See here to see why you might want to install the Mate flavor of Ubuntu 14.10.
Then, install it and consider doing these things. Get your system up to date. Yes, yes, you just installed it but that install image was old(ish). Update and upgrade now:
First, you probably want to open the Software Center, to to Software and Updates, and enable all the Ubuntu Software Sourcews (other than source and the CDRom option). Then:
sudo apt-get update
sudo apt-get dist-upgrade
Go to Preferences/Additional Drivers and then allow additional drivers, and pick a proprietary driver for your graphics card if you like.
Install the Synaptic Package manager and if you like use it for some of the following updates. I like Synaptic package manager better than the Ubuntu software center.
sudo apt-get install synaptic
You might not need to install gdebi but make sure it is there. This is an application that installs .deb files.
sudo apt-get install gdebi
So now you have a better set of installation tools.
Go to the Google Website and install Chrome. Not Chromium Chrome. Chrome will run Netflix for you. Later, when you run it, it will ask if you want it to be your default browser. Your choice (I use Chrome as my default browser.)
Using Synaptic Package Manager (if you like) you may want to install vlc media player, and your favorite audio software.
I like emacs, you probably don’t, but if you do, this is a good time to install it, and consider updating your .emacs file.
Open up the control center and fiddle with stuff.
You then might want to head on over here and see if you want any of the suggested software for power management or other functionality.
