[Pkg-gpm-devel] Bug#321845: Alps touchpad tapping remap fails in gpm

[David Liontooth]

Package: gpm
Version: 1.19.6-20
Severity: normal


In brief, gpm's "-g 2" switch in for remapping tapping to the middle key
isn't working for my Alps touchpad, which makes it hard to interoperate
with an external three-button mouse.

The Alps Glidepoint (on a vpr matrix 200a5) is correctly detected when
the psmouse module is loaded:

alps.c: Enabling hardware tapping
input: PS/2 Mouse on isa0060/serio1
input: AlpsPS/2 ALPS GlidePoint on isa0060/serio1

In KDE's touchpad control panel, I can map tapping to the middle button
and paste works. (Incidentally, how do I do this in the x-windows
configuration file, so that I can use the touchpad for pasting in other
window managers, such as icewm?) However, the remapping function in gpm,
"-g 2", fails.

gpm's man page says to use "-g 2" to map tapping to the middle button,
but it has no effect on tapping. When I run /etc/init.d/gpm with the -xv
switch, I see

++ start-stop-daemon --start --quiet --nicelevel 0 --exec /usr/sbin/gpm
-- -m /dev/psaux -t autops2 -Rms3 -g 2

Other "append" commands work fine, for instance "-B 321".

Incidentally, gpm-mouse-test refuses to proceed past the "Detecting the
packet size" stage.

The synps2 type does not work (no response). The device
/dev/input/events3, which is used to identify the touchpad in x-windows,
doesn't work (no response).

Configuration file, /etc/gpm.conf:

device=/dev/psaux
type=autops2
repeat_type=ms3
append="-g 2"

On starting gpm, left button selects and right button pastes.

If I plug in a second mouse, an imps2, and press the middle button once,
then the touchpad's right button gets remapped to extend selection,
leaving me with no paste function. Using the "-2" switch works -- it
forces the mouse into two-button mode, so I lose the "extend selection"
function, but retain paste on both. A remap would be a lot better.

mev details below -- everything looks fine, except tapping maps to
button 1 instead of the far more useful button 2.

The problem is that tapping is mapped to button 1 (left) instead of
button 2 (middle), so there is no "button 2", as I get with an external
imps2 mouse:

mouse: event 0x14, at 39,12 (delta  0, 0), buttons 2, modifiers 0x00
mouse: event 0x18, at 39,12 (delta  0, 0), buttons 2, modifiers 0x00
