I'm not sure, I usually run pacman -Syu about 3 weeks apart and there
are usually many updates to apply.

I'm currently in the following groups:

disk - not sure why
lp - to get around printer problems
wheel - the beginners guide insisted
log - after an update destroyed my root GUI session
locate - I had some reason, can't remember now
http - facilitate editing of website
video - don't know
audio - couldn't play music until I added 
optical, storage no usbstick or cd/dvd access without it
scanner camera - same thing with camera and scanner
power - fixed a previous occurrence of this problem
users - default
wireshark - obvious

ininttab runlevel 5 ==> xdm

exec ck-launch-session startxfce4

This has been a frequently recurring problem since I first install Arch
about feb 2009, and the solution has never been the same


PS I apologize if my inherent paranoia is showing.
