Ok. Looks like the upstream wacom .fdi file doesn't know it yet. According to Google it's some wacom Tablet PC.

--> http://goatonabicycle.com/rambles/?p=74

Hope this helps.

You're right. SaX2 does not support the configuration of it and this won't change
unless we receive a request by HP to do so + the appropriate hardware for testing.
WONTFIX.

Sax2 step is the last step but a required step to get laptops with n-trig touchscreens to works with OpenSuSE. Please take a look to http://en.opensuse.org/SDB:Howto_install_OpenSuSE_on_HP_tx2-xxxx_laptops

And to these bug : https://bugzilla.novell.com/show_bug.cgi?id=548463

When it will be fixed, and after patched linuxwacom driver installation, the last step remain this sax2 entry.

Experienced users will setup manually their xorg.conf, but for newbies, it's a blocking critical bug. So I think it must be re-opened.

So without patching our kernel and wacom X driver first, it won't help to adjust sax2 anyway. I'm wondering whether it wouldn't be enough to use the existing 

  /usr/share/hal/fdi/policy/20thirdparty/10-linuxwacom.fdi

or adjust it accordingly (how?) instead of adding more entries to

  /usr/share/sax/api/data/cdb/{Pads,Pens,Pointers,Tablets,Touchscreens}

Also it's unknown how these entries need to look like. This information wasn't really helpful to me:

'Then, configure your xorg.conf file with a "stylus" and a "touch" InputDevice sections ...'

I suggest to discuss your wacom X driver patch and how to adjust the .fdi file
with the wacom driver developer "Ping Cheng" <pingc@wacom.com>.

And/or Petter Hutterer. See 

  http://lists.x.org/archives/xorg-devel/2009-September/002290.html

I mean bringing this upstream the whole community can benefit from this.

To Stefan (posts #5 & #6) :
Please take care that the git-tree from the xf86-linuxwacom fork of linuxwacom still does NOT include the little n-trig patch required for all HP and Dell TabletPCs, such as tx2-12nn touchsmart, neither the original linuxwacom-dev and linuxwacom-prod drivers. Therefore, it still NOT benefit to the whole community !

Take a look to http://en.opensuse.org/SDB:Howto_install_OpenSuSE_on_HP_tx2-xxxx_laptops to retrieve the poor four lines of code to add to wcmUSB.c in both linuxwacom's and its fork before.

I've added a copy of my working xorg.conf to the How-To. It's certainly not the minimalist's one.

About the fdi files, some peoples reported in Ubuntu's forums that changes have to be done in xorg.conf and not in .fdi files to works. It may be a consequence of the way used by (some versions or all ?) linuxwacom to read its configuration ?

This is why I've asked you to contact Ping Cheng and/or Peter Hutterer to address this issue upstream.

I believe Ping and Petter can help you here. We definitely would like to get rid of xorg.conf if possible - also for Tablet PCs.

I have written to the author of the patch, to ask him if somebody else than him should post the patch on linuxwacom development website (sourceforge), but he hasnt't still answered to that question. I saw in linuxwacom forums on sourceforge that this little patch was discussed between him and Ping Cheng (see http://sourceforge.net/mailarchive/forum.php?thread_name=4A03EE63.3010403%40seas.upenn.edu&forum_name=linuxwacom-discuss ).

My position is : whatever do the linuxwacom project, distributions should have to patch this package for widely diffused TabletPC like HP and Dell models with this n-trig touchscreen device before waiting the upstream to be fixed, as it appears that it could have been fixed monthes ago !
This modification is small, and advantages are considerable for 99% of users : their TabletPC could operate OpenSuSE, or not.

Therefore, I've added the inclusion of a patched linuxwacom package as a desired feature of OpenSUSE : https://features.opensuse.org/308203

About fdi files, I confess that I can't figure out how to configure everything, including ATI or NVidia cards and n-trig fingers-and-stylus touchscreens, AND to keep a functionnal integration of sax2 in YaST configuration modules ? (what will display sax2 about tablet or touchscreen if configured by fdi ?)

This bug is certainly a bit more difficult than others to fix as it depends on three steps, but the three steps have to be fixed, as the reported bug is "support of HP tx2 touchsmart tabletPCs".

I suggest to send Ping a reminder. Could be that he simply forgot about the patch.

As mentioned before, Ping and Peter should be able to help you here. We really no longer want to rely on SaX2 for wacom driver configuration.

I wrote to them and submitted the Rafi's patch : http://sourceforge.net/tracker/?func=detail&aid=2887583&group_id=69596&atid=525126

Thanks. I hope you've sent them a private mail. I'm not sure if any developer is looking at the bug tracking system of SourceForge. Probably not.

Patch for sax2. To be applied in /usr/share/sax.

Instead of "/dev/input/by-path/pci-0000:00:14.5-usb-0:2:1.0-event-mouse" the device path below /dev/input/by-id would be preferred.

Example:
/dev/input/by-id/usb-Tablet_ISD-V4-event-stylus
/dev/input/by-id/usb-Tablet_ISD-V4-event-touch

Added patch to obs://X11:Utilities/sax2 and SR'ed for openSUSE:Factory. Still I'm interested in a more reliable device path ...

wacom driver patch now applied to X11:XOrg/x11-inputwacom and SR'ed for openSUSE:Factory. Closing as fixed.

So, can I test it? which package version?

