What we do

We support the open source community by providing a resource of information, and a forum for debate. We help all readers get more from Linux with our tutorials section – we’ve something for everyone! We license all the source code we print in our tutorials section under the GNU GPL v3. We give you the most accurate, unbiased and up-to-date information on all things Linux.

Who we are

This issue we asked our experts: We’re helping people put Windows far, far behind them this month, but what would you like to escape from in the Linux world? Jonni Bidwell I’d like to escape from having to mute and unmute my soundcard in order to stop it making terrible noises while it attempts to play music. Gotta love PulseAudio and its weird post-wake-from-suspend ways. And also psytrance (psychedelic trance), which my cohabiters describe as terrible noises.

Neil Bothwick The attitude that Linux is just for Windows users who don’t want to pay for their software. Concentrating on the free (especially as in beer) aspect, detracts from the quality and range of software available. Please escape from Windows to Linux, but because it’s better, not cheaper.

Nate Drake I’m mystified by the zealous frenzy of advocates of various flavours of Linux, particularly when they criticise Ubuntu for having the audacity to be flexible and easy to use. Do we want to give Linux to the people, or show how terribly clever we are because we can compile our own kernel?

Nick Peers I’d like to get rid of most subscriptionbased services. This obsession with making us pay time after time for the privilege of using a particular program, watching a video or listening to music does my head in. If I buy something, it’s for keeps. And I want to be able to format-shift it, too.

Les Pounder You know I could insert a joke about wanting to escape from Vim here, Esc :wq!, but I won’t...oh wait, I did. I’ve nothing bad to say about Vim/vi but I much prefer nano. So my escape tip for people who want to up their text-editing game, is to learn how to quit Vim/vi, then learn how to use it.

Open your mind Don’t use Linux because it’s free, but because it frees you and your hardware. We’re not here to bash Windows, we’re here to give you choice. When you buy a Mac you have to run MacOS. Buy a PC and you’ll be steered in the direction of Windows 10. I’m not even going to mention tablets, phones, TVs and even cars. All are examples of companies attempting to lock-in consumers to a walled software ecosystem. When you own the hardware, why is the software you can run being dictated to you? The PC is a general-purpose computing engine. It should and usually can run any software you like – though recent examples show even the PC is being walled off through its firmware. That’s where open source Linux-based OSes come into play. If you believe you shouldn’t be locked out of hardware that you own, then that’s just one reason open source software is so vital to the world. For us older types, another reason is the fun of getting to play with the inner workings of the OS – something that modern devices and their OSes are making increasingly difficult. Even if you don’t accept the privacy and spying arguments for open hardware and software, surely having full ownership and control over the devices you buy is important? I feel you shouldn’t have to be beholden to huge corporations to do basic computing, worry about what personal information they’re retaining, or forced to use specific types of software. To help everyone enjoy this freedom this issue we’ve got a huge 16-page guide to installing and using Linux, no matter if you’re a novice or computing expert. We have a guide to configuring the Linux desktop in its many forms, while the rest of the magazine offers a small glimpse of the wide range of open source topics, ranging from security and coding to the Raspberry Pi, training and creative tools. There’s never been so much interest in Linux and open source. It’s never been so widely used before, there’s never been so many opportunities to use it, and the quality of the software has never been so high. Enjoy!

This ISSUE: Linux on smartphones

Mobile devices

Smartphone Linux – don’t dream it’s over

Canonical may have finally pulled the plug on Ubuntu Phone, but don’t fret – there are still determined developers who are keen to get Linux running on your smartphone.


