xf86-input-mtrack's Issues

Natural scrolling option

Having a natural scrolling option like the Synaptics's driver would be awesome.

Can it be added to this driver?

Unwanted tap clicks still occur after setting "TapButton" settings to 0

I'm using Arch Linux on a 2012 MacBook Air with the xf86-input-mtrack-git package. Despite setting all TapButton settings to 0, I'm still getting extraneous tap-clicks when I leave one finger on the touchpad and touch a second finger to it. This issue can be reproduced in xinput test with one finger on the touchpad and touching a second finger to it repeatedly, causing several sequences of button press 1 immediately followed by button release 1 with several motion events between them.

I might have accidentally missed something in the config, but trying to tap with a single finger or two fingers at once causes no button presses.

Here is the output of xinput list-props:

ScrollSmooth does not work together with natural scrolling

I have configured natural scrolling by switching the binding for ScrollUpButton and ScrollDownButton.

e.g.

    Option "ScrollUpButton" "5" # 2 finger swipe up to scroll down
    Option "ScrollDownButton" "4" # 2 finger swipe down to scroll up

I find that when you have ScrollSmooth enabled this doesn't work and I assume it also interfears with the smooth scrolling causing a lot of jerkiness, since they are counterworking eachother. So I scroll down, the smooth scrolling starts and then it scrolls in the opposite direction from my actual scrolling.

Kinetic scrolling

It would be awesome if mtrack could do what synaptics/OS X do when scrolling - when the scroll gesture is fast and short, it keeps the view scrolling even after the fingers are lifted from the touchpad while putting the fingers back on the touchpad stops the scrolling.

Or is this already possible? I haven't figured out how to set that...

Btw. thanks for your new work on mtrack, good stuff!

Not working on X 1.18

I just updated to X 1.18 and at the moment I'm having to remove the mtrack driver in order for my touchpad to work.
I'm running arch on a macbook air.

Two finger scroll randomly selects texts and clicks

While scrolling with two fingers, the trackpad randomly clicks links and selects texts. It does now happen all the time, just ranomly.

I have tried to remove all tap features, since I do not need it.

Circular scrolling

One of my favorite features of the xf86-input-synaptics driver is CircularScrolling, which is a feature similar to the chiral scrolling option in some of Synaptics' drivers for Windows.
In particular, there is an excellent patent-free implementation of it available as a patch over in this GitHub project. I would be thrilled if this feature were incorporated into the mtrack driver.

touchpad speed increases when external display is plugged

Hello,
thanks for this great touchpad drivers.
I'm using it on my Lenovo X1 Carbon 5th gen, running Debian Buster.

I noticed that when I plug an external display the cursor speed increases (almost doubles).
Is there anything I can do, besides of course running a shell script that calls xinput to adjust the sensitivity when the external display is plugged?

Thanks

Two finger scroll stops working after click

Rest one finger on trackpad.
Rest thumb at bottom of trackpad, which will be ignored.
Click and release clickpad with thumb, and remove thumb from trackpad.
Rest a second finger on trackpad. There are now two fingers on the trackpad.
Move the two fingers to scroll. Scrolling does not occur. Instead, the pointer moves twice as fast.

This continues until both fingers are removed from the trackpad. I.e. you can remove a finger, then add a finger, and the issue remains.

Crashes kdeinit5

Hi there,

I'm on Arch and installed the https://aur.archlinux.org/packages/xf86-input-mtrack-git/ Pkg.

Touchpad continues to scroll when movement is not happening

When I 2-finger scroll, the scrolling continues even if I stopped the movement itself.

How can I disable this behaviour?

synaptics 3/4 finger gestures

First, thanks for the hard work in keeping this project up!

Would you consider adding handling of Synaptics' poor reporting of multitouch gestures?

As evidenced by evtest, Synaptics unfortunately reports third, and higher, tap as a sequence of BTN_TOUCH (or BTN_FINGER) followed by BTN_TOOL_TRIPLETAP (or BTN_TOOL_QUADTAP, etc...).

libinput does handle it correctly (relevant code in libinput/src/evdev-mt-touchpad.c around tp_fake_finger...) but lacks mtrack's other features, notably superb kinetic scrolling.

Thanks for the consideration!

Does this mean it's incompatible with the current 1.19.1-1 Xorg server? Or is that text from the BlueDragonX:master? I added it from the AUR but it doesn't seem to be working.

Who can tell me the meaning and usage of these options

Forgive my poor English and related knowledge, please...

