Remote Desktop into Ubuntu 17.10 from Windows 10


I am looking for a solution that I can use to be able to remote control into my Ubuntu 17.10 from Windows 10.

I would like to be able to do this without having to change my "Display Manager". So I want to keep using the same
one that is there. Forgive me as I don't know the correct term.

Is this possible to do this? If so what are the steps.

Thanks for the responses. I have done what is suggested and I get an error saying: "The connection was refused by the computer".

I have attached some screen shots to illustrate.

Any suggestions on how to resolve?

Hi Peter,

Thanks for that. I tried your suggestion and am getting the same error.

lets suggest the firewall is active - and let us allow vnc incoming with:

sudo ufw allow 5900

please test and report ....

Hi Peter,

Same result.

I also ran the following.

How can I check the the VNC service is installed or even running?

Have I missed a step?

Here is some extra commands I ran below.

to check if vnc is up and running please try:

netstat -tulpen | grep -i 5900

there should be a line showing the server program is running at this port.

I found an andditional important thing. To avoid problems with Windows one should disable vnc encryption via:

sudo gsettings set org.gnome.Vino require-encryption false

let's go on ...

Hi Peter,

Here is the output.

wardh@ubuntu:~$ sudo netstat -tulpen | grep -i 5900
wardh@ubuntu:~$ netstat -tuplen | grep -i 5900
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
wardh@ubuntu:~$ sudo gsettings set org.gnome.Vino require-encryption false

(process:1390): dconf-WARNING **: failed to commit changes to dconf: Error spawning command line “dbus-launch --autolaunch=fc63c12e7cb543e688803e7d144dcc1c --binary-syntax --close-stderr”: Child process exited with code 1

Plus I have attached a screen shot which I did some config as well with dconf-editor.

Hi Ward,
dug a little deeper. There is a confirmed Bug in Ubuntu 17.10 concerning Desktop Sharing.

Sorry for this - until they have finished up this problem i suppose to use teamviewer on both devices . Sorry - no better answer at the moment.
