2.6.13-rc1-mm1 -- Synaptics touchpad not detected correctly

[Miles Lane]

Hello,

Any ideas why my Synaptics touchpad isn't getting recognized
as supporting multi-finger tap detection?  I haven't seen detection
work with earlier kernels, either.  However, multifinger taps work
under WinXP.

dmesg is reporting:

           Synaptics Touchpad, model: 1, fw: 5.10, id: 0x258eb1, caps:
0xa04713/0x0
           input: SynPS/2 Synaptics TouchPad on isa0060/serio1

On the web, I found this reference:
http://www.softwarelibremorelos.gob.mx/pipermail/slm/2005-March/001267.html
Which, for 2.6.10, shows:
           Synaptics Touchpad, model: 1
            Firmware: 5.10
            Sensor: 37
            new absolute packet format
            Touchpad has extended capability bits
            -> multifinger detection
            -> palm detection
           input: SynPS/2 Synaptics TouchPad on isa0060/serio1

My .config contains:

CONFIG_INPUT_MOUSEDEV=y

It looks like it is recognized. Bit 1 in the caps word tells if the
touchpad supports multi-finger detection. Earlier kernels used to
report this in plain text form, but it was considered bloating dmesg
unnecessarily, so now you only get the raw capability bits reported.

Anyway, you also need to use the X driver from

        http://web.telia.com/~u89404340/touchpad/index.html

to take advantage of multi-finger taps. The kernel itself doesn't bind
any special actions to them.
