General installation
Here comes installation instructions for Ubuntu Breezy Badger on T42 2374-ZEP.
Get a copy of Ubuntu from UbuntuLinux.org.
You should update your /etc/apt/sources.list here mine:
#deb cdrom:[Ubuntu 5.10 _Breezy Badger_ - Release i386 (20051012)]/ breezy main restricted #deb http://dk.archive.ubuntu.com/ubuntu breezy main restricted ## Uncomment the following two lines to fetch updated software from the network deb http://mirrors.dotsrc.org/ubuntu breezy main restricted universe multiverse deb-src http://mirrors.dotsrc.org/ubuntu breezy main restricted universe multiverse ## Uncomment the following two lines to fetch major bug fix updates produced ## after the final release of the distribution. deb http://mirrors.dotsrc.org/ubuntu breezy-updates main restricted universe multiverse deb-src http://mirrors.dotsrc.org/ubuntu breezy-updates main restricted universe multiverse ## Uncomment the following two lines to add software from the 'backports' ## repository. ## N.B. software from this repository may not have been tested as ## extensively as that contained in the main release, although it includes ## newer versions of some applications which may provide useful features. ## Also, please note that software in backports WILL NOT receive any review ## or updates from the Ubuntu security team. #deb http://mirrors.dotsrc.org/ubuntu breezy-backports main restricted universe multiverse #deb-src http://mirrors.dotsrc.org/ubuntu breezy-backports main restricted universe multiverse deb http://mirrors.dotsrc.org/ubuntu breezy-security main restricted universe multiverse deb-src http://mirrors.dotsrc.org/ubuntu breezy-security main restricted universe multiverse #deb ftp://ftp.nerim.net/debian-marillat/ etch main
$ sudo apt-get update
Kernel support
How to get the correct kernel:
$ sudo apt-get install linux-686
Kernel modules
TODO
|
Load the different kernel modules, and their configuration
|
ibm_acpi module:
Turning on experimental features:
/etc/modprobe.d/ibm_acpi.modprobe:
options ibm_acpi hotkey=enable,0xffff experimental=1
Starting with wireless off:
/etc/modprobe.d/ipw2100.modprobe:
options ipw2100 disable=1
ibm_acpi modules compilation
Kernel 2.6.12-9 included in Breezy only included ibm_acpi version 0.8. However a version 0.11 is available, and included in 2.6.13.

ACPI
TODO

Hibernate, suspend, buttons, lid, speedstep
|
Because of "options ipw2100 disable=1" the wireless lan is initially turned off by a software feature. The default script in Breezy does not turn on the software part. Modification to turn on wireless: /etc/acpi/wireless.sh:
#!/bin/bash # Find and enable/disable wireless devices for DEVICE in /sys/class/net/*; do if [ -d $DEVICE/wireless ]; then # $DEVICE is a wireless device. Check if it's powered on: if [ `cat $DEVICE/device/power/state` = 0 ]; then # It's powered on. Switch it off. echo -n 3 > $DEVICE/device/power/state; echo 0 else # It's powered off. Switch it on. echo -n 0 > $DEVICE/device/power/state; echo -n 0 > $DEVICE/device/rf_kill; echo 1 fi fi done

Initng
Very great initiative for optimizing the boot process. Initng
Dep packages can be found: http://alioth.debian.org/projects/pkg-initng/
Installation:
$ sudo dpkg -i initng_0.3.3-2_i386.deb
To run nice a few things and scripts need modification as follows:
Load modules on startup
Unfortunately it seems not all relevant modules are loaded automaticly when using InitNG.
Please help finding the proper scripts to do this.
Just add the proper modules to /etc/modules.
This is my list:
lp mousedev psmouse #Additional ACPI features ibm_acpi #Frequency scaling cpufreq_userspace cpufreq_powersave speedstep_centrino
Grub kernel options
To enable initng an option must be appended to the kernel load command in grub.
/boot/grub/menu.lst:
kernel /vmlinuz-2.6.12-9-686 root=/dev/hda9 ro quiet splash video=radeonfb init=/sbin/initng
Runlevel
/etc/initng/default.runlevel:

