Re: Problem/regression on ETPS elantech touchpad



2011/3/22 Pier Paolo <pierpaolo.franco@gmail.com>
  Hi all,
after last upgrade of Squeeze i am in severe troubles with my touchpad:

cat /proc/bus/input/devices | grep ETPS
N: Name="ETPS/2 Elantech Touchpad"

Without any xorg.conf.d the problem remains (no tap, unusable at all twofinger-scroll); i searched througth debian's bugs and google, but no results. It seems X reject the actual mouse1 ETPS and use a (nonexixtent?) mouse0 macintosh...

/proc/bus/input/devices:
67-I: Bus=0011 Vendor=0002 Product=000e Version=0000
68:N: Name="ETPS/2 Elantech Touchpad"
69-P: Phys=isa0060/serio1/input0
70-S: Sysfs=/devices/platform/i8042/serio1/input/input7

75-B: ABS=f0003

That's the relevant xorg.log:

Above all I can't find an usable (not "confortable" or "more usable"!) set of scrolling options... Since this upgrade the touchpad woked out of the box, and now I created a

/etc/X11/xorg.conf.d/20-touchpad.conf:
Section "InputClass"
        Identifier      "Touchpad"                      # required
        MatchIsTouchpad "yes"                           # required

        Option          "SHMConfig"             "true"

EndSection

here the last version.

In Xorg log there is indeed something veryvery strange:

actually i'm referring to the EE lines...

Someone having the same problem out there?

Glad if someone could help 
Thx, Pier Paolo.
