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

[Favux]

I'm just guessing too. But I find the "stylus eraser" suspicious in light of append...
If you find a manual or wiki on .fdi other than the Wacom.fdi wiki let me know.

When you say wacomcpl works does that mean you can say, remap your stylus button? Do the rotation scripts work? In other words to the wacom input devices rotate with the screen?

Wow. Cool!
I will definately try this when I get home tonight.

It works!!
What's more I have no idea how since as far as I knew only root can update hal stuff.
But it works anyway. Hibernate and suspend multiple times. Everything. Wacomcpl.
The only change I had to make is to the fdi file.
Here is how I got it to work:

<?xml version="1.0" encoding="UTF-8"?> <!-- -*- SGML -*- -->

<deviceinfo version="0.2">
<device>
<match key="input.originating_device" contains="if0">
<match key="info.product" contains="Wacom">

<merge key="input.x11_options.Type" type="string">stylus</merge>
<merge key="info.product" type="string">stylus</merge>
<append key="info.callouts.add" type="strlist">hal-setup-wacom</append>
<append key="wacom.types" type="strlist">eraser</append>
<merge key="input.x11_options.BottomY" type="string">16466</merge>

</match>
</match>
</device>
<device>

<device>
<match key="input.x11_options.Type" contains="eraser">
<merge key="info.product" type="string">eraser</merge>
</match>
</device>
</deviceinfo>

(no idea why the indentations aren't showing up.)

Nice! I never knew it's possible to encode calibration info into fdi.

What's more I have no idea how since as far as I knew only root can update hal stuff.

Well, you do need root priviledge to change the fdi, which is all HAL cares about.

If you are talking about my program, it only listens on dbus for screensavor signal, which doesn't require root.

I suppose if you don't change any settings in wacomcpl, you don't even need my little program.

When you say wacomcpl works does that mean you can say, remap your stylus button? Do the rotation scripts work? In other words to the wacom input devices rotate with the screen?

Yeap to all . For my tx2000 at least. I heard rotation is a bit trickier for tx2500's ATI.

Remapping stylus button would require my little C program. Otherwise it will get reverted to default sometimes after suspend (no big deal, though, you just need to run the wacom script again, or let my program do it for you).

Hi gali98 and cyberfish,

Quotes instead of code re indents? So we learn more about .fdi and HAL, good.

And rotation is working for you Kory? We need to test this on a TX2500.

Putting the stylus button in the .fdi is no big deal.

Re: .fdi you both should check out mzuther's, just posted on post #169 here: http://ubuntuforums.org/showthread.php?t=967147&page=17

[gali98]

Yes! You can actually change any option you could do in the xorg.conf in the fdi file.


Well, the thing is, your little program (man I wish I knew C :\) calls the script right? And the script makes changes to hal. And the program is run with normal user privleges if it is put in start up applications...
I don't have any idea why it works.
I'll experiment, and see if I can't find out anything. Anyways, thanks so much! This is great!

The script is just a bunch of xsetwacom calls. I don't think it makes any change to HAL.

Oh hmm... I think I wasn't clear. The script I am referring to is the one generated by wacomcpl, not the script we used to put in /etc/init.d (that one requires root).

I don't think it's for tablet PCs, but it COULD work with some modifications...

Is there anything wrong with the fdi we have already?

[Favux]

No it's for a usb external graphics tablet. I was just showing that it has changes similar to the ones we made from the included 10-wacom.fdi. The more working .fdi's I see the better handle on .fdi's I get in lieu of a real manual.

[cyberfish]

The real manual is certainly available.
http://people.freedesktop.org/~david.../hal-spec.html

chapters 2 and 5 in particular.

I'm just too lazy to read it .
