[Bug 799202] Re: wacom stylus jumps with latest xserver-xorg-core
The reason Krita fails is that it uses the high resolution location and not cursor location. High resolution location evaluation is broken whenever the X server does not send both X and Y coordinates. Thus the valuator code is still wrong somehow. I have pushed a hack fix to the PPA that just drops all incoming events that don't have both an X and a Y coordinate specified. Please test it out once it finishes building.

The new packages do not fix this for me. I still get ghost jumps. This makes sense, because if the valuators are parsed incorrectly, then the Qt tablet app should draw additional loops as well.

[Bug 799202] Re: wacom stylus jumps with latest xserver-xorg-core
The Krita code that deals with tablet events seems to be this in
kis_canvas_controller.cpp:
-
void KisCanvasController::Private::emitPointerPositionChangedSignals(QEvent
*event)
{
if (!coordinatesConverter) return;
QPoint pointerPos;
QMouseEvent *mouseEvent = dynamic_castQMouseEvent*(event);
if (mouseEvent) {
pointerPos = mouseEvent-pos();
} else {
QTabletEvent *tabletEvent = dynamic_castQTabletEvent*(event);
if (tabletEvent) {
pointerPos = tabletEvent-pos();
}
}
The obvious failure point being that if the argument is neither a mouse
nor a tablet event, then pointerPos is uninitialized. I did not have
time to check yet whether the bug is caused by this or something else
entirely.

[Bug 799202] Re: wacom stylus jumps with latest xserver-xorg-core
I had a look at the Krita sources, as pointed out by Jussi, and the
problem does not come from the kis_canvas_controller code, but seems to
come from kis_canvas_widget_base.cpp.
There, we have the following code:
void KisCanvasWidgetBase::processTabletEvent(QTabletEvent *e)
{
widget()-setFocus(Qt::OtherFocusReason);
m_d-blockMouseEvent.start(100);
const QPointF pos = e-hiResGlobalPos() - widget()-mapToGlobal(QPoint(0,
0));
m_d-toolProxy-tabletEvent(e,
m_d-coordinatesConverter-widgetToDocument(pos));
// HACK
e-ignore();
m_d-ignorenextMouseEventExceptRightMiddleClick = true;
// HACK
}
My debugging shows that the problem is in the Qt hiResGlobalPos method
from QTabletEvent.
event-pos() seems to give correct results for the QTabletEvent, but
event-hiResGlobalPos() sometimes gives strange results that cause the random
lines.
For exemple, I have the following values from hiResGlobalPos (the x
coordinate):
(...)
453.731
453.682
453.779
12.4536--- weird value
453.633
453.487
(...)
So my guess is that Qt has problem getting the correct values for this
hiResGlobalPos, if anybody with a better inside knowledge of Qt can have
a look...

This issue is somehow related to issue #762938 (no pressure sensitivity with wacom tablet). A fix for pressure sensitivity was proposed by Chase Douglas in the utouch-team/unstable ppa. Using the official ubuntu Qt version, stylus position works fine, but pressure sensitivity does not work. When using Chase Douglas's ppa, pressure works fine, but the cursor position jumps while drawing. Note that the issue only happens when using the wacom stylus that is pressure sensitive, not when using the wacom mouse that has no pressure.

[Bug 799202] Re: wacom stylus jumps with latest xserver-xorg-core
My guess is that although we now are getting the right data into the right properties, Qt probably is not keeping track of the unchanged valuator values. So, if an event comes in with a valuator range of [1,1] (which implies that only the Y valuator changed), then Qt needs to copy the old X, pressure, and tilt values into the newly created Qt event. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/799202 Title: wacom stylus jumps with latest xserver-xorg-core To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/799202/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 799202] Re: wacom stylus jumps with latest xserver-xorg-core
Attached is a quick patch that inspects that valuator accesses do not go out of bounds. I changed only the motion and button accesses and not the Wacom one. The reason being that it seems to loop over all data so it should be valid. I have not tested the patch in any way, so it might not even compile. I have not tried replacing system Qt ever so I reckon someone with more experience ought to try it first. As far as the sporadical thing goes, the situation for me is the reverse: I don't get any errors for pressure but I do get it for tilt. Since my tablet does not seem to support tilt, its values should always be zero. There's also the case that I get different behavior on evemu-traces than the real tablet. Xorg log does say I am using Wacom input module. ** Patch added: valuator-range.diff https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/799202/+attachment/2425854/+files/valuator-range.diff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/799202 Title: wacom stylus jumps with latest xserver-xorg-core To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/799202/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I can confirm that on my Wacom Bamboo Pen Touch the behaviour is exactly the same as j-b-m. The only addition being that I get the huge rectangles only when I stop moving the pen (but keep it touching the surface). My tablet probably does not provide tilt information so could you try the following. First run xinput list which shows you all input devices. Check which number it has given to your stylus. Then do xinput list idnum. This shows you which valuators provide the tilt information. These are probably 3 and 4. Then run xinput test idnum and move your stylus. What values do you get for tilt axes? No matter what I do, I can't get any other value than 0 for these. Which would indicate that the huge rectangle values are generated somewhere outside X. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/799202 Title: wacom stylus jumps with latest xserver-xorg-core To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/799202/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 799202] Re: wacom stylus jumps with latest xserver-xorg-core
I looked into Qt and there are three locations where x and y tilt values
are obtained. They are all in qapplication_x11.cpp in the function
QETWidget::translateXinputEvent.
The first one is this (I have removed quite a lot of lines, check the
original to be sure):
s = XQueryDeviceState(X11-display, static_castXDevice *(tablet-device));
for (j = 0; j s-num_classes; j++) {
[stuff]
if (!proximity) {
xTilt = short(vs-valuators[WAC_XTILT_I]);
yTilt = short(vs-valuators[WAC_YTILT_I]);
pressure = vs-valuators[WAC_PRESSURE_I];
So it loops over something(?) and grabs things. Then a bit later it does
this:
if (motion) {
xTilt = (short) motion-axis_data[3];
yTilt = (short) motion-axis_data[4];
where motion is an XDeviceMotionEvent.
Immediately afte that it does
} else if (button) {
xTilt = (short) button-axis_data[3];
yTilt = (short) button-axis_data[4];
where button is an XDeviceButtonEvent.
Based on this the potential bugs are that either Qt does masked
valuators wrong or the X server gives incorrect data in event
structures. The xinput output mentioned above would seem to indicate
that the fault lies with Qt.
Chase, what do you think?

