using touchpad in convertible

suse_paul · October 19, 2013, 10:35am

Hi,

convertible Laptops can be used either standard way or like tablets. in the latter case they have to rely on the touchscreen.

I wonder whether opensuse can deal with that.
does anyone have experience with installing OS on such a computer?
e.g. on a lenovo yoga 11s?

how is touchscreen handling in general in OS? is there some special configuration needed, or would it work out of th ebox?

thanks
paul

I can’t answer this question from personal experience, but a quick search shows that the kernel gained multi-touch support from version 3.8 onwards.

Multi-touch (MT) Protocol
-------------------------
	Copyright (C) 2009-2010	Henrik Rydberg <rydberg@euromail.se>


Introduction
------------

In order to utilize the full power of the new multi-touch and multi-user
devices, a way to report detailed data from multiple contacts, i.e.,
objects in direct contact with the device surface, is needed.  This
document describes the multi-touch (MT) protocol which allows kernel
drivers to report details for an arbitrary number of contacts.

The protocol is divided into two types, depending on the capabilities of the
hardware. For devices handling anonymous contacts (type A), the protocol
describes how to send the raw data for all contacts to the receiver. For
devices capable of tracking identifiable contacts (type B), the protocol
describes how to send updates for individual contacts via event slots.

So, there is a good chance that openSUSE 13.1 will provide support out of the box, or else consider 12.3 with a kernel upgrade.

thanks - good to know.
so with 13.1 it’ll probably be more reliable
