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

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.

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

Again, the reasoning makes no sense.

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

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