Pre-Installation Notes

Backup

As usual, you you have back'd up your data (you never know). Also make sure you have created the reinstallation CDs to restore the original Operating system (unless you have the reinstallation CD!)

Installation Notes

Boot Loader

install the boot loader on /dev/hdaN (to preserve Thinkpad features)

Post-Installation Notes

Power Management

ACPI:

ACPI is enabled by default on Etch's 2.6 kernel. You should load the kernel module ibm_acpi that enables some Thinkpad specific features (some "Fn" keys... http://ibm-acpi.sourceforge.net/) look my /proc/acpi/ibm 

in /etc/modules
	#Add this line, to enable some thinkpad features
	ibm_acpi

Hibernation

package: hibernation 
/etc/hibernate/common.conf 
	# enable IbmAcpi yes
	IbmAcpi yes

CPU

Processor is an : "Intel Pentium III @ 600MHz" cpuinfo ; dmi info ; cpufreq-info

Frequency scaling

package: cpufrequtils

the ondemand scheme isn't supported.

Static frequency

you have to switch manualy to performance or powserave. a userspace daemon is required (see Dynamic Frequency below). 

/etc/modules
	#Add Three lines to prepare cpu scaling
	speedstep-smi
	cpufreq_stats
	cpufreq_powersave


/etc/default/cpufrequtils
	#Add this line to configure CPUs on bootup
	ENABLE="true"
	GOVERNOR="powersave"

then run:

invoke-rc.d cpufrequtils restart

Dynamic frequency

package: cpufreqd

some tweaking is possible in /etc/cpufreqd.conf (/etc/default/cpufreqd can be left untouched)

Optionaly, gnome:

Package: gnome-cpufreq-applet

CPU Frequency Scaling Applet Panel/Right click/Add to panel/CPU Frequency Scaling Monitor

Display

Device is : "ATI Technologies Inc Rage Mobility P/M AGP 2x" 1002:4C4D

xorg.conf

X-window was properly configured automaticaly (Driver:ati). You can find my xorg.conf to use external screen... Choose the DefaultServerLayout you want.

High Resolution

The video card has only 4MB RAM (!). If your monitor can display resolution higher than 1024x768, you should keep this in mind 

#in /etc/X11/xorg.conf
#in Section "Screen", following modifications:

# let's use 16bpp
DefaultDepth    16

#Let's enable "1680x1050" at 16bpp
SubSection "Display"
	Depth           16
	Modes           "1680x1050" "1280x1024" "1280x800" "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
	Depth           24
	#on my monitor, only 1280x768 was working fine at 24bpp YMMV
	Modes           "1440x900" "1280x1024" "1280x800" "1280x768" "1024x768" "800x600" "640x480"
EndSubSection

3D / OpenGL

Installing the 3D library is fairly quick..

packages: mesa-utils xlibmesa-dri xlibmesa-gl xlibmesa-glu

Test using glxinfo or glxhead

RandR

Xwindow's "Resize and Rotate". Changing resolution works, rotation doesn't. (see gnome's Desktop Menu/Preference/Screen Resolution) Optionaly, gnome has one-click applet to R&R :

package: gnome-randr-applet | kcontrol

Sound

Device is a : "Cirrus Logic Crystal CS4281 PCI Audio" PCI 1013:6005 Which uses "Cristal 4281" module : snd_cs4281 is automatically configured

Alsa-DMix

Alsa dmix was typically required to allow sound flashplugin-nonfree v7.*. It isn"t required (for that anymore. 

/etc/asound.conf
pcm.card0 {
	type hw
	card 0
}

pcm.!default {
	type plug
	slave.pcm "dmixer"
}

pcm.dmixer {
	type dmix
	ipc_key 1025
	slave {
		pcm "hw:0,0"
		period_time 0
		period_size 2048        #1024
		buffer_size 32768       #4096
		#periods 128
		rate 48000              #44100
	}
	bindings {
		0 0
		1 1
	}
}

Keyboard

device is: Ibm's hotkeys input:1014:5450

package: hotkey-setup

Some hotkeys are working.. more work required

Hotkeys
Switch off screen (Fn-F3) yes
Suspend (Fn-F4) yes
Hibernate (Fn-F12) yes
Screen-switching at console (Fn-F7) yes
Screen-switching under Xwindow (Fn-F7) yes
Screen brightness+Thinklight yes
Sound (Volume+Mute) yes

Mouse

The Thinkpad X20 has built-in mouse : "Trackpoint"

Trackpoint

Device is : TrackPoint ( dmi info ; input:00002:000a) Trackpoint's middle button doesn't scroll by default. 

/etc/X11/xorg.conf
	Section "InputDevice"
		Identifier      "Configured Mouse"
		Driver          "mouse"
		Option          "CorePointer"
		Option          "Device"               "/dev/input/mice"
		Option          "Protocol"             "ImPS/2"

		#Comment this line out.
		#Option          "Emulate3Buttons"      "true"

		#add those three lines
		Option          "EmulateWheel"          "true"
		Option          "EmulateWheelTimeOut" "200"
		Option          "EmulateWheelButton"    "2"
		#For more information http://thinkwiki.org/wiki/How_to_configure_the_TrackPoint
	EndSection

GPM

The gpm package, which provices mouse support in console mode. Not Tested

Modem

Device is an "Agere