What's the differences between ClickFinger and TapButton?
What's the exact meaning of the various button numbers? ( I know button 1 is a normal click, button 2 is a middle click when button 3 is a right click, BUT, what in the world are button 4 to 15 standing for? )

Any answer can be useful for me, thanks!

In absolute mode every movement should drag button one.

Every touch should "click" button one, every movement should drag it.

Config request: Add option to only set BottomEdge size

Right now there is only an option to set the edge for the whole trackpad, since I like to rest my thumb on the trackpad, or hold a finger on the button area, I need to set the Edge-option.

I have the Edge-option at 15%, this causes me to miss my scroll area on the trackpad from time to time. I Would like to set my Edge property to 15-20% for the bottom edge, and 0 for the other sides.

No left click on master

I just upgraded from v0.4.1 to master, upon which my single finger click changed to a right mouse click, and the two finger click seems to have changed to middle mouse.
This leaves me without a left mouse click option.

Hardware used is a Macbook Pro Retina 2015.

Not working

Well, i have to say, i'm quite a beginner, so beware.

tl;dr touchpad not recognized, no logs available(!?)

i cloned this git to my arch machine and did
./configure
sudo make && make install
which gave me no errors. Two files are output to /usr/local/lib/xorg/modules/input
(i also tried copying those to another directory to make X find them. yet, nothing)
Then i configured the already existing 90-libinput.conf in /usr/share/X11/xorg.conf.d according to the Readme of this git (Identifier Touchpads, driver mtrack, matchistouchpad on)

after logoff or restart, the cursor wont move. i tried to look for errors in the log, but there's no log in /var/log and journalctl _COMM=Xorg doesn't give anything either. Also $xinput list does not list the device at all. Oh Xorg -version is 1.18.

Am I doin something not quite right?

cannot seem to use left/right physical button - all are treated as left clicks

As the title said - I cannot find the settings for the physical button, and multifinger gestures are a hit-and-miss with my sweaty palms. Is there anything of which I should know?

Finger is only detected when I start the movement from the right. (solved)

If I try to move the mouse when I place my finger just a bit to the left instead of starting on the right side of the trackpad I get no movement. It will not register my finger until it has moved within the right side of the trackpad.

Thumb detection

First of all: Thank you for forking mtrack. You have fixed so many issues for me!

Maybe I'm just using wrong settings but whenever I touch the bottom edge of the trackpad with my thumb after my index finger is on the pad, the motion is stopped for a short time. Is there any way to completely ignore the bottom edge?

Below my configuration (most of it is default).

Tap drag triggers double click

Hi!
I'm very happy with mtrack so far. However, tap drag does not seem to work correctly for me. When I tap once, then touch again and move my finger, apart from dragging, it also triggers a double click. So whenever I want to move a folder in my file explorer, it gets opened because of the double click.
Is there something wrong with my configuration? Any help is appreciated.

scrolling horizontallly while scrolling vertically (and vice-verse)

As the title says - and same as rynbrd/xf86-input-mtrack#108

Only seems to be a problem when swapping the button numbers for scrolling to achieve natural scrolling. - Scrolling works as expected with the following:

    Option          "ScrollUpButton" "4"
    Option          "ScrollDownButton" "5"
    Option          "ScrollLeftButton" "6"
    Option          "ScrollRightButton" "7"

I originally commented there, but discovered that I was running this fork. Interestingly, I don't get the issue with BlueDragonX's git version, only with this version.

how to debug this?

Thanks for working on this. It appears to be the only likely option right now (in 2018) to support 3-finger drag in linux. :-(

I tried to play with v0.5 for a couple of hours but I couldn't get it to work with the master branch at all. The "swipe_to_drag" branch is slightly better as it worked about once or twice. Is there a way to debug what's going on?

Thanks!

Missing function definitions in capabilities.h, include in mtrack-test.c

Apologies if I'm not doing GitHub right (newbie), but I wanted to mention that, in attempting to build the code, I was stopped by implicit declaration warnings because capabilities.h is missing definitions for get_cap_xmin() and get_cap_ymin(). This problem was introduced in commit 6f03cc5.

I also had to include unistd.h in mtrack-test.c in order for main() to be able to make use of close(). Having corrected these two points, the code built for me.

Not sure how others have been building the code without hitting these issues, so I feel like I did something wrong, but I merely ran "./configure" and "make" per usual. Anyway, thanks for continuing to maintain this project; I desperately need it to make this MacBook usable in Ubuntu.

Vertical movement with low sensitivity is ignored

Set the sensitivity to a low value (e.g. 0.2).
Very slowly move a finger from the top-left of the trackpad to the bottom-right. Vary the speed to see the issue. At a low enough speed, the cursor will only move horizontally.

