I already made some videos on the channel about "How to buy a good laptop"which is well worth checking out, one of them about how to buy one with notebook for studies, the other has a more general purpose and is intended to prevent you from falling into the so-called doom combo, but as I mentioned, the idea here is to comment on the behavior travel operating systemSo, let's go to some important information.
I recently went on a relatively long trip, spent about 10 days out, caught a few flights, had some good airport waiting times and hotel room breaks and stuff like that, tried to work with the computer whenever the internet got me. favored.
The computer was powerful enough to make even the most basic video editions, but my primary use really was surfing the internet, checking emails and social networks, communication apps like Slack, Messenger and Telegram, and writing. text and lightweight image editing (with GIMP).
The computer has a relatively low resolution by today's standards, but enough to do the work I hope to do with it, 1366×768, on a 12-inch touchscreen.
Modifications to Ubuntu and GNOME
By default Ubuntu 19.04 runs on X.org, it is the classic graphical server of the Linux distros, stable and works very well, but for those using open source drivers (especially Intel and AMD boards), Wayland It can now work perfectly, except for one or another specific application that, with luck, you don't have to use.
In the Ubuntu login screen you can select which one you prefer to use and suggest you use Wayland (note your needs, preferences and Apps you use), it can be more efficient and make GNOME more fluid in Ubuntu in many cases. At least that's what I felt using a computer as I described it.
Apart from this way of using Wayland, I practically didn't make any modifications to Ubuntu, but I made an adjustment and added an application.
Learning from Who Today's Example
I confess that I was in doubt about taking Ubuntu or Pop! as my travel computer's operating system and although I have heard very well about the System76 project and myself have proven its quality, the truth is that I don't have much time with him to trust 100% (sorry, who knows next), so I put Ubuntu, which I know I never have problems and if eventually something came up (which didn't happen), I could easily solve it.
Although I did not take the Pop! For the trip, one of his features is actually very interesting for these circumstances.
If you saw Pop! _OS version 19.04 review on our channel, you may remember that we mentioned about such a battery manager, as well, as expected, the life of the computer out of the socket is an important point in a trip, so I found it interesting to add software. that we showed here on the blog recently called Slimbook Battery Manager, a software that does the same thing as the settings of Pop! _OS, but a part App is developed by the company Slimbook, responsible for selling Laptops with this brand, especially in Europe. I will not explain this App too much as we have a full article about him here on the blog, as I mentioned, but to give you an idea, he assigns drum profiles like Energy Saving, Balanced and Maximium Performance, as well as having a really cool advanced mode where you can set up some details. Putting the computer into power save mode with this software, it reduces the brightness of your screen as well, which in itself helps.
I recommend turn off the automatic screen brightness that GNOME has on Ubuntu, You can easily do this from the control panel. My advice, to save battery power in this regard let the brightness at the lowest possible level be enough to view the activities.
This setting gave me more than 6 hours of battery, which is a very good thing, but it also slows down computer performance a little, because of the power control application, which slows down the CPU clock and can turn off some other things, such as Bluetooth and Wi-Fi. You can also make fine settings of the power profile if you like, to choose to turn it on and off as you please.
Public Wi-Fi Stuff
One of the problems of accessing the internet at airports is precisely the Public wifi. I strongly recommend that you use your Smartphone to create a private hotspot with your mobile internet, with a good password to access the internet. Let's not forget that it is quite simple to set up a VPN on Ubuntu / GNOME, such as an OpenVPN you have, but I think that is a matter for another time.
When you connect to a public Wi-Fi using Linux, you are generally safer, however, there is no Linux to handle a good phishing attack. Social engineering is designed to fool you, the user, and it is no use a safe system if you expose yourself.
It's not so hard to create a fake authentication page named Airport free Wi-Fi or something like an AP and capture some data, so pay attention!
These authentication pages are quite common, but I remember that I made trips with a Linux Mint and a KDE Neon and the window that usually opens so you can read the connection terms and connect did not appear. I remember that at the time I was tracking the address of the router that gave me this access to be able to enter his browser IP to access this page and authenticate.
Such a problem never happened to me in GNOME distros and also in elementary OS, when connecting to a network in type, a window that pulls the address http://nmcheck.gnome.org open, if you don't see anything in the window, even after giving an "F5", chances are you'll be able to access the address from any browser, like a Firefox or Google Chrome of life, thus allowing you to log in.
A peaceful experience
I can't say that I had any problem with using Ubuntu on the trip in any situation. I took with me a system that runs all the Apps I need, even though I have more limited hardware, a battery that has been lasting a lot (even surprisingly), with a quiet internet connection, either via Hotspot or via Wi-Fi. public. You can't say it's not interesting to open a laptop full of Linux stickers in the middle of a bunch of macbooks and generate some glances eventually.
I am finalizing this text from Port 211, Terminal 2 of Guarulhos Airport, So Paulo, before embarking on my return home on this exact laptop and with the settings I described.
See you next time!
