For some reason I had trouble running the apport command in 13.04, but I also noticed that 12.10 has the same bug as well, so I decided to run it from that. Hopefully that still helps to an extent.

It would be helpful if you could collect some USB Tracedata. There are some web pages that describe how this can be done:

https://wiki.ubuntu.com/Kernel/Debugging/USB#Getting_USB_Tracedata
http://www.kernel.org/doc/Documentation/usb/usbmon.txt

If you can, reproduce the bug while collecting this data.

Thanks in advance!

Thank you for the timely reply. ^^
Unfortunately I was experimenting some more with this bug last night, and it appears to just happen at random times. I couldn't find a distinct pattern of actions that triggered it. Ill collect the data for you tonight when i have access to the victimized laptop.

Alright, I got the trace data. Honestly I have no idea how this helps, or if I even did it correctly, but here it is. Luckily though, the glitch actually occured shortly after I started the tracing, so maybe that will make it easier to pick it out from here... I also tried the cat command, but it said that a certain directory was missing, so I just did a trace on 0u.

If it helps at all, I also ran the LSUSB command, and it came up with this output:

Here's the actual trace data that I captured when the glitch occured. Lemme know if this helps. Thanks. ^^

It might be worthwhile reporting this upstream since it happens in the v3.8-rc3 kernel.

Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

[0] https://wiki.ubuntu.com/Bugs/Upstream/kernel

Will do. ^^
Thanks again for your help.

Didn't get a response after 3 days, so I filed a bug report at bugzilla.kernel.org on the issue.

Update: After experimenting more with the bug, I realized that the bug is actually within the Unity interface, not the Linux touchscreen drivers. So I've changed the bug info to reflect this.

Hello.
I have the same problem on Acer W700 tablet.
Ubuntu 13.04 (gnome-shell and unity)
kernel 3.9-rc3
touchscreen:
 ID 04f3:000c Elan Microelectronics Corp

So, it is not only unity problem...
Maybe, evdev driver or somewhere else in xorg

Also, I have found with xev utility that when clicks normal - it generates both ButtonPress and ButtonRelease events... But when clicks not works - it generates only ButtonRelease event.

It seems here is the patch for this issue (but I have not tested it yet)
https://bugs.freedesktop.org/show_bug.cgi?id=56578#c17

Thank you very much. I'll give this a shot.

I think I have the same bug with my WeTab. After logging in everything works but after a short time I can´t left-click anything in the starterbar on the left, the top bar, the unity dashboard and any non-gtk-application. For example: Chrome and Firefox don´t work but Epiphany does.
Does someone know if and how that patch works? I have no idea how to use it.

I tried the patch for the xserver but it didn´t change anything.

I also have this bug or one that is very similar. Unity stops responding to touchscreen single clicks after a period of time. I am still able to use multitouch features like swiping with four fingers to show the dock. I examined the input device in xinput and it showed clicks and releases while the bug is in effect. I will be having this problem daily, so please let me know if I can help. When it happens I either log out and back in or use the stylus.

I still need to test this theory more, but the bug seems to begin when I use the 3-finger window actions gestures. Pehaps it is a problem with the multutouch?

Nick, there's a lot of us with this problem on 2 touch devices, and it shows up for us on single touch events. See this bug:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/946417

By the way, it's not just unity and ubuntu, I've also tried Fedora and Slackware on my cando touch device and both have the same problem. It's upstream.

I've already tried reporting the bug upstream.

The issue is, they apparently have such strict guidelines for those kind of bugs that I'm baffled as to how it even works. I did my absolute best to follow the guidelines for filing an upstream bug report. After 2 hours of putting the email together and sending it with all the information I could find on it, I never received a response.

This bug is perhaps duplicate of bug 1015183 or bug 1068994. I have attached a patch (for xorg-server) to that bugs which solves the problem on the Lenovo Thinkpad Twist.

I have the same issue on a sony vaio duo 11 with ubuntu 13.04 and kernel http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-rc8-raring/ . (Kernels earlier than 3.9 do not properly support duo's N-Trig DuoSense Touch Screen - see https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/1121379 ).

 I have also tested with gnome-shell and kde from 13.04 repositories and seem to have similar issues. After some time (especially when doing fast subsequent taps on the screen or trying to drag a scrollbar or type on the on-screen keyboard) the main components of the desktop environment (panels, dialogs etc) do not accept a click with tapping, while the cursor continues to move properly at the tapped point and evtest properly reports BTN_TOUCH events.

I've recently installed 13.04 on my lenovo s10-3t which has the cando touch screen and it's still a bug.

Till, I'm using a netbook with atom processor, so patching and compiling solfware is an unbelievably arduous task. But, I can install packages and test things. Can you or someone provide a package for the patched xorg that you'd like me to test?

Till, I tried applying the patch and making the debs. There were no errot messages, so I installed the patched debs and rebooted. But I don't see any improvement. It still eventually stops responding.

There's a second part to this bug for those of us who have a touchpad mouse and that's the fact that when I touch the touchpad, the mouse cursor jumps off the page instead of moving from the point that it was left by the last touch of the screen. This problem also remains after trying that patch.

pauls, I can fully confirm your description. In fact, the mouse cursor is moved only by clicking, and it is located in the lower right corner after that. This behavior just makes you crazy, when you try to click something...