[Bug 799202] Re: wacom stylus jumps with latest xserver-xorg-core
Some background information on XInput: XInput 1.x added valuators which are axes that provide data beyond just X and Y. Unfortunately, in the infinite wisdom of the XInput 1.x creators, the valuators were not labeled. Thus, the Qt code has #defines like WAC_XTILT_I. Essentially, in XI 1.x the order of valuators is part of the ABI. However, I think only the Wacom X module has provided a stable valuator ordering, so it's all just a big mess. This means that the code only works if you are using the X Wacom input module. I'm assuming you all are, but it would be good to double check (check /var/log/Xorg.0.log). Another quirk in XI 1.x is that it provides valuator ranges instead of a bitmask of changed valuators. So, if the values in axes 3 and 5 changed, XI 1.x must send data for the current values of axes 3, 4, and 5. In XI 2.x, the server sends only the new values of 3 and 5. It is possible that there is an issue in how masked valuators in the internals of the X server are being handled, but I have not seen any indication this is the case. xinput test and xinput test-xi2 are great for testing this. You can run the same recording through both and see if there are any discrepencies. Note that natty and Oneiric are the first X servers that actually use masked valuators internally in the server. Clients who aren't fully compliant to the XI specs will only start to see issues now :). I just got to this paragraph to summarize things, and then I realized what may be the issue. Notice how the xTilt and yTilt variables are set based on a constant index into the event valuators. This works fine if the event valuator range always begins at 0. However, if only the 3rd and 4th valuators changed, the valuator range from the server would be 3 to 4, and the indexes of valid data would be 0 and 1 (shifted down by 2). See /usr/include/X11/extensions/XInput.h, XDevice*Event.first_axis and XDevice*Event.axes_count for the valuator range of an event. This would also explain why the issue is seen sporadically with pressure data but not with tilt. When pressure changes, X and Y is likely to also change. This causes the valuator range to start at 0, so the axis indices used in Qt are ok. However, when tilt changes, maybe it usually is the only valuator that changes value. Thus, the valuator range starts at whatever the tilt valuator is, and the indices used by Qt are wrong. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/799202 Title: wacom stylus jumps with latest xserver-xorg-core To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/799202/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 799202] Re: wacom stylus jumps with latest xserver-xorg-core
Hmm, looks like we are progressing in what the problem is. As suggested by Jussi, I tried the tablet sample app from qt4-demos, and I can confirm that pressure works fine. However in that demo app, when I try to use the tilt value from the tablet to set line width (in the Tablet menu Line width Tilt), I get some strange results: a rather constant fine line with sometimes a random huge rect appearing. Trying to set the color saturation from the Tilt value doesn't work either. The behavior is the same on my Touchscreen and on my Intuos 3 usb. I tested with the unpatched xserver (without the 503 patch), and with this version, setting line width from the tilt value works fine on my intuos 3, and the line width stays fine on my touchscreen that maybe doesn't provide a tilt value, but I never get those random huge rects. So it looks like the problem introduced (or revealed) by patch 503 may be with the tilt value, not the pressure... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/799202 Title: wacom stylus jumps with latest xserver-xorg-core To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/799202/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 799202] Re: wacom stylus jumps with latest xserver-xorg-core
This is getting weirder and weirder. I updated my packages and tried again. Now the behaviour is different. Just adding the struct elements does *not* break pressure. Previously it did. I verified on previous test results I had written down with an actual pen and paper. What happens now is slightly different. Patch 503 has three different parts: two code changes and the struct change. If I take out the first code part, I get pressure. Taking out only the second code part does give pressure. However I cannot for the life of me understand why this happens. The code in question does not handle pressure in any way, only coordinates. Somehow the first code block triggers loss of pressure. If I play the same recording without a Krita window, I get a drag selection box. So transforming the pen to movement+mouse click works. I suspect that this bug may be platform specific.

The TouchPointInfo* structure isn't used in xf86-input-evdev, so that

Jussi, please rebuild xserver-xorg-input-evdev against a server with

I attached 3 files, with 2 recordings in case it can help.

I don't know if it is of any interest, but I tried to replay the 2 record files that I just attached to this bug report with evmu-play. When using the official xserver-xorg-core, nothing is drawn in Krita. I can see the cursor move but nothing is drawn with both recordings (the buggy and the correct one). But when playing them with my patched xserver (without the 503 patch), both files play fine and I can see the drawings without random lines with the 2 recordings.

[Bug 799202] Re: wacom stylus jumps with latest xserver-xorg-core
I believe I found the cause of this regression. The wacom tablet sometimes sends button presses on one of the X devices that does not emit (or has not emitted yet) traditional X and Y coordinates. This confuses the server due to masked valuators and coordinate transformation. The fix is to not generate and propagate any coordinate changes if the incoming event does not have any coordinate changes. Please test out the xserver-xorg-core package in ppa:utouch- team/unstable after it has built. The package version should be 1.10.2-1ubuntu1.2~utouch1.
