Lenovo L430 Elantech touchpad problems

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


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:

Nov 3 20:37:29 l430kl kernel: [ 890.307107] psmouse serio1: elantech: assuming hardware version 3 (with firmware version 0x350f02) Nov 3 20:37:29 l430kl kernel: [ 890.320581] psmouse serio1: elantech: Synaptics capabilities query result 0xb9, 0x15, 0x0c.

$

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
