            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: wayland-bugs at lists.freedesktop.org
          Reporter: nacho.resa at gmail.com

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 at 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.
