That's intentional, for network performance reasons.   I didn't want to try
to create a realtime network application given the potential for shaky
wireless.  The painting algorithm is written in terms of strokes anyway so
it would be very inefficient to try to paint two strokes simultaneously on
one XO.

If you have a friend available, I'd love to hear how it holds up over a
Jabber server with both people scribbling simultaneously :)

The erase should be propagated.  Good idea regarding the option to keep,
I'll see if it can be done (the receiving XO would have to queue canvas
updates until the Alert was cleared - Sugar doesn't really provide for modal
alerts).

Yeah, that's definitely how it's intended to be!   It was designed such that
both users can paint anywhere at the same time using different brushes, but
that the strokes appear in a consistent order on both XOs.

Good idea!  As of v11 the painting canvas can be arbitrarily sized (it used
to be locked at 1/2x the window size), so it might be smart to add a "change
canvas size" option now.

* The mouse drawing problem was also visible in collaboration.


Yep, this is a global bug- I'm waiting to release the next version publicly
until it and a few other things are fixed.

Thanks again for the reports Chris, it's amazingly useful (and motivating)!
:)

Wade

I just tried the pre-release v12 of Colors! in collaboration
mode with 2 XOs, both running Wacom graphics tablets via an
ejabber server (xo1share.org).  It was pretty cool watching
strokes from one Colors! Activity appear on the other:

* The display update seems to be by continuous stroke:
   XO #1 user draws a curve not lifting pen.  After the stylus
   is lifted from the tablet the stroke updates on XO #2.

* The mouse would need to be moved on the other XO for the
   screen updates to propagate.

* The colors and brush parameters are common to both XOs
   although the display of the settings widget (color and
   brush type) did not update with changes from the other
   side.

* Since the cursor is shared between the two activities,
   it would be better if drawing on one Activity moved the
   corresponding cursor on the other XO.

* Erasing the screen was only an option on XO #1 (the inviter)
   *but* the clear screen did not propagate to the other XOs
   so further drawing on XO #1 was not in sync with the images
   on XO #2.  Suggest that clear image be propagated with the
   option to do a local save to Journal on XO #2 so that work
   is not lost if they wish to keep it.

* It would be really cool if each XO had its own pointer with
   brush/palette/... options.  One mode that would be nice
   might be a sort of side-by-side version where each XO would
   be able to draw its own part of the screen (by mask, not
   necessarily by rectangle) so the students could work on a

* The mouse drawing problem was also visible in collaboration.

Gary Martin reported this too.  It's an issue that appeared when I stopped
Colors! from pegging the CPU all the time.  There is an idle event that
needs to be turned on when playback is running, it should be a simple fix.

Yep, makes sense - the mouse events wake up the 'update' loop which allows
the playback to make progress.  There should be an idle event doing this
while playback is active.

How can one get an image of the drawing for

Git builds have a Copy button which copies the canvas to the clipboard.
Note that Copy & Paste semantics will be slightly different from normal
apps, in that Copy will copy the current canvas state, while Paste will
paste into the Reference Image.

Good point - It would be nice to be able to specify Suppress as a ratio that
takes into account the screen resolution.  Perhaps a filter in the mouse
event handler would be more effective after all, since it could just take
into account the screen space movement when discarding events.

Good idea!  Zoom in will remain the same (e.g. focus on the mouse cursor),
but I will change Zoom out to pop the stack.

 Maybe one of the Wacom buttons could be assigned to the Frame key event?

Perhaps we can map it to Mouse4 or some other obscure mouse button, and then
patch Sugar to recognize that as the frame key.  That would actually be kind
of nice for people with many-button mice to be able to open the Frame
without reaching for the keyboard, since the Frame is mouse driven anyway.

You're welcome, Wade.

I tried to get an image of my finished drawing
from the Journal but the only option was to
resume Colors!.  Then when it resumed it seemed
to hang.  I then clicked on Play and dragged
the slider to 100 and the image finally appeared.

Trying to reproduce the problem, I noticed that
if I move the stylus pointer while the program
was resuming, it looked like progress started to
be made or at least updates to the display.

When I tried Play in with my current drawing
made via wacom tablet, the animation never
did complete.  I don't know if the problem
was me not waiting long enough or what

How can one get an image of the drawing for
sharing/printing/...?

I don't know if all wacom tablets have the same linear
resolution.  Ideally, the value for "Suppress" would be
calculated from the native tablet resolution and the
drawing area pixel dimensions.  e.g. a tablet with only
1000lpi resolution might work better with a value of 25.

Maybe whiten the image slightly as if looking through

You might keep track of the zoom center for each
level and then just pop the stack.  The problem
I had would not have occurred if the zoom in and
zoom out operations were inverses.

The 'Center image' toolbar button is great, too.

