[Linux] [Dev] [WIP] Ubuntu Touch on the TF101 - Alpha

[jholtom]

Hello All, I've got Ubuntu Touch compiled for our beloved TF101's.

Thread by TomTcom with instructions on how to build: http://forum.xda-developers.com/showthread.php?t=2326453 <- Same way I do it, so have at ye!

Remember this is still in Alpha on the ubuntu end, and our end too, but is still getting better, well at least ours is.

New pretty picture attached by Oeio

Instructions
- First download the latest image (below).
- Then download quantal-preinstalled-phablet-armhf.zip from here
- Place both of these files in a place where you can flash them from recovery
- Wipe data
- Then flash the ubuntu-touch-tf101.zip, and then quantal-preinstalled-phablet-armhf.zip. IN THAT ORDER
- Reboot and you should be good to go, make sure to clear cache.....
- After reboot follow the instructions in post 3 to fix the resolution, and then reboot again.

Thanks *Detection* for the screenshots and video (and onkelbebu)

Information:
- The Ubuntu Touch system is currently in developer-preview state, just to give you an idea of how incomplete this is.
- My build sources may be broken; either get along with it or wait for me to fix it.
- No longer am I the sole developer, we now have onkelbebu on board pushing changes and updating.

SOURCES
My modified device tree is here:
https://github.com/jholtom/android_device_asus_tf101
Now using this kernel
https://github.com/jholtom/kernel_asus_tf101-lumpy

Sources for Ubuntu are at:
http://phablet.ubuntu.com/gitweb


Thanks:
onkelbebu, for his help with getting wifi working, and everything else.
RaymanFX, Timduru and others for the kernel and device tree.
*Detection* for being an awesome first tester.
and of course, Canonical

Don't forget the Thanks button

Notes

1) Do not flash any other kernel with this; there are no compatible ones as of now.
2) In case you missed it: I am the official Ubuntu Touch developer responsible for the Transformer https://wiki.ubuntu.com/Touch/Devices

DEPRECATED - no longer needed as it now autofixes on first boot
Fix for the Screen Density - Copy and Pasted from the Ubuntu Wiki.

Instructions (Run from shell with transfomer connected and on.)
adb shell
ubuntu_chroot shell
vi /usr/bin/ubuntu-session

Find and edit the values for the following entries (there are two entries for each:
GRID_UNIT_PX=10 (as suggested - read below)
QTWEBKIT_DPR=1.2 (looks best to me by trial and error)



SCREEN PIXEL RATIO

We have 2 important variables that define the pixel ratio behaviour of the system and the applications, ie. how they visually scale. Look at /usr/bin/ubuntu-session for GRID_UNIT_PX and QTWEBKIT_DPR. Add another device specific settings there based on your device, using the method below to calculate the desired DPR.

The number of pixels per grid unit (GRID_UNIT_PX) is specific to each device. Its goal is to make the user interface of the system and the applications of the same perceived size regardless of the device they are displayed on. It is primarily dependent on the pixel density of the device’s screen and the distance to the screen the user is at. That second value cannot be automatically detected and is based on heuristics. We assume that tablets and laptops are the same distance and that they are held at 1.235 times the distance phones tend to be held at.

A reference device has been chosen from which we derive the pixels per grid unit for all other devices. The reference device is a laptop with a 120 ppi screen and the pixels per grid unit is set to 8 px/gu.

Asus Transformer Tablet - 1280x800 - 149 ppi - 10 px/gu

There is no way for the system to dynamically identify the correct pixel ratio for the device, which as a side effect things might be bigger/smaller than expected. For each device you will have to visually verify the quality of the result and adjust the number if necessary. If unsure, send screenshots and screen specifications of the device to the Canonical design team.

Definitely curious, appreciate the effort, but when I tested this on my GNex, I decided it wasn't quite a dayly driver thing yet. This base will be nice having once Ubuntu touch matures a bit though.

In the meantime I'll be dogfooding my own CM10.1

Before I flash this, if I make a Nandroid backup, or want to flash Android again, can I still just boot into recovery, wipe and flash as I would normally ?

Or is there something new I need to do to remove Ubuntu ?

Thanks for working on a port, really excited to see this come to our TF's

On my GNex, to get back to Android was a simple matter of restoring a Nandroid. I'm assuming it's the same here.

Great, thanks - I`ll make a Nandroid and give it a test I think then

EDIT - No boot after about 20-30 minutes

Unfortunately same thing for me. Wiped all caches, system and data. At first boot I see the Asus logo and then a blank screen. Let it sit for 10 minutes and still nothing. Will give it another hour just to be sure.

Try not to wipe system.

Install a cm10.1 based rom, let it boot, then flash both files without wiping, see if it works for you.

 

[prendomiao]

now i test it when the download finish good work and i say if something works or not ... thanks

 

[prendomiao]

guys it locks to bootanimation -_- why is the screen black????? uff..... it doesn't work, i followed the guide bit it doesn't boot

It's a first try n he hasn't tested it man... That's why. You try the no wipe method too?

~ TF101 on K900's AOKP
Currently OC'ed to 1.4, KatKernel 70

Same here. Nothing but black. No wipe? You mean flashing Ubuntu after flashing cm?

Thanks but that didn't make any difference. Oh well, I did get to play with it on a Nexus 7.

- First download this file: ubuntu-touch-tf101.zip New version is UP!

Going to give it a go as soon as I download the new image. Where are you hosting this, it's taking forever to download?

Hmm... maybe I should go and get lunch and do this later. Been 20 minutes so far for a 50MB file, Still saying 17 minutes, no wait, now its 18 minutes.

 

[jholtom]

Right now its running off of my 35mbs network connection at home...i'm getting it on a mirror right now...[2 min till mirror ready]

Is the 50MB file the only one updated?

I don't need the 480MB downloaded again ?

 

[jholtom]

yep the 50mb is the only one I change the 480mb one is updated by canonical, and is not likely to change for a while....

Don't worry, it's understandable. You did the work to port it, I don't really have any reason to ***** about waiting.
