By default ubuntu will come with vino-server so it is very easy to configure to enable remote desktop sharing in your ubuntu machine.If you want to access ubuntu machine remotely you need to login in to your ubuntu system.
Important note :-
Remote Desktop will only work if there’s a GNOME login session.Leaving your computer with an unattended GNOME login session is not secure and not recommended.

Everything went as written except where I enter the IP address of the host I’m trying to access.
In your example you used:
vncviewer -fullscreen xxx.xxx.xxx.xxx:0
But I had to use:
vncviewer -fullscreen xxx.xxx.xxx.xxx:1
instead.
It may not be obvious to some - substitute the IP # of the machine you seek to access for the “xxx.xxx.xxx.xxx” part.
Also, Ubuntu has a graphical client available from the menu: Applications->Internet->Terminal Server Client.
HTH.

I don’t know what is wrong with my setup, but if I turn this on and use it for any length of time (seems an hour minimum) vino-server seems eat up all my RAM and swap file and pretty much stall my machine. I’ve not done anything more custom than what was described here; if you experience the same things you’ll either need to restart or kill the vino-server process.

I’ve enabled Remote Desktop, enabled the connection and security and installed Chicken of the VNC on my Powerbook, but when I try to connect (via my internal network, 192.168.x.xxx) I get a spinning wheel until it times out. Trying a bad address causes an immediate “Server not found,” so it seems to know there’s a machine out there, but it can’t quite start. Any ideas? Filled with bafflement, am I.
Thanks.

Is there a way of remote desktop that include login (ie, with no open session)?
