Debian on mobile devices

Please add some valuable information to help this project move forward. :)

This page is about tracking every initiative to fully or partially install the system on mobile platforms:


Debian is the universal operating system. Thus, it needs to run on mobile devices. This wiki page is a tool to help bring Debian to mobile platforms.

It would be great if Debian could run on many kinds of mobile devices: iPhones, Android capable HW, Windows Mobile HW, tablets, etc.

The software should allow dual booting, into both Debian and any software that came with the hardware.

Debian on mobile devices should have GUI capabilities, appropriate to the hardware capabilities.

It would also be great if Debian could run applications written to be native to the original OS for the hardware. This will enable Debian to serve the many people in society who want to easily use those applications.

Debian might benefit from having its own User Interface, or UIs, based on progression from the desktop Debian UIs - ex, GNOME or KDE. It would be great if the GNOME, KDE and other GUI communities could come to agreement on a common UI for Debian, to save unnecessary duplication of development effort, both of the Debian UI, and application software for Debian. Also to save the users from having to learn unnecessary extra UIs.

Origin and Purpose

To get this wiki page started, see the original message I sent suggesting this project. It includes some reference URLs, to help seed thinking on Debian on smartphones development.


Many people made useful replies to that email, and it would be great if they would add their suggestions of software components, foundations, and URLs thereof to this page. If we all take a few minutes to make contributions to this page when we have something valuable to add, this page will grow to be a great resource for us all. So, please take a moment to add something valuable to this page right now, or when you have the opportunity. :)

This page could use contributions like: Links to component software (embeded debian, GRUB, UIs, etc).

Software developers can write software for the many parts of this system and put links on this page to those components.

Writers can produce articles about Debian on smartphones in emails to the relevant Debian mailing lists, blogs, web pages and for the general media.

Artists can create the graphics and multimedia for Debian on smartphones.

Packagers can put it all together so people can download and install it on their smartphones.

Thanks for reading. Thanks for thinking. Thanks for all contributions you make. Let's all work together to enable Debian to fulfil its promise as "The Universal Operating System". :)


If you want to chat about Debian mobile user interfaces, please join the #debian-mobile IRC channel on irc.debian.org or subscribe to the debian-mobile mailing list. If you are interested in kernel, bootloader or middleware related issues you might want to join the #debian-arm IRC channel instead.

other discussions will be appropriate to have on the following lists instead:


Here are some people interested in running Debian on mobile devices.

More productized stuff via FSO, oFono etc. packaging to support more phones



Learn software development.

Port low-level stuff to a device.

Package some middleware.

Package a user experience.

Package applications that can deal with small screens and touch input.

Build images for users to flash onto the device.

Get hardware to developers.


At various stages you will need to learn some of the following. This can be done at the same time as working on Debian for smartphones.

  • Languages:
    • ARM assembly: Linux, bootloaders
    • C: Linux, bootloaders, UIs
    • make: build systems
    • Python: middleware, applications
    • Vala: middleware, applications
  • Tools:
    • Version control:
      • git: Linux, middleware, applications
      • svn: UI, applications
      • bzr: applications
    • Compilers: GCC, LLVM, GCC cross-compilers
    • Build systems:
      • make: almost everything
      • autotools: middleware, UI, applications
      • cmake: some things
      • other: Linux and bootloaders might have custom build systems based on make


Pick a specific device. Get support for it into a bootloader (u-boot/etc), mainline Linux. Ask relevant teams to build linux/bootloader packages that work on your device. Port the debian installer to the device.

This is most of the work. It is important to get your changes into Linux/u-boot mainline otherwise Debian will not be able to support your device since the Linux kernel team for Debian will not add non-mainline drivers/patches to Debian kernels and therefore you won't be able to support Debian on the phone you care about. It will be made easier since the Android drivers probably already exist and can be ported to mainline Linux. Some hardware vendors will be violating the GPL and not releasing drivers/patches. You might be able to get the code by contacting them or getting the SFLC or gplviolations.org involved.


Pick some middleware, join the packaging group for it or package it for Debian and look for some sponsors.

Existing middleware includes FSO (in Debian), oFono (in Debian), pyNeo, Android/MeeGo/Maemo.


