Linux on Pixel C : Running ubuntu xenial in a LXC container

Hi guys,

Today i wanted to share with you some of my work to run linux on the pixel C. :D

First of all i'm not responsible for anything, so try this but i can't guarantee that it works for you and that you won't break your tablet (even though normally it should work ;) ).
Secondly this thread is for people who know how to use correctly adb, fastboot and linux console, instructions are not very detailed here, so if you're stuck try a bit to search, you will learn a lot !

So first what is LXC ?

LXC (Linux Containers) is an operating-system-level virtualization method for running multiple isolated Linux systems (containers) on a control host using a single Linux kernel. (wikipedia)

We are gonna use this technology to run ubuntu on Pixel C (we will even be able to access to the GPU drivers in the future, i'm currently working on it)

I developped all of this on DP4, so please update to the lastest android ! (I will give kernel for 6.X devices in the future).

So first, we need a special kernel where cgroups are activated.

Please download an flash my modified XCeed kernel on DP4 :

Code:

---

fastboot flash boot boot.img

---

Try to see if you can run su in the tablet, otherwise you will have to install supersu.

Now, install busybox so that we have some tools to help us a bit : https://play.google.com/store/apps/d....busybox&hl=fr :)

Download now lxc compiled with PIE support for Pixel C and the ubuntu rootfs (here is a 32bit version, 64bit is also working fine on my tablet :) ) :
https://drive.google.com/open?id=0Bz...nJBbS1LbGo0MUE

send it to the pixel C :

Code:

---

adb push lxc.tar.gz /sdcard/

---

Now extract the archive in /data

Code:

---

adb shell
su
tar xvzf /sdcard/lxc2.tar.gz -C /data/

---

Now run ubuntu and enjoy ! :highfive:

Code:

---

# open a terminal as root on the tablet
# execute :
/data/lxc/startSystem

---

If everything goes well, you will see ubuntu booting ;)

Internet will work out of box if your tablet has a net access, you can install, remove things using apt :)

What is going on for this project :
I'm currently trying to use the GPU drivers using libhybris so that in the future we can run wayland on pixel C and have a fully working linux environnement ! (KDE, gnome)
see here for KDE, we need to port this : http://blog.bshah.in/2016/05/02/plas...w-base-system/
I need help for this (because it's difficult). For this, we will have to patch bionic so that we can use libhybris. All the devs can contribute here :))

If you're happy of this work and you want to have more detailed instructions please pay me a beer ! Because developing for Pixel C is time consuming ;)
