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.

Can I setup VNC to run as a deamon so that I could simply get the login windows with a vnc viewer?
well, I couldn’t find an answer to getting remote access into the system without having a logged in user with VNC.
Instead, I use Free NX Server. Easy to set up, free version… works great.

I have a doubt regarding this..When i try to connect it shows unable to connect host.no route to host(113)
Why does this happen?? Can you suggest me a solution?
Thank you
Weird. I set everything up exactly like the way this guide says and I still can’t get connected.
Failed to connect to server “Ip Address”
@Brett
What settings do you use in NX client to make it work?
I just installed using the instructions on the website. Since we’re talking about Ubuntu,I grabbed the DEB installers for Client and Server.
I already had SSHD installed and running, and port 22 forwarded through my firewall.
Its a little wierd that you need the ‘client’ installed to run a ’server’… but whatever, it works nicely. I installed the client first, then the server. I dont remember any special settings.

Hi There,
I have set up the remote desktop option and I can remotely connect. But after the connection, I only get the initial reflection to display :0
All reflection due to the remote user interaction does not come accross to the remote viewer VNC screen, unless its being controlled locally.
The remote user is able to input via mouse and keyboard, but unable to see this input.
I have tried various viewers (All running on XP)
Could it be due to graphic card issue ( I have NVIDIA EN9400) ALl comments and responses are welcome.
Hi. I have the same problem as Bobby. One should think that to press F8 and click update screen would fix the problem, but it doesn’t.
I’m experiencing the same problem as Bobby. I’d love to know what the problem is…
It turns out disabling visual effects allows it to work properly.
nice info, nice to try
:>
My remote computer is running jaunty as well as the local machine. I am having the same issue that Bobby describes.
Lindsay’s solution works!
On the remote machine (the one you are remoting to);
System->Preferences->Appearance
“Visual effects” tab, select None.
after a short pause (probably because i’m wireless) the local screen begins to update.