Pick a UI or create a new one, create a team, start packaging it for Debian and look for sponsors.

There are numerous existing FLOSS UXen for smartphones and similar devices. As the universal OS, Debian should aim to support several of these.

  • Android: Canonical allegedly was porting it to Ubuntu two years ago

    • Replicant: aiming to remove all the blobs and non-free stuff from Android

  • MeeGo: there was a general Debian MeeGo packaging team, ?MeeGo is now cancelled

  • Maemo: distribution based on Debian, talk of merging it, pkg-n900 exists

  • GNOME Mobile: seems to be a dead iniative

  • KDE Plasma Active: not yet available in Debian

  • E17/Illume: available in Debian now, packaged by the pkg-e team

  • DeforaOS: releases Debian packages

  • QtMoko: distribution based on Debian

  • PyNeo: distribution based on Debian

  • Qalee: no Debian packaging effort

  • QuantumSTEP: no Debian packaging effort

  • GPE: already in Debian for years. palmtop, no phone component yet, more suitable for stylus based devices.

  • Tizen: mobile distribution based on EFL, Debian/Ubuntu, backed by Samsung and others

  • webOS: mobile distribution based on HTML/JS, ?OpenEmbedded, backed by HP

  • Nemo: mobile distribution based on Mer (RPM), ?MeeGo Handset UX, Qt

  • Cordia: mobile distribution based on Mer (RPM), Maemo Hildon stack ported to newer GTK+/etc

  • Boot to Gecko: Mozilla project to create an web-based OS


Start an index of touch-screen friendly apps and package some of them. Most of them will be ?OpenMoko ones since that was the first free software friendly phone. So read their wiki and related sites a lot.


Talk to the Debian installer, live and CDs teams about building daily, weekly and release images that people can flash onto their phones. This could significantly change the way Debian images are built so it will require a fair bit of discussion first.

Other tips

If you can get hardware into the hands of kernel developers that would help a lot. You might find some hardware manufacturers who are willing to give out some free samples to developers.

  • Debian CPU ports: arm armhf (mailing list, IRC channel)

  • Debian phone ports: OpenMoko FreeRunner, OpenMoko Neo1973, Nokia N900

  • External projects:
    • Emdebian: cut down version of Debian for small and embedded devices

    • FSO: umbrella project for free software on smartphones

    • SHR: distribution for smartphones based on ?OpenEmbedded and FSO softare

    • Linaro: pushes upstream development on ARM, they work on Linux, GCC and related low-level stuff.

    • OsmocomBB: free software for GSM baseband devices, currently only for the baseband on the ?OpenMoko FreeRunner and related devices

  • 3D driver projects:
    • OpenFIMG: FIMG 3DSE core from Samsung ?SoCs (inc ?S3C6410, ?S5P6442 and S5PC100)

    • Lima: ARM Mali GPU (inc Mali-200 and Mali-400)

    • freedreno: Qualcomm Adreno GPUs

    • PowerVR: Imagination PowerVR GPUs

Let's start the "Debian distro for Android capable hardware phones".

What are the first steps we can easily take, to get started on this?

1) Talk about how to do it on this email list.
2) Put something on www.debian.org web page about beginning to work on
this project.
3) Create a mailing list for "Debian for Android Hw".
4) Send some thoughts in reply to this email, & to the new mailing list.
5) Make a wiki page for "Debian distro for Android capable hardware
    - http://wiki.debian.org/DebianOnHandhelds

My motivation:  
I got an Android capable smartphone/computer a few months ago. - Samsung
Intercept, Virgin Mobil, $200, $25/month includes unlimited internet.

Of course, I'd like to get a GNU(Linux) distro on it.  So, rather than
have to piece together something using CyanogenMod & piece a bunch of
aps together, I'd just like to have a KUbuntu version to put on there. 
- Download the ISO, start, 15 minutes later it's all there with all my
familiar desktop aps in smartphone version.

So, I figure, first step (before getting my KUbuntu), is there needs to
be the Debian for Android Hw smartphones distro, for KUbuntu to build on
top of.

Ok, well, there you are, folks.  I've done my initial part for the
project - suggest it get started.  So, can some interested Debian
individuals please now step it another step forward?

Thanks for all the great Debian stuff!  :)
