Which kernel modules are needed for Elantech touchpad?

I've compiled a very minimal kernel for my system, which works just fine, I get booted into XFCE etc. and the keyboard works in the virtual consoles, but my (Elantech) touchpad does not function. Here is the lsmod from the standard kernel where the touchpad does work:

I've activated serio_raw and psmouse in the kernel, but what am I overlooking thats preventing the touchpad to work?

Sorry to bump, but I can't imagine no one knows the required kernel options for a working touchpad?

Any news on this touchpad? I've got the same touchpad, but it doesn't work at all with the synaptics drivers, and goes haywire with the default mouse drivers.

Re: Which kernel modules are needed for Elantech touchpad?

Well, mine works using the standard Arch kernel. I haven't continued trying my own kernel at the moment. My touchpad does go a bit crazy right after I boot into my desktop environment, but that clears after like 20 seconds.

Mine doesn't work period. It's always crazy. Tried to use the synaptics driver, doesn't even move.

Look at the Synaptics homepage.  IIRC there is an older synaptics driver that some people need to use for certain trackpads.  The newer Synaptics driver just fails on some laptop models too.

I found a kernel config that uses the Elantech touchpad.  It works for me.

Re: Which kernel modules are needed for Elantech touchpad?

need to bump this thread i guess.

i also have a elantech touchpad on my zepto 3215w, and ive found this: http://arjan.opmeer.net/elantech/
the only available driver for elantech touchpads for linux.

i have kernel 2.6.25-arch now, also heard theres a 2.6.26 up n coming. can this patch be implemented in these kernels in some way?
and i dont know anything about kernel stuff so.. a helping hand would be nice on how to do it if its possible.