I think the buttons look like mouse-ish events.  At any
rate they can be detected and acted upon.

The "hand" keys actually do work in Colors! Yay – this is the first  
activity I know of that uses them, a big round of applause for Wade!!  
So, you can pan the canvas about like you can in Photoshop when  
holding the spacebar and dragging.

P.S. thanks for the Option "Suppress" "60", makes the Wacom draw in

This is good reasoning, and I wasn't aware of the Supress option - I'm
pretty new to Linux programming and X in particular.  I had been considering
implementing that kind of filter in the PyGTK mouse handler.  I've updated
the xorg-dcon.conf on dev.laptop.org to include this setting.

Yep, 60 works well enough though that it's probably not worth a
configuration option.  I will still work on optimizing the painting
performance though.

That's a good idea.  When I reimplement Photo Snap, I'll do it that way (so
you are painting over it, e.g. the white background will show the image when
it's enabled).

This should be documented better, or maybe have some visual feedback.  Zoom
in & out keep the mouse cursor on the same point in the canvas before and
after the zoom operation.  This is handy for quick zooms, you just point at
the area you want to detail and zoom in.  In Git I have added a 'Center
image' toolbar button though, since it can be hard to recenter. the image.
You can also always scroll the image manually by holding the Hand button and
dragging with the mouse.

Maybe one of the Wacom buttons could be assigned to the Frame key event?
Can this be done in xorg-dcon.conf?

Hi Wade, this script worked well for me, and the tablet stays working  
after a reboot. I also made the xorg.conf changes as suggested by  
Chris (Option "Suppress" "60") and it's a very good improvement for XO  
hardware Before this extra step the canvas would only redraw once you  
stopped drawing, even with a small brush.

It is true that reducing the update rate would lower the
pen position resolution of lines...but the Bamboo tablet
has a linear resolution of 2400+ lines per inch which is
about 12X the XO pixel resolution and 24X your 2X reduced
drawing canvas.  As a result, even with skipping pen
deltas of 24 or less the pen output events will still
be at the finest drawing precision.  This is not even
including the fact that the brush is more than a single
pixel wide typically.

If you add an entry under the first wacom Xinput entry in
your xorg-dcon.conf file like:

   Option "Suppress" "60"

you'll get much better drawing response with the existing
infrastructure.  I tried 10-72 and to keep up with faster
sketching or larger brushes, the rate needs to be at 50 or
greater.  After the above edit and a 3-finger-salute to
restart the X server on the XO, Colors! basically worked
well with the tablet.

There is a command line configuration program (xsetwacom)
that could be used to configure Wacom tablet settings
without editing the xorg-dcon.conf file.  I don't know
if a restart of X would then be required.  It might be
possible to base a control panel interface calling the
underlying utility per Tomeu Vizoso's previous mention
in this thread.

To improve beyond the Suppress technique will require
improved event handling optimization in colors.py.  My
guess is that the best approach will be to encapsulate
tablet specific handling at a lower level for efficiency.

I tried the earlier photo snap and it was awkward to toggle
the underlying photo image.  It would be more helpful if the
photo could be drawn over as if on tracing paper.  The toggle
on/off would still be useful at different levels of refinement
of the painting.

There appeared to be a problem with the Zoom in and
out function as zooming all the way out, and then back in
results in the canvas offset by various amounts.  I was not
able to make it shift back without restarting the Activity.

Finally, I'm not sure how to handle this but it was difficult
to trigger the Frame exposure via the tablet since the drawing
area seems to be exactly the entire screen.  If it were to be
extended a bit at the top then the Frame would be easier to
get to from the tablet only.

I've got an old serial Intuos that I'll try to get configured
this weekend.  I'll let you know how it goes...  If we get
this working, maybe Amazon could add a "People who bought this
item [the XO], also bought this [Wacom Bamboo]"...  :-)

Re: [Sugar-devel] Wacom Bamboo with XO?

Wade, 

I tried: 
sudo depmod 
sudo modprobe wacom 

but all I got was an error from the modprobe: 
FATAL:  Module wacom not found. 

I then tried: 
sudo modprobe linuxwacom 
and got the same error.

Want to report that the wacom.ko from Paul was also the final step in  
bringing my Wacom Intuos to life. Is there some magic trick to getting  
it to the insmod wacom.ko after a reboot (I have to run it again after  
each boot)? I'm sure this is standard kernel hacker fodder, but not  
something I dabble with much.

Great to see this working!! How's best to get this into the 9.1  
distro? Does this need a ticket to get formal attention?

Awesome!  I've update the wiki page with a link to a script that just does
it all for you.

Yeah, it's a shame that support was removed (via a driver rewrite which
ignores the PT) in recent kernel builds.  Otherwise, I was going to add it
at the same time.

