My Lenovo ThinkPad and Ubuntu

Filed under
Ubuntu

At Saturday 10 October 2020 finally I purchased Lenovo ThinkPad that I wanted for a long time. It replaces my old laptops Asus and Acer which are already unusable for all my works especially here at Ubuntu Buzz. Now I have a decent computer to write Ubuntu articles I love here. As an avid Ubuntu user, of course I tested it immediately with 20.04 and it made me so happy everything runs faster and better. I feel it is perfect. It is a T430 from 2012 with Intel Core i5 and four GB memory and 320 GB hard disk drive plus its trademark red trackpad and everything else. I found it new by price Rp2,5 millions or roughly $169 so I think I’m lucky. I now can recommend ThinkPad to everyone especially those who want laptop to run GNU/Linux and Free Software. To share my happiness with you, below I listed details of my ThinkPad with important notes.

  • Ubuntu Touch Q&A 86 | Ubports

    The UBports Open-Cuts link is accessible within the forum and provides a dashboard where you will be able to navigate around a structured feedback system on aspects of the software, including (and beginning with) the installer. If you click to the installer feedback page you will see that it is organized by version. The page will direct you to a test protocol designed for a specific element, so that we can have structured rather than accidental testing. The page also shows how many tests have been carried out in total and shows a summary of their outcome. It is possible for testers to upload log-files here. There are even graphs, so you can see the progress of testing more clearly. There is a lot more detail on the installer pages than elsewhere at the moment, as we are using this module to explore the functioning of this new approach to testing. As we learn from this and it becomes more robust, we can start to extend the same mechanisms to other modules. As explained, the installer will itself be able to populate Open-Cuts fields in real time, subject to consent from the user. As usual, the installer is built from a java-script variant. It uses a Mongoose client for that, which is helpful if you want to get involved but are not very familiar with Java-script. If you are a Mongoose specialist (MongoDB), definitely get in touch!

  • UBports Improving Its Installer For Deploying Ubuntu Touch On Smartphones - Phoronix

    The UBports community that continues advancing the Ubuntu Touch mobile platform has been working on improvements to its installer. 

    The UBports installer is out with a new beta that enables Samsung support, can now be used behind a network proxy, and has a number of other installation fixes. With this beta, the Google Nexus 6P is also now supported for installing Ubuntu Touch on it.

The F(x)tec Pro1-X is certainly not your typical Android smartphone, as it offers the choice of LineageOS or Ubuntu Touch operating systems out of the box.

The LineageOS is essentially a refined Android that has advanced controls and privacy permissions, whereas the Ubuntu Touch offers users capabilities of a fully-fledged Linux PC. The smartphone has a landscape-optimized launcher and supports customizable shortcut, but since far not all Google Android applications are optimized for hardware keyboards, not all programs will be able to take full advantage of the device.

The F(x)tec Pro1-X can be connected to a display using a USB Type-C cable and be used like a regular Linux personal computer. The touchscreen display can act like a trackpad, whereas the keyboard can be used to input text.

  • Homelab clusters: LXD micro cloud on Raspberry Pi

    Running or testing workloads at home, safely, still has issues. There are lots of ways to do it, maybe you have a dedicated homelab in your basement, or you run workloads on your main machine, or something in between. But every method has drawbacks. People want something that doesn’t take up racks of space, that is quiet enough not to be in a different room, and won’t cost an arm and a leg.

    Previously you had to use cloud technology, fork out the cash, or let go of your homelab dreams forever. But this all changes with the LXD Ubuntu Appliance. A smaller, quieter and comparably inexpensive way to spin up and manage all the VMs and containers you need.

  • Canonical & Ubuntu at Open Infrastructure Summit 2020

    This year we’ve probably used the word ‘unprecedented’ almost as often as we’ve said ‘Linux’ and yet life must go on, and certainly so does tech. That’s why we were so thrilled to hear that Open Infrastructure Summit (OIS) will indeed take place this year too (virtually of course) – especially considering how solid the interest around OpenStack is today, and Canonical’s ongoing commitment to this technology and community.

    [...]

    This year, Canonical founder Mark Shuttleworth will be joining the community again to set the tone for the event with a few words on where the future of open infrastructure is headed.

  • First UbuntuDDE Remix 20.10 Groovy Beta Is Released

    UbuntuDDE Remix 20.10 Groovy Beta is a GNU/Linux distribution based on the Ubuntu 20.10 Groovy Gorilla beta released last week. It features the latest version of the very user-friendly yet powerful Deepin Desktop Environment instead of the laughable and utterly useless tablet/smart-TV desktop environment Ubuntu's regular release ships with. This beta-release is primarily for testers. We tested it and we liked it.

Emilia Torino shares what goes into keeping Ubuntu secure

Interviews
Ubuntu

I’m from Argentina, and I did my undergrad in software engineering here. I worked for Intel in Argentina for six years – first as an intern and then as a fully-fledged software engineer. Then I received a Fulbright scholarship to do my master’s degree at Carnegie Mellon University in the United States. After finishing my Masters, I went back to Intel and then McAfee for a few more years, and then joined Canonical in 2019 as a Security Generalist.

I was looking for a new challenge. Even though I had more than ten years of industry experience and had been involved in security activities, the prospect of working for the team that makes Ubuntu secure was more than exciting! What’s more, I hadn’t previously been that deeply involved in open source projects. I knew that joining Canonical would offer different learning and career opportunities.

