How to install Ubuntu with GUI

October 12, 2016 8.9k views
Linux Basics Ubuntu 16.04

Hi - Can someone help me setup a GUI on a fresh Ubuntu 16.04 server? I've taken the following steps:

1) Setup droplet
2) sudo apt-get update
3) sudo apt-get install ubuntu-desktop
4) sudo apt-get install ubuntu-gnome-desktop
5) sudo apt-get install gnome-core
6) reboot

I re-ssh into the server but the GUI does not appear. So I run 'startx' and I get the following message:

Hi @jtn1490 ,
You can't just SSH into server and type startx to get Ubuntu with GUI.
You should use X11 Forwarding or VNC to get what you want.

First solution will not get you a full GUI, but you when you launch any GUI app, it will forward it to you.
Second solution will get you full GUI, so you can go with it.

How to enable X11 Forwarding
To use it, it needs to be enabled on server-side. Open SSH config,

  • sudo nano /etc/ssh/sshd_config

and try to locate X11Forwarding line.
You need to make sure it is not commented (there is no # on beginning of line), and it is set to yes.
Basicly, it should look like

X11Forwarding yes

Now you can try to SSH with following command:

  • ssh -X your-user@droplet_IP

It will show you normal prompt, but if you try to run any GUI app (e.g. libreoffice).
You will see apps GUI just like when you run on your local machine.

Problems troubleshooting:
If you get into any problem while SSH-ing, make sure you have installed xauth on your local machine!

How to install and configure VNC
How to Install and Configure VNC on Ubuntu 16.04 should help you learn more about it and how to install. With this solution, you are getting full GUI, just like on normal machine.

If you get into any problem, feel free to ask :)

How to Install and Configure VNC on Ubuntu 16.04
In this guide, we will be setting up VNC on a Ubuntu 16.04 server and connecting to it securely through an SSH tunnel. The VNC server we will be using is TightVNC, a fast and lightweight remote control package. This choice will ensure that our VNC connection will be smooth and stable even on slower internet connections.

Hi - I followed the 'How to install and configure VNC' guide verbatim. However, in Step3 - Testing the VNC Desktop, I keep getting the error "The connection was refused by the host computer". I am using VNC Viewer. I typed in the same IP address that I SSH into (which works).. Do you know what might be going on?

Thanks!
