So, basically, you added your user to every group possible?

-~> disk - not sure why

You'd better figure it out.

Beginners' guide is not a bible.

Makes no sense, because your user must not touch update DB, it's the job for
cron or occasionally root.

The same as for disk.

-~> audio - couldn't play music until I added 

Totally wrong reason, since you have console-kit running.

-~> optical, storage no usbstick or cd/dvd access without it

Again, the reasoning makes no sense.

-~> scanner camera - same thing with camera and scanner

I have to check, but I don't think that you need to be a member of scanner
unless you want to scan over a network.

-~> power - fixed a previous occurrence of this problem

Membership in power lets you hibernate/suspend (pm-utils), but not
shutdown/reboot. You seem to have policykit issues.

Do you have dbus in your DAEMONS, like this:
DAEMONS=(syslog-ng microcode irqbalance cpufreq dbus...)? Otherwise xfce4 will
not work.

Because you have to clean your installation once in a while. I am quite
surprised your system even booted.
