I'm assuming that when I touch the touchpad, this should NOT happen.

There is a bigger picture here and that is when my palm rests too heavy on the touchpad, it messes with the clicking of my mouse.  I'll grab tabs and scroll bars and won't let go until I click on them again.

I can reproduce this by putting 3 fingers on the touchpad and clicking on a scoll bar or tab and it will start messing up in short order.
Comment 1 Peter Hutterer 2017-05-09 02:42:33 UTC 
libinput-debug-events is unrelated to the gnome session, it creates a new context and the gnome settings have no effect on it.

is this in an X session? If so, what does xinput list-props "SynPS/2 Synaptics TouchPad" show after disabling the touchpad in gnome?

for the palm issues, etc. please file a separate bug, thanks.
Comment 2 Matt Jamison 2017-05-09 12:45:38 UTC 
Yes, this in an X session.

$ xinput list-props "SynPS/2 Synaptics TouchPad"
unable to find device SynPS/2 Synaptics TouchPad

will be filing seperate bug for other issues.

thanks.
Comment 3 Peter Hutterer 2017-05-09 22:48:56 UTC 
run xinput list to find the device name, I wonder if I mistyped anything. then substitute the device name with the one for the touchpad. if you see devices like "wayland pointer" etc, then you're under wayland, in which case the xinput approach won't work. log out and back in as Gnome on Xorg on the user's login screen (click the gear icon), then see if you can reproduce it there.

Comment 5 Peter Hutterer 2017-05-10 04:38:15 UTC 
You're using the evdev driver and that usually means that the touchpad uses the synaptics driver. Both are effectively deprecated now, and gnome has dropped support for those so the gnome checkbox does nothing but look pretty.

Not sure why you're using evdev for the touchpad, do you have xorg-x11-drv-libinput installed? Check /etc/X11/xorg.conf.d for any leftover snippets, remove any mate or cinnamon packages if you have any.
Comment 6 Peter Hutterer 2017-05-10 08:56:24 UTC 
also, is this still an issue now that you tried out 1.7.2? (see bug #1433033)
Comment 7 Matt Jamison 2017-05-10 12:12:59 UTC 
I pulled the latest libinput out of rawhide.  I don't see 1.7.2 as you mentioned.  am I missing something?

# rpm -qa |grep libinput
libinput-1.7.1-4.fc27.x86_64
xorg-x11-drv-libinput-0.25.1-1.fc27.x86_64


# rpm -qa |grep synaptic
#

# rpm -qa |grep evdev
libevdev-1.5.6-1.fc25.x86_64
xorg-x11-drv-evdev-2.10.5-1.fc25.x86_64


# rpm -e libevdev xorg-x11-drv-evdev
error: Failed dependencies:
	libevdev.so.2()(64bit) is needed by (installed) libinput-1.7.1-4.fc27.x86_64
	libevdev.so.2(LIBEVDEV_1)(64bit) is needed by (installed) libinput-1.7.1-4.fc27.x86_64

# ls /etc/X11/xorg.conf.d/
00-keyboard.conf

Problem exists in both wayland and X11.
Comment 8 Peter Hutterer 2017-05-15 01:22:23 UTC 
(In reply to Matt Jamison from comment #7)

should definitely be there, maybe some mirror issue?
https://koji.fedoraproject.org/koji/buildinfo?buildID=888012

> # rpm -e libevdev xorg-x11-drv-evdev
> error: Failed dependencies:

libevdev is a low-level library that libinput uses as well, if anything only
remove xorg-x11-drv-evdev. but witout any config snippet you should be able
to just leave it there, libinput will override it anyway.
 
> Problem exists in both wayland and X11.

in the X session: do xinput watch-props "touchpad device name" and toggle the touchpad off setting in gnome, does anything change?
Comment 9 Matt Jamison 2017-05-17 16:08:36 UTC 
problem still persists with no change.

putting 3 fingers on the disabled touchpad still messes up clicking.

I don't see a touchpad device name to run xinput watch-props on.
Comment 10 Peter Hutterer 2017-05-23 00:23:19 UTC 
You're running under wayland, where xinput will have no real effect. You need to start an X session to be able to debug this.
Comment 11 Vladyslav Shtabovenko 2017-05-23 17:54:17 UTC 
I can confirm this bug on the same configuration (Fedora 25 and T460p). 

The only way to really turn off the touchpad is to issue

$ xinput set-prop 'SynPS/2 Synaptics TouchPad' 'Device Enabled' 0

I'm using X session (not Wayland), so for me this always works.

Could it be that our touchpads have different firmware versions? What I have is

Comment 14 Matt Jamison 2017-05-24 13:53:46 UTC 
Everything is about the same.  I have an updated BIOS, but the real question is:
can you replicate my issue.  The issue isn't that the touchpad is enabled or disabled.  I can't click or use it to scroll at all, aka: disabled.

My issue is that when I out 3 fingers on the touchpad then go click on something.  Sometimes it works, sometimes it doesn't, and sometimes it acts as if I just grabbed whatever it is that I clicked on.

