Subject: No pinch events with Dell laptops and Alps
Date: Thu, 16 Jul 2020 15:19:32 +0200 [thread overview]
Message-ID: <8b4907c5-4af8-2a2c-bbe1-46b2be2980be@molgen.mpg.de> (raw)
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
