MultiTouch is a new feature on recent models of the X60/X61/+ Tablet. It allows you to use any device that can create pressure (such as your finger) instead of the tablet pen. This feature is currently experimentally supported with linuxwacom. However, the tablet pen will still work on such systems.
with the wacom drivers, it will only support as a single-touch interface and not as real multitouch.
If you tablet pen does not work, try building the linuxwacom modules from source. You can find everything you need at their website.
[experience from x201 tablet] Today you only get 2 fingers from the display without pressure. The pen is working normal (with pressure).
