    I have seen that error once or twice (on a studio 17), but haven't been able to make it occur reliably enough to have a chance to debug.

    On my xt, when the screen fails to send events, I've found that windows doesn't recover it either, and that I've needed to reboot or power cycle, as suggested by ntrig on their website.

    Its pretty hard to write a fix for these problems when I can't see a stream that fixes them. I wonder if the usb control supports power cycling that one device. Seems like an extreme solution but it would beat power cycling the laptop.

When I rebooted finger and pen touch on the screen worked as a left click only, so no scrolling, no right click. I read through the last 30 or so pages and the first couple, but now am more confused than ever as to how to get touch working. Some info, not sure how useful it is...

    The Win7 firmware I'm using is 2.184 as the newest version 2.239 still isn't out for 32 bit and I installed 32 bit Lucid Lynx (did a clean install rather than upgrade from Koala). Running 2.6.32-21-generic kernel, Gnome 2.30.0.

    Any help gratefully recieved. Cheers.

    Franc Kaos.
    Configuration wise, with lucid release you should only need to adjust auto configuration file for the wacom as described in http://swiss.ubuntuforums.org/showpo...&postcount=945
    (that change has been sent in to the wacom mailing list and hopefully should be integrated in the near future).

    Gimp (and possibly others) doesn't care if an input is floating, it will still draw. There are plenty of easy work arounds, but if its actually a problem we should work out a clean solution.

    Also keep in mind that there are only a few ntrig firmwares that actually send touch events while the pen is in range. If you update to the multitouch firmwares, they don't.

    rafiyr, do you know which version Lucid is using for the stock kernel? It is looking like the BTN_TOUCH or BTN_DOUBLETAP is not in the single touch portion for the kernel module. If I recall correctly, the Vista firmware and possibly the 2.59 firmware is defaulting to the single touch mode. Those two versions seem to be having a problem with the touch not producing the left click.
    Sorry, I'm not sure which version made it to the lucid release. I will check on that.

    Btw, I did find some flaws in my design of the post 952 hid-ntrig.c, nothing terrible but it does mean the rejection model isn't really all that different than the earlier versions. If you are using that, activation_(width,height) basically become an accept/reject threshold. But since I set the defaults considerably smaller (and scaled to the physical resolution), you should see improved responsiveness.

    I do have a solution, but am still working out a more complete analysis and testing, should be posted by mid week.

    ...
    I am only requesting the xorg.conf file for now until I can confirm that xorg.conf.d does not make evdev stop working when it is not configured through xorg.conf.d.
    Thanks Ayuthia for the fast response. My xorg.conf file is:

    Section "Screen"
    Identifier "Default Screen"
    DefaultDepth 24
    EndSection

    Section "Module"
    Load "glx"
    EndSection

    Section "Device"
    Identifier "Default Device"
    Driver "fglrx"
    EndSection

    Would you please install input-utils and send the output of lsinput and lsusb.

    A cleaned up replacement for the previous (2010_04_27) version:

    http://ofb.net/~rafi/2010_05_04_hid-ntrig.c

    Again I would like some feedback. I'm pretty confident in this version, though I would still consider the filtering parameters experimental. If you try it and get some ghost contacts, please let me know.

    You can adjust the parameters in /sys/bus/hid/*1B96*/ or when you load the module.
    For example to restore mimic the old filter behavior with:
    Code:
    modprobe hid_ntrig min_width=68 min_height=43

    A problem I might be having is that the ntrig firmware I began with was 2.59, but I then upgraded to 2.184 (ie I uninstalled 2.59, then installed the later one). I emailed HP tech support as to release dates of the latest 32 bit firmware, but received no answer as of yet. It's frustrating, so close (the screen responds to touch - as in left click, and in the right place), just no scroll, zoom or right click. Anyway, much thanks for the help.

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

    Installing UBUNTU 9.04 on HP TX1000 laptop (touchscreen+fingerprint)
    1. Install Ubuntu 9.04 Jaunty
    2. Connect to Internet and open SYSTEM>ADMINISTRATION>HARDWARE DRIVERS
    3. Install NVIDIA current version
    4. Install Broadcomm B43 driver
    5. Install software modem driver
    6. Download eGalaxDriver from website http://home.eeti.com.tw/web20/eGalaxTouchDriver/linuxDriver.htm
    (download for kernel 2.6.xx)
    7. Extract tarball and run setup.sh from terminal with sudo
    8. Restart Computer and run (with Alt+F2) “eGalaxTouch” (without quotes and linux is case sensitive)
    9. Configure your touchscreen
    10. Open xorg.conf with following command
    sudo gedit /etc/X11/xorg.conf
    11. Under Section “Device” add the following line
    Option “RandRRotation” “True”

    12. Create two launchers on your gnome panel with following commands:-

    xrandr –o 1 (for tablet mode) P.S. u can set it “3” as well if u want opposite rotation)
    xrandr –o 0 (for Laptop mode)

    13. Install Cellwriter from synaptic
    14. Install xournal from synaptic
    15. Install the following for finger print recognition
    lib-fprint
    libpam-fprint
    fprint-demo
    16. Open file common-auth
    sudo gedit /etc/pam.d/common-auth
    (delete all lines in the file and paste these lines)

    Auth sufficient pam_fprint.so
    Auth sufficient pam_fprint.so
    Auth required pam_unix.so nullok_secure

    (the first line can be copied 3-4 times if u want to allow more than 1 chance to register fingerprint)
    17. Create keyboard shortcuts for screen rotation (here is an example)
    Key Command
    Ctrl+Alt+UP xrandr –o 0
    Ctrl+Alt+LEFT xrandr –o 1
    Etc
    Etc
    (Notes: This Guide will work for any UBUNTU installation upto Karmic (9.10). Unfortunately in Lucid, the developers have tried to provide native support for Touchsdcreen and Nvidia but it has turned out to be sloppy. And there is no xorg file as well. So viable options are to uninstall nv and nouveau drivers and install Nvidia and the run sudo nvidia-xconfig from command line. After that follow steps 4 to 17)

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

    Ok I did a fresh install of 10.04 yesterday an it is the same story. I have the latest firmware installled from win7 64 bit, and I have ubuntu 10.04 64 bit installed. I have now read this post 3 times over and this still seems to be a bit too complicated for me and I was wondeing if there was a kind soul that could meet me in the #ubuntu channel and guide me through this maze so I can get the touch and multiple touch working. Thank you in advance to any and all willing to help me undertake this adventure. I'm also thnking shout makin a video documentary of my centre into Linux full time on my laptop and the comunities help. Might end up postig it to YouTube I the hopes of bringing more people on the border into the fold. Anywho my name on irc is tophu you can hit me up if you see me I there or send me a message on the forums with a date and time and I will hop on. ^_^ again thank you all for your hard work on getting this workig it has been awesome watching this come together over the past year or so.
