PostPosted: Sat Aug 11, 2018 1:37 pm    Post subject: elantech touchpad Reply with quote

I'm having trouble getting my touchpad to work.
I believe it is the ITE Tech. Inc. ITE Device(8910).
But it appears that the kernel is detecting it as a keyboard and a mouse..?
And the elantech modules I compiled were not loaded on startup which was a bit weird. I'm not using an initramfs.

Code:

Device drivers --->
    Input device support --->
        PS/2 mouse --->
            [*] Elantech PS/2 protocol extension
        <M> ELAN I2C Touchpad support
        [*] Enable I2C support
        [*] Enable SMbus support
    [*] HID support --->
        Special HID drivers --->
            <M> ELAN USB Touchpad Support

The ITE8910 is a problematic device, initial support for that is only in kernel 4.17 but then it will freeze regularly:
https://bugzilla.redhat.com/show_bug.cgi?id=1543769
The keybord shows up because it was initially meant as a composite device for small notebooks providing both touchpad and keyboard interface. Can be ignored.

So I guess support for this hardware is super buggy. But I see some people who have it working.
Not sure what kernel config they had though. :x
