>Number: 1827
>Category: bin
>Synopsis: add support of Glidepoint trackpad "tap/drag" to moused
>Confidential: no
>Severity: non-critical
>Priority: low
>Responsible: freebsd-bugs
>State: open
>Class: change-request

>Last-Modified:
>Originator: Louis Mamakos
>Organization:
part-time freebsd hacker
>Release: FreeBSD 2.2-CURRENT i386
>Environment:
XFree86, with Glidepoint Trackpad pointing device, or Glidepoint Trackpad
keyboard with integral pointing device.
>Description:
The Glidepoint pointing device, available from Alps and other vendors
is compatible with a PS/2 mouse. Unlike a mouse or a trackball, you
move your finger around on a rectangular a surface which causes
pointing device motion. The device is also equipped (depending on
the model and manufacturer) two or three mouse buttons. Additionally,
the user can "tap" the pointing surface.
The Trackpad pointing device has a "tap" and "drag" feature where
a tap gesture is reported to the driver and should be interpreted as
a single click of the left button. A "double-tap and drag" should
be treated as moving the pointing device with the left button held
down.
It's much nicer to use than to describe...
I reverse engineered this behavior of the device a while ago, and
made similar modifications to the XFree86 server. No proprietary
or confidential information was obtained from the manufacturer.
Also, please note that moused requires the use of the non-blocking
version of the mouse device. For the PS/2 driver, this requires
having MINOR(dev)==0 rather than 1 as it is now. I hestitate to
modify the MAKEDEV script as this would break existing users of
/dev/psm0. My /dev looks like this:
crw------- 1 root wheel 21, 1 Oct 16 22:26 /dev/npsm0
crw------- 1 root wheel 21, 0 Oct 16 22:26 /dev/psm0
where moused would use /dev/psm0, and the X server (while not
using moused) would use /dev/npsm0.
Also, the moused usage message can be automatically generated
rather than hardcoded.
>How-To-Repeat:
Own one of these things, and wonder why it works so much better in
Windows than under X.
>Fix:
Apply these diffs to moused(8), and the sysconfig script:
