[Ubuntu-x-swat] [Bug 1015183] Re: Inconsistent mouse events for Acer T231H multitouch monitor

I have partial (full) success (on the Lenovo Thinkpad Twist, an Intel-
based convertible, see also bug 1068994):

I have rebuilt the current Raring package of xorg-server
(1.13.3-0ubuntu5) with the following two patches:

1. http://cgit.freedesktop.org/~whot/xserver/commit/?h=touch-grab-race-
condition-56578-v2id=0498a4f0e0b90a850df7022a3356f10adabff855

(found via https://bugs.freedesktop.org/show_bug.cgi?id=56578#c17)

2. http://lists.x.org/archives/xorg-devel/2013-April/035878.html

and after that clicking via touch screen on the Lenovo Thinkpad Twist
works reliably. Only remaining problems are (but the touch click ability
does not get lost by them):

a. In Chromium when you create a new tab, the new tab contains icons for
web apps (at least the app store and perhaps some examples). These icons
cannot be clicked by touch, only with a mouse. All the rest in Chromium
is clickable by touch.

b. Touch clicks do not work in XBMC, but after using and leaving XBMC
with an external mouse on the normal desktop touch-clicking works again.

These are probably separate bugs which got revealed by the now working
touch click.

Complete patch for xorg-server is attached.

I have built xorg-server with my patch also on the Nexus7 now and it
works perfectly there with the desktop and all applications, too, and on
the Nexu7 XBMC and Chromium's web apps work with touch.

It also seems to fix the Nexus 7 (bug 1068994).

Can't reproduce with plain metacity, because the menus open so quickly
with it, whereas with Unity on this hw the effects slow it down so that
the race is hit.

Tried several of the recent patches on top of 1.13, but they haven't

I just repeatedly tap on the top-most icon (the one which has the Ubuntu

any effect. I.e., the launcher no longer gets ButtonPress and
ButtonRelease events out of them.

I've added a wealth of logging (see xorg.log attachment) to try to understand 
what's happening on the server. From looking at it could see the following:
From touches 2 to 26, launcher is the first window in the list of listeners. 
From touch 27 onwards, the root window is the first one. Problem is, from 
touch 27 onwards, xserver fails to pass the touch ownership down to the 
launcher window because there's always an older pointer-emulated touch (touch 
26) lying around which it apparently can't get rid of (i.e. properly process).

Yes, they are at least closely related (most likely have the same cause)
as a pointer-emulated touch gets stuck because of failed resource
lookups in RetrieveTouchDeliveryData() as well.

With the 4 patches mentioned in bug 56557 applied (comments 3 and 4),
the bug (missing ButtonPress and ButtonRelease events) manifests itself
already on the second tap on the touchscreen.

Again, due to a failure in RetrieveTouchDeliveryData()

[Ubuntu-x-swat] [Bug 1015183] Re: Inconsistent mouse events for Acer T231H multitouch monitor

2012-10-05 Thread Trent Piepho

Found out something new.  I compiled the git version of evdev,  xf86
-input-evdev-2.7.0-20-g5af11b6, and when multitouch isn't enabled, the
core state problem is gone.  The autoconf script doesn't detect XI22 on
Precise because the X.org version is too old, so MT isn't enabled by
default.

Once I modified configure.ac to turn MULTITOUCH back on, then the
problem was back as well and state is locked to 0x100 after the
touchscreen is used.

I've also found that I get far more of the problems Cédric mentions when
ginn is running.  It seems like what happens is the touchscreen stops
generating ButtonPress events, but it still does motion events and state
is still locked at 0x100.  So the effect is that one is moving the
pointer around with the button held down, but never pushing the button.
This usually seems like left-click has stopped working.  But I imagine
the state problem and the resulting drags with no click can explain in
some strange behavior seen in certain apps.

2012-10-03 Thread Trent Piepho

I see this same behavior on a Samsung Slate 7, which has an Atmel
maxtouch multitouch touchscreen.  Running Precise, with xserver-xorg-
input-evdev 1:2.7.0-0ubuntu1.2 and xserver-xorg-core
2:1.11.4-0ubuntu10.8.

If I don't touch the touchscreen since the X server has started, xev
reports the state of events as expected when using a mouse.  0x000 for
the ButtonPress, 0x100 for motion with the button down and the
ButtonRelease, then 0x000 after.   However, after the touchscreen is
touched once, the state becomes 0x100 for the first ButtonPress from the
touchscreen and stays at 0x100 thereafter, even after the ButtonRelease.
Keyboard keys, mouse clicks, mouse motion, etc. are all state 0x100
until the X server is restarted.

2012-07-05 Thread Cédric Dufour

Hello Martin,
Yes indeed, it seems we're bumping is several different issues. Yours - and its 
fix - helped improve the global picture. I have absolutely no understanding of 
how all that X and multi-touch works, so I don't know where to start from (in 
respect with where/how to report the other issues). All I can do is give as 
detailed a report as possible, so those who know can extract what hopefully 
useful information they can (and maybe point some directions for further bug 
reporting and/or testing).
Thanks for keeping up with me so far ;-)
Cheers

 Is the patch you referenced intended as a replacement for both my
 patches? Working with the touch screen alone, things work out fairly
 well. But if I also use a mouse, then the lack of a TOUCH_END event
 still causes the mouse moves to register as drags, i.e. with state
 0x100. So I feel like your patch might be a suitable replacement for the
 one in comment #12, but the one in comment #11 is still required.