few months ago in LXF224 we reported how Canonical was dropping Ubuntu Phone, along with ambitions to put a version of its Linux distro on smartphones. If that’s left you despondent, then the good news is there are a number of ways to get Ubuntu – and other forms of Linux – on your smartphone, with the demise of Ubuntu Phone giving these other platforms more visibility as people search for alternatives. One of the most popular alternatives is UBports (, which has been around for a while now, but is gaining attention as an alternative to Ubuntu Phone. Originally created as a way to bring Ubuntu Touch to more devices, the team behind UBports has announced that the project’s gained new sponsors, Private Internet Access (, while its Patreon crowd-funding site has hit $1,500. The growing interest for UBports has been helped by Canonical’s move to ditch Ubuntu Touch, according to the UBports community update ( It’s also been announced that every official Ubuntu Touch device now works with UBports Ubuntu Touch images, which is encouraging news for owners of those devices who were worried that Canoncial’s move would leave them with unsupported devices. Meanwhile, work continues on UBports support for Google’s Nexus 4 and Nexus 7 devices, which were popular ways for users to add Ubuntu Touch themselves via unofficial flashing.

6     LXF226 August 2017

To find out how to install UBports images on your device, check out the comprehensive guide at: There’s more good news for people who want to run Linux on their smartphones and tablets, with the news that significant progress is being made on the Halium ( project. Halium was designed to provide a single base that includes the Linux kernel, Android Hardware Abstraction Layer (HAL) and libhybris. This would make it easier for developers to bring non-Android operating systems to Android devices. Rather than mobile GNU/Linux projects such as Sailfish OS, Mer and Plasma Mobile working on their own solutions separately, developers can access Project Halium to use HAL to work on the proprietary bits of a smartphone or tablet, with the kernel providing the source code and libhyrbis bringing Android libraries to Linux. Halium is now able to boot Ubuntu 16.04 with a basic Android container, and while it’s early days, some

Canonical has abandoned Ubuntu Touch and Google has dropped the Nexus 5, but Linux could still appear on a smartphone.

Project Halium is a noble endeavour and we’d love to see Linux-on-mobile projects take it on board, but time will tell whether or not they do. So, despite Canoncial’s actions, the Linux-on-smartphones dream continues to live on, thanks to a passionate community who are eager to carry on where bigger companies fear to tread – or simply lose interest. Smaller projects such as postmarketOS (, which aims to provide a touchoptimised, preconfigured Alpine Linux with own packages for older smartphones, no matter what their make or model, prove that there’s still a passion for getting the world’s best operating system on to as many mobile devices as possible. We’ll look into this subject in a future issue….

“So despite Canoncial’s actions, the Linux-on-smartphones dream continues to live on…” important features are now working in 16.04, such as Mir, Wi-Fi and Bluetooth support, along with sound and voice calling (pretty essential for a phone), and adb and ssh for debugging.

Newsdesk Legal

GPL remains strong and stable Good news, everyone! US court rules that GNU General Public Licence can be enforced as a licence and a contract.


ince Richard Stallman released the first version of the GNU General Public Licence (GPL) back in 1989, the licence has been a linchpin of open source’s success, by guaranteeing that end users are free to run, study, share and modify any software that comes with the licence. In 2008, a case in the US appeals court (Jacobsen vs Katzer) reiterated that open source license conditions are enforceable as a copyright condition. Basically, the GPL is a licence that depends on copyright law for enforcement, and that it was a copyright licence − not a contract. You can read more about this ruling in an in-depth article at Now, a new ruling (Artifex vs Hancom) clarifies the legal basis of the GPL. This case came to be when Artifex Software, the company that owned Ghostscript and provided a dual-licencing method where people could use the interpreter for the PostScript language under the GNU GPL, or using a conventional proprietary licence, discovered that Hancom, a South Korean company, was using Ghostscript without either type of licence.

GPL’s future is more certain than Theresa May’s.

Artifex took legal action, alleging copyright infringement and breach of contract, which Hancom denied. However, the court ruled that the GNU GPL is a contract. The court also upheld the result of the Jacobsen vs Katzer case, which means the GNU GPL is also a licence, and damages could still be awarded. With Artifex now able to proceed with its case against Hancom, the legal position on the GPL has been made much clearer – which could have ramifications for other contracts that relate to free software. We shall be keeping an eye on this.

