Stastic Ip Address On Linux Using Gui Intefaces
This brief tutorial describes how to configure static and dynamic IP address in Arch Linux and its derivatives like Antergos and Manjaro Linux etc. First, we will see how to configure static IP address. Netctl is a command-line utility that can be used to introspect and control the state of the. You can use the same method to set a static IP address on a CentOS server with a GUI as well.

How to setup static IP address under Ubuntu 14.04 Trusty?
(NOTE, the question was asked for '14.04 Trusty', but it is still working for now, 16.04 LTS Xenial)
My setting is not working. What special about Ubuntu 14.04 Trusty is that I found it now using the 'source-directory' keyword to source multiple files at once (Ref: http://manpages.debian.org/cgi-bin/man.cgi?query=interfaces&apropos=0&sektion=0&manpath=Debian+unstable+sid&format=html&locale=en):
So I prepared my static IP address setting as this:
However, it has an extensive delay during boot up. I saw the boot up message saying something like 'Bring up Network', then after a long delay later, saying something again like 'Waiting for 60 more seconds to bring up Network'. After that 60 more seconds delay, the boot up messages start to fly again. However, when the system finally boot, and I check the ip addr output, the second static IP address that I configured is not there.
Am I missing something?
UPDATE:
Thanks everyone for pointing out that my gateway was wrong so I changed it to 192.168.2.1, and the long delay in boot is gone. Now I'm getting into a new problem.
For my Ubuntus prior to 14.04 Trusty, the above change is sufficient to switch from dynamic IP to static IP. However, with my new Ubuntu 14.04 Trusty, the system boots up with no IPv4 addresses:
It also gives errors when I was trying to bring down the device:
I am able to bring up the device afterward though, and then ifconfig & ip addr give the correct output. However, the IPv4 address will be gone after a short while.

This is XUbuntu 14.04. Thanks
UPDATE2:
Use /etc/network/interfaces instead. Details in my own answer.

Ok, I ditched Microsoft and change my household computers and laptops to Ubuntu 14.04 :)
After a week long searching the internet how to get a static ip-address on Ubuntu 14.04 I finally found a way ...
It seems the network-manager is overwriting (or by-passing) my /etc/network/interfaces every single time, I thought of removing it but decided on trying to use it first.
Go to the right upper corner and click the network icon, go down to the bottom and right click edit connections.
This opens network connections and choose the connection to change, click edit and go to IPv4 settings. Choose Method: Manual and then fill in the Address, Netmask and Gateway ... and your desired DNS server.
Just save and your done ... it will change to the given static IP-address on the fly ... even after reboot!!
This might be an old thread, but after a week of searching I updated the 10 first hits in Google ... hope to safe other people some time!!
Take care!
Your gateway is incorrect (gateway 192.168.2.0). This is not a valid IP and you should substitute it with your router's IP address.
I think I found the answer, having moved the content from /etc/network/interfaces.d/eth into /etc/network/interfaces, and rebooted, it is working now.
I guess that ifup understand source-directory /etc/network/interfaces.d and can handle it correctly while network manager can't.
May not be configured to your routers correct gateway.
