I think I have the right alsa setup but I could be wrong...

edit --- I did more messing in alsa and now audio works =)

Hi zachf714,

I have similar problem. How did you solve yours.

Thanks

I actually found the root of the problem yesterday ..the DCR option is unticked by default and that breaks audio

New Ubuntu 14.04 image for rootbind with graphics acceleration

Hi all

I present to you you a fully working image of Ubuntu 14.04 with working Nvidia drivers.
This is KDE (kde-plasma-desktop) as this is what I am using. It is a minimal installation with only the basic stuff to get a working desktop - the rest you will have to install yourself. You should be able to install other desktops (lubuntu, etc.) and I see no reason why they would not work.

Default user: tf101 (has sudo privileges)
Password: ubuntu

Features:

Created from scratch using debootstrap (not via upgrade!). No more kernel panics!
Nvidia graphics drivers working. This took quite a bit of work and requires the raring, saucy and trusty releases to be enabled in your sources.list. I attach my /etc/apt/preferences.d/xserver.pref file with the pinning details, in case anyone wants to try for themselves. This is using the X-ABI 13 drivers (from 13.04) which work well as mentioned previously.
KDE graphics accelleration and desktop effects with kwin_gles. es2gears gives 300-320 fps.
Zram enabled (configure in /etc/init/zramswap.conf)
Touchegg (multi-touch screen gestures) installed and set up.
Kernel modules for all my rootbind kernels pre-installed and set up. Works (tested) with 3.1.10-9 and 3.1.10-12 kernels. Should work with 3.1.10-10 also. Take your pick
Time zone and locale set to South Africa (change in KDE systemsettings or with sudo dpkg-reconfigure tzdata).
Convenience scripts (in /usr/local/bin):
- wifitoggle
- bluetoothtoggle (disconnect all BT devices before switching off, otherwise system freezes)
- touchpadtoggle
- touchscreentoggle
- fixlidclose.py (loaded automatically on KDE start, switches screen and touchpad off properly when lid is closed, and reactivates when lid is opened)
Key bindings (using the "Home" key next to the left Fn key in the bottom row of the dock, referring to Android shortcut keys in top row):
- Home-F1 - wifitoggle
- Home-F2 - bluetoothtoggle
- Home-F3 - touchpadtoggle
- Home-F4 - screen brightness down
- Home-F5 - screen brightness up
- Home-F6 - touchscreentoggle
- Home-F9 - systemsettings
- Lock (top row right) - multi_key (Unix compose key for making accented characters)
- Right-Alt - Insert
- Menu (next to Right-Alt) - Delete

Bugs:
Some KDE plasma widgets do not respond to mouse input. Amongst these is the KDE Network Management widget, unfortunately. Either configure your wifi from the command line using nmcli or use another network manager such as Wicd (not tested). Once your network is set up, the wifi should reconnect automatically though.

Thumbs up !

Thanks for your work, pretty amazing.

I think I'll try to install Plasma Active, maybe it can work great now. Could be cool to try.

Thanks for that, at least I know I'm not doing something wrong my end, I was trying the Ubuntu 12.04 netinstall from the Transformazing thread, I`ll no doubt try a few until I find one I like

I don't have a Linux box atm, but a quick fix with a wubi or VM install tomorrow and I`ll give your method a shot

Cheers

A little question @jrohwer, do you think change root=/dev/mmcblk0p7 bind=/linuxroot by root=/dev/mmcblk1p1 bind=/linuxroot to get it booting from SDcard, is possible ?

Or there is a problem with file system and or mounting process ? The SDcard must be ext4/2 ?

( I'm adding how to change location in my guide )

Don't waste your time with plasma active, unfortunately it doesn't work

It's one of the first things I tried after I got KDE running on my TF. It has to do with the fact that the plasma widgets do not respond to mouse action for some reason. Also KDE "activities" don't work. And it is the same reason that the network management widget does now not work on 14.04 (see above). It is a real pity as I think the kde-plasma-netbook interface would have been absolutely brilliant for our TF101, but unfortunately it does not work.

Why do you want to use bind mount on the external SD card? You can just make a second partition (/dev/mmcblk1p2) and format it ext4 and then unpack the filesystem to there. Then your kernel command line is simply root=/dev/mmcblk1p2 (no bind argument). I guess if you formatted /dev/mmcblk1p1 to ext4 and then made a linuxroot folder in there, it could work but why would you want to do that?
The file system definitely has to be ext2/4 or something POSIX compliant, so vfat won't work. I am not sure how android copes with ext4 formatted SD cards.

EDIT: By the way I get it working perfectly from a second ext4 partition on my SD (/dev/mmcblk1p2). In fact on my SD I have a barebones installation (just command line) which I can boot up for debugging/system rescue purposes. Much more powerful than going through adb shell in recovery.

Ho yeah I see, that was the problem when I tried it last time.

I think it comes from the video driver. I cant really tell why but I got a similar problem with my PC. I have sometimes click missing on some object ( It select it instead of click like it can do with touchscreen on our TF ) and if I install video driver it's even worse and unusable. It's maybe not really the video driver itself, but it's linked with I think.

I asked this cause someone asked to do that lol.
But yeah of course, a dedicated partition is definitively better choice.

And having a backup system on sdcard, is a brilliant idea !

Thanks a lot for those informations

another method to get it working? http://xdaforums.com/attachment.php?attachmentid=2737523&stc=1&d=1399801979 here, this task manager (or if it is a task manager integrated in the desktop) what is the name of it? (PS: sorry for there names but i'm noob about ubuntu XD)

---------- Post added at 05:30 PM ---------- Previous post was at 04:57 PM ----------

there are too much problems :/ the desktop home doesn't work well, the cursor is laggy and loading animation is broken... the keyboard has problem with touchpad (with a delay), touchscreen works only as a touch-friendly cursor (double click doesn't work as one-click; is it an ubuntu problem?) and without keyboard the os doesn't start

( nice but with problems... is ther another ubuntu version stable or more working?

if you need test, i have an empty tablet, i don't use it a lot XD

Download links to my Ubuntu 14.04 image from post 303 removed for the time being. There seems to be a problem in that it does not boot up. Need to debug this first and will post here again if it is working.

Got side tracked on building the lubuntu IMG.. But been banging my head on the sound problems

I want to trouble shoot it with a USB audio stick. Problem! Kernel does not support USB audio... No problem.. I will build the modules, build them and modprobe them in.. But no love.. I can't them them to load version magic matches and everything.. I was able to get the dm9061 loaded the same wayaybe audio is more kernel dependent

I went as far as building a whole new kernel off sni's .config with your source.. Added in the rootbind in the image.cfg but the bloody thing kernel panic ed !! Can't win!

Next I will try to build without changing the modules and keep it clean to see if it will post.. I am working off the tf101 wiki on xda for Ubuntu kernel building ..

Oh the pain in my head, lucky I like a challenge!

Oh! On a side note: I tested more hardware over USB.. The Logitech C110 works like a charm! So if anyone wants video go pickup one of those, cheap as chips and work! - maybe one day we will get the onboard cam working

Did you change the kernel source or only the config? If you only changed the config you could post it here and then I could try to compile it on my side as well....

OK well good news.. I have not fixed the sound issue yet! But now we can play back DVD's on the TF101 (see attached)

USB DVD SUPPORT

One of my goals was to get DVD and CD play back and writting
If you plug in a USB dvd / cd then you can use it.. Only for rootbind kernel 10.12 OC

See attached

I will add things like this to the builds too!

DVD playback is not good.. Laggy .. VOB transcoding is the problem..
If you want to give it a crack you will have to get the DVD decoding libs too:

sudo apt-get install libdvdread4
then install the deb attached dpkg -i .. its the other dvd coding lib that is required.. then you will be able to open using mplayer / gnome-mplayer.. VLC was crashing for me.. smplayer worked really well still laggy but would play

So what else I tested.. Opening files and burning:

Xfburn worked fine ::

Things that you need to do if you want to burn / play back dvd etc
(each time the dvd player is plugged in)

sudo chmod 777 /dev/dvd
sudo chmod 777 /dev/sg0

I use a Samsung usb dvd rw player.. works fine was about $20 AUD

DEB was from here: http://www.deb-multimedia.org/dists/testing/main/binary-armhf/package/libdvdcss2
Used parts of this guide to get the support working after lots of head banging :

Full of good news tonight

OK I got a working USB audio module see attached .. Not really applicable unless you have a USB audio key stick etc..
I am going to use this to debug sound issues with the kernel / images

Might be hard to see but thats ALSAmixer with the key

I packed everything from the /kernel/sound folder.. But I think we only need kernel/sound/usb - and maybe core.. can't be sure.. until i rebuild

win! - two goals smashed in one night

Oh i am using a creative sb1140 that I bought just for this debugging..

If you are on clean build to debug things. What do you think about making a diff of 2 versions with bs diff for exemple and make a recovery zip that patch files may avoid reinstalling everything for a patch?

I've made a program on Windows to make my Nexus 4 rom OTA. It may be adaptable to this case.

What do you think about that?

I'll maybe try to adapt it when you'll release a new build to see how it goes.

I like the idea of zip flashing.. But what about pure OTA? having a script that checked for chages from GIT or something then just patches the required files.. IE like if we get audio working correctly just changes the audio config files to fix them.. ETC..

I think linux might be harder to patch via zip then Android?
