Questions

Why is it important to turn off dynamicClocks in radeonfb in kernels before 2.6.14?

What is wrong with the wireless on/off script that comes with Breezy and is mapped to Fn-F5 out of the box? Why replace it?

Why use noflushd when Breezy comes with laptop-mode? Just enable it in /etc/default/acpi-support.

		+	Hi, with XFree86 direct rendering worked well for me. Any ideas why this isn't working with Xorg? I checked a few guides, but I found no bugs in my config, i also tried all depths and modules. Any Ideas? Maybe I overlooked something. A "it works here" would be enough for me to keep on trying, thanks, T.

		+	As it seems it is no longer neccesary to turn off dynamicClocks in radeonfb.
		+	radeonfb previously had a the same bug as in Xorg, where dynamicClock locked up some maschines. For radeonfb this lock up came randomly.
		+
		+	xorg has fixed this bug from version 6.8.3... Ubuntu ships 6.8.2.. to bad! [https://bugs.freedesktop.org/show_bug.cgi?id=2187 https://bugs.freedesktop.org/show_bug.cgi?id=2187]
		+
		+	Changing the wireless.sh script is because of the initially ipw2100 off. This is a software off, not handled by the wireless.sh script, which only handles the hardware on/off, therefore we have to turn it "on" in both hw and sw.
		+
		+	The laptop-mode included is old! It doesn't handle hdd powermanagement properly. Noflushd is very easy to install.
		+	[http://www.xs4all.nl/~bsamwel/laptop_mode/tools/index.html http://www.xs4all.nl/~bsamwel/laptop_mode/tools/index.html]
		+
		+	Instead of noflushd I suggest you use laptop-mode-tools which is newer and actually works.
		+
		+	Good idea with the bluetooth. Right now Breezy turns both blutooth and wireless on/off with Fn-F5.

		+	== Using Fn-F6 to enable/disable Bluetooth ==
		+
		+	First, to make sure Fn-F6 is available as a hotkey, either do
		+
		+	echo 0xffff > /proc/acpi/ibm/hotkey
		+
		+	(this will work until next reboot or suspend), or change the mask in /etc/modprobe.d/ibm_acpi.modprobe.
		+
		+	Next, create a shell script /etc/acpi/bluetooth.sh:
		+
		+	#!/bin/bash
		+	# Enable/disable builtin Bluetooth on IBM Thinkpads
		+	if grep -q enabled /proc/acpi/ibm/bluetooth; then
		+	echo disable > /proc/acpi/ibm/bluetooth
		+	else
		+	echo enable > /proc/acpi/ibm/bluetooth
		+	fi
		+
		+	Next, create an event file /etc/acpi/events/ibm-bluetooth
		+
		+	# This is called when the user presses Fn-F6 button and calls
		+	# /etc/acpi/bluetooth.sh for further processing.
		+	event=ibm/hotkey HKEY 00000080 00001006
		+	action=/etc/acpi/bluetooth.sh