Machine learning

Linux kernel boost

Heterogenous memory management lends a helping hand.


eterogenous memory management (HMM) could soon be making its way to the Linux kernel, which could give the OS a major boost when it comes to machine-learning applications and other GPU-powered tasks. HMM enables device drivers to mirror the address space for a process under its own memory management. So a graphics card could directly access the memory of a process without having to copy anything or putting at risk an OS’s memory protection feature. Basically, this can give a hefty speed boost to GPU-based machine learning, with libraries such as Nvidia’s CUDA, as well as OpenCL. While this is an exciting development, you’ll need to keep your expectations in check for now. For a start, HMM needs to be committed to the Linux kernel, and this was first proposed back in 2014, so it obviously

is taking quite a while to implement. It’s also likely that you will need a new – and expensive – graphics card to make use of HMM – at the moment only Nvidia’s high-end Pascal GPUs support the feature. So, while there may be a bit of time left until we see HMM support in the kernel, we’d best start saving for a compatible GPU now.

You’ll need a hefty graphics card to make use of HMM.

Newsbytes A Sudo vulnerability has been found – and quickly patched – that enabled a local attacker to gain root privileges. The issue, known as CVE-2017-1000367, made it possible for malicious users to run bash commands to overwrite files – even root-owned data. The security researchers from Qualys revealed that, “We discovered a vulnerability in Sudo’s get_process_ttyname() for Linux: this function opens “/proc/ [pid]/stat” (man proc) and reads the device number of the tty from field 7 (tty_nr)”. Red Hat, Debian and other distros – especially ones with SELinux enabled, have been patched. To find out more read the security advisory at There are now 3,500 Linux games on Steam, the popular store (and DRM enabler) for PC games. These titles range from quirky indie games such as Terrari, to blockbuster games like Total War: Warhammer and Metro 2033. With a huge library that’s constantly growing – and bear in mind this is only games available in Steam, other methods of buying games are available – it’s never been better to become a Linux gamer, or to convince PC gamers to dump Windows. To see the full list, head to search/?category1=998&os=linux. Elsewhere we’ve talked about getting Linux to work on Android devices, but what about the reverse (sort of)? Anbox ( – also known as Android in a Box, enables you to operate Android apps within Linux. It does this by running Android apps in a container, while integrating them as if they were a native application. This potentially opens up Linux to a huge range of apps, and with the launch of Android O coming later this year, even more functionality should be made available to Linux machines. It’s early days so far for the software, but it’s extremely promising. Watch this space!

Run Android apps in Linux with the useful Anbox software.

Newsdesk Comment

Continuous integration Mark Filion At Collabora, the majority of our customers use the Linux kernel directly within their products. However, a lot of our customers are modifying the kernel to adapt it to their specific needs. While this highlights the flexible nature of Linux, it also creates a problem for these companies because they end up working with an outdated kernel that’s no longer receiving vital security updates. The kernel that shipped with its product has become so heavily modified compared to upstream versions that rebasing it on top of newer, mainline releases becomes too expensive and difficult to plan for. Staying close to upstream as much as possible , by regularly rebasing on top of new releases (typically LTS releases) is the best solution. However, for this work to be feasible, the amount of differences between mainline and downstream sources needs to be manageable. That’s why we recommend contributing back any changes that aren’t specific to their products. Nevertheless, while some companies have upstreaming processes, keeping up with the mainline can take time. Collabora has been working on continuous integration of software components across a range of hardware. This includes sponsoring one of the major efforts to integrate the mainline Linux kernel codebase:, which builds several configurations of different trees and submits boot jobs to several labs around the world, and collates the results. This plays a key role in detecting any changes that either break the builds, or prevent a piece of hardware from completing the boot stage. Along with helping you keep pace with the Linux kernel, having continuous integration of changes in mainline reduces the risk of introducing regressions to your kernel and makes it easier, and faster, for your contributions to be accepted.

