Hello everybody.
I am trying to get the touchscreen on an DELL Inspiron One AiO-PC working under linux.
So far i tried different systems/kernels and at the moment i am using an archlinux live cd.
The problem is, that the screen is recognized as an usb-device (see output from lsusb & /proc), but does not appear as a device in /dev/input/.
here is some information:
[root@archiso arch]# lsmod | egrep 'usb|evdev'

Everything i found on the web regarding NextWindow-Screens and getting them to work under linux refers to the USB Vendor:Product ID 1926:0003, but not 1926:007a (the one in the DELL-PC).
What i would like to know is:
Is there any chance to get this thing to work or do i have to give up because of the fact that the touchscreen is not recognized as an input-device?
I appreciate every help, advice, suggestions!
greetings

Hi there.
For all users who have similar problems and found this thread:
I stumbled upon this launchpad bug report, which mentions a prototype driver [nwfermi] provided by the NextWindow support.
With Ubuntu 10.04. Server I was able to get the touchscreen to work with single-touch functionality.
Therefore I mark this thread as solved.