Scripts
dbus.i
daemon/dbus.i has a few faults, on Ubuntu it is "dbus" not "dbus-1"!
service daemon/dbus { need = system/initial system/mountfs system/bootmisc pid_file = /var/run/dbus/pid daemon { DAEMON=/usr/bin/dbus-daemon NAME=dbus DAEMONUSER=messagebus PIDDIR=/var/run/dbus PIDFILE=$PIDDIR/pid DESC="system message bus" if [ -e /etc/default/dbus ]; then . /etc/default/dbus fi if [ ! -d $PIDDIR ]; then mkdir -p $PIDDIR chown $DAEMONUSER $PIDDIR chgrp $DAEMONUSER $PIDDIR fi if [ -e $PIDFILE ]; then PIDDIR=/proc/$(cat $PIDFILE) if [ -d ${PIDDIR} -a "$(readlink -f ${PIDDIR}/exe)" = "${DAEMON}" ]; then echo "$DESC already started; not starting." else echo "Removing stale PID file $PIDFILE." rm -f $PIDFILE fi fi echo -n "Starting $DESC: " $DAEMON --system $PARAMS echo "$NAME." } }
hald.i
daemon/hald.i
service daemon/hald { need = system/initial system/mountfs daemon/dbus # use = daemon/acpid daemon { PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin DAEMON=/usr/sbin/hald PIDDIR=/var/run/hal NAME=hal DAEMONUSER=hal DESC="Hardware abstraction layer" if [ -f /etc/default/hal ] ; then . /etc/default/hal fi if [ ! -d $PIDDIR ]; then mkdir -p $PIDDIR chown $DAEMONUSER:$DAEMONUSER $PIDDIR fi echo -n "Starting $DESC: " $DAEMON --daemon=no $DAEMON_OPTS echo "$NAME." } }
gdm.i
daemon/gdm.i, to add locale support to the GDM login screen:
service daemon/gdm { need = system/initial system/mountfs system/hostname net/lo system/modules system/bootmisc use = daemon/xfs system/static-modules system/coldplug system/netmount # daemon = /usr/sbin/gdm # daemon = /usr/bin/gdm # daemon_args = -nodaemon daemon { PATH=/bin:/sbin:/usr/bin:/usr/sbin if [ -r /etc/default/gdm ]; then . /etc/default/gdm if [ -z "$LANG" ]; then : else export LANG fi fi gdm -nodaemon } #pid_file = /var/run/gdm.pid }
cupsd.i
Somethings wrong in the way the initNG scripts loads cups with hplip.
I did an ugly hack: daemon/cupsd
service daemon/cupsd { need = system/initial system/mountroot net/lo # use = daemon/printconf daemon/hpiod daemon/hpssd # daemon = /usr/sbin/cupsd # daemon_args = -f daemon { /etc/init.d/hplip start /etc/init.d/cupsys start } }
Helpfull tools
Rovclock
Utility to overclock and underclock the ATI radeon chip. Can be used to underclock to reduce power, especialy when on batteries.
Get it from: http://www.hasw.net/linux/
Stable clock speeds: Core: 100MHz Memory: 120Mhz for LCP only, 180Mhz when using DVI out on port replicator.
Ex:
$ sudo rovclock -c 100 -m 120
noflushd
Noflushd is a daemon that spins down disks that have not been read from
after a certain amount of time, and then prevents disk writes from
spinning them back up. It's targeted for laptops but can be used on any
computer with IDE disks. The effect is that the hard disk actually spins
down, saving you battery power, and shutting off the loudest component of
most computers.
$ sudo apt-get install noflushd
ifplugd
ifplugd is a daemon which will automatically configure your
ethernet device when a cable is plugged in and automatically
unconfigure it if the cable is pulled. This is useful on laptops with
onboard network adapters, since it will only configure the interface
when a cable is really connected.
$ sudo apt-get install ifplugd
/etc/default/ifplugd:
INTERFACES="eth0" HOTPLUG_INTERFACES="eth0" ARGS="-q -f -u0 -d10 -w -I -b" SUSPEND_ACTION="stop"
gnubiff
gnubiff is a mail notification program that checks for mail and displays headers when new mail has arrived. Has a tray icon for gnome. Supports SSL which I needed. http://gnubiff.sourceforge.net/
$ sudo apt-get install gnubiff
