End of the Year Report – Librem 5 – Things are awesome

Hello everyone! We have accomplished so much in the last 3 months and need to share, so prepare yourself for a dense update on the Librem 5 phone, PureOS, and software applications.

As you know, we have a number of important components in the Librem 5 that we will try outline.


Let’s start off with the Calls application.  The calls application is what allows us to place phone calls and what makes the phone a
phone.  In these past few months, we’ve been making this application work wonderfully.  Below is a demo of the calls application receiving a phone call.  So the basic support for the calls application is complete and we’re working making a great design.  We’ve successfully implemented important basic features like ring tones.

If you’re interested in following the work, we’ve included the merge
requests for calls below and important issues that were created:

Hægtesse is a daemon to transfer audio data between a modem and PulseAudio.  It currently only supports the SIMCom SIM7100 modem but may be useful for other modems.  The purpose of Hægtesse is to monitor the modem and when a call is initial to configure PulseAudio automatically for a phone call.  This is a necessary component for phone calls.

Libhandy is a library that extends GTK+ to be used on mobile profiles.  With libhandy, you can port any GTK3 or higher app that you have into a mobile profile.  If you have an application written in GTK3, reach out and we’d be happy to help you port it to libhandy.  To find out more about libhandy go here:
https://source.puri.sm/Librem5/libhandy/wikis/home for our roadmap.

Here is an example of GNOME Web (epiphany) ported libhandy

Documentation and example code.

Libhandy has had made significant advancements these months with several releases made.

Libhandy is currently being used to port many core GNOME apps to the librem5

Virtboard is our virtual keyboard used on the Librem 5.  Work has been on-going in enabling the virtual keyboard mostly focusing on making this input working under wayland.  The UX experience is still on-going.  Feedback is of course encouraged.

Chatty is our combination SMS and encrypted communication app.  Chatty currently works with SMS and with the help of libpurple we can also have E2E encrypted communication as promised before.

We currently can successfully send SMS between phones.  Below is a demo of the chatty doing some emoticons.  You might recall last post we showed chatty doing real SMS.  The UX experience is still on-going and continues to evolve.  Follow along in this issue –

Most of our design is being done in GNOME upstream except of course for the UX experience in the Librem 5 specific component.  Purism believes deeply in working in the upstream and we work closely with GNOME’s designers.  Below are a number of design mockups that were conceived for various GNOME apps to work with libhandy.

In addition, a lot of work has gone in to designing parts of GNOME like the control center to work in a mobile context.


WLroot is the Wayland implementation for the Librem5 and which phosh our UX shell runs on.  Mostly working on getting libinput working.  We did some investigations on using rust bindings, but turned out that it was more work with very little advantage.

Merge requests:
https://packages.debian.org/source/experimental/wlroots – update debian packaging
https://source.puri.sm/Librem5/wlroots/merge_requests/35 – input-method and text-input support to the Librem5
https://source.puri.sm/Librem5/wlroots/merge_requests/40 – wlroots update


https://source.puri.sm/Librem5/wlroots/issues/6 – rootston freezes on ssh log out
https://source.puri.sm/Librem5/wlroots/issues/18 – rootston often freezes


Phosh is the actual visual look and feel of the Librem 5.  The most significant work here is being able to detect idle and dim the screen automatically when not on battery power.  Some work on the lock shield was also done and various UX fixes and features.
For more information see the merge requests before.

Upstream Work

Purism knows it stands on the shoulders of giants.  We would not be be successful without our upstream partners.  We make sure that our technical debt is as small as possible, preferring to work in upstream as much as a matter of course.  Below is a list of the work we have done in the various upstreams that we depend on.  This is not an exhaustive list of projects since we do other upstream work for our laptops as well.

We are very proud of our upstream work and being part of these upstream projects.

This effort can never survive without documentation.  In that regard, welcome David Boddie to the Librem 5 team working on documentation for the Librem 5.  The whole team, while focusing on their development, are equally aware of the role of documentation and have worked diligently in making sure that people create applications for the Librem 5.  With two members working exclusively on documentation and developer experience, we hope to make writing applications for the Librem 5 as easy as it can be.  Feedback in improving our documentation would be most welcome!

A lot of focus was made on creating documentation on how to create Librem 5 applications with sample code.

Phone hardware/Dev Kit

The recent shipping of the Librem 5 dev kit represents countless hours of work with an aggressive schedule.  Nicole, Eric, and Petra, along with dedicated operations staff, worked continuously for a week to package all the dev kits to be shipped out to our dev kit backers.

When it comes to software and hardware freedom, we not only do the talk, we do the walk.  Everything in the dev kit, is licensed under the GNU GPL v3+.  We have released the schematics for the dev kit and all source files.  We encourage you to participate and bring your talents and join us!

By now everyone who ordered a dev kit would have received it and are working on the hardware to get it fully enabled from the LCD panel to user-controlled LEDs.  We will be sharing more photos and videos of the dev kits in action as more and more community members advance the software around them.

In the meanwhile, our matrix channel has become a hot bed of activity as people prod and poke their dev kits, asking questions and following along with the devleopment of the phone.

As for the phone, we have confirmed the BOM (Bill of Materials) and the sourcing of parts, we are only finalizing the I.MX 8M or 8M Mini by benchmark testing. Once we have approved the design (also planned in January) we can create the necessary molds and stamps.

January is going to be really busy for Purism as we split time between the dev kit advancements and then pivoting to the Librem 5 phone hardware, but we welcome the excitement around what we’re doing.  We will have a retrospective post on the dev kit tomorow (2019-01-09), so stay tuned for that!

Short Summary of the work:
– Moved to Kernel 4.18.11
– Reworked device tree for dev kit
– add texture support on GC7000   https://source.puri.sm/guido.gunther/mesa/tree/gc7000-bo-relocs,   https://source.puri.sm/guido.gunther/mesa/tree/gc7000-bo-relocs
– PureOS now building on our build server using Laniakea build system
– a mechanical issue was discovered with the M.2 module not sitting flush against the board so a taller M.2 connector was used on the final dev kit design
– RedPine fixing the W_DISABLE# issue, they will use a bodge wire for our 340 dev kit units so that the HKS works as anticipated
– Fixed various issues in the nwl-dsl (mipi) driver
– picture of working HDMI – https://talk.puri.sm/_matrix/media/v1/download/talk.puri.sm/SSvCOnFIIdtgeXqmrMrjZkje
– Fixup several bugs in the imx8ms mipi dsi layer

– Initial (WIP) LCD panel driver
+ Look at haptic sensor. Driven by the kernel’s joystick force feedback
interface (and therefore exposed to userspace as an input
device). We’ll need write a tiny driver for that.

Purism in the Public

Purism employees are not hermits and you can find them at various conferences.  Here are some of the things our employees have done.

– Dorota: Gave a talk based on Rust+Wayland research, dutifully credited Purism (video incoming… at some point): http://rust.cologne/2018/10/10/at-cisco.html

– Adrien and Francois were at Capitole du Libre, running the GNOME booth there.

FOSDEM – A number of us will be at FOSDEM doing talks and hanging out.  More information on what our plans are for FOSDEM in another post.


That’s all for now!  Stay tuned on these pages for new applications, the retrospective on the dev kit, and other features!  Things are rolling fast!  Thank you to our fans for making 2018 a wonderful year and looking forward to 2019!  It’s going to be awesome!  Thank you for a great year!
