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
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:
sudo aptitude hold 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 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 }
Hardy
- 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 -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 }
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.
Errors