I found that when this happens, Firefox also stops to respond to clicks - real mouse click, not only touch-pad clicks. And that this doesn't happen to other software like Nautilous, and that this happens only in firefox, not on its titlebar (which traditionally is part of a window-manager - things changed so much nowadays I don't even knnow how to address it now). I am guessing this behaviour ascribes to this bug -- it happened twice on my tablet, and if it keep happening I would be able to say for sure.

This effects more than Unity but up to Ubuntu based distributions. Bug is even present on Bodhi Linux.

Previously I said, that when the computer no longer respond to touchpad clicks, it also stops to respond to physical mouse clicks. This I managed to reproduce again, thus I can confirm this behaviour. And I confirm this happens not only to firefox but also to amule, which uses wxwidget. i guess this misbehavior applies to anything that is not gtk (e.g. tcl/tk).

The fix is nearly done at https://bugs.freedesktop.org/show_bug.cgi?id=56578 Suggest you monitor that for final resolution.

good to read, that there will be a fix. I have the same issue with my Dell XPS12 (a bug report therefor also exists).

has someone tested the fix?
when will it be included in the ubuntu updates?

Dell XPS 12 , same Problem .... ubuntu 13.04.

Anything a can do , let me know ......

Lenovo Z400 Touch, same problem with 12.04...Any testing I can do, I'll do!

Got this today on Acer Iconia W700P, will help also.

I have been trying to compile this for a day now, and I know I'm doing something stupid...Can somebody point me in the direction of a tutorial or something???

Same problem here. ELAN Touchscreen on acer aspire v5 - 471pg

Same problem on my Dell XPS 12.

I really think it is some x11 or gtk patch ubuntu uses. I tried debian testing, fedora 19, *none* of them have this problem.

I also tried some "latest greatest" x11 ppa repositories with xubuntu 13.0.4: edgars and oibaf in the hopes that one of these bleeding edge x11 would fix the problem, but still there.

If someone can setup a ppa to try out various binaries with potential fixes I'll happily help test.

I've been having a similar problem on my brand-new Lenovo Z400 touch. I'm pretty new to Linux, so I'm not entirely sure what I can do to help, if anything. Let me know how if I can! I want to get the touch screen to be just fine! :)

ANYWAYS, I noticed a few times that the touchscreen suddenly works again sometime past midnight. Can't pinpoint a certain time, because I will just notice it's working again randomly, but it's always past midnight... Maybe it's just me, but it could possibly be that whatever is ultimately causing this may reset at a certain time daily... I'm not even sure if that's possible, but thought I'd throw it out there.

I believe a patch for this should be included in the next X-Server update. I'm not really sure when that is...

@ thaytoo: Can confirm the touchscreen suddenly works again. Mine also has a funny side effect; if I make any further clicks after the touch screen stops working, they will be executed some time later when it works again :D.
But this happens very infrequently - waiting so long is no option.

Would be great to see a patch in the next X-Server update - are there any details?

@the-mr-lj-88: I've been trying to keep a log of when I notice this, and have been trying to check it over every so often, but no luck with pinpointing a 'random time that it works' again. :/
I DO notice though, that at least one time a day, I get an error message asking if I want to send the error report. I always do. The majority of these have occured between 12am(midnight)-1am for me. very occasionally, they are at other times (once around 6pm). But pretty much every time I'm on the computer past midnight, an error message will pop up. 12:01, 12:25, & 12:31 are some of the recorded times. I'm thinking this error is part of this, but idk. :P
If it'd help, I can try to post a link of my touchscreen log. I'm trying to use it to potentially spot a pattern of some sort.
My mouse will follow my finger most of the time, but will not click on anything I tap. (unless I'm in the login screen after a suspend-it seems to work completely fine then, every time!) At least you can sort of click eventually possibly. xP

Since I'm still figuring Linux out, (lol) is there a link or anything that will be given with the x-server update is released?

Same problem on "Lenovo Yoga 13" on ubuntu 13.04 and 13.10 (alpha) so far.

I'm also on the Acer W700 here (with Ubuntu 13.10). I'm getting all kinds of similar symptoms. Gnome and Unity have problems with touching the menu immediately upon logging in. I have to open the launcher view in both of these environments in order to interact with the menu via touch. Then, after a while, I cannot touch to click anything!

After a little bit of interaction with XFCE, touch clicking also stops working.

For whatever reason, the most reliable environment seems to be E17. I can use multiple applications for an extended period without losing touch-click functionality.

I have the Acer Iconia W500. Getting the exact same problem. The touchscreen and clicking would be fine at 1 moment and the next the clicking kinda gets disabled and i cant click using the touchscreen.

Someone please email me at: <email address hidden> if someone found a fix

@Matthew Goodman (matthewthegoodman) this is not a wish list, it's a bug tracker.

@Micah F (fitchmicah) the issue with GNOME is probably that bug: https://bugzilla.gnome.org/show_bug.cgi?id=697192 -- GNOME 3, the "touch optimized" UI doesn't work with touch screens.

I'm on Arch Linux + KDE (because of the said GNOME bug) now, everything works as expected. So it's only a matter of time and Ubuntu not being a bad player in the open source game (as they sometimes are) until this is resolved.

why did this bug consider a duplicate of #1068994. ? i thought that is an issue with the ubuntu tablet . by the way, fix it quick, please. this really bother me :(

referring to bug 1068994, it seems to be fixed in 13.10.