Automatic Theme Installation for Snap Apps is Shaping Up Nicely [Video]

Filed under
Ubuntu

But that method relies on the theme you’re using being in the common themes Snap bundle (which for older, niche, or brand new themes is unlikely).

Earlier this year we touched on the (growing) availability of GTK themes as Snap apps. That effort improves the “Snap theming” situation greatly: you install a GTK theme, install the relevant theme Snap, and …then you run a copy/paste a series of complex (and unmemorable) commands to get the theme to take effect on your Snap apps.

But things are improving.

Canonical’s Marcus Tomlinson shares an update on automatic theme installation for snaps. He says that “…whenever you install and apply a new theme to your desktop, a background service will check if its associated theme snap is installed, and, if not, ask if you’d like to install it.”

First Look: Ubuntu 20.10 Wallpaper Revealed – But is it Groovy Enough?

Filed under
Ubuntu

When the Ubuntu 20.10 beta arrived last week it did so without a new background image. This had some (well, me) worrying that the upcoming release wouldn’t ship with a new wallpaper at all.

But no fear: the Groovy Gorilla is now here.

Ubuntu devs are gearing up to release the Groovy Gorilla to a global audience, having put in a gallant six-months of groundwork so far. But every great Ubuntu release needs a great wallpaper to go alongside it.

Filed under
Ubuntu

Development on Ubuntu 20.10 kicked off earlier this year, shortly after the launch of Ubuntu 20.04 LTS (Focal Fossa), but since it’s not a long-term supported (LTS) series, there aren’t any major new features and enhancements to be expected in the upcoming release.

The biggest things you already know about them. Ubuntu 20.10 will be shipping with the latest and greatest Linux 5.8 kernel series, which, of course, brings better hardware support, as well as the latest and greatest GNOME 3.38 desktop environment, which I took for a first look this week.

Devices/Embedded: MiTAC, Raspberry Pi and ESP32/Arduino

  • Fanless Linux embedded system makes a compact IoT gateway

    ICP Germany has recently introduced the MiTAC ME1-8MD series family of compact, fanless Linux embedded systems powered by NXP i.MX 8M processor and designed to be used as IoT gateways, data acquisition and processing systems, and mini servers. Three models have been launched with a choice of dual or quad-core processors, up to 4GB LPDDR4 RAM, and 32GB eMMC flash storage. The embedded computers also come with up to two Ethernet ports, support up to two displays, and include an internal Raspberry Pi compatible 40 pin GPIO header.

  • Official Raspberry Pi 4 case fan adds cooling to Raspberry Pi 4 case

    When the Raspberry Pi Foundation first introduced the Raspberry Pi 4, they claimed the board would work just fine under most cases without a heatsink, and the latter was only really needed under load. That may have been true when using the board in a temperate climate like in the United Kingdom, but then Raspberry Pi 4 met Thailand with some benchmarks results lower than on a Raspberry Pi 3. People using plastic enclosures had even more troubles. It’s only when I installed a heatsink on Raspberry Pi 4 that the board could really shine. The company also provided some firmware optimizations later on to further cool-down the board. But you can only do much with software, and many third-party cooling solutions such as fansinks or metal cases have been introduced for the popular SBC.

Linux Kernel: Greg Kroah-Hartman's Talk and Panics

  • Greg Kroah-Hartman: Lessons for Developers from 20 Years of Linux Kernel Work [Ed: "The Linux Foundation is a sponsor of The New Stack" for the latter to write puff pieces such as these, so it's basically marketing]
  • Greg Kroah-Hartman: 'Don't Make Users Mad'

    Kroah-Hartman explains that one of Linus Torvalds' most deeply-held convictions: don't break userspace. "Other operating systems have this rule as well — it's a very solid rule — because we always want you to upgrade. And we want you to upgrade without worrying about it. We don't want you to feel scared. If you see a new release, and we say, 'Hey, this fixes a bunch of problems,' we don't want you to feel worried about taking that. That's really really important — especially with security...." If you do make a change, make sure there truly is a compelling reason. "You have to provide enough reason and enough goodness to force somebody to take the time to learn to do something else. That's very rare." His example of this was systemd, which unified a variety of service configurations and initialization processes. "They did it right. They provided all the functionality, they solved a real problem that was there. They unified all these existing tools and problems in such a way that it was just so much better to use, and it provided enough impetus that everybody was willing to do the work to modify their own stuff and move to the new model. It worked. People still complain about it, but it worked. Everybody switched... It works well. It solves a real problem. "That was an example of how you can provide a compelling reason to move on — and make the change."

  • What to do in case of a Linux kernel panic

    Linux is used everywhere in the IT world. You've probably used Linux today, even if you didn't realize it. If you have learned anything about Linux, then you know it is indeed a kernel. The kernel is the primary unit of the Linux operating system (OS) and is responsible for communications between a computer's hardware and its processes. In this article, you will learn about one situation related to the Linux kernel: The kernel panic. The term itself can make you panic, but if you have the proper knowledge, then you can remain calm. Every system admin faces this issue at least once in their career, but reinstalling the system is not the first solution you should turn to. [...] Now, anytime you see a kernel panic error, you will definitely not panic because you know why this error occurred and how to resolve it. This article covers one of the common Linux boot problems: kernel panic. There are so many other potential boot problems that can occur in Linux, but resolving those issues will become much less of a panic when you gain some advanced knowledge of your system.
