Bug ID: 97433
Summary: ALPS touchpad edge too small
Product: Wayland
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: libinput
Assignee: [email protected]
Reporter: [email protected]
I have another dell laptop which with the new libinput stuff seems to provide a
very small area for edge scrolling. Here is the info from running:
[ola@olka linux64]$ sudo touchpad-edge-detector /dev/input/event6
[sudo] hasło użytkownika ola:
Touchpad AlpsPS/2 ALPS GlidePoint on /dev/input/event6
Move one finger around the touchpad to detect the actual edges
Kernel says: x [0..1023], y [0..767]
Touchpad sends: x [85..947], y [154..726] /^C
Touchpad has no resolution, size unknown
Calculate resolution as:
x axis: 1023/<width in mm>
y axis: 767/<height in mm>
Suggested udev rule:
# <Laptop model description goes here>
evdev:name:AlpsPS/2 ALPS
GlidePoint:dmi:bvnDellInc.:bvrA12:bd11/19/2008:svnDellInc.:pnXPSM1530:pvr:rvnDellInc.:rn:rvr:cvnDellInc.:ct8:cvr:*
EVDEV_ABS_00=85:947:<x resolution>
EVDEV_ABS_01=154:726:<y resolution>
Let me know if you need more info.