If you aren't receiving a TouchEnd event, then there is something wrong. 
The patch you are reverting is needed to fix a different bug. If you can 
reproduce the issue easily, please describe how. Then we can look to 
resolve it.

Thanks!

 With that patch by Chase, I also wonder what would happen if two touch
 devices were used simultaneously.

 When I both touch my screen and click my conventional mouse button, I
 get two button events, but the state is the bitwise or of both, so the
 second click will be pressed button 1 while button 1 was pressed.
 Makes sense, in a certain way, although it might well confuse some
 applications.

 But what if I had two touch devices controlling the core pointer? I
 believe it is likely with the current setup that in this case, the
 second device would generate a ButtonPress with state 0x000. Or is it
 impossible for more than one touch device to control the core pointer at
 a given time? I don't have more than one device, so I can't test this.

 I'll agree that given current technology, this seems a rather rare
 corner case, and probably not worth the effort to deal with properly.
 But any shortcomings in that respect should perhaps at least be
 documented somewhere.

Great point here :). I had to look at the code to determine the correct 
answer. I worried that, like you said, it would be buggy if you had two 
touchscreens. However, this should not be a problem.

Input devices have a two-layer hierarchy. There are slave devices and 
master devices. Slave devices represent a physical device, like a 
touchscreen. Master devices represent a group of slave devices. Most 
people only have one master device configured, and all the slave devices 
are attached to it. If you have two mice, you can create a second master 
and attach one slave mouse to each. Then you'll have two independent 
pointers on screen :).

A client can listen to events from master and/or slave devices. The 
events look and behave almost exactly the same. When you press your 
mouse button, a button press event is generated for the slave device and 
the attached master device.

If you have two touchscreens with one master, then each slave device can 
emulate a button press event. However, there can be only one emulated 
touch per device (no matter whether it's a slave or a master), so the 
first touch is emulated for the master, and the second touch is not.

Thanks!

I am receiving the TouchEnd, but it doesn't update the core state the
way it should.

 The patch you are reverting is needed to fix a different bug. If you can 
 reproduce the issue easily, please describe how. Then we can look to 
 resolve it.

Please re-read comment #8.

Steps to reproduce:
 1. Start xev
 2. Touch screen and release
 3. Move regular mouse

Expected behaviour:
 2. Release event with state 0x100
 3. Mouse move with state 0x000

Actual behaviour:
 3. Mouse move with state 0x100

Behaviour if you simply disable the check for the TOUCH_END flag in
UpdateDeviceState:
 2. Release event already with state 0x000

Hello Chase,
Thank you for looking into this.
When not subscribed to the X.org mailing list, obtaining the patch is kind of a 
hassle (I couldn't find a download option and I'd rather avoid copy/paste). Can 
you post it here too, so we can download/test it? Or will it be included in the 
next xserver-xorg-core package update?
Thanks again,
Cédric

[Ubuntu-x-swat] [Bug 1015183] Re: Inconsistent mouse events for Acer T231H multitouch monitor

Hi Chase,

thank you for looking into this, and working towards a solution.

Is the patch you referenced intended as a replacement for both my
patches? Working with the touch screen alone, things work out fairly
well. But if I also use a mouse, then the lack of a TOUCH_END event
still causes the mouse moves to register as drags, i.e. with state
0x100. So I feel like your patch might be a suitable replacement for the
one in comment #12, but the one in comment #11 is still required.

I guess you head a good reason to write the changes I mentioned in
comment #8, the ones which #11 backs out. I must confess I still haven't
fully understood the rationale behind that commit, mostly because I
still don't know about that listener concept. So perhaps you want to
improve that change instead of reverting it. A proper proof should
probably get rid of every occurrence of the TOUCH_END macro in the code.
It should be tested on a setup with both a touch and a classical mouse
device.

[Ubuntu-x-swat] [Bug 1015183] Re: Inconsistent mouse events for Acer T231H multitouch monitor

With that patch by Chase, I also wonder what would happen if two touch
devices were used simultaneously.

When I both touch my screen and click my conventional mouse button, I
get two button events, but the state is the bitwise or of both, so the
second click will be pressed button 1 while button 1 was pressed.
Makes sense, in a certain way, although it might well confuse some
applications.

But what if I had two touch devices controlling the core pointer? I
believe it is likely with the current setup that in this case, the
second device would generate a ButtonPress with state 0x000. Or is it
impossible for more than one touch device to control the core pointer at
a given time? I don't have more than one device, so I can't test this.

I'll agree that given current technology, this seems a rather rare
corner case, and probably not worth the effort to deal with properly.
But any shortcomings in that respect should perhaps at least be
documented somewhere.

