Description John (J5) Palmieri 2011-02-14 19:16:28 UTC 
Description of problem:
/usr/share/X11/xorg.conf.d/50-wacom.conf contains a section for the n-trig pen driver:

N-Trig Duosense Electromagnetic Digitizer
Section "InputClass"
	Identifier "Wacom N-Trig class"
	MatchProduct "HID 1b96:0001|N-Trig Pen"
	MatchDevicePath "/dev/input/event*"
	Driver "wacom"
	Option "Button2" "3"
EndSection

This crashes my X on startup unless I comment it out.

How reproducible:

Every time I run startx or boot into runlevel 5

Steps to Reproduce:
1. run startx
  
Actual results:

Crash

Expected results:

X starts up

Additional info:

I have an N-Trig Duosense touchscreen which can be used in both multitouch input and pen input modes (the hardware should support both at the same time).

Adding this to /etc/X11/xorg.conf.d enables multitouch (the crash happens with this removed so it isn't a conflict):

Section "InputClass"
	Identifier "N-Trig Multitouch"
	MatchProduct "N-Trig MultiTouch"
	MatchDevicePath "/dev/input/event*"
	Driver "evdev"
	Option "NumberTouchPoints" "4"
EndSection
