Ubuntu Touch is an operating system for smartphones. More specifically, this is aimed at some Android devices like the Nexus 4, Nexus 7 (2013) and the Nexus 10. The Ubuntu Touch team has recently purchased the Nexus 6, Nexus 5X, and Nexus 9, so the number of supported devices will increase in the near future. In the meantime, if you want to install Ubuntu Touch on any of the currently supported devices, we have an easy guide for you.
For those wondering, yes, there is an unofficial port of the operating system for the Nexus 5. However, it is not supported by Canonical and there are some critical issues with it. For this reason, we don’t recommend trying it out at the moment.

Install Ubuntu Touch on Android devices
When Ubuntu Touch was announced initially, the installation process was quite complex. To be able to flash Ubuntu Touch on your Android device, you had to have a Ubuntu desktop as well. However, there is an easy way to install Ubuntu Touch now.
Pre-requisites
Install Synaptics Touchpad Driver Ubuntu
A supported device – Nexus 4, Nexus 7 (2013) and Nexus 10
At least 2.7 GB of free space on your device
Unlocked Bootloader
USB Debugging enabled
ADB drivers on your PC
Install Ubuntu Dual Boot app
To get started, you will have to first download and install the official Ubuntu Dual Boot app on your Android phone. The process below will reset your device so make sure you have backed up all your data beforehand.
Connect your Android device to your PC.
Download the latest dual boot installation script from here.
Now, open the terminal/command prompt and enter the following:
Once that is done, enter the following command to run the script:
Install Ubuntu Touch
Once the installation of the Ubuntu app is done, you can now proceed with the installation of Ubuntu Touch.
Open the Ubuntu Dual Boot app you just installed on your phone
Select channel by tapping on “Choose channel to install”
Select the “utopic” channel, as recommended by Canonical. Make sure you tick on the “bootstrap” option.
Tap on “Grant” when the app requests Superuser access.
Once the download is complete, tap on “Reboot to Ubuntu” to boot into Ubuntu Touch.
Ubuntu Touchpad Settings
The above-mentioned process will set up a dual boot installation comprising of Android and Ubuntu Touch. At any point, if you want to boot into Android, use the power button to reboot.

Ubuntu Touch 13.10 SAUCY Rom Triple Boot WebOS, Android, Ubuntu Touch (Or Quad if you need to) 09-27-2013 is the RootFS Date with apt-get dist-upgrade to 9-29-2013 Download Links Updated 09-29-2013 5:44 am central time http://gdurl.com/d6Qn cm-10.1-20130929-UNOFFICIAL-tenderloin.zip (Install First KernelRamdiskSystem Partition) http://gdurl.com/EnW8 saucy-preinstalled-touch-armhf.zip (Install Last Ubuntu Touch RootFSData Partition) PARTITION CREATOR AND UNINSTALLER (From ACMEInstaller3 and ACMEUninstaller) Thanks Green! http://www.gdriveurl.com/?idl=813809797536&out=2 UbuntuTouch_Partition_Creator http://www.gdriveurl.com/?idl=613809797926&out=2 UbuntuTouch_UbuntuDesktop_Partition_Creator http://www.gdriveurl.com/?idl=513809798298&out=2 UbuntuTouch_Uninstaller http://www.gdriveurl.com/?idl=413809798725&out=2 UbuntuTouch_UbuntuDesktop_Uninstaller HOW TO INSTALL! You will need a little over 2 GB of space on your sdcard to devote to the new LVM Partiitons! This assumes you HAVE installed CyanogenMod (Android), ClockworkMod Recovery, MoBoot and still have WebOS. WebOS is a prerequisite for Audio. ALSO, you need novaterm. http://www.webos-internals.org/wiki/..Using_Novaterm AND it's good to have adb as well. NOTE! If you have Ubuntu 11.04 - 13.XX Desktop Version The Ubuntu Desktop LVM needs to be Uninstalled