Please don't use what I said in my yesterday posting (attached below only
as reference). Loading the kmod chromebook_platform.ko makes the mouse
pointer jumping without any reason back and for to other places when
Xorg is running.
I observed and do use now:
- the cyapa EVDEV patches from December 2020, I've got from Vladimir
at that time, are in head;
- I use in ~/.xinitrc:
device="Cypress APA I2C Trackpad"
xinput set-prop "$device" "libinput Tapping Enabled" 1
xinput set-prop "$device" "libinput Natural Scrolling Enabled" 1
xinput set-prop "$device" "libinput Middle Emulation Enabled" 0
and in /etc/sysctl.conf
# Cypress Trackpad:
kern.evdev.rcpt_mask=3
debug.cyapa_enable_tapclick=3
debug.cyapa_tapclick_max_ticks=20
This gives the Trackpad working as described in cyapa(4), esp. with
this layout for taps (not clicks!):
Trackpad layout
2/3 1/3
+--------------------+------------+
| | Middle |
| | Button |
| Left | |
| Button +------------+
| | Right |
| | Button |
+--------------------+............|
| Thumb/Button Area | 15%
+---------------------------------+
In the past (December 2020) exactly this configuration gave another
layout:
+------------------------------------+
| |
| main area |
| |
| |
+------------------------------------+
| button1 | button2 | button3 | ~10mm in high
+------------------------------------+
which also was in sync with the freedesktop.org documentation:
https://wayland.freedesktop.org/libinput/doc/latest/clickpad-softbuttons.html
Why this has changed? And is there any chance to get the old layout
back, as I'm used to it :-)
Thanks
matthias