Added with sax2, and updated xorg.conf, but still now working (actually don't know

Ok. So replace all occurrences of /dev/input/by-path/pci-0000:00:14.5-usb-0:2:1.0-event-mouse in xorg.conf with one of these

  /dev/input/by-id/usb-1b96_0001-event-mouse
  /dev/input/by-id/usb-1b96_0001-mouse

Try both (but not at the same time!). Does this help?

ok,
/dev/input/by-id/usb-1b96_0001-event-mouse
is working (for pen), while  
/dev/input/by-id/usb-1b96_0001-mouse
is Not working (touch interface is not working)

in any case touch (without pen) is not working

Not sure if I understand correctly what you're trying to tell me. Is it correct that it doesn't matter if you use /dev/input/by-id/usb-1b96_0001-event-mouse
or /dev/input/by-id/usb-1b96_0001-mouse as device path for pen and touchscreen?
For both cases pen does work, but touchscreen does not?

In that case please attach Xorg.0.log for /dev/input/by-id/usb-1b96_0001-event-mouse, which I would prefer.

Great, Stephan : I've tested sax2 patch from #14 : it works. But the linuxwacom package in #19 have NO chance to work, as it is based on linuxwacom 0.8.3, which is too outdated. N-trig drivers begans to works perfectly only since linuxwacom 0.8.5, which need to be patched. Current linuxwacom is 0.8.5-1, available at http://sourceforge.net/projects/linuxwacom/files/ and need patches for n-trig support, which can be found here : http://sourceforge.net/tracker/?func=detail&aid=2891575&group_id=69596&atid=525126

Linuxwacom 0.8.5 with previous patches works too, but previous linuxwacom versions DO NOT WORK properly.

I've experienced some problems with the device path given by-id, and therefore largely prefer sax2 to use by-path.

-----
To A.S. Brar : have you patched your 2.6.31 kernel with the latest hid-ntrig.c from git ? If not, this explains why touch doesn't work. You can check that with wacdump : when hid-ntrig.c and/or kernel is outdated, wacdump doesn't report touch events coordinates.

> I've experienced some problems with the device path given by-id, and therefore
> largely prefer sax2 to use by-path.

Daniel, as you've seen in this bugreport, the device paths given by-path might work for you, but obviously don't for others. Thus I believe we should stay with the ones given by-id.

Fixed in X11:XOrg/x11-input-wacom and SR'ed for openSUSE:Factory.

Thus closing as fixed again.

Why major? This is/was still an enhancement request!

Cool : Jiri Kosina say that n-trig driver will be included in 11.2 releases (see his comment in http://bugzilla.novell.com/show_bug.cgi?id=548463 ) and therefore in Factory. 

Stefan (#36) : problems of A.S. Brar do not look like a problem related to "by-path" device, and as I've reported, "by-id" do not work everytime. Peoples may encounter the same issues with by-id, which have never happened with by-path. Wait and see ?

#37 : the 10-linuxwacom.fdi do not fit for tx2-12nnxx, but a specific tx2-12nnxx .fdi file may work, even if nobody reported to have succeed without xorg.conf configuration. When some "wacom" devices exists in xorg.conf, hal settings are ignored, by default.

#40 : for anybody who try to install OpenSuSE on these tabletPC, it's more than critical ! It's a blocking issue, since touch and stylus do not and will not work with OpenSuSE 11.1. Why blocking ? Or at least critical ? Because touchscreen is THE major feature of TabletPC, both for accessibility than for technical or artistic designs.

Stefan : will the sax2 and the linuxwacom packages refered in #19 be included in 11.2 release ?

Up to now we know that working with by-path obviously didn't work. A.S.Brar needs 

pci-0000:00:14.5-usb-0:2:1.1-event-mouse
                           ^
whereas you need

                           ^

I don't have any Wacom/n-trig based touchscreen available for testing. So I
can't help testing here.

Apparently you still need to learn about the meanings of severity we use in bugzilla for openSUSE. See http://en.opensuse.org/Usability-Errors for detailed explanation.

> Stefan : will the sax2 and the linuxwacom packages refered in #19 be included

No, we're after RC2. :-( But it's available in X11:XOrg and X11:Utilities.

Thanks Stefan, Daniel for your hard work to give solution, finally I am to use at least stylus on touch screen now, where factory/11.2rc installed on it.

I am not expert, so don't know how to patch kernel, but Jiri Kosina's comment seems helpful for me.

waiting for release to fresh install my system and test again.

Thanks again.

I've read the page about usability. What I say is that a non-working tablet on a TabletPC is an issue at the same level that non-working keyboard/mouse on classical computers. A blocking human interface issue should be considered as far more critical on a tabletPC than on a server on which that is not an usability issue.

Gartner's group predict about 25-30% of market-share for touch computers in the next 2-3 years. This is why it's so important for my favourite Linux distro !

I also don't know what to do now to help to get touchscreens works "out-of-the-box" with 11.2. If the 2 packages done by Stefan (thanks !) are not included in the 11.2 release, what should we do ? Open a new bug report for 11.2 ? Enhance SDB to help newbies to find and install required packages from OBS repos ? Something else ?

I would agree, if TabletPcs would be, i.e could be the main focus of openSUSE. How many TabletPcs work out-of-the-box with openSUSE. One? Two? Maybe three? Why is it that critcial to support exactly one more of thousands TabletPCs available? It doesn't help most of the TabletPC users.

We only fix critical and security bugs for a released product. :-(

I suggest to update your excellent help article on opensuse.org and describe how to update x11-input-wacom and sax2 packages.

Just for your information.

I've updated to linuxwacom driver 0.8.5-8. Unfortunately I needed to disable the n-trig driver patch due to radical changes in the driver. I kind of do not feel responsible to discuss this patch with Ping. I do not own the hardware either. So I can't test any changes anyway.

Please feel free to provide an updated patch, so we have n-trig support soon again for openSuSE:Factory.