The mouse events go at a higher priority than the expose events, so the
screen update waits until you stop moving if it gets behind.  But, at the
end your entire stroke should appear.  I would be concerned about reducing
the update rate, it might lead to less accurate drawing.

I've got some optimizations planned to the C module which should make it
better, and I think there are some bottenecks in the X server that slow
things down and could be fixed, but my recommendation for now is to draw
slower :)

I'd like to see the next OLPC Software Release contain the wacom drivers.
It would especially help activity developers prepare for XO-2.

BTW, Colors! version 11 did not appear to have
> the photo snap capability.  Was that removed?


See Nirav's response.  I'm also planning to add Paste support so you can
just snap the photo in Record (or whatever) and paste it into the Reference
image, then paint over that.

Best regards,
Wade

Re: [Sugar-devel] Wacom Bamboo with XO?

[Nirav Patel]

Chris,

We're working on switching from gstreamer to the pygame camera module.
Gstreamer in 8.2 had some changes that broke the pipeline Colors was using.
While it would have been possible to change the pipeline, switching to
pygame will be easier/better for both the videopaint and photo snap parts.

This will likely be done before the end of the month.

That was the missing step to the instructions.
I downloaded wacom.ko, did an insmod wacom.ko
as root and restarted X et. voila!

My test tablet was the small BambooFun by Wacom
with a tablet area almost exactly the same size
as the working area in Colors! on the XO.  I had
time to try out both size and opacity and it was
a pleasure to have the pressure sensitivity and
the fine control (although, the XO tablet mode
test routine showed that the existing hw was at
least capable of position resolution if not
pressure variability...).

The only catch is that the drawing output
lags the tablet strokes by quite a bit.  My
guess is that the event processing cannot
keep up with the data rate.  I seem to remember
that there was a driver configuration related
to that which might be used to throttle down
the fire hydrant.

Great job and many thanks, Wade!  If this
could be wrapped up in some sort of package
update it would be a *very* nice selling point
for the XO to the G1G1 customers/donors.

BTW, Colors! version 11 did not appear to have
the photo snap capability.  Was that removed?

Chris

 OLPC folks, it might be nice to update xorg-dcon.conf to support Wacom
 tablets, and to include the linuxwacom package in builds.  I think
 that deployments would be well served to have a few cheap graphics
 tablets available for art classes, etc.  If you're interested, the

Odd, thanks for the reports!  I already fixed the Wiki instructions.

I'm not sure what's different about my system, it's mostly stock 767.  I had
previously installed pgf's wacom.ko using insmod:

http://dev.laptop.org/~pgf/wacom.ko

to /lib/modules/`uname -r`/kernel/drivers/usb/input/

However, I assumed that the yum install linuxwacom overwrote it.  Perhaps
not though, I'm new to Linux kernel modules.  Try grabbing and installing
that kernel module, and see if it magically works.

This is great news but it did not work on my setup:
os767 with a BambooFun tablet.

I do not see any entries for the wacom in /dev/input
and a wacdump of all the possible /dev/input/event#
entries showed all unknown.

For my yum install it pulled the same version as Gary
reported.

   Had you done some previous installs that might have
   done addition configuration or driver installs?

   What version linuxwacom do you have?

   What /dev/input entries?]

   What do you see with wacdump for them?

Also, the sudo cp of the xorg-dcon.conf from the Colors!
instructions does not have the '!' in it and will not
work.  I had do su to run the command and escape the
'!' as a history expansion character with a backslash.
I was not able to get a combination of escapes that
would work with the sudo emulation...

 Well, I haven't yet figured out how to get an appropriate
 OLPC kernel build set-up but from my investigation to date
 it looks like the gtk.gdk class interface already has the
 "smarts" to talk to tablets.

 By default, Wacom USB tablets start out in a generic HID mode.
 The application would need to recognize the tablet, then
 enable the full tablet driver and configuration.

  http://linuxwacom.sourceforge.net/index.php/howto/theory

 From my reading of the gtk.gdk page it looks like those
 should map directly to the tablet access info on the Wacom
 HOWTO site.

 http://linuxwacom.sourceforge.net/index.php/appdev

 There is even a command line utility to config
 the tablet that could probably be integrated into the
 Sugar shell process or Sugarized into an activity of sorts:

Hey Wade, sounds great! Unfortunately I'm not having any luck here  
with an XO running 8.2-767 and an Intuos model Wacom tablet. Any one  
else had any success?

BTW: After yum has installed linuxwacom.i386 0:0.7.9.8-6.fc9, the  
additions to xorg-dcon.conf made, and a reboot just to make sure – If  
I go look in /dev/input/ I still see no wacom device listed.

Re: [Sugar-devel] Wacom Bamboo with XO?

[Wade Brainerd]

Okay, Colors! v11 supports Wacom tablets, with pressure sensitivity.
Instructions for setup are on the activity page, it's really pretty
simple.

