Default install not working on Kubuntu Bionic LTS

[sylvainsab]

I am very enticed by this project. Unfortunately it seems not to work on my Kubuntu 18.04, despite running the install exactly as outlined, only a couple hours ago.

I also ran the tests, which are all PASSED : https://pastebin.com/XgevMQDk

I'm not sure what's wrong. I use all the same keyboard shortcuts as set by default, and I have tried various "threshold" values, to no avail...

How can I help you make this work under my OS ?

[sylvainsab]

After some workaround with xdotool, and reading the libinput doc, it seems it has to do with the detection of my "intended" gestures... libinput-debug-events doesn't seem to show any GESTURE_SWIPE_XXX of any kind, but rather POINTER_AXIS which I have been able to provoke. Maybe something to do with my touchpad only able to recognize so many fingers ?

@sylvainsab unfortunately, the tests are not exhaustive... they only make sure the regex will work with what libinput debug-gestures should output (ie. GESTURE_SWIPE_XXX).

Does your touchpad support multiple gestures? What driver are you using? Please print output of

xinput list | grep touchpad -i

and

lsmod | grep hid

[sylvainsab]

~$ xinput list
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                id=12   [slave  pointer  (2)]

~$ lsmod | grep hid

You're using a Mac? You might need to install additional drivers to make it work. Try checking this

[sylvainsab]

A Mac ? No, but it's interesting you raise the question. What would make you think that ? I actually use a laptop assembled by a company that used to sell computers with no OS or with Linux. Alusa - now defunct.

I'm going to try the patch.

Sorry, i was misled by your output that said mac_hid. I used to see that usually on MacBook touchpads.

In terms of your other comments, as I would point out, POINTER_AXIS is an indicator of two finger gesture (ie. Scrolling), so if you can't see GESTURE_SWIPE_XXX, then your touchpad either isn't updated or doesn't support gestures with at least 3 fingers.

You can also check out the answers from issue #23 and see if any of them work :)

Here's a summary of some of the solutions:

1. Do check if you may have not yet enabled workspaces in your Kubuntu.
   Check out this forum on how to enable multiple desktops in KDE

2. Can you print the result of

libinput list-devices | grep Touchpad -i -A 17

Output should look something like this:

Device:           Asus TouchPad
Kernel:           /dev/input/event15
Group:            7
Seat:             seat0, default
Size:             70x50mm
Capabilities:     pointer gesture
Tap-to-click:     disabled
Tap-and-drag:     enabled
Tap drag lock:    disabled
Left-handed:      disabled
Nat.scrolling:    disabled
Middle emulation: disabled
Calibration:      n/a
Scroll methods:   *two-finger edge 
Click methods:    *button-areas clickfinger 
Disable-w-typing: enabled
Accel profiles:   none
Rotation:         n/a

After this, please run

libinput debug-events --device /dev/input/event#

Replace # with the kernel from the previous output. In my case, it's /dev/input/event15.

It should show something like this:

$ libinput debug-events --device /dev/input/event15

 event15  GESTURE_SWIPE_END  +3.50s	3

If you see GESTURE_SWIPE_XXX during a finger swipe, then it should work.

3. Otherwise, the problem may lie in your keyboard shortcuts in your configurations. Type

nano /usr/local/share/comfortable-swipe/comfortable-swipe.conf

to edit your configurations. Make sure you use those supported by xdotool (see man xdotool)

OK, I read the thread and tried what you recommend : #23 (comment)

(for some reason this won't be displayed correctly...)
~$ libinput list-devices | grep Touchpad -i -A 17 Device: SynPS/2 Synaptics TouchPad Kernel: /dev/input/event6 Group: 9 Seat: seat0, default Size: 64x32mm Capabilities: pointer Tap-to-click: disabled Tap-and-drag: enabled Tap drag lock: disabled Left-handed: disabled Nat.scrolling: disabled Middle emulation: n/a Calibration: n/a Scroll methods: *two-finger edge Click methods: none Disable-w-typing: enabled Accel profiles: none Rotation: n/a

The configuration file is also good. I think the problem might come from my touchpad which would not support 3-fingers swipes, indeed there is no GESTURE_SWIPE_XXX displayed when I do the swipe gesture, only POINTER_AXIS.

Ok, closing this issue since the problem is hardware-related.
