Touchscreen support in openSUSE 13.1 / KDE?

I’ve installed openSUSE 13.1 on an HP Envy 15 laptop with TouchSmart touch screen. It works as a simple mouse-equivalent, but that’s all - no multitouch, no click-and-drag, etc. Is there a way to get real touchscreen support working?

It looks like my HP Envy 15 has an EETi/eGalax touchscreen (at Bus 007):

Bus 007 Device 002: ID 0eef:a103 D-WAV Scientific Co., Ltd 
Bus 008 Device 002: ID 138a:0050 Validity Sensors, Inc.

From searches online I found this driver:

When I try running the provided I get an error:

(I) Found /etc/init.d/boot.local file.
(I) Found a HID compliant touch controller.
(I) X.Org X server 1).1).1)
./ line 833: : 1): integer expression expected
./ line 833: : 1): integer expression expected
(W) X version is below 1.7.6.

but “Xorg -version” says “”.

From the installation instructions it looks like I need to rebuild the kernel, something I haven’t done in a few years, but the instructions are somewhat confusing. Anybody have any experience with this driver?
