vnc_1280x1024
 
{
 
        disable        = no
 
        socket_type    = stream
 
        protocol        = tcp
 
        wait            = no
 
        user            = nobody
 
        server          = /usr/bin/Xvnc
 
        server_args    = -inetd -query localhost -geometry 1260x960 -depth 24 -once securitytypes=none -extension XFIXES
 
}
 
 
 
service vnc_1920x1200
 
{
 
        disable        = no
 
        socket_type    = stream
 
        protocol        = tcp
 
        wait            = no
 
        user            = nobody
 
        server          = /usr/bin/Xvnc
 
        server_args    = -inetd -query localhost -geometry 1860x1120 -depth 24 -once securitytypes=none -extension XFIXES
 
}
 
</pre>
 
Note 1: This setup may also work for gutsy (ie. with the addition of "-extension XFIXES"), though I haven't tested it.
 
 
 
Note 2: To enable persistent sessions (which has the downside of only enabling 1 login per service), prefix '''-inetd''' with ''':'''''n'' where ''n'' is a number beginning at 1 for the first service, and counting up.