and Recreated. I have provided uImage files and Novacom to do this, or you can change the /etc/fstab file to have the correct device mapper paritition number. Dealing with a small boot partition! It cannot hold all the uImages for WebOS, Android, Ubuntu Desktop, Ubuntu Touch, andClockworkMod at the same time. What I usually do is move the Ubuntu Touch kernel off of /boot to /sdcard (/media/internal in webos) before installing Ubuntu Touch, then move ClockworkMod to the /sdcard after installing Ubuntu Touch, and of course move the Ubuntu Desktop uImage file back to the /boot partition for Quad-Booting. You should only do this, if you know what you are doing, as having ClockworkMod on boot is handy. Know what you are doing or don't do it. (Which is why I should probably stay away from rom building!, haha) https://github.com/jshafer817/Ubuntu..data/etc/fstab *IF YOU HAVE ALREADY INSTALLED THE ROM THAT WAS NOT DUAL-BOOT CAPABLE, YOU SHOULD REINSTALL ANDROID FIRST SINCE WE WIPED IT OUT *Since we are dual-booting, we need to create 3 LVM Partitions that will use 2 GB of space from the sdcard* 1. Copy the RootFS.zip and the cm-10.zip file to the sdcard 2. Reboot into WebOS Recovery 3. novacom boot mem:// < UbuntuTouch_Partition_Creator OR novacom boot mem:// < UbuntuTouch_UbuntuDesktop_Partition_Creator (Requires 6.2 GB of Space, for Ubuntu Desktop 11.XX - 13.XX) 4. Reboot into ClockWorkMod to install the cm-10-*.zip FIRST and the RootFS zip LAST 5. Reboot and chose uImage.UbuntuTouch Wait 3 minutes, while the touchpad boots. At some point adb will start to run. Eventually you should see a Unity Session. If you didn't see a session! a) reboot! b) Eventually the backlight on the screen will shut off. Touch the screen or hit the power button or home button some builds to turn the screen on. Still no session? Can you run android-chroot when you get into adb? When you login to adb it should say [email protected] and not BusyBox? You can also run /system/bin/logcat. Hold down the power button for 2 or 3 seconds and Ubuntu Touch will shutdown. TO FORMAT UBUNTU TOUCH LVM PARTITIONS (in case your wondering create-partition.sh does this. but what if you want to format after you install to do a reinstall?? novaterm into webos! mkfs.ext4 /dev/store/ut-data mkfs.ext3 /dev/store/ut-system mkfs.ext3 /dev/store/ut-cache TO REMOVE UBUNTU TOUCH LVM's AND KERNEL novacom boot mem:// < UbuntuTouch_Uninstall TO REMOVE UBUNTU TOUCH AND UBUNTU DESKTOP LVM's AND KERNEL novacom boot mem:// < UbuntuTouch_UbuntuDesktop_Uninstall
Having problems installing WebOS Applications???? https://developer.palm.com/support/applicationupdate WebOS UpdateManager Certificate Fix http://forum.xda-developers.com/show..php?p=42317438 There is an update to WebOS. If you wipe your device after July 23rd 2013. Then you must do this. Ubuntu Touch Notes! NOTE! If you have Ubuntu 11.04-13.10 NON-TOUCH installed, you will need to: novacom boot mem:// < UbuntuTouch_UbuntuDesktop_Uninstall *Built from Milaq's CM 10.1 Source WITHOUT JCSullins Bluetooth fixes
*Bluetooth and Sound come from the Ubuntu 11.04-13.10 Non touch. Mainly the upstart and executables. WebOS does get mounted for sound to get initialized. udev and pulse were patched. *First Ubuntu Touch device running Saucy (Flipped Image) but with LVM Partitions. For this to work I had to compile lvm and e2label statically and use them in the ramdisk for Ubuntu. How Saucy Works!? Kernel is loaded with an Ubuntu Touch Ramdisk (Like normal Linux). Then the data partition is mounted as root, the system partition is mounted as /system. The LXC containter loads android based off of /system, then Ubuntu Touch Session loads. This is