Alternatively:

Very slowly move a finger straight down. The cursor will not move at all unless you reach a certain speed. It is not possible to do this horizontally.

In both cases, the cursor appears to almost jump down in 10-20 pixel "steps" when moving slow enough. This makes it very difficult to make small movements.

The interesting part is, that if i leave the system idle for about 10 minutes before closing the lid, it will wake without segfaulting on the first key press.

Downgrading to 0.3.1 will successfully mitigate the issue.

I've uploaded the full logs of a crashing session as gist: https://gist.github.com/m4rcu5/1c4f753e799a4f9fa3b55ecb8b55c42a

Any idea what could be going on here?

Unable to unhide dock/panel

I'm trying mtrack driver for my touchpad and seams to work well, but I've noticed that I can't unhide dock/panel while I'm using it.
If I switch to libinput driver I can unhide dock normally.

i've compiled module for ubuntu 17.04
and tried to use it on my dell laptop with apple trackpad

it works, but crashes x server definitely in few minutes after start
backtrace are different each time, so it seems to be memory corruption

bcm5974/mac 4 finger swipe

Don't know if this is a hardware limitation or complete config fail but I can seem to register 4 finger anything.

I've set TapButton4 to a range of button numbers, same for the Swipe4XButton options but easystroke won't detect anything at all when trying to record the gestures (3 fingers records fine)

Any idea where I might be going wrong? I want to 4 finger swipe left/right to trigger key commands left/right

I'm using the prebuilt v0.4.1 deb on unbuntu gnome

Whenever I change settings using `10-mtrack.conf` or `xinput set-prop ...` one finger Tapping become weird

weird means, it looks like button down event triggered. But without additional move or touch, it just holding. So double tap or tap-and-slight-move needed for actual tapping.

It happens whenever I change custom option in /etc/X11/xorg.conf.d/10-mtrack.conf or using xinput set-prop.

Thanks.

Faced an issue with side/corner actions

The same issue is mentioned HERE

Button Zones do not work when thumb is resting on trackpad

I have Button Zones configured as follows (full config here)

    Option "ClickFinger1" "1"
    Option "ClickFinger2" "1"
    Option "ClickFinger3" "3"

The thirds work as expected when clicking with one finger (right third does right click)

When resting a finger on the left third of the trackpad vertically higher than the finger on the right third of the trackpad, clicking performs a right click as expected

However when resting a finger on the left third of the trackpad vertically lower than the finger on the right third of the trackpad, clicking performs a left click.

Thanks,
Evan

EDIT: Attaching xinput-props-bcm5974.txt

EDIT 2: better understanding of when clicking makes a right vs left click

implicit declaration of close() in mtrack-test.c112

Hi,

building the current git version fails.
It seems you missed importing the right lib for the function close()
Adding #include <unistd.h> to the imports solves the issue

Odd input issue

I'm part of the input group, but for some reason, whenever I try to use the mtrack driver, I get an error saying "xf86openserial: cannot open device [...] permission denied".
I don't think this is a problem with the mtrack driver though, because when I change permissions chmod g+w /dev/input/event*, it starts working again. libinput has no such problem btw.
The default permissions on /dev/input/event* are crw-r----- with root:input owner/group, does that sound about right?
However, it only works if I change it to crw-rw----.
Any advice?

Support for xorg-server 1.19.3.-2?

I'm trying to install this on my arch based laptop. Any chance of bumping the supported xorg version?

Support touchegg

Does the driver supports touchegg? If so, could you show some configuration which can give possibility to send appropriate messages to it?

High power consumption

A few months back I moved from a 2013 MBA to a 2015 MBP. On the latter, the [force] touchpad is consuming about 10W, permanently. I'm wondering if this is something you've seen, or you have any idea if it might be related to the driver or something else.

Have you had a chance to test this specific hardware? Do you know of any way to determine if this very high power usage is normal, or driver-related?

As a reference, everything aside from the touchpad uses 4W (but the touchpad alone uses 10W). On the MBA, the touchpad used an insignificant amount of power, and the computer's total power usage was about 5W.
I measure power consumption without the driver installed. That results in 5W-7W consumption, which is (even on it's worst case), 30% less.

Let me know if I can provide anything that may help triage this, totally willing to help!

Tapping enabled when multiple fingers are on touchpad

When 2 or more fingers are on the touchpad tapping gets enabled. It's reproducible by holding one finger on the touchpad and tapping with another finger.

Feature request: wait time after click to allow for movement again.

