wacom tablet -- external USB vs. built-in OEM serial

SaintDanBert · 07-24-2010, 09:51 AM

NOTE -- "Similar Threads" all speak about really old distro details.

There has been a lot of effort invested in getting external USB connected anything to work well during the connect then disconnect processing. It seems that there are troubles with OEM serial digitizers like those built-in for a tablet-PC. The built-in OEM devices do not have the same sort of connection events to trigger device creation and configuration.

Q1: Does anyone have any knowledge or experience with this that they can share?

Q2: Does anyone know how to make all of the find-hardware then create configuration processing visible?

While I find several postings that describe "... edit xorg.conf ..." but then those edits don't want to work with the recent evolution in Xorg and X11-server configuration that deprecates (abandons?) xorg.conf.

Q3: Does anyone understand what is going on with Xorg and X11-config to help me get my tablet working?

Q4: Has anyone used an external USB tablet, then adapted those configuration details to get an OEM tablet working? I know that every tablet is different, but if the external device connect-creates-config process works best, it seems there might be value here.

I use wacom bamboo with Ubuntu, I was surprised when i first connected it. Nothing happens. Latter i realized that wacom was automaticaly installed.

Since my tablet is a built-in, OEM serial tablet. I can track the digitizer output by watching cat /dev/ttyS1.

Here is some information that I hope helps.

Code:

xinput --list

⎡ Virtual core pointer     id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer     id=4	[slave  pointer  (2)]
⎜   ↳ TPPS/2 IBM TrackPoint          id=10	[slave  pointer  (2)]
⎜   ↳ Serial Wacom Tablet eraser     id=12	[slave  pointer  (2)]
⎜   ↳ Serial Wacom Tablet touch      id=13	[slave  pointer  (2)]
⎜   ↳ Serial Wacom Tablet            id=14	[slave  pointer  (2)]

    ↳ AT Translated Set 2 keyboard   id=9	[slave  keyboard (3)]
    ↳ ThinkPad Extra Buttons         id=11	[slave  keyboard (3)]

I also have the following details:

I'll send lsusb if you think it will help, but ...
what else do you need to know.

wanted to mention that i use xubuntu, so you can try to boot you system with live cd, so you can see if you can move cursor with pen.

The tablet-digitizer mostly works off-the-blocks. My stylus has three "buttons" or sorts -- the tip, a side button, an erase button. I can touch the screen and the mouse cursor jumps to that point. I can click and drag and such.

I've installed the package tablet-screen-rotation-support to get orientation changes to work: laptop==>landscape and tablet=portrait.

I need to calibrate my digitizer both as a laptop and as a tablet. This means that when I touch the screen with the stylus, the mouse pointer location is exactly under the point-of-contact. There is a package called wacom-tools that offered a "control panel" utility for calibration and other settings. That package is not available (yet?) for ubuntu lucid. I'm told there is a new utility, "xcalibrate," but I cannot find where it is available.

Q1: How do you calibrate your digitizer?
(A typical calibration utility presents cross-hairs at several points on your screen. You touch the center with the stylus. The utility knows the location where the screen showed the target and your touch presents the corresponding digitizer location. Processing against all of these differences results in a calibration. There is at least one landscape and one portrait calibration.)
