Thanks for the response.
It looks like the default port is set which is good :
I believe that this further confirms that 5900 is the port being used :
root@argonaut:~# dconf read /desktop/gnome/remote-access/alternative-port
root@argonaut:~# gsettings list-recursively org.gnome.Vino
org.gnome.Vino alternative-port uint16 5900
org.gnome.Vino authentication-methods ['none']
org.gnome.Vino disable-background false
org.gnome.Vino disable-xdamage false
org.gnome.Vino enabled false
org.gnome.Vino icon-visibility 'client'
org.gnome.Vino lock-screen-on-disconnect false
org.gnome.Vino mailto ''
org.gnome.Vino network-interface ''
org.gnome.Vino notify-on-connect true
org.gnome.Vino prompt-enabled true
org.gnome.Vino require-encryption false
org.gnome.Vino use-alternative-port false
org.gnome.Vino use-upnp false
org.gnome.Vino view-only false
org.gnome.Vino vnc-password 'keyring'
This coule be the problem :
vino doesn't appear to be running, even though I've gone through the gui steps to enable desktop sharing.
root@argonaut:~# netstat -nlp | grep -i vino
root@argonaut:~# ps -ef | grep -i vino
root 10734 10489 0 17:51 pts/7 00:00:00 grep -i vino
Any ideas what would be preventing this or how I might go about diagnosing why it wouldn't actually run ? error file or some verbose output ? I'll be googling as well in the meantime ..
Many Thanks for the responses !