not a chroot like quantal. What works: *Camera *Wifi *Bluetooth *Sound *Accelerometer Bugs and BetaAlpha Stuff: 1. PulseAudioGStreamerMusic App is not tied to the Media Service, so the music does not play with the screen turned off. GStreamer keeps playing, but you cannot hear sound unless powerd has turned the screen on and. ??? Not worth changing until Ubuntu Touch becomes more. finalized. Sometimes the music does not come back on after a long sleep? Workarounds: sudo service powerd stop (with the backlight turned on) 2. Bluetooth only works in terminal a) this is because Bluetooth Settings has not been written to Ubuntu Touch 3. Camera App only works one time. Needs to be mirrored. Again. Long story! 4. Brightness or Backlight settings??? as root! echo '0-255' > /sys/class/leds/lcd-backlight/brightness to set the screen brightness. 0-255 is a range of values you should use. 0 will turn off the backlight 255 is full birghtness and of course. service powerd stop while the screen is on will stop powerd from turning off the backlight if idle. 5. Touchscreen finger liftoff does not always get detected at boot correctly. Need to talk to ubunu-devel about that.? CM-TEAM?? Hmm. Reboot and try again! 6. Browser cannot download files. Browser cannot play videos because the latest gstreamer 'has not landed yet'. 7. 720P H.264 is choppy? 480p plays fine. Waiting for more updates. APPARMOR NOTE: Since 2.6.35 Kernel does not have apparmor, we are using /usr/bin/aa-strip with crontab to run every minute. So if you install a click app and cannot run it, wait a minute! sed -i 's/aa-exec.*-- //g' /home/phablet/.local/share/applications/*.desktop OPEN-SSH NOTES: Recently they did something to openssh. Do this to install. apt-get install --reinstall openssh-server service ssh start (every boot?) If powerd turns off the backlight, it suspends your ssh session. There is some code in the wifi modules that I believe is causing it. Work on that later. or disable powerd and turn the lights off to save battery power or backlight by reading brightness notes above. MTP-SERVER NOTE mtp-server has been disabled. want to enable it? As root! cd /etc/init mv ./mtp* . cd /usr/share/upstart/sessions mv ./mpt* . reboot When you do, don't expect adb to work.. In Ubuntu 13.10 Desktop, you see the /home/phablet get Mounted on the filesystem via mtp. I haven't messed with the Windows Driver. I messed with the google one and changed the pid and vid, and. no device was found when I ran adb. so. perhaps mtp shuts down adb on the touchpad. I think that was in the upstart file though. mtp-server-bootup.conf, etc.

How do I swap my kernels to quad-boot? (With webOS) a)Before you install Ubuntu Touch, move a kernel from /boot to /media/internal novaterm mount -o remount,rw /boot mv /boot/uImage.Ubuntu13 /media/internal (or uImage.Ubuntu) mount -o remount,rw /boot b) After you install Ubuntu Touch, move it back, but remove ClockworkMod (know what you are doing are don't do this) novaterm mount -o remount,rw /boot mv /boot/uImage.ClockworkMod /media/internal mv /media/internal/uImage.Ubuntu13 /boot sync mount -o remount,ro /boot How can I run webOS Doctor after all this and just start all over factory clean? http://forum.xda-developers.com/show..php?t=1564938 3rd post but I would skip the creation of /dev/store/cm-* partitions. Be sure to delete cm-data, cm-system, cm-cache, ut-data, ut-system, ut-cache, and ubuntu-store if you have it. Delete them all! Then recreate the lvm. If you need to recreate Android partitions do that with AcmeInstaller ie the usual way to install Android. You must start with WebOS 3.0.0 and then you can do 3.0.5. Be sure to say thanks on that post.
