Gutsy

Add to kernel options in /boot/grub/menu.lst:

usbcore.autosuspend=1

/etc/init.d/cupsys start

Lots of errors about lm-linear mapper: remove evms.
No acceleration in X or corrupted graphics: disable XGL by touching ~/.config/xserver-xgl/disable.

Sound

The microphone is still not working.

Install the latest alsa drivers (current version 1.0.16rc2):

Get the drivers from http://www.alsa-project.org
./configure —with-cards=hda-intel
make
sudo make install

Sleeping and hibernation

Hibernation works, using the latest fglrx drivers. On resume, keyboard is finicky due to all the spurious wireless interrupts — switch wireless card off and on using the kill-switch.
Sleeping doesn't work out of the box. Edit /etc/default/acpi-support, set `POST_VIDEO=` instead of "True". Add "ipw3945" to "MODULES".

Feisty

Everything works out of the box. Battery lifetime is still not very good (updated power-management scripts below).

Dapper tweaks

Disable ipv6 (NOW!). In /etc/modprobe.d/aliases, comment out alias net-pf-10 ipv6. In firefox, load the URL about:config, search for ipv6 and disable.
Getting firefox to share the sound card. Edit /etc/firefox/firefoxrc and change FIREFOX_DSP to "aoss".

Battery runs out quickly

Create (and make executable) /etc/acpi/ac.d/10-stefan.sh:

#!/bin/bash

echo 60 > /proc/sys/vm/swappiness
echo 3000 > /proc/sys/vm/dirty_expire_centisecs
echo 500  > /proc/sys/vm/dirty_writeback_centisecs
echo 10   > /proc/sys/vm/dirty_background_ratio
echo 40   > /proc/sys/vm/dirty_ratio

/usr/bin/aticonfig  --set-powerstate=2

/sbin/iwpriv eth1 set_power 7

cpufreq-selector -g userspace

echo "Stefan: re-enabling USB devices"
/sbin/modprobe uhci_hcd

echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo userspace > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
# of
# cpufreq-selector -g userspace

/etc/init.d/powernowd restart

Create /etc/acpi/battery.d/10-stefan.sh:

#!/bin/sh

echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo powersave > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor

echo 10 > /proc/sys/vm/swappiness

echo 95 > /proc/sys/vm/dirty_ratio

aticonfig  --set-powerstate=1

/sbin/iwpriv eth1 set_power 5

cpufreq-selector -g powersave

echo "Stefan: disabling USB devices for low power mode"
/sbin/rmmod uhci_hcd

Create /etc/acpi/resume.d/10-stefan.sh:

#!/bin/sh

/etc/init.d/powernowd restart
/etc/init.d/wifi-radar restart

Make sure laptop-mode is running (also enable in /etc/defaults/acpi-support).
Configure powernowd properly (TODO).
Ubuntu's version of powernowd does not work for Intel SMP machines. Upgrade to version 0.97 of powernowd (fixed in dapper).

Kernel complains of losing sync with touchpad

Apr 21 23:53:37 voyager kernel: [4294843.171000] psmouse.c: TouchPad at isa0060/serio4/input0 - driver resynched.

When the battery or CPU status is monitored too frequently, the touchpad loses sync. Sounds weird, but this is very common (just do a Google search).

The web suggests adding kernel option i8042.nomux. This doesn't seem to help.
The web suggests switching ACPI Embedded Controller to polling mode instead of interrupt mode) by using ec_intr=0. This doesn't seem to help.
The web suggests using psmouse.proto=imps. This kernel option doesn't exist any longer.
Disabling powernowd helps a bit, but not all that much.
Killing the CPU frequency monitor seems to help.
Put the following in /etc/modprobe.d/stefan:

   options psmouse resetafter=3 proto=imps

Sluggish keyboard

Tried kernel option irqpoll, but that doesn't seem to fix it. In fact, it seems to break CD writing.

Sound doesn't work

Should be fixed in newer versions of Ubuntu kernel (a patch has been submitted) [https://launchpad.net/distros/ubuntu/+source/alsa-driver/+bug/33719/+index]
In the meantime, unmute "Front" in the mixer and use ALSA's oss device for output.

Wireless driver installation

First, the ieee80211 stack:

Install kernel headers:

   sudo apt-get install linux-headers-`uname -r`

Install build-essential module-assistant debhelper gcc g++ libc6-dev
Download the ieee80211 stack from http://ieee80211.sourceforge.net/#downloads (NOTE: Only version .11 worked for me).
Remove old drivers:

   chmod a+x remove-old && sudo ./remove-old

Create this symlink:

   sudo ln -s /usr/src/linux-headers-`uname -r`/ /lib/modules/`uname -r`/build

   make && sudo make install

Then, the wireless drivers:

Download the ip3945 drivers from http://ipw3945.sourceforge.net/#requirements (I had to use the Intel release to get mine to work).
Install the firmware:

   cp ipw3945.ucode /lib/firmware

Install the daemon:

   cp x86/ipw3495d /sbin

Compile and install the driver with make and make install.
Create /etc/modprobe.d/ipw3945 with contents

   install ipw3945 modprobe --ignore-install ipw3945 ; sleep 0.5 ; /sbin/ipw3945d --quiet

This should start the daemon every time the module is loaded.

Run update-modules.
Remember to switch on the antennae! Otherwise, use the following script to restart wifi:

/sbin/ipw3945d --kill
rmmod ipw3945
modprobe ipw3945

ATI binary drivers installation

Note: Dapper now includes these drivers

Download ATI driver installer from https://support.ati.com/ics/support/KBAnswer.asp?questionID=3380
Install fakeroot gcc-3.4 module-assistant build-essential debhelper
Run the installer:

   X_VERSION=x690 ; fakeroot ./ati-driver-installer-<version>.run

Ask the package to generate Ubuntu packages.
Install all the produced packages.
Install the kernel module:

   sudo module-assistant build,install fglrx-kernel