[Ubuntu-x-swat] [Bug 1015183] Re: Inconsistent mouse events for Acer T231H multitouch monitor

2012-07-04 Thread Cédric Dufour

Hello,

Thanks Martin for your PPA and the precise packages; unfortunately, I
run amd64 :-/

I first applied only #19 patch (yes, it did require some adjustments) to
the latest precise X.org packages (1.11.4-0ubuntu10.3): behavior remains
the same (at least as far as Compiz plugins are concerned: Expo
triggers the issue systematically, Shift Switcher one time out of
two).

Then I saw Martin's comment and applied patches #11 and #19: behavior
remains the same (as far as Compiz plugins...) AND windows moving
(clicking-holding-dragging) is lost right from the start.

I think we can conclude that #11 triggers the windows moving (clicking-
holding-dragging) is lost issue (since I also bumped into it #17)

Now, I'm wondering whether Compiz might have some problem on its own.
Example given: I loose single/double click as soon as I launch the
Expo plugin and select (double-click on) a viewport. After, no amount
of single/double-clicking does anything (on desktop icons, windows
minimize/maximize/close buttons, panel applets, etc.). BUT, single
/double-clicking still work in Compiz plugin (if I launch the Expo or
Shift Switcher, single/double-clicking works).

I also gave #19 patch (alone) a try without launching Compiz (use metacity 
alone instead) or multi-touch (ginn) stuff. Before, even in that 
(no-compiz/no-ginn) scenario, single/double-clicking got lost rather rapidly. 
Here, I've been clicking and double-clicking around and using applications for 
several minutes without any problem. As soon as I launch ginn again, I start to 
have some problems with the applets icons (most of the time, they don't react 
to single click, though they sometime - rarely - still do). Other 
single/double-clicking still works.
Launching Compiz alone (without ginn), and all problems are back.

Conclusion using patch #19, without patch #11 (cf. windows moving
(clicking-holding-dragging) is lost issue), without Compiz (cf. single
/double-clicking is lost issue) and without ginn (cf. applets react
only whimsically to single-click issue), single/double-clicking at
least seems to work reliably enough to allow the touchscreen to be used
(before, it was a no go), even if sometime, one must (single) click
two time on an icon for the expected behavior to happen.

About that sometime, one must (single) click two time on an icon for
the expected behavior to happen: I can reproduce the behavior
systematically by: 1. clicking on a network-manager icon (menu opens),
2. clicking on the desktop to close the menu (menu closes), 3. clicking
on a network-manager icon again (menu does not open; instead, a
selection rectangle is drawn), 4. clicking on a network-manager icon
again (this time, menu opens again)

Let me know if I can help any further.

[Ubuntu-x-swat] [Bug 1015183] Re: Inconsistent mouse events for Acer T231H multitouch monitor

Hi Cédric,

Although this took a little while longer, the amd packages have been
built successfully by now, and are available from my ppa.

I have the impression that your problems manifest in cases when some
application is listening to the higher level touch interfaces,
presumably using XInput. My problems on the other hand occur in a bare
bones X where applications only use the core pointer. Those appear to be
two sides of a coin: the commit reverted by comment #11 was intended to
deal with a changing set of listeners, which to me sounds like some
gesture-interpreting software. So it seems you need that fix, but I
can't have it, as it breaks the core pointer. Let's hope someone finds a
fix which will work with multiple listeners and still maintain proper
core pointer state. As things work all right for me at the moment, I
have little incentive to work on a part of this issue that doesn't
affect me. Particularly as I haven't got all this gesture stuff set up
to work for me, so I cannot test things yet.

I applied the patches in #11 and #12 to the current precise xserver-xorg-core 
source (1.11.4-0ubuntu10.2) and unfortunately, it does not solve the atmel 
maXtouch loss of single click (I can reproduce that behavior systematically 
by calling Compiz's Expo plugin and double-clicking one of the viewport; after 
that single-click is lost).
Worse, drag'n drop does not work anylonger (e.g. to move a window by 
cliking-holding-moving its title bar).
Sorry for the negative report.

2012-07-02 Thread Chase Douglas

Hi Martin,

Thanks for finding this issue. Good work on making some patches, but I
don't think they are quite right. We need to set the internal button
state of the device when the touch begin comes in, otherwise we will not
get the right result when we call {X,XI}QueryPointer().

A simpler solution would be to modify DeliverTouchEmulatedEvent(). There
is the following line:

ptrev-device_event.corestate = event_get_corestate(dev, kbd);

We need to modify it so that it also passes in a boolean to
event_get_corestate() to determine whether to mix the touch emulated
button state in with the normal button state. Then, we tell the function
to mix in the touch emulated state only on touch update and end events.
We can reason that this is correct because only one touch may be
emulated at a time per device, and because only one window may receive
an emulated button press for the touch begin at a time.

I will attempt to make a test and a patch for this tomorrow.

Thanks!

I have a patch for the second issue of the mouse state during replay.
Will attach it here shortly. I'm currently trying to get this to my PPA,
for quantal first and for precise afterwards.

Editing the change log, I found that the removal of the TOUCH_END is not
part of the orig tarball, but comes from an ubuntu patch,
507_touchscreen_fixes.patch. The changelog entry by Chase Douglas quotes
bug #974887 as a reference on those modifications.
