8. Enable Night Light
Many people who regularly use computers suffer from eye strain and fatigue. Looking at a monitor for a long time can strain your eyes or can make any other problems you are having with your eyes seem more apparent. There is also research to show that late-night exposure to bright lights can affect sleep quality. This can be mitigated by reducing blue-light exposure.
Ubuntu already comes with a tool to reduce the amount of blue-light exposure. You only need to activate the feature.
Open Settings from the Dash. Select Screen Display, and then select the Night Light tab.
In the image below, you can see there’s a slider to enable Night Light.
We have chosen the Sunset to Sunrise schedule, but we can also define a specific time to start and stop the night light. We can also configure the colour temperature.

There’s lots of things some users might want to do after a fresh installation of Ubuntu. It’s impossible to cover them all in a single article. But we’ve covered the fundamentals.
We don’t recommend manually configuring a firewall. iptables is the built in firewall for Ubuntu Desktop. But the default desktop installation has no ports open and no servers running. ufw is software for managing the firewall. It’s also pre-installed but configured to do nothing. For most home Ubuntu users there’s no need to configure either iptables or ufw.
There’s tons of replacements for the software already pre-installed with Ubuntu. For example, many users prefer using Google Chrome rather than Firefox as their web browser even though Chrome is proprietary software. But things like that are largely personal decisions.
Nevertheless, newcomers can easily be bamboozled by the sheer number of open source software available. To help new users, we have assessed many thousands of open source programs from an independent and unbiased view and selected our favorites.
