Lenovo Yoga 900 ISK2

English Hardware

Hi there, I’ve installed openSuse 42.2 on this machine. And upgraded online.
Initially, touchpad and touchscreen are not working. I still couldn’t test audio, camera, bluetooth and other stuff. I’m using an USB mouse now. And KDE.

If I go to System settings > Touchpad, i see a “No touchpad found” error message.

Here, some details on the HW:

Hi, as a short update on this, both touchscreen and touchpad are working fine if I use other distros (like a Fedora Live CD).
Is there anything I should compare between both, or bring from the other distro?

If I run xinput, there’s no mousepad there, so I guess something is missing at a lower level (drivers or so).

Regards,

if its a recent laptop, and works on fedora, i would assume the older kernel in 42.2 does not have support for your hardware. you can upgrade the leap kernel to stable (tumbleweed rolling distro also has latest kernel)

Thanks! That worked ok! Just as a reference, instructions to upgrade from Leap to Tumbleweed at openSUSE:Migrate Leap to Tumbleweed - openSUSE Wiki
