Moused crashes with Synaptics

[Bertram Scharpf]

Hi,

an Acer notebook with a Synaptics Touchpad makes some trouble
here. My primary problem is: I restart the mouse daemon and then I
can move the mouse only for a short distance; suddenly the mouse
freezes.

To analyze the problem I do the following:

  # /etc/rc.d/moused restart
  # dd if=/dev/sysmouse bs=4 | xxd -c 4
  0000000: 87fb 05fb  ....
  0000004: 0687 f709  ....
  0000008: 8787 f207  ....
  000000c: 87e1 09e1  ....
  0000010: 0a87 f600  ....
  0000014: f600 87e2  ....
  0000018: f8e3 f987  ....
  000001c: f7fa f8fb  ....
  0000020: 87f3 f7f4  ....
  0000024: f887 f3f5  ....
  0000028: f3f6 87f4  ....
  000002c: f3f4 f487  ....
  0000030: f7f4 f8f5  ....
  0000034: 87fa f5fb  ....
  0000038: f587 fcf5  ....
  000003c: fdf6 87ff  ....
  0000040: f6ff f787  ....
  0000044: 01f6 02f6  ....
  0000048: 87         .
  18+1 records in
  18+1 records out
  73 bytes transferred in 21.774484 secs (3 bytes/sec)
  # 

You see: dd stops without reporting an error. Obviously the moused
doesn't work properly any more.

Further I seem to have missed something else. I found the page
http://wiki.freebsd.org/SynapticsTouchpad where are mentioned some
sysctls:

  hw.psm.synaptics_support="1"
  hw.psm.synaptics.vscroll_hor_area=1300

I don't have those ctls here and I cannot find the kernel driver
that provides them.

Does anybody have some advice for me?

Thanks in advance.

Bertram