Over the past decade we’ve seen virtualisation fully mature in the data centre. It’s now beginning to move into the embedded space – largely thanks to the low-power devices being produced by Intel and ARM. Virtualisation provides these environments with the same benefits it has for the data centre. First, it makes possible the merging of workloads on to a smaller set of hardware, which reduces costs, power and space usage. Second, the abstraction of the hardware makes it possible for applications to be decoupled from hardware specifics. And third, the benefit of hardware-based isolation results in better protection against software defects – and if any failures occur, they can be contained easily. The hypervisor plays a key role in the virtualisation of embedded systems, especially in use cases like automotive, navigation systems and non safety-critical aviation systems. With automotive and embedded it’s essential to have mature technology, light-weight architecture and a vibrant open source community to meet the performance and compliance needs of these environments. The Xen Project is the top hypervisor choice for embedded systems and automotive because of its maturity, lightweight architecture and open source community. It’s currently being used by GlobalLogic, EPAM, Assured Information Security, BAE systems, Dornerworks and StarLabs. Furthermore, an open source approach to embedded virtualisation brings about standardisation that will benefit embedded and car manufacturers. This, in turn, will lead to reduced costs and greater innovation. More details on the next phase of Xen Project will be discussed during its annual Developer and Design Summit. This takes place on July 11 to 13 in Budapest, Hungary. Lars Kurth has worked in the mobile industry for 16 years and is community manager for

Missing bits Way back in the 1990s I developed The Digital DJ Dance Manager, which ran on a PC with Windows XP Pro. While it was written using Visual Basic 6 I would like to clean it up and rewrite it to run on Linux. The unfortunate thing is that this program enables one to use seven simultaneous displays, which isn’t easily done with any of the Linux distros I’ve seen. While the current release of DJ isn’t pretty, it does get around the irritations which the use of Tabs pose when using an iPad! One display with tabs is not conducive to programs like this, or for businesses such as stocktaking, banking, purchasing and particularly like multidisplay video gaming. When is Linux going to make it easier to add multiple displays to its otherwise powerful

Dell deserves all of the acclaim it’s built with its Linux-powered PCs.

Direct Cable Connection that Windows used to offer to migrate installs, made obsolete by a networked option. Really, you’re asking the company to support Linux with its proprietary cable solution. Much of what you’re after would be achieved using a remote desktop solution such as TightVNC, which enables live screen/mouse/keyboard capture plus drag-and-drop sharing. As for multiple monitors, from what I can tell X11 has supported multiple GPUs with xrandr since v1.4 was released in early 2013, but this needs to go hand-in-hand with driver support, too. It’s not something we’ve tried but all the information does seem to imply Linux can power up to at least 10 displays (in all likelihood more), even across different GPU manufacturers, as long as you have the hardware to do so. Perhaps using proprietary drivers would make things easier?

Everyone loves more than one display, but six? Matrox says yes!

system? I’ve regularly had to use Windows when setting up multi-display systems for use by all of my business clients – they’re addicted to having more that two displays. Another valuable product that seems to be Windows and Apple unique is called a Wormhole! This enables one to easily connect two different systems together via the USB port and have them work as a single computer from just one of their keyboards and trackball. Electro Group, via email Neil says: The classic Achilles’ heel of Linux is where the hardware and software worlds meet. Both the things you mention here really aren’t features, but products offered through hardware vendors. The Wormhole is the easiest to address, I’ve never come across this, but it looks similar to the USB

Dell fanboy I’ve just read your article entitled Launching Linux Laptops in LXF220. I’m a big fan of the Dell XPS Developer and am on my second machine, having passed my old one (2013) to my wife. We’ve been using Linux as our household’s only operating system for about 10 years. The advantage of the Dell developer machines is that you don’t have to remove Windows from a new machine or leave Windows on a separate partition to maintain the warranty if things go wrong. You also don’t have to worry if the PC you’ve bought is really compatible with Linux. The Dell XPS Developer is a superb piece of engineering. Granted, it costs about the same as an Apple machine, but then the Linux software is free, open source and just works, which is certainly not my
