Hi,
I installed openSUSE-13.1 (64 bit) on Dell XPS 12 Duo. All fine, expect that the touchscreen does not work.
I have the impression that udev does not reserve an input device for it…
- lsmod does not list the evdev module.
- I can load it manually, but that does not help.
At Ubuntu sul Dell XPS 12. Touchscreen e Kernel Sputnik - Notebook Italia is an Ubuntu System that works (Site is in Italy). In the Video (position 3:59) you can see that xinput has an Entry “Atmel Atmel maxTouch Digitizer”.
my xinput is the same, but without touchscreen entry 
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Integrated Webcam id=9 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)]
↳ Dell WMI hotkeys id=12 [slave keyboard (3)]

modprobe atmel_mxt_ts loads the module but nothing happens
the same with modprobe evdev
no touchscreen input device /proc/bus/input/devices
How do I convince the kernel to load the module and to use it?
Thanks for any hints
Volker
PS: at Windows 8 touchscreen works fine - but I am a linuxer and won’t use win8!
