Ubuntu Phone for Nexus One brought to you by Evervolv

Prereq:
Sdcard with sd-ext part. i.e. A second partition formated as ext4 and AT LEAST 1.5GB FREE space
Micro sdcard reader for pc.
Linux pc with sudo access. NO WINDOWS PCs
Will work on any hboot (including stock)
Click to expand...
Click to collapse

Intro:
Ubuntu is ~1GB so we must install to the sdcard. Instead of ****ing with a2sd
I have just modified the ramdisk to mount mmcblk0p2 (sdcard second partition)
directly to /data. The 'copy-tarball' script will push the ubuntu rootfs to the
proper location which is mounted as /data/ubuntu. The perms on this folder must
be correct or it will not boot, therefore no windows (unless someone gets it
working).
Click to expand...
Click to collapse

How it works:
Ubuntu did a fantastic job making this easy. Essentially all that is happening
is it boots android sans gui. During the bootup a service called ubuntu_chroot
runs which exports some vars, bind mounts some things, then chroots /data/ubuntu
and starts the ubuntu init process. From there the prebuilt ubuntu takes off.

Building:
The android side is now based on Evervolv v3.2.0 every device we support
can run ubuntu with minor changes.
to get source:
Code: 
repo init -u git://github.com/Evervolv/android.git -b jellybean-ubuntuphone
repo sync
Click to expand...
Click to collapse

Whats working:
Wifi, Browser, THAT IS IT. It is slow, very very alpha.
Only install if you are curious.
Click to expand...
Click to collapse

Install:
---Download:
Grap the latest installer script, and android image from http://archive.evervolv.com/ubuntuphone/
Ive also uploaded the ubuntu rootfs i used to test it, you can try the latest nightlies but if they dont work download the latest ubuntu rootfs from above url
Click to expand...
Click to collapse

---Insert sdcard and mount
Most distros will automount. In that case just figure out what folder its in
e.g. /run/media/drew/blablabla
If not just open in in nautilus and figure out what folder its in.
Click to expand...
Click to collapse

---Unzip installer tools
Code: 
$ cd ~/Downloads
$ unzip ev-nexusone-ubuntu-tools-1.zip
$ cd ev-nexusone-ubuntu-tools

---Copy the ubuntu rootfs to sdcard
Code: 
# adjust paths accordingly.
$ bash copy-tarball.sh quantal-preinstalled-phablet-armhf.zip /run/media/drew/blablabla

---Install android images
like any other rom, fastboot update package and flashable zip available
no wipe needed
Click to expand...
Click to collapse

---Bootup
There is no bootanimation, just black screen. It might take up to 5 minutes to boot ubuntu. If you think it is stuck. Check logcat and dmesg
$ adb logcat -C
->> check for repeating errors
$ adb shell dmesg
->> check repeating errors e.g.
<6>[ 181.698364] init: ubuntu-session state changed from starting to pre-start
<6>[ 181.698608] init: ubuntu-session state changed from pre-start to spawned
<6>[ 181.715667] init: ubuntu-session main process (724)
<6>[ 181.716003] init: ubuntu-session state changed from spawned to post-start
<6>[ 181.716583] init: ubuntu-session state changed from post-start to running
post full logcat and dmesg
Click to expand...
Click to collapse

---Once booted
Code: 
#swipe right to unlock
#drag down on network icon and connect to network (confirmed wpa2 personal works)
#use adb to set timezone and install ssh
$ adb shell
root@android:/ # ubuntu_chroot shell
#change to yours
root@localhost:/# echo "America/Chicago" > /etc/timezone
root@localhost:/# dpkg-reconfigure --frontend noninteractive tzdata
root@localhost:/# apt-get update
root@localhost:/# apt-get install openssh-server
# set reasonable hostname
root@localhost:/# echo n1 > /etc/hostname
# get out and reboot
root@localhost:/# exit
root@android:/ # exit
$ adb reboot
# do NOT reboot from within ubuntu chroot you must reboot from android
#connect ssh password phablet
ssh phablet@n1
enjoy full command line goodness on your phone
phablet@n1:~$ lsb_release --all
    No LSB modules are available.
    Distributor ID:	Ubuntu
    Description:	Ubuntu 12.10
    Release:	    12.10
    Codename:	    quantal
phablet@n1:~$ uname -a
    Linux n1 2.6.38.8-evervolv-perdo-jellybean #1 PREEMPT Sun Feb 24 16:34:07 CST 2013 armv7l armv7l armv7l GNU/Linux

---Navigation
Softbuttons (home/menu/back/search) dont work and wont. ubuntu is swipe based and these would only inhibit usage
swipe up from bottom to get to app specific menu
swipe up from bottom to about halfway up screen untill you see the button (see last screenshot) to get to main menu (where you can close apps)
Click to expand...
Click to collapse

---Caveats
Allways keep it plugged in. There is no power management
Screen stays on all the time, and there is no way to turn off the device
except through adb.
Click to expand...
Click to collapse

To get back to regular android
boot recovery and run nandroid or flash latest evervolv nightly (or whatever)
Click to expand...
Click to collapse

Superb!

Just when I thought that 4.2.1 is going to be the last flavor of Android I flash on my beloved N1, along comes texasice with a Ubuntu flavor.

Thanks a lot man! You rock!

Once ubuntu gets it more stable we'll post a custom ubuntu rootfs that can be flashed directly from recovery ( the *phablet*.zip is flashable but can only be used on devices with enough space on /data) For now you can probably modify the updater-script to install to /sd-ext/ubuntu if you dont have linux.

Re: [N1][DEV] UbuntuPhone {EXP}

Is ubuntu supposed to be less power hungry than JB or is exactly the same? Is it going to run fast on old phones?
I have my old nexus one and would love to revive it but JB is too buggy and power hungry for the n1.

    Display is working again...

    Get the new android img:

    Get the new installer package:

    Get the latest raring release: (i tested with the 4/24 build, if the latest is broked again.. try this)

    And run the installer.

    just a note. it is no more usable now that it was for the mwc demo. they still need time to get it working, like i said before probably early 2014.
