Lenovo L430 Elantech touchpad problems

[Keith Lawson <lawsonk@libertas-tech.com>]

Hello,

I'm running Debian 6.0.6 (Squeeze) on a Lenovo L430 and having issues 
with the trackpad and trackpoint. Originally I was running 3.0.4 built 
from source and the track pad was detected as a PS2 mouse. The pad 
worked but I wasn't able to control the advance track pad functionality, 
specifically I want to disable the "tap to click".

I tried 3.6.3 with no luck, just upgraded to 3.6.5 today and I'm still 
having the same problem.

psmouse recognizes the device as an Elantech touchpad and X sees the 
device:

modprobe psmouse log:

The track pad functions now and "xinput list-props" sees the touchpad 
settings but now the touchpoint (eraser head) and 3 mouse buttons above 
the track pad don't function. Moving the eraser head or clicking on the 
3 mouse buttons above the touchpad produce the following errors in 
messages over and over:

Any help would be appreciated. I see lots of Ubuntu bugs about these 
trackpads freezing after suspend/resume and read a recent thread on this 
mailing list from Nicola Alessi but those seem to be different issues.

Thanks,

Keith
