Re: Remote login

[Guy Rouillier <guyr-ml1 burntmail com>]

Sorry, I did not see the original email.  I'm top-posting because most 
of what I have to say relates to the OP.  I've used vnc successfully 
numerous times, but not in quite awhile; in a work environment simple 
ssh terminals are used most often, and at home I've switched to running VMs.

First off, from the original post, I'm not sure that the server has been 
properly set up to run X (and hence Gnome.)  "could not find XKB 
extension": XKB is the keyboard and is required in any practical 
configuration.

Have you ever connected to a graphical UI directly on this box to verify 
that it is set up to run a GUI?

Next, I've usually set /etc/vncserver (as root) to automatically start 
up the required user sessions.  You appear to be running vncserver as a 
regular user.  I suppose that works but I have no experience running it 
that way.

Finally, if the server is properly configured and you want to run a GUI, 
vnc is the right way to go in my opinion.  Remote X (cygwin) sends 
individual windowing commands over the wire and will hence be 
considerably slower than vnc.

The proper way to initialize vnc is to log in via an ssh terminal to 
start your GUI session.  Then you log out and back in via vnc, which 
should attach directly to your GUI session.
