HOW TO Set Up the Bamboo Pen & Touch in Lucid

[Favux]

I'm with Robert, it's as it is smooth for me.

Admittedly the touchpad/screen part of the tablet's resolution is nowhere near the digitizer. Quicksand & torturedutopian are you running a very high resolution on your monitor? What resolution would that be?

[torturedutopian]

Favux : well, I use a standard 1920x1080 resolution. What makes me think something is wrong, is that it feels less smooth than a regular touchpad.

Anyway, I don't plan to use it as a mouse, but I was just wondering

Thanks !

Hi torturedutopian,

That's noticeably higher than my resolution on my ancient monitor. So we may be on to something.

Hi,

I've exactly the same issue with my tablet (bamboo fun pen&touch)
my laptop is a samsung nc10 with an intel GMA945 as graphic card.
I've tried with an external screen (1920*1080, 22'') and on the default screen (1024*600, 10'') and the result is the same (the phenomenon is maybe more pronounced on the highest resolution)
I'v also this fluidity problem with the stylus but far less pronounced! (you can use it without problem but if you need a high precision in your movement like 1px then there is few issues)

I'm running at 1280x1024. That's pretty low-res by today's standards.

I might be able to shed a little more light on this. I think there might be an overly aggressive "de-jitter" algorithm at work here.

I opened up Gimp and tried to draw using the touch. I thought -- since the pointer jumped around by multi-pixel increments when I moved my finger -- that I could draw some thin "pencil" lines around the screen, then zoom in and count pixels to see what the exact interval is.

But there is no exact interval at all. I could move the pointer away from the starting point and then move back, and be off by a single pixel. I can't just move a single pixel directly, though.

So I wonder if there's a threshold -- if you move LESS than the threshold distance from the starting point, the driver assumes you're trying to sit still, to keep the pointer from vibrating around. When you exceed the threshold, boom, all of a sudden you're at least 8 pixels away.

I haven't had time to peruse the code to see if this is possible. Maybe this weekend.

Yes, 1024 x 768 here on an old CRT.

Hi everyone,

It's possible this all may be moot. It turns out Dmitry, the kernel input tree maintainer, won't accept the Bamboo P&T 2FG patches because they are not MT protocol compliant. Of course the 2FG stuff was written before the multi-touch protocol came out. So Henrik has just submitted an MT based patch for the touch-only model Bamboo. If that's accepted then they'll try to extend it to the rest of the Bamboo P&T's in the wacom.ko. My guess is that will also require a rewrite of the X driver part of the Bamboo P&T code. So basically, unless translating the existing 2FG code to MT compliant protocol is "easy", we're being set back a couple of months.


Hi Quicksand,

I know Obe1kenobe had spin locks in the kernel part of the code. Ping wouldn't accept them and put in some filters. I think he ended up taking (most of) the filters out. I'm pretty sure there are still filters in the X driver part, as we see with the 30 to 300 change.


Hi Robert,

Same here.

Favux, I love you (like a friend, I meen)

You made my CTH-460 work with my ubuntu 10.04.

I tried the same thing, last year, to make it work and it never worked. I had to get back under m$ to take my notes, and under ubuntu for the homework (I'm studying in computer science)

Now, I'm searching how to create gestures with the stylus!!

Hi Sylvain,

Good! Glad you finally got it working.

Now, I'm searching how to create gestures with the stylus!!

You want Tom Jaeger's EasyStroke.

I was trying to map the keys, and missed something.

I want to map Button2 and Button3 to pgup and pgdn, respectively.

Firs, core keyword is not recognised anymore, so I do:

xsetwacom set "pad" Button2 "key pgup"

and it's says invalid key 'pgup'
I tried with capital letters, with pageup, nothing works

What's the keyword for the key pageup?
