Linux – VncServer can’t restart because of Xvnc

I don't think you can do it that way. When the user disconnects, inetd kills the servers which were spawned for that connection.

Try using NX/FreeNX instead, it can do disconnect-session persistence. It can also allegedly connect users to an already running instance on the desktop, but I've never tried that.

I think you need to set up a display manager such as GDM. When Xvnc is starting up, it tries to communicate with a running display manager via XDMCP. That's what the -query ::1 option is in your xinetd file. I've set up GDM on Hardy before, and it worked pretty well. Give this a try:

Install GDM if it's not already installed.

Edit /etc/gdm/gdm-cdd.conf:

• In the section [xdmcp], set the Enabled option to true.
• In the section [daemon], set the RemoteGreeter option to the same as the Greeter option. This isn't strictly necessary, but it's prettier.

Restart GDM.

Then try connecting again. You should see a login screen where you can enter your username and password. If that doesn't work, try changing -query ::1 to -query 127.0.0.1. It may be having trouble with IPv6.
