Dear Linux folks,
On the Dell Latitude E7250 and Dell Precision 3340 I fail to get three
finger pinch events generated needed for GNOME Shell gestures [1].
Debian Sid/unstable with Linux 5.7.6 is running on these systems.
[ 1.602394] input: AlpsPS/2 ALPS GlidePoint as
/devices/platform/i8042/serio1/input/input2
I am only able to create swipe events. (Four finger swipe works to
switch workspaces.)
```
$ sudo libinput debug-events
[…]
-event1 DEVICE_ADDED AlpsPS/2 ALPS GlidePoint seat0
default group10 cap:pg size 98x51mm tap(dl off) left scroll-nat
scroll-2fg-edge dwt-on
-event2 DEVICE_ADDED DELL Wireless hotkeys seat0
default group11 cap:k
event1 - AlpsPS/2 ALPS GlidePoint: kernel bug: Wrong slot count (4),
reducing to 2
-event1 GESTURE_SWIPE_BEGIN +1.549s 3
event1 GESTURE_SWIPE_UPDATE +1.549s 3 -0.36/ 0.26 (-2.59/ 1.85
unaccelerated)
[…]
```
Does the hardware and driver support that?
Kind regards,
Paul

The device is an Alps GlidePoint which are usually INPUT_PROP_SEMI_MT. On
those devices, we don't support 3fg pinch gestures because we don't get
enough data to make the gestures reliable. There is no specific quirk for
your device otherwise, afaict.
If it's not semi-mt then it's too hard to say without more data, I'll need
at least the output from libinput record to figure out why (that recording
will contain the libinput version which also matters).
Cheers,
Peter

Thank you for your reply, and the explanation.
Four finger gestures seem to work. At least in GNOME Shell workspaces
can be switched with that.

Sorry for omitting that. It’s 1.16.1 now. I uploaded the logs [2].
Kind regards,
Paul

thanks. based on the log, it's not a semi-mt touchpad and has 5 slots. So gestures
should work in theory, let's move this to a libinput bug please and continue
there: https://gitlab.freedesktop.org/libinput/libinput/issues
Cheers,
Peter

Thank you for your reply. I created issue #519 [1].
