= Installation of Ubuntu 6.06 Flight 6 on X60s (model 1705-24U) =
== Summary ==
=== What works out of the box ===

* Network adapter (Intel PRO/1000)
* Graphics adapter and accelerator (Intel GMA 950)
* USB
* Firewire
* Lid switch (LCD off when lid closed)
* Volume control, keyboard light and screen brightness control
* Hard disk laptop-mode (/proc/sys/vm/laptop-mode)
* LCD brightness auto-adjusts depending on AC or battery operation
* Fn buttons generate ACPI events (/var/log/acpid)

=== What needs to be fixed ===

* Dual core processor
* Wireless
* Processor frequency scaling
* Suspend to RAM
* Suspend to disk
* SD card reader
* Sound

== Installing Ubuntu 6.06 Flight 6 ==

IBM Rescue and Recovery disks (seven CDs) can be created using preinstalled Windows: All programs→ThinkVantage→Create Recovery Media. However, as long as recovery partition (called ''predesktop'' in BIOS) is left intact, system '''can be restored to factory default without having recovery CDs'''.

Ubuntu Flight 6 installer boots normally using external (USB) IBM DVD-ROM/CD-RW. SATA disk is recognised, Xorg 7.0, gdm and Gnome start normally. Xorg is configured with i810. DRI works (glxinfo|grep rendering). Networking works, eth0 uses e1000. ALSA sound worked after original installation, but at some point it stopped working as Dapper instantly had numerous updates, including kernel.

== Fixes after installation ==

=== SMP kernel ===
Flight 6 installs 2.6.15-*-386 kernel without SMP support. After installation of -686 kernel (which appears to be SMP) {{path|/proc/cpuinfo}} reports CPU0 and CPU1.

=== Wi-Fi ===
Intel 3945ABG wireless driver is available from http://ipw3945.sourceforge.net/. Wireless works after following QUICK INSTALL STEPS in provided INSTALL file. Automating driver loading works as described too, except that {{path|/etc/modprobe.d/ipw3945}} has to be used instead of the proposed {{path|/etc/modules.d/ipw3945}}.

=== CPU frequency scaling ===
After installation CPU0 switches between 1.5 GHz (full speed) and 1 GHz depending on load, but CPU1 stays at full speed. This is caused by a bug in <code>powernowd</code>, which is resolved in <code>powernowd</code> 0.97. By defaqult Flight 6 uses <code>powernowd</code> with the <code>userspace</code> governor. Changing to <code>ondemand</code> governor ({{path|/sysfs/devices/system/cpu/cpu0,1/cpufreq/scaling_governor}}) and thus using kernel part for frequency scaling (modules <code>speedstep_centrino</code> and <code>freq_table</code>) fixes this. To keep the change between reboots, install <code>sysfsutils</code> package and add the following lines to {{path|/etc/sysfs.conf}}:

devices/system/cpu/cpu0/cpufreq/scaling_governor=ondemand
devices/system/cpu/cpu1/cpufreq/scaling_governor=ondemand

<code>powernowd</code> can then be disabled from auto-starting by <code>rcconf</code>. It can also be <code>apt-get remove</code>'d, but that also wants to remove <code>ubuntu-desktop</code> metapackage.

If you do not want to change governers, uprading <code>powernowd</code> from 0.96 to 0.97 also resolves the problem. Simply download <code>powernowd</code> 0.97 [http://www.deater.net/john/powernowd.html], compile it and replace the <code>/usr/sbin/powernowd</code> executable with the version that you have just compiled, then restart powernowd:

/etc/init.d/powernowd stop
/etc/init.d/powernowd start

However be careful if the powernowd package is upgraded and the original faulty executable is replaced.

=== High pitch noise while on battery ===
X60s CPU produces the [[Problem_with_high_pitch_noises#Limit_ACPI_CPU_power_states|infamous high pitch noise]] when in lower-power ACPI states (a.k.a. C-states). To eliminate the noise maximum (i.e. lowest power) C-state had to be limited to C2. In {{path|/etc/sysfs.conf}}:

module/processor/parameters/max_cstate=2

== Unsolved ==
* Suspend to RAM (suspends, but crashes on resume)
* Suspend to disk (suspends, but crashes on resume)
* Sound
* SD card reader (driver in Linux kernel >=2.6.17)

== Not tested ==
* PCMCIA slots
* Embeded Security Subsystem (TCPA)
* Active Protection System (HDAPS)
* Modem

== Specifications ==

* Processor - Intel Core Duo 1.66GHZ
* Hard Drive - SATA 80GB - HTS541080

== Summary ==

=== What works out of the box ===
* Network adapter (Intel PRO/1000)
* Graphics adapter and accelerator (Intel GMA 950)
* USB
* Lid switch (LCD off when lid closed)
* Volume control, keyboard light and screen brightness control
* LCD brightness auto-adjusts depending on AC or battery operation
* Fn buttons generate ACPI events (/var/log/acpid)
* Sound, using the snd_hda_intel driver

=== What doesn't work out of the box===

* Suspend to ram
* Suspend to disk
* Wireless
** ''atheros driver in linux-restricted-modules-2.6.15-20-686 will not work, see below for instructions''

=== Sound ===
* The sound is very clean, loud enough and there doesn't appear to be any backround machine noise escaping through the card.

=== Annoyances ===
* '''Battery life''' - With the 8 cell battery Lenovo boasts that it gets about 8 hours of battery life. So far in Linux it is getting about 5-6. Need to mess around with more power saving options.
* The Hitachi serial ATA harddrive makes a faint but noticeable high pitched clicking sound when running off the battery.

== What works after installation ==

=== Wireless ===

* Unlike the earlier versions of the X60s this one uses the Atheros driver.
* The LED wireless indicator light does not switch on when wireless is enabled (unless you use ndiswrapper)
* The wireless toggle switch does nothing (although it appears to turn the led on momentarily)

==== compiling the madwifi drivers from source - WORKS :) ====

* untar the latest drivers from teh madwifi website - http://sourceforge.net/projects/madwifi/
* prepare build environment
apt-get install build-essential
apt-get install linux-headers-`uname-r`
apt-get install shareutils
* in the madwifi directory build and install the module
make
make install
modprobe ahc_pci

==== WPA1 encryption - WORKS :) ====
* In order for this to work you '''must''' compile the wpa_supplicant from source.
** follow these instructions carefully - http://madwifi.org/wiki/UserDocs/802.11i

==== ndiswrapper - WORKS :) ====
* Why use ndiswrapper instead? Madwifi would not allow me to connect to 5+ wireless networks I had access to. So, if you too have this problem, try ndiswrapper, if not, support open source and use madwifi.
* Download and install ndiswrapper
* Download the driver and use wine to extract it (or another machine):
** http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-52527
* Goto the WINXP_2K directory where the driver is and do the following:
ndiswrapper -i NET5211.INF
modprobe ndiswrapper
* Your wireless card should now be the wlan0 interface, and the wireless light should light up!