I have a MacBook Pro. Driver works great so far (thanks for your work!).

When I click the touchpad (physically clicking the touchpad as a whole), it is often accompanied with the cursor jumping a little around. After a couple of minutes testing around when it happens, I guess that this would be fixed by two new wait time options:

The time cursor movement is disabled after a click-down.
The time a tap should exist (so the time the finger should be on the touchpad) before that tap is allowed to start moving the cursor. This should be typically a very short time (I'm guessing only a couple of milliseconds).

However, I'm not sure if those wait times would be needed if the driver support speed like in OS X. There, increasing the speed of a finger causes a super-linear speedup of the cursor. So basically: moving the finger slowly allows for more precision.

(I just switched to Linux, because of some problems I had. I already tweaked this driver (the original BlueDragonX repo) before, but I'm slammed with work for school right now. If find some time, I could do it as well, but before I start, I wanted to contact you. Especially: what do you suggest to do? Will you do it? If not, but are willing to accept a Pull Request, any guidelines you want me to follow?)

Scroll with 2 fingers regardless of current motion

When I move my finger around on the trackpad (move pointer), and then at some point, put down my second finger for scrolling, it doesn't scroll, it just continues moving the pointer.

The use case is when my 2nd finger was too close to (or on) the edge to be recognized, but once my 2nd finger enters the trackpad, I would expect it to start scrolling rather than continue just moving the pointer.

This does actually already appear to happen, but there's a huge delay, more than GestureWaitTime, and it's not configurable as far as I can tell.

Moving cursor + thumb-click triggers 2-finger click

I have a Surface Book and just configured mtrack and noticed this gesture does not work as well as someone might be used to on a OS X device.

When I move the cursor with a finger and thumb-click (holding the click down, such as when highlighting text) the right-click menu shows up just as if I had done a 2-finger click on the trackpad. This is unfortunate because it means I need to lift my finger completely off the trackpad before thumb-clicking whenever I want to highlight text.

It would be a nice improvement if fingers that are in the bottom edge area were not considered part of the 2-finger click, so the finger moving the mouse does not have to come off the trackpad when clicking.

Disable h-scroll during v-scroll and vice versa

Is it possible to disable horizontal scrolling while you scroll vertically and vice versa?
This seems to be the standard behavior on OSX with two-finger scroll and is kind of easier.

It happens a lot to me, if I am using half a browser width and pages have a big horizontal scroll, that once I scroll up/down I also move left/right by accident.

Any thoughts on this?

Сonfused vertical and horizontal scroll labels

Hi,

It seems that vertical and horizontal scroll labels are confused. It causes an unpredictable scrolling in applications that use Qt framework.

When mouse enters Qt window, QXcbConnection::updateScrollingDevice function is executed (http://code.qt.io/cgit/qt/qtbase.git/tree/src/plugins/platforms/xcb/qxcbconnection_xi2.cpp?h=5.6#n860). This function enumerates evaluators, looks for valuator with valuatorAtom == QXcbAtom::RelVertScroll label and updates scrollingDevice.lastScrollPosition.

When labels are confused, the vertical scroll position is taken from valuator that tracks horizontal scroll position.

Here is a patch: alexbers@05b3176

`modprobe -r hid_apple && modprobe hid_apple` breaks driver, not sure how to restore

Possibly due to some other bug, after resuming from hibernation, one of two things happen:

Resume fails due to some inconsistency (not sure how to debug, unrelated)
Resume succeeds at which point, trackpad is working just fine, but as soon as I press any key on my keyboard, xorg crashes. Interestingly enough, I found that if I modprobe -r hid_apple && modprobe hid_apple, it stops crashing in this case.

BUT, if I run modprobe -r hid_apple && modprobe hid_apple, trackpad stops working.

Oddly, the result of running xinput indexes between the keyboard and the trackpad swap places (eg: initially keyboard at 11 and trackpad at 12, after it becomes keyboard at 12 and trackpad at 11). This interaction (as well as list-props on the trackpad field is attached below).

How do I restore the trackpad after modprobe -r hid_apple && modprobe hid_apple (and the xinput indices swap), which appears to be essential for hibernation?

Tap Drag Lock Timeout

I can't find a way to enable behaviour from libinput driver - Tap Drag Lock Timeout. Is it possible with this driver? If not could you add support for it?

Tap Drag Lock Timout is time that TapDrag waits for your finger to re-touch touchpad during tap-to-drag so that you can move things for loooong distances, selecting really long text.

The only similar behaviour I found is emulating dragging with keyboard cursor keys.