I replicate this by clicking on a scroll bar of a browser or a terminal window while I have 3 finger placed on the disabled trackpad.

You may ask: why in the world would someone ever put 3 fingers on a trackpad then try to click?  Well, I have larger hands and often times, part of my hand rests on the trackpad and REALLY screws up things.

Please let me know if you can replicate this on your t460p.

Comment 15 Vladyslav Shtabovenko 2017-05-24 16:02:34 UTC 
Ok, now I see your problem, To be honest, so far I never
tried to put three fingers on the disabled touchpad and then
issue a click using the trackpoint or an external mouse.

I did it right now and it behaves exactly the way you 
wrote: "Sometimes it works, sometimes it doesn't, and sometimes
it acts as if I just grabbed whatever it is that I clicked on."

So yes, I can reproduce this on my T460p. 

Now that I payed more attention to it, it appears that when I 
use the trackpoint (I'm left-handed), my hand always floats above
the trackpad but never lies directly on it. For the record, I also
have larger hands (but perhaps not as large as yours). I guess this
is the reason why I never encountered this issue. Of course, the
hand position is always a very individual thing, so there are definitely
no "right" or "wrong" ways to use the trackpoint...

In any case, it is weird that that the touchpad input is still somehow
evaluated once it was explicitly disabled. I don't think that this 
is how it is supposed to be.

Having said that, I guess part of the issue is that on ThinkPads in general,
the touchpad and the trackpoint are not two separate entities but rather
one piece of hardware. For example, on a T460p the signal from the trackpoint 
stick is transferred via the cable that connects the keyboard to the mainboard.
However, the signal from the trackpoint buttons is routed via the same cable
that connects the touchpad to the mobo.
Comment 16 Peter Hutterer 2017-06-02 02:02:11 UTC 
There are a few issues here that are tangentially related. Please don't submit anymore dmidecode data, it only makes it harder to find the signal in all the noise.

First: libinput-debug-events sits on the side of the X session, it sees the same events but behaves differently because it doesn't see the configuration from X. Think of it of running tail -f on the same file twice, the two instances see the same data but can behave differently depending on what other options are applied.

libinput-debug-events is useful to tell when a bug is caused by libinput, but it doesn't always help with X-specific bugs.

To debug this, we will need an X session and the output of variuos xinput commands, anything else won't help much.

Ok, now let's continue: 
	Device Enabled (139):	0

that means the device is disabled at the X level and removes it from the fd set for libinput. The server won't forward any events from a device, even if it did send events to begin with (which it shouldn't, because it was removed). Judging by comment 11, this seems to work.

GNOME toggles the "libinput Send Events Mode Enabled" property to 1 0 (== disabled). That works here (F26 though) but I'll need a confirmation from you that it does that. If not, then this is a gnome issue.

xinput watch-props "Synaptics...", then toggle the checkbox in the control center and see if the value changes.

If it *does* change to 1 0 but the touchpad still generates events, please run
xinput test-xi2 and see what events are actually generated on the X level by the touchpad (keep an eye on the device id in (parenthesis) to identify the touchpad). Let me know how you go with these.
Comment 17 Matt Jamison 2017-06-05 19:51:54 UTC 
All touchpad options aren't in the control panel anymore.  I just have:
General: primary button -> left/right
Mouse: Mouse speed, Natural Scrolling: on/off

xinput test-xi2 produces the same results.  I put 3 fingers on the touchpad which doesn't register anything in the logs, but when I go to click the mouse button, sometimes it works, sometimes it doesn't, and sometimes it register the button press but not release.

I'm having a hard time trying to get data when nothing is being registered in any of the logs.  It's simply doesn't register any click when I press the mouse button.
Comment 18 Peter Hutterer 2017-06-06 03:11:22 UTC 
you're still using the synaptics driver? if you do an xinput list-props "device name", are the devices prefixed with Synaptics? or still Evdev like in comment #4? If so, you need to switch to the libinput driver. see comment #5. If you have ever had a mate or cinnamon package installed, that could be the reason, they unconditionally overwrite (or used to overwrite) the normal configuration. Look for any symlinks in /etc/X11/xorg.conf.d/

Comment 20 Peter Hutterer 2017-06-13 02:54:39 UTC 
well, that's me out of ideas then. libinput driver is being used, I don't know why gnome wouldn't show the touchpad configuration. GNOME *does* disable the touchpad, see libinput Send Events Mode Enabled (260):	1, 0 which indicates that at least mutter is aware of the libinput driver.

With the property set, libinput *should* ignore the touchpad events, I don't know why it doesn't. And we don't have any other debugging tools yet for that specific use-case. Sorry, I really don't know how to debug this further remotely.
Comment 23 Michael Epley 2017-08-24 18:06:17 UTC 
I'm also encountering this issue on current F26+Wayland / Thinkpad P50. Appears to happen on all power state changes, cycling the touchpad enable via gnome settings panel/controls temporarily resets the touchpad.

My apologies for the late response.

Yes, I have rebooted and there is no change.  I also got the latest BIOS update from Lenovo and installed that.

The problem still persists and the mouse still works at the login screen even though it's turned off in the BIOS.
