The source distribution includes wacomcpl which, among other things, can
calibrate the stylus on a table PC.  It would be nice to see this
included in wacom-tools (or a separate binary package, at your
discretion).

Is there anything this can do that can't be done with xsetwacom (which
is in the package) ?

Work is underway on a couple of fronts for a gui interface that doesn't
involve getting all covered in tcl.  It is planned for the package to
supply such a thing, but for the moment there are a number of higher
priority (and lower level) issues that need to be fixed to give that
a stable base, so it may be a little while still.

Yes, it can be used to calibrate the stylus on a tablet PC.  xsetwacom
doesn't have that feature.  (It displays "targets" on the screen to
select with the stylus, and generates appropriate calls to xsetwacom
based on the stylus offset from them.)  A very important and useful
feature :-)

It's pretty easy in this case, just depend on tk8.4 and that should be
it.

Changing the stylus/eraser/etc. pressure sensitivity is a pretty common
task. I think I speak for all math-illiterate users out there when I say
that it's much easier to adjust an ugly Tk slider than to input 4
integers parameters for a bezier curve (using xsetwacom set
PressureCurve...).

Please include/package wacomcpl. Thanks :)

It seems that the i386 package in the archive really has the
aforementioned bug. I downloaded it again from a different mirror to be
sure:

dreamscape:~$ wget -q
http://ftp.us.debian.org/debian/pool/main/w/wacom-tools/xserver-xorg-input-wacom_0.7.4.1-3_i386.deb
dreamscape:~$ dpkg -c xserver-xorg-input-wacom_0.7.4.1-3_i386.deb | grep
/lib/udev/check_driver
-rw-r--r-- root/root       499 2006-05-18 08:51 ./lib/udev/check_driver

Woops, wrong bug number. Should have gone to #384873

Are there any plans to fix this bug by say October?  I understand that
long run goals include less ugly GUI, but there's ample reason to
include a simple fix in the short term.

I've personally disliked wacomcpl for a long long time.

    1. Ugly Tcl interface
    2. It tries to be too smart and edits my ~/.xinitrc, and *ALWAYS*
       botches it.
    3. When "xsetwacom list dev" returns no devices, it borks.

Most of wacomcpl functionality can be done by RTFM + xsetwacom, so it's
not usually an issue. However, as pointed out here, stylus calibration
could use GUI to set the parameters.

So I wrote one :). I'm attaching a Gtk+perl script that helps
calibrating the stylus. If it doesn't get a list of devices from
'xsetwacom list dev', then  it looks in the environment variables
'WACOM_*'.

It also doesn't touch your ~/.xinitrc. It only saves the calibration
parameters to ~/.calibrate.X (where X=1,2,3,4 depending on the tablet
rotation). It's up to the user to source (or not to source) these files
on startup. I personally automate by running

    WACOM_STYLUS=<name of your stylus device>
    tablet_rotation=$(xsetwacom get "$WACOM_STYLUS" Rotate)
    [[ -f ~/.calibrate.$tablet_rotation ]] && \
	source ~/.calibrate.$tablet_rotation

on startup, and every time the screen is rotated.

The previous calibrate script broke with an upgrade to
xserver-xorg-input-wacom 0.10.3+20100109-1. Here's a modified version
that works. Some changes:

    1. Calibration parameters are now saved to ~/.calibrate.X where X is
       the output of "xsetwacom get stylus Rotate". In old versions this
       used to be a number between 1 & 4. In new versions it seems to be
       one of NONE, CW, CCW, HALF.

    2. Resetting calibration broke with the upgrade. This is because the
       script used "xsetwacom getdefault" to find the tablet width /
       height. Looks like getdefault is not supported with the latest
       version of xsetwacom. Instead, I use the xyDefault property to
       reset parameters, and find the tablet width/height.

reassign 315142 xf86-input-wacom
retitle 315142 Gtk+Perl alternative to wacomcpl
thanks

wacomcpl is officially dead now, and has been dropped from the upstream
wacom package.  The wacom-tools package is also dead, and has been replaced
by the xf86-input-wacom package.  Since I'm about to get the wacom-tools
package removed from the distro, I'm reassigning this to the new package
so we don't lose track of the calibration script that GI sent, before it's
also replaced by some more permanent solution.

GI, I thought I asked you about this before, but we probably need some sort
of licence statement from you to actually distribute this ...  Your intent
is pretty clear to me, but that's probably not quite enough to keep the
-legal folk all happy about it.

Cheers,
Ron

I'm certainly happy to distribute with whatever licence is most
convenient for you guys (GPL, I presume). Will this email suffice? If
not, let me know what you need me to do.

If the legal folk need my real name/etc. it's

    GauNOSPAMtam IyNOSPAMer

with NOSPAM removed. If you include my real name somewhere, I request
you do so in a manner that won't show up in search engines. I'd like
people who Google me to find my own website and research before the open
source stuff.

Thanks,

GI

Here's an updated version of the script. With the recent xsetwacom
upgrade, it wasn't harvesting device names correctly. Should be fixed
now,

GI

The upgrade to xserver-xorg-input-wacom 0.12.0-1 broke everything.
Here's an update of the calibration script to work with the new
xsetwacom syntax.

I've heard there's a way to set the calibration / etc. through HAL.
However, as long as xsetwacom "Works for me (tm)", I'll follow the path
of least resistance.
