I just installed Arch, and I like it a lot so far, but the touch screen on my Lenovo Yoga 2 11" is being recognized as a mouse. It can't recognize multitouch gestures (like with touchegg), and I see a pointer whenever I touch the screen. Here's what `xinput list` returns:
> xinput list

⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]

Here's some output of dmesg if it helps:

I never used a touchscreen but wanted to provide some thoughts.
https://wiki.archlinux.org/index.php/Lenovo_Yoga_2_11 -> "Touchscreen works out of the box with evdev. The wacom driver (package: xf86-input-wacom) may also be used, and provides two-finger right-click, scroll, and pinch to zoom. The packages easystroke or touchegg can also be used with X11 to provide further input gestures. "
https://wiki.archlinux.org/index.php/Touchegg -> if you are using touchegg, what is in your conf?
Have you tried xf86-input-wacom and/or easystroke?
Offline
I have evdev, and have also tried installing wacom, but in both cases, the screen is still treated like a mouse. On Ubuntu, touching the screen sends touch events correctly, and by running touchegg in the terminal, I can see those multitouch events appear as gestures. On Arch, however, touching the screen seems to be interpreted as a mouse event--the pointer moves, multitouch is not recognized, and touch events like pinches and swipes are not sent to applications. When I run touchegg on Arch, it doesn't recognize any touch events, and so my configuration is irrelevant, since it doesn't see that there's a multitouch device. Easystroke also doesn't solve the problem, since it's a gesture handling application, and my issue is that the touch screen is not recognized as such. What I need is some sort of command like (I'm making this up) `xinput --enable-touch-capabilities 'Atmel Atmel maXTouch Digitizer'`.

I guess I didn't understand your situation clearly. Hopefully someone with a touchscreen or knowledge about this chimes in. GL!

I have a simiar device -- a Flex 2 15 -- but the solution should be similar: you need to set your touchscreen driver to absolute mode. There is probably a synaptics or wacom config file in /etc/X11/xorg.conf.d. In that file, add the following line:
Option "Mode" "ABSOLUTE" This is what the relevant section looks like:
Section "InputClass"
Identifier "touchscreen"
Driver "wacom"
MatchIsTouchscreen "on"
MatchDevicePath "/dev/input/event1"
Option "Mode" "ABSOLUTE"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
Option "Evdev Wheel Emulation" "on"
Option "Evdev Wheel Emulation Axes" "6 7 4 5"
Option "VertTwoFingerScroll" "on"
Option "HorizTwoFingerScroll" "on"
Option "EmulateTwoFingerMinZ" "40"
Option "EmulateTwoFingerMinW" "8"
Option "CoastingSpeed" "0"
Option "VertScrollDelta" "50"
Option "HorizScrollDelta" "50"
Option "ZoomDistance" "100"Naturally, you'll want to change the device path and adjust the elements to your liking.

Hahiss, my /etc/X11/xorg.conf.d directory is empty, and adding a file there with the contents you suggested causes me to be unable to log in.
Offline
You can check: '/usr/share/X11/xorg.conf.d/' for the config file and copy it to '/etc/X11/xorg.conf.d/'
Then try to make the suggested change in the section similar to what hahiss posted
Offline
The code in hahiss' post could be slightly improved:
1. At the end there has to be an "EndSection"
2. MatchDevicePath should have event15 instead of event1 (according to your xinput-output above)
If that doesn't help: What does /var/log/Xorg.0.log say?
