Public bug reported:
Binary package hint: gdm
Problem occurs on headless server (no screen, no keyboard) which I have
just upgraded from 8.04 LTS to 10.04 LTS. I believe the problem appeared
after the upgrade. It may be related to 433928 and 578013.
The first VNC connection from a remote system works correctly. After a
normal logout from this first server session (which closes the remote
vncviewer window), subsequent VNC connection attempts fail with the
ubiquitous read: Connection reset by peer (104) message.
Restarting gdm allows connections to be made again.
The following syslog sequence shows the messages from the sequence:
1. failed connection attempt
2. restart gdm
3. successful connection attempt

My current workround is *not* to logout but close the remote vncviewer
process. The Xvnc session on the server then continues and I reuse it on
subsequent connections.