OLPC folks, it might be nice to update xorg-dcon.conf to support Wacom
tablets, and to include the linuxwacom package in builds.  I think
that deployments would be well served to have a few cheap graphics
tablets available for art classes, etc.  If you're interested, the
Colors! activity bundle contains the fixed xorg-dcon.conf.

Hi, in case someone is interested, adding a control panel section to
Sugar is quite easy once you know a bit of pygtk, look here for the
already existing examples:

Re: Wacom Bamboo with XO?

[Wade Brainerd]

I imagine if we could get it working and if the driver isn't too
large, the OLPC guys would be willing to include the module in 9.1.

Has anyone gotten it compiled and tried the gtk.gdk.Device test yet?

Well, I'm going to try to get follow the Wacom
instructions for installing the tablet drivers.
I haven't built or installed a linux kernel or
drivers so we'll see how that learning curve
goes...then there are the special idiosyncracies
of the XO. :-)

Once the driver and kernel modules are built for
the 8.2 os kernel, how would we go about distributing
the drivers in a usable fashion.  Following kernel
compile and link instructions won't work.  We need
something like a signed update.  Is there any way
to have a signed update by a developer rather than
the OLPC?  Otherwise, is there a way to make the
tablet driver available for an Activity?

Re: Wacom Bamboo with XO?

[Wade Brainerd]

For someone with a tablet, it would be nice to see the results of a
simple PyGTK program which reports X, Y and Pressure from the
gtk.gdk.SOURCE_PEN device, using the gtk.gdk.Device API.

http://www.pygtk.org/docs/pygtk/class-gdkdevice.html

If this works, it would be quite easy to integrate Wacom support into
Colors! and other Sugar activities.

Re: Wacom Bamboo with XO?

[[EMAIL PROTECTED]]

Paul,

Are you using the driver code from http://linuxwacom.sourceforge.net/  ?
I had intended on trying this but have been too busy to get the time   
set up the correct environment or follow all the steps involved for  
the initial setup
http://linuxwacom.sourceforge.net/index.php/doc

If you get something you think is workable let me know and I can test  
it with one of my Wacom Intuos 2 tablets.

Note there is also a mouse as well as a pen with this tablet so the  
mouse code needs to be compiled as well.

thanks for all the good work!!

Re: Wacom Bamboo with XO?

[David Van Assche]

I have a cintiq board (wacom with tft touch screen built in) and this
works fine with the flavours of Linux I've tried it with. Granted,
I've not tried the xos, but it works fine with ubuntu. Really all the
touch configuration happens in xorg... I managed to get it working on
an eeepc with xandros too, so I dont see why it wouldnt work with an
xo. (not that I'm comparing the 2) Anyway I'd imagine using the
instructions found here and following the fedora core 3 guidelines
should get you up and running:

I'm partly set up to build kernels, I can give it a try at some point.

Ultimately though, just mouse position and clicking isn't nearly
enough.  You *at least* need pressure information for a decent tablet
painting experience.

are you already set up to build an olpc kernel?  if so:
- run "make menuconfig", select
Device Drivers
Input device support
Tablets
 and change the Wacom entry to ""

 save your changes, thne

- "make modules"

- copy drivers/input/tablet/wacom.ko to the XO, and insmod it.

I can put in some testing effort here as I have a Wacom Intuos tablet  
here. Paul, any quick hints/pointers on building the wacom.ko module  
for an XO, sounds like you've solved the big step already :-)

Re: Wacom Bamboo with XO?

[pgf]

building and insmod'ing wacom.ko lets the Sapphire tablet move
the mouse cursor.  i confess i've never used a tablet, so i don't
know whether the button on the stylus doesn't behave as a mouse
button is expected or not.  also, the motion i get when moving
the stylus on the pad is relative, not absolute.  there are no
module parameters, so any tuning must be via some other
mechanism.  i can supply the driver module to anyone who would
like to try it.

i'm probably not the right guy to pursue this further, but i've
added a mention of tablet support to #7326, which is a tracker
for requested modules.

If you guys can get a driver working and expose the API, I'll add
support to Colors!.  It already has support for pressure sensitivity
(variable brush size and/or opacity) in the painting engine.

we have a wacom tablet ("Sapphire", whatever that represents)
here at 1cc, which we can test.  the XO doesn't include the
wacom.ko module which it seems to want.  i can try building the

Wacom Bamboo with XO?

[Chris Marshall]

Has anyone had any success getting a
Wacom USB tablet working with the XO?

The new Bamboo series is affordable
($79 US), about the same size active
area as the XO display, and could be
a substitute for the deprecated/soon
to be abandoned pressure sensitive
touchpad on the original XOs.

This could be good "value added" for
the G1G1 XO-ers.  It would be a perfect
fit for the Colors Activity.
