HOW TO: Set up the HP TX2z and Dell XT & XT2 (N-trig digitizer) in Ubuntu

[fa225909]

by the way, I lost sound ....

okay, I replaced event8 by event7, as a result that I get my cursor to go on the left-top corner of the screen (next to the Ubuntu symbol), it's the point (0,0) I think

Based on this info, it looks like /dev/input/event9. At what point did you lose sound?

[Nphyx]

I got rafiyr's drivers working with hal instead of xorg.conf. Here's all the info:

Kernel: 2.6.31-19-generic
Architecture86_64
Distro: Kubuntu 9.10
N-Trig firmware: Vista/factory default

Steps:

• remove/comment out file at /usr/share/hal/fdi/policy/20thirdparty/11-x11-synaptics.fdi
  
• leave your 10-linuxwacom.fdi in the same place alone if it's recent, otherwise remove it as well if it contains N-Trig lines
  
• create 10-ntrig.fdi and fill it with the following:
  

  <deviceinfo version="0.2">
    <!-- N-Trig Duosense Electromagnetic Digitizer -->
    <device>
      <match key="info.product" contains="N-Trig Pen">
         <merge key="input.x11_driver" type="string">wacom</merge>
         <merge key="input.x11_options.Type" type="string">stylus</merge>
         <merge key="input.x11_options.Button2" type="string">3</merge>
      </match>
      <match key="info.product" contains="N-Trig">
         <match key="info.capabilities" contains="input.touchpad">
          <merge key="input.x11_driver" type="string">wacom</merge>
          <merge key="input.x11_options.Type" type="string">touch</merge>
          <merge key="input.x11_options.Touch" type="string">on</merge>
         </match>
      </match>
    </device>
  </deviceinfo>

• Revert your xorg.conf to the one that fglrx generates automatically, or if you have other config info in there just delete all devices & entries in ServerLayout related to your touchscreen.
  
• Reboot/restart hal service & Xorg, it should work (at least it did for me).

-----
Notes for Ayuthia/Rafyir/anyone interested:


I used info.capabilities in 10-ntrig.fdi instead of explicitly matching Touchscreen, which for some reason seemed to work better (and *hopefully* it will work with the MultiTouch device as well, which my firmware doesn't show).

I *tried* to get the synaptics fdi to exclude n-trig devices using a not_contains match to no avail, I may have written it wrong, so I just axed the file instead. I may need it back at some point, but atm I don't care.

Some strange things that still don't add up for me:

$xsetwacom list dev
CNF8038     stylus

There's that strange CNF8038 device again, and "touch" isn't listed as it was when using xorg.conf.

Regarding the event numbers shifting around when I removed / added USB devices, I did find a way to get udev to reliably map them to a symlink instead of relying on eventXX. The trouble is xorg.conf didn't want to play with them. I confirmed that they were getting mapped properly using udevadm info but the second device linked was always ignored. Here's the rule I made if anyone wants to play around with the idea:

# Link N-trig USB tablet to unique inputs for rafiyr's split devs
SUBSYSTEMS=="input", ATTRS{name}=="N-Trig Touchscreen", ATTRS{phys}=="*input0", SYMLINK="input/n-trig-touchscreen"
SUBSYSTEMS=="input", ATTRS{name}=="N-Trig Pen", ATTRS{phys}=="*input0", SYMLINK="input/n-trig-pen"

Last but not least, xsetwacom still won't set stylus rotation correctly.

Edit: Oh thanks for that lshal script btw, helped a lot in figuring out what was going on while I was experimenting.

[fa225909]

I don't know, I haven't listened anything today, I just noticed that I didn't hear the "tam-tam" at ubuntu starting

It isn't that bad, I prefer getting the touch working without sound than no touch with sound ...

[fa225909]

I modified my xorg.conf and now the stylus doesn't work anymore !! (no touch also)

[fa225909]

I tried to modify the xorg.conf (event9 to event7) but it doesn't work ....

Do you have an idea ?

[fa225909]

anyone ?

[Ayuthia]

I tried to modify the xorg.conf (event9 to event7) but it doesn't work ....

Do you have an idea ?

Try using the attached xorg.conf file. Make a backup of your original file first:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.ubuntu_backup

Then copy the attached xorg.conf file:

sudo cp xorg.conf /etc/X11/

This one is going to use the wacom module. Have you compiled an installed the patched wacom driver yet? I just realized that the ntrig driver that you are trying to use has not been tested with the new kernel changes that Rafi Rubin provided so that would explain why the cursor jumped to (0,0) when you changed it over to event7.

If you have not compiled a patched wacom driver yet, you can use the following:

cd
wget http://kernel.ubuntu.com/git-repos/ubuntu/linux-2.6/drivers/hid/hid-ids.h
sudo cp hid-ids.h /lib/modules/$(uname -r)/build/drivers/hid/
wget http://linuxfans.keryxproject.org/packages/experimental/wacom/ntrig/linuxwacom-0.8.5-9-ntrig.tar.bz2
tar -xvjf linuxwacom-0.8.5-9-ntrig.tar.bz2
cd linuxwacom-0.8.5-9
make clean
./configure --enable-wacom --prefix=/usr
make
sudo make install

Please try this along with the attached xorg.conf file and restart. In theory, it should work.

EDIT: Instead of the attached xorg.conf, please download it here.

[fa225909]

Hmm .... You'll probably think I'm stupid but .... where is the attached xorg.conf ??

EDIT: Do you mean the one attached in the first post ?
