Setup

Common

  • Enable XDMCP:
    • For kdm, edit /etc/kde3/kdm/kdmrc and change Xdmcp section to:
Enable=true
    • For gdm, edit /etc/gdm/gdm.conf and change xdmcp section to:
Enable=true
  • Add the following lines to /etc/services:
vnc_1024x768             5901/tcp            # VNC (1024x768)
vnc_1280x1024            5902/tcp            # VNC (1280x1024)
vnc_1920x1200            5903/tcp            # VNC (1920x1200)
  • 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:
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
}

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
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
}

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

Errors

Couldn't open RGB_DB '/usr/lib/X11/rgb'

sudo ln -s /etc/X11/rgb.txt /usr/lib/X11/rgb.txt
