I was running Xubuntu 8.04 "Hardy Heron". I configure the vnc by adding vino-server to the autostarted app. I accessing the display only via VNC, so I removed the monitor and ir worked fine.
When I upgrade to 10.04 "Lucid Lynx", I was unable to connect. I borrow back the monitor and I plug it. I was seeing nothing so I do a restart by ssh. When it restart, I was able to vnc without an issue. I removed the monitor and worked like that for a few week, but when I installed some update, I needed to restart. After the restart, the vnc is not available. When I to a ps -aux by ssh, the xserver does not seem to be running.
How could I tell xubuntu 10.04 to automatically start the xserver when no monitor is plug, just as 8.04?
