Hi,

Very nice, Loïc. I've been looking for a simple description like this since I 
got my Wacom... I guess this is as simple as it gets at the moment.. Since 
I'm using Debian/Mepis-pools I'm missing one of the packages, but I trust 
that the needed 'InputDevice' lines are defined in the 'ServerLayout' for the 
Stylus etc.

The only thing that bothers me is the sentence 'Remember to plug your tablet 
before you boot, it makes things simpler'.

The fact that X has problem detecting my Wacom when I plug it in has bothered 
me ever since I got my own Wacom. Personally I think that you should only 
need to plug it in and then should work (I can accept a little configuration 
the first time, but after that there should be no hazzle). No restarting X, 
no switching VTs after unplug/plug etc.

Sure, it was easy to get it working (SimplyMepis 3.4-3, kernel 2.6.16.4 (with 
swsuspend2 patches), wacom.ko from kernel source, and wacom_drv.so from 
0.7.3-1). Once I got everything in place I could use it! Kind of.. Unless I 
plugged it in before X started it was just a glorified mouse, no pressure 
sensitive stuff in Gimp and stuff (and until two hours ago whenever I pulled 
it out I got a kernel-oops, wonder why that stopped, no sw-updates made.. 
Yes, I have saved the oops ;).

Oh, one more thing. I only have a laptop so I have my tablet connected about 
50% of the time it's running. When I shut it down I only suspend it, and so 
far doing that with the Wacom plugged in (truly configured, not in 
the 'glorified mouse' mode) forced me to reboot it every time unless I 
switched it to a text-console before suspending, anoying..

So I got a crazy idea last friday. Why not do for tablets as they've done for 
mice? Create an aggregation device which is always there, and always possible 
to open which forwards the events from every Wacom tablet (usually people 
only have one connected, right?).

Took me two days and now I have a module that allows me to plug/unplug it 
whenever *I* choose to. Also, as long as I have that module loaded before X 
starts, all I have to do is to plug the Wacom in and start using it. 
Wounderful!

Now, personally I don't really like this solution (but it works fairly 
well) 'cause imho this should be handled automatically by the X-server or a 
helper application (where the different tools should be managed as well). As 
far as I know they're planning for something in Xorg 7.something, but I 
haven't seen anything yet, as the page has not been updated for a while 
(http://wiki.x.org/wiki/XInputHotplug). Maybe they've posted information 
somewhere else though..

I'm really interested in how viable you think the idea is, I haven't seen 
anything like it on the net so far. I bet there's lots and lots of pit-falls 
that must be handled which I havn't touched as I hardly knows the 
Wacom-specific stuff as well as you guys.

If someone wants to have a look at the module-source, mail me and I'll send 
you the tar-ball. Since I'm a kernel-newbie I'd love to know what I actually 
do right with the module ;)
