Description Sam Tuke 2014-12-13 14:17:06 UTC
Description of problem:

After upgrading from Fedora 20 64-bit to Fedora 21 via Fedup, my Dell XPS 15 9530's touch screen no longer works. Touching the screen has no effect on Gnome 3.

When touching the screen and running sudo cat /dev/input/event16, the terminal fills with output, presumably indicating that input data from the screen is being received.

The device entry in /proc/bus/input/devices:

I: Bus=0003 Vendor=06cb Product=0ac3 Version=0111
N: Name="SYNAPTICS Synaptics Large Touch Screen"
P: Phys=usb-0000:00:14.0-6/input0
S: Sysfs=/devices/pci0000:00/0000:00:14.0/usb3/3-6/3-6:1.0/0003:06CB:0AC3.0004/input/input17
U: Uniq=
H: Handlers=mouse2 event16 
B: PROP=2
B: EV=b
B: KEY=400 0 0 0 0 0
B: ABS=260800000000003

Version-Release number of selected component (if applicable):

I'm running kernel 3.17.4-301.fc21.x86_64.

How reproducible:

Upgrade only applied once.

Steps to Reproduce:
1. Install Fedora 20 x86_64
2. try out the touchscreen (works)
3. Upgrade to Fedora 21 Workstation via fedup
4. test the touchscreen (fails)

Actual results:
Touchscreen unresponsive

Expected results:
Touchscreen works as an input device as before

Comment 1 Benjamin Tissoires 2014-12-15 15:21:37 UTC
Thanks for the report.

Can you provide the following 2 things:
- the dmesg of the failed kernel (under F21)
- the evemu-record (package evemu) of your touchscreen under f21. (You need to run evemu-record as root or use sudo).

Comment 3 Sam Tuke 2014-12-15 16:04:03 UTC
dmesg output should now be attached (machine has been running for a while). sudo evemu-record gives:

Comment 4 Benjamin Tissoires 2014-12-15 16:21:16 UTC
Thanks for the logs.

Unfortunately, the dmesg output starts too late to have the proper initialization device recorded in them. You can get the full output with "journalctl -b -k" or by rebooting and re-asking for a dmesg.

Also, I am interested in the full evemu-record when you are touching the device. This allows us to check if the problem lies in the kernel (missing few key events) or in the Xorg driver (by replaying the device). Please re-attach the full evemu-record to the bug (as a plain text file).

How can I pipe this to a file effectively? evemu-record is interactive and requires that I select the necessary event number. Thanks for any tips.

Thanks.

BTW, I do not see anything which would explain the misbehaviour.

Just calling "sudo evemu-record > output.ev" is fine. The device list is printed out to the stderr, so it will be printed out on your terminal, and not in the file :)

Also, you can directly specify the input node when you know it:
sudo evemu-record /dev/input/event16

Great thanks - now attached.

Comment 10 Benjamin Tissoires 2014-12-15 18:31:42 UTC
From what I can read (and test) from the evemu output, the kernel does its job properly. Touches are reported correctly, and they are all released at the end of the record.

Moving the bug to xorg (though on my local F21, the replay of the touches definitively does something on the screen). Peter may have an idea of what is happening.

Comment 11 Sam Tuke 2014-12-16 01:28:37 UTC
Thanks Benjamin

Comment 12 Peter Hutterer 2014-12-16 04:51:29 UTC
same here, seems to work just fine with

xorg-x11-drv-evdev-2.9.0-3.fc21.x86_64
xorg-x11-server-Xorg-1.16.2.901-1.fc21.x86_64

do you have a custom xorg.conf? Can you attach the Xorg log output please?
journalctl _COMM=Xorg.bin _PID=xyz

where xzy is the PID of the last/current run (shown in square brackets if you leave the _PID bit off)

Comment 15 Peter Hutterer 2014-12-17 08:44:54 UTC
ok, I admit - no idea what's happening there. the evemu replay works just fine here and the log looks just fine too. I honestly don't know what's happening here.

what desktop environment are you running?

Darn. Thanks for looking.

> what desktop environment are you running?

Gnome 3.14.2.

Comment 17 Illtud Daniel 2014-12-17 13:18:59 UTC
I have the same issue. evemu tracks input events fine, xorg log [attached] seems to be OK, similar to Sam's. Is it usual to have the ignore line (which both Sam & I do):

Rha 12 01:54:20 localhost.localdomain gdm-Xorg-:0[1164]: (II) config/udev: Adding input device eGalax Inc. eGalaxTouch EXC7910-1031-12.00.03 (/dev/input/mouse2)

All was working fine until FC21. Same xorg & evdev driver as you, Peter, Gnome 3.14.2 as Sam.

This is getting weird.
Could you try to run the following commands in the running session:
$> sudo rmmod hid-multitouch ; sudo modprobe hid-multitouch

Then check if the device now works and what is the new Xorg.log.

> Is it usual to have the ignore line (which
> both Sam & I do):

Yes, it is. The kernel creates 2 nodes for the touchscreen: the generic evdev handler (/dev/input/eventX) which is used by Xorg, and a legacy mouse node (/dev/input/mouseX). Xorg can safely ignore the latter.

> All was working fine until FC21. Same xorg & evdev driver as you, Peter,

Could you also try to run from a liveUSB of a plain F21, and see if the touchscreen works?

Yes that works! Now the touchscreen is operational again.

Xorg log for removing & reloading hid-multitouch

Yes, removing and reloading hid-multitouch works. Thanks for your help on this, Benjamin.

Here's the additional xorg logging for that.

Comment 24 Peter Hutterer 2014-12-17 21:52:24 UTC
Sam: two things to try. Take your evemu recording that you attached here, then

    sudo evemu-device recording-file.txt &
this will print the path for the new device
    sudo evemu-play /device/path < recording-file.txt

does that move the pointer?

kill evemu-device, then run
   sudo evemu-play /dev/input/eventXYZ < recording-file.txt

this time with the path of the real device (16 according to comments above)

does that do anything?

Comment 25 Peter Hutterer 2014-12-17 21:54:57 UTC
oh, and another thing: does this happen with a plain X session started through xinit?

Comment 26 Peter Hutterer 2014-12-17 22:02:16 UTC
ok, final question I think: what's the output of xinput list-prop "device name", with the device name as displayed by xinput list.

Comment 27 Bill Nottingham 2014-12-18 03:35:00 UTC
Not the original reporter, but:

After some investigation... the trigger that makes it nonresponsive for me is a suspend/resume cycle. Somehow, I'm not surprised.

Following your instructions from comments #24/#25:

1. Playing back the recording from evemu-record to the fake evemu-device does activate the cursor.

2. Playing back the recording from evemu-record to the *real* device also activates the cursor... and makes the touchscreen responsive again.

In fact, even something as simple as "cat <touchscreen device> ; <ctrl-c>" seems to reset it properly.

something disabled your touchscreen, question is what though. Benjamin found that issue too and noticed with xinput watch-props that it gets reset as soon as he changes it. So something in the desktop environment must be toggling it.

I have no idea why playing back the recording through the real device would activate it though, if the device is disabled the server should drop all events.

Reassigning to g-s-d, looks like it's the fix to the gnome bug here that causes this: https://bugzilla.gnome.org/show_bug.cgi?id=720295
or at least, that's very likely candidate. Downgrading g-s-d to 3.14.1 should fix this issue for now.

Output of this is:

What should I replace /device/path with?

Sorry I'm a bit lost.

Sam.

Comment 34 Peter Hutterer 2015-01-07 23:49:19 UTC
evemu-device should print the newly created device path. otherwise just run evemu-describe without arguments, that'll list all available devices and you can check which one is the newly created one. it'll be something like /dev/input/event7 or so (don't confuse it with the physical device you recorded from)

Comment 35 Vitaly Bordug 2015-01-08 09:36:37 UTC
On latest F21, stock gnome desktop, similar HW - and only way to get touch back after resume is to restart X.

Device is present in xinput list, recordable via evemu just fine. Playing the recording back does not result in anything (at least, touch is still  stuck). It is somehow semi-alive - when tapped, the pointer disappears from where the mouse is, but soon reappears again when mouse moved; tapped events are completely ignored by X app I was trying to tap.

More information: the device gets somehow kicked into floating slave after first tap, rendering all the subsequent activity into waste. xinput reattach is successful but only until next tap, which kick touch back into float.

Certainly wouldn't, because that code was merged into gnome-settings-daemon 3.15.1, which is targeted for Fedora 22.

Sam and others apparently use Fedora 21, which ships gnome-settings-daemon 3.14.x.

It might be something to do with the touchscreen mapping code. Are any of you using multiple displays?

The output of:
/usr/libexec/gnome-settings-daemon --replace --debug
will help.

after suspend the touch still works, but in a little while still disappears (moves to floating in xinput list).

xinput reattach does not help - the touchscreen drops back into floating slave right away.

> works for me, thanks

What also seems to be fixed is that the touchscreen is now properly 'attached' to its screen: on F20 (at least) when I had multiple monitors then the touchscreen would be mapped/scaled to monitors.

I don't have the issue from comment 47

Comment 49 Vitaly Bordug 2015-01-28 16:45:42 UTC
Hmm - this seems somehow to be related to multimonitor too, at least I am having random taps appearing on extra monitor when it is attached.

I will give it more testing without extra monitor.
