Quick power off button on Ubuntu

Here is how I permanently make the power switch/button simply shut down Ubuntu from 12.04 (no more questions asked) as root:

echo "event=button/power (PWR.||PBTN)" > /etc/acpi/events/power; echo "action=/sbin/poweroff" >> /etc/acpi/events/power; /etc/init.d/acpid restart;

König USB 300 Mbps WLAN Dongle for Ubuntu / Linux

It just works

Having tried and returned (and possibly breaking) a number of dongles i finally found one working out of the box with Ubuntu 12.04.

CMP-WNUSB40

It's really small and simple and connecting it just makes all surrounding networks visible in a flash. Had it running for a couple of hours and done numerous speed tests on bredbandskollen.se measuring some 55 Mbps (on a 100 Mbps line). Same result on a second computer (Ubuntu 11.10).

The KÖNIG (KONIG) Electronic USB 300 Mbps WLAN Dongle / Ultra compact adapter can be found in Teknikmagasinet (Gallerian, Stockholm) for 199 SKR and CDON for 219 SKR.
