When you start out with elementary OS there are a couple of useful things that you should do to have  a better experience working with your system.

General

“Software & Updates” for Additional Drivers

The easiest way to install the proprietary NVidia Drivers (in Ubuntu) is to go to System Settings > Additional Drivers and then simply select the driver.

This option is not available in Elementary. However by installing the package software-properties-gtk you can get the program.

sudo apt install -y software-properties-gtk

Now by clicking on Applications on the top right, and then type
“Software & Updates” you can access the Settings.

Easy way to add PPA

With the command line tool add-apt-repository you have a quick way to add additional PPA’s. To get this tool you need to install the package

sudo apt-get install software-properties-common

Add a Minimize Button to Windows

Some of the Elementary Windows do not have an easy way to minimize the window.  With Elementary Tweaks you can add a button to the windows.

Officially the elementary team does not encourage users to use the tweaking tool, since it also exposes switches to functionality that could mess up your system, so use the tool with caution.

sudo add-apt-repository ppa:philip.scott/elementary-tweaks
sudo apt install elementary-tweaks
