HOW TO: Install a LinuxWacom Kernel Driver for Tablet PC's

[KSavvas]

Hi to all,
I was using 9.04 Jauntry with no problem with full functionality out of the box on my Fujitsu Siemens T4210 Tablet but after upgrading to 9.10 Karmic, my stylus begun to act strangely. To be more precise :
The tap with the stylus acts as right click.
The stylus buttons have no effect..
The eraser button acts as right click when it is tapped on the screen.
The system is up to date and with clear xorg.conf.
I have tried changing the file 10.wacom.fdl as suggested but after rebooting the stylus was completely dead.
The strange thing is that at GDM Login screen everything works fine, with on screen keyboard.

Another problem is that after following the instructions that ebullient posted in post #634 adding the khnz repository and installing fjbtndrv had no effect in the functionality of the tablet buttons. Also no rotation.

Please forgive me for my noob questions
Thanks in advance
Savvas

Hi KSavvas,

Welcome to Ubuntu Forums!

Let's take a look at a few things.

The xorg.conf is the default Karmic one?

The xinput output may tell us something. In a terminal enter (copy and paste):

xinput --list

and also:

lsmod | grep wacom

Hi Favux,
Thank you for your answer.
Glad to join Ubuntu community.
Let me start telling you that I found a way to make it work.
Well not the solution I wanted but we can try make it work correctly.
What i did:

• Deleted old ~/.xinitrc (root owned - not executable)
• run wacomcpl and changed Sylus Button 1 property to "Right", Button 2 to "Left" and Button 3 To Middle. That meaning reversing the functionality of the buttons. Also changed Eraser button 1 to "Right".
• Saved and made the file executable.
• Registered the file to System>Preferences>StartUp Applications.
• Commented the last line of /etc/X11/xinit/xinitrc

After rebooting nothing changed but having in mind ebullinet's post about having to restart X server, I logged off and on and ...
The stylus is working as expected.
So the problem now is the annoyance having to restart the X server after the initial boot.Oh by the way how can i enable Ctrl+Ald+Backspace to restart X Server?

For the use case history i am attaching the info you requested

Any Ideas?

[Favux]

Hi KSavvas,

Sorry, my bad. The lsmod/wacom (wacom.ko) is for usb tablets and I knew yours is serial. Just habit I guess.

Oh by the way how can i enable Ctrl+Ald+Backspace to restart X Server?

Just go to "System > Preferences > Keyboard > Layouts > Layout options..." > and select "Key sequence to kill the X server" and check the box in front of Control + Alt + Backspace. Then you should be good to go.

It almost sounds like there is a time out on the Wacom (or some other part of the serial chain) driver trying to attach during the standard boot and an X restart is "slow" enough for Wacom to load. You could look at Xorg.0.log (in /var/log/) or view it with System > Administration > System Log. That may tell us what's going on.

Your "xinput --list" looks good. How did you get it to say stylus and eraser? A .fdi or xorg.conf or?

[KSavvas]

Hi Favux,

Thanks for the tip on killing the X Server.
The names on the "Xinput --list" come from a script placed in /etc/init.d that I created after reading your post #93 on this thread. Thanks again.
The Xorg.conf file is the one created by Karmic Installer.

There is also one line with no marking preceding that i can't figure out what it means

xf86WcmSerialValidate: bad magic at 3 v=a0 l=9

If you want i can attach the complete file

Also, using a script you provided in an other thread I have simple rotation working with no problems. I've attached the script to a panel launcher and I have on demand rotation.

[Favux]

Hi KSavvas,

Good so you have rotation to tablet mode now. My understanding of where we're at now is that everything is working? Other than having to restart X to get the digitizer.

The Wacom part of the Xorg.0.log looks good. But you are right:

xf86WcmSerialValidate: bad magic at 3 v=a0 l=9

is worrisome. That suggests some problem with validating a serial device which may be your Wacom digitizer. So I guess you should attach your Xorg.0.log. It's interesting to note the new 0.8.5-5 linuxwacom (out yesterday) says:

Updated serial ISDv4 support with newer protocol.

You have to wonder if that's about the problems serial tablets are having in Karmic. But since rotation is still broken with it I wouldn't try to compile it.

I suppose the "input device fsc tablet switch" could be your fjbtndrv. Fujitsu FUJ02B1 is your keyboard. I'm not sure what the button stuff is, do you have a touchpad?

We could also take a look at your lshal.

lshal>KSavvas_lshal1.txt

[KSavvas]

Hi Favux,

I could say that we are ok. (thanks to you). Having to restart the X Server is just a nuisance.
I'm attaching the files you requested. Have a look at them and if you make out something let me know.

Is there a possibility that "input device fsc tablet switch" means the tablet's lid switch ?
I'll try to uninstall fjbtndrv package and see what will show up. It doesn't work anyway.

Thank you for your help
Savvas

P.S -I think that it will be very useful if you take a look at the xorg.0.log that is created at first boot.
Here, will see some intresting things such as

May be the source of the problem?

gali98,

As a total newbie, I have to say your instructions were perfectly clear. I have an HP tx2525nr and you saved the day on this one.

When I installed Ubuntu 9.10 fresh (on a shrunken partition - dual boot Vista), The stylus worked, but I could not use the touch with my fingers.

Now the touch works well - at least 50% better than it did in Vista. I can do most anything without opening the top. Using onboard (just type 'onbaord' from the terminal) I can type on the screen to enter passwords or fill forms.

All in all - Great job

Louis

Hi LouisBlank,

Welcome to Ubuntu Forums!

Yes, gali98 always does good work!


Hi KSavvas,

Sure that could be the tablet lid switch or swivel hinge switch.

The lshal looks fine. Your right that first boot Xorg.0.log is interesting. The linuxwacom driver drops the stylus with:

usbDetect: can not ioctl version
Wacom ISDV4 control data (0) error in * query
(EE) Couldn't init device "PnP Device (FUJ02e5)"
(II) UnloadModule: "wacom"
(EE) config/hal: NewInputDeviceRequest failed (1)

Which by the way I've seen before on serial tablets. But what I find interesting on the first boot is:

(II) config/hal: Adding input device PnP Device (FUJ02e5)
(II) LoadModule: "wacom"

Compare that to what you see after the X restart Xorg.0.log:

(II) config/hal: Adding input device stylus
(II) LoadModule: "wacom"

And you'll see all the rest of the plug and play lines are missing too. I haven't seen that before. Maybe the problem isn't the serial communication but is instead some bug in PnP interfering with serial communication?

hi, me again.. i've updated the system to karmic, and it's nice to see how almost everything works out of the box. but i just couldn't conform with not having the touch :S
so i tried gali's instructions again, and i got uncalibrated touchscreen (i even tried modifying some values in the fdi file) with no wacomcpl device showing (i had gotten this kind of uncalibrated touch before.. it's like the screen is a really little box on the upper left corner)

i attached my lshal output, and the fdi file i used is the modified one with the calibration values at gali's tutorial (i did tried the default one first, but with the same results). i have the tx2500us
btw, i'll be gone till tomorrow. just so you (the kind soul who'll help me) won't wait for a quick reply

edit: i tried running two times the command before step 1 in the tutorial. what compile error should i have? i didn't compiled anything :S
