Ubuntu 14.04 Trusty Tahr Support

I too am having trouble. I downloaded the 64 bit nwfermi drivers located here:
https://launchpad.net/nwfermi
Version 0.6.5.0

Trying to install I get a failed dependency:
ia32-libs

I read and found out that package is depricated, so I repackaged the .deb file as suggested here: http://askubuntu.com/questions/107230/what-happened-to-the-ia32-libs-package

Now I get another failed dependency:
xf86-input-nextwindow

That's even after adding the repository: ppa:djpnewton/xf86-input-nextwindow

When I do the apt-get update, it fails to download the index files, so it may no longer be available.

So... I browsed to the URL listed in the error messages: http://ppa.launchpad.net/djpnewton/xf86-input-nextwindow/ubuntu/dists/

And I see that precise is the last directory there, so I edited /etc/apt/sources.list.d/djpnewton-xf86-input-nextwindow-trusty.list and changed the trusty to precise and that got the package installed.

So... after giving me a warning that the package was of low quality, I now have nwfermi installed.. I am going to reboot and see if it works...

Chris did you get it to work?

I get it to work on 14.04 amd64.

Download https://launchpad.net/nwfermi/trunk/0.6.5/+download/nwfermi-0.6.5.0_amd64.deb

mkdir nwfermi_temp
dpkg-deb -x nwfermi-0.6.5.0_amd64.deb nwfermi_temp
dpkg-deb --control nwfermi-0.6.5.0_amd64.deb nwfermi_temp/DEBIAN

gedit nwfermi_temp/DEBIAN/control
and replace ia32libs
 with
 lib32z1, lib32ncurses5, lib32bz2-1.0

gedit nwfermi/usr/src/nwfermi-0.6.5.0
I replaced all occurances of function err with pr_err.
I replaced dbg function on line 503 with

printk(KERN_DEBUG "URB Status: %d\n", urb->status);

Rebuild package:
mkdir nwfermi_new_package
dpkg -b nwfermi nwfermi_new_package/nwfermi-0.6.5.0_amd64.deb

Followed this guide for xf86-input-nextwindow:
http://tangopardo.com.ar/2cf7/2013/07/27/installing-a-nextwindow-fermi-touchscreen-under-ubuntu-13-04-raring

My modifications:
apt-add-repository ppa:djpnewton/xf86-input-nextwindow
sudo gedit /etc/apt/sources.list.d/djpnewton-xf86-input-nextwindow-trusty.list

in this file I replaced trusty with precise as trusty is not yet supported so it look like this:

deb http://ppa.launchpad.net/djpnewton/xf86-input-nextwindow/ubuntu precise main
deb-src http://ppa.launchpad.net/djpnewton/xf86-input-nextwindow/ubuntu precise main

sudo apt-get install build-essential autoconf2.13 xorg-dev xserver-xorg-dev xutils-dev libtool debhelper
apt-get source xf86-input-nextwindow
gedit xf86-input-nextwindow-0.3.4~precise1/debian/control

replaced libutouch-grail-dev (>= 1.0.10) with libgrail-dev
cd xf86-input-nextwindow-0.3.4~precise1
fakeroot dpkg-buildpackage
cd ..
sudo dpkg -i xf86-input-nextwindow_0.3.4~precise1_amd64.deb
dpkg -i nwfermi_new_package/nwfermi-0.6.5.0_amd64.deb

Pointer is working, but 2-finger touch is not. Any suggestions?

Hello I didnt get it to work yet but I will try the above when I have time but on www.nextwindow.com there are newer drivers nw-fermi 0.7.2.0 if I'm correct maybe multi touch works then. hope it helps

Tried nw_fermi 0.7.2.0 but multitouch is not working (tried with ginn and touchegg in Ubuntu Unity and Gnome3 Shell). Driver still needs to be rebuild in 14.04 but without code replacement.

Maybe the problem is with xf86-input-nextwindow and not with kernel driver.

I try your procedure ales-hribar

but into last step, I get the following error:

Unpacking nwfermi (0.6.5.0) over (0.6.5.0) ...
dpkg: dependency problems prevent configuration of nwfermi:
 nwfermi depends on lib32z1; however:
  Package lib32z1 is not installed.
 nwfermi depends on lib32ncurses5; however:
  Package lib32ncurses5 is not installed.
 nwfermi depends on lib32bz2-1.0; however:
  Package lib32bz2-1.0 is not installed.

Can some one help me?

I think that the solution is a big workaround, for a definite solution. Will be great if the develop of this driver get support to the Ubuntu 14.04 LTS 64 bits.

Thanks

This is the complete procedure, that I follow and get working successfully!!! I add some steps and correction to the previous procedure.

1. Download https://launchpad.net/nwfermi/trunk/0.6.5/+download/nwfermi-0.6.5.0_amd64.deb

2. mkdir nwfermi_temp
3. dpkg-deb -x nwfermi-0.6.5.0_amd64.deb nwfermi_temp

23. dpkg -i nwfermi_new_package/nwfermi-0.6.5.0_amd64.deb

I also got it working using aleshribar post but only single touch.
Andres do you have multi touch or just single?

Only single touch :( with a lot of workaround...

Can you help me plz? I am not guru like you! :)

I followed Anders' steps. I got it installed, rebooted but still no touch i put.
What am i missing? I checked the /dev/input/event3 and it gets the input from the screen.
How can i help you help me?? :) :) (if you want !!!)

Manolis do you have 64-bit or 32-bit instalation of Ubuntu? These steps here are for 64-bit only. Anyway, If you get events from screen and not cursor actualy moving, you have kernel module working (nwfermi package) and xserver input driver not working. I recommend you to check /var/log/Xorg.0.log for more details.

64-bit. Yes it seems like it is installed.
Can you take a look at my Xorg? I can see the problem at the log but i do not really know how to fix it :(
Again, thanx for your time for sharing this info!!

https://drive.google.com/file/d/0B0Ti0yc8B-GjZGFRY0ZUanFPaVE/edit?usp=sharing

This is the quick method with custom packages modified by me:

1.- Download the modified packages: https://mega.co.nz/#!xIVzzCiQ!cCh1yyLq8nllHJ4-dtSwqQIVqmJ4leJ9cTm3sZPW1-c
2. sudo apt-get install build-essential autoconf2.13 xorg-dev xserver-xorg-dev xutils-dev libtool debhelper
3. sudo dpkg --add-architecture i386
4. sudo apt-get update
5. sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 libc6-i386 lib32tinfo5 libc6-i386
6. sudo dpkg -i xf86-input-nextwindow_0.3.4~precise1_amd64.deb
7. sudo dpkg -i nwfermi-0.6.5.0_amd64.deb
8. reboot

Working successfully with Ubuntu 14.04 LTS 64 bits (clean installation) and HP TouchSmart 520-1060.

Enjoy

Manolis this is the problem:

[ 5128.734] (EE) module ABI major version (16) doesn't match the server's version (20)

you have to rebuild xf86-input-nextwindow if you haven't follow Andres' latest comment. Yo have installed version from ppa and not your rebuild version.

Here are better instruction for building xf86-input-nextwindow:

1 -8 same as Anders' solution.
9. apt-add-repository ppa:djpnewton/xf86-input-nextwindow
10.sudo gedit /etc/apt/sources.list.d/djpnewton-xf86-input-nextwindow-trusty.list
11.Replace trusty with precise as trusty is not yet supported so it look exactly like this:

deb http://ppa.launchpad.net/djpnewton/xf86-input-nextwindow/ubuntu precise main

 -- Ales Hribar <email address hidden> Mon, 12 May 2014 12:30:00 +1200

16a. gedit xf86-input-nextwindow-0.3.4~trusty1/debian/control
16b. replaced "libutouch-grail-dev (>= 1.0.10)" with "libgrail-dev"
17. cd xf86-input-nextwindow-0.3.4~trusty1
17. sudo dpkg-buildpackage -d

23. sudo dpkg -i nwfermi_new_package/nwfermi-0.6.5.0_amd64.deb

 Make sure you disable the repository after you build xf86-input-nextwindow:

sudo gedit /etc/apt/sources.list.d/djpnewton-xf86-input-nextwindow-trusty.list

and add # before every line so it NOW looks exactly like this:

# deb http://ppa.launchpad.net/djpnewton/xf86-input-nextwindow/ubuntu precise main
# deb-src http://ppa.launchpad.net/djpnewton/xf86-input-nextwindow/ubuntu precise main

then run

sudo apt-get update

and make sure that

sudo apt-get upgrade

doesn't list xf86-input-nextwindow among upgradeable packages.

Finall, run:

 sudo dpkg -i xf86-input-nextwindow_0.3.4~trusty1_amd64.deb

and test that everything is correct again with

sudo apt-get update
sudo apt-get upgrade

the last command should NOT upgrade xf86-input-nextwindow package.

I have also build i386 packages. They too work, but no 2-finger touch. If anyone is having problem with i386 distro, let me know.

it worked. Thanx both of you guys!

Just for the history, what I did wrong is that after all the steps above, i apt-get upgrade again, so the package from repository was installed in place of the modified package. Disabling the repository was the trick.

Thanx again everyone

Congratulations manolis!!!

Can someone please do a recapitulation of the actions required to get this touchscreen of the Asus ET 2410 All-in-One computer to work please ?!

On beforehand many Thanks !!!!

Hopefully someone can help.

I am running Ubuntu 14.04 x64

I have followed each tutorial listed here more than once, and even tried mixing and matching.

Still no touching :(

It seems like I'm close, but when I run nwfermi-0.6.5.0_amd64.deb, I get

Error! Bad return status for module build on kernel: 3.13.0-39-generic (x86_64)
Consult /var/lib/dkms/nwfermi/0.6.5.0/build/make.log for more information.

I tried to "consult the make.log" and I had no idea what I was looking at.

Am I missing something?

Please, feel free to call me an idiot if I am.
:)

Running 14.04lts 32-bit

xorg.0.log give this well known error:
module ABI major version (16) doesn't match the server's version (20)

Can someone help med with a tutorial for i386?

Regards
Kjartan

Andres Natanael Soria (andresnatanael)

Holy crap!!!

Thank you.

Messed with this on and off for YEARS.

Tried all the complicated stuff, and in the end your "quick method" from post #13 did the trick.

I am saving your custom packages to my server, flash drive, dvds, emailing it to myself, etc.
I never want to lose this.

I had everything working in older Ubuntu's, but was always a pain, then nothing for years.

Now I just need to copy and paste a few lines, and BOOM!

Thank you very very much.

If you're ever in the Chicagoland area, I owe you a beer, monster, redbull, mt dew, or whatever.

Thank you all for sharing this. I made it work in Ubuntu 14.04.

Now I'm using new Ubuntu 15.10, and I cannot figure out how to make it work again. It seems the nwfermi package published here has some kind of "incompatibility" with the new kernel... maybe just something to fix in the code, but don't know where and what...

Can someone give me some help?

Thank you

Hi Guys.
My pacient is Sony Vaio VPCL12M1E, tried to make it play on a clean Ubuntu 16.04 without any luck :(
Went through everything what was available over the web in this matter.

It didn't worked with any kernel (4.4.0-31-generic or 4.4.0-38-generic).

My procedure was almost same as described above with some slight mods.

1. Recompiled kernel module as described above, with dependencies: libz1:i386, libncurses5:i386, libbz2-1.0:i386, xf86-input-nextwindow
2. FIxed unknown keys in /etc/udev/rules.d/40-nw-fermi.rules by replacing SYSFS with ATTRS

Xorg also didn't complained about the driver, but...

Catting the /dev/input/event6 is always empty.
Also nothing in /dev/hidraw1
But on the other hand /dev/nwfermi1 sings loud with loads of binary data.

Tried many different solutions and none of them made nwfermi driver to send input events.
I'm pretty fresh linux user and have very little experience with hardware and X.org server.
Can anybody please spread some light on this one ?

Thank You!

Lucas

Here we are again. :(

The solution from post #13 looks like it almost works in 16.04.

It gets hung up on lib32bz2-1.0 which I assume doesn't exist in 16.04 ?

Has anyone had any luck?

Total noob here trying to do this on 16.04 and essentially fumbling in absolute darkness

With lots of googling I managed to get the package installed without errors but it's not actually working.

What I did:
Downloaded the modified packages from #13
Changed lib32bz2-1.0 to libbz2-1.0:i386 in nwfermi_temp/DEBIAN/control
Added #include <linux/uaccess.h> to fermi.c (I was getting an "implicit declaration of function copy_to_user" and "copy_from_user")
Rebuilt the package
Followed the procedure in #13, changing lib32bz2-1.0 to libbz2-1.0:i386 in line 5
I also needed to install dkms (sudo apt-get install dkms)

Doing that I can get through the whole procedure in #13 without errors however the touchscreen is still not working after reboot. Meaning in touch the screen and nothing happens except me leaving fingerprints. I must be missing something that is so obvious it is not stated on this page. Any ideas?

Doing this on a HP Compaq Elite 8300 All in One Touch, dual boot Ubuntu/Windows 10. The touchscreen works fine under Windows 10.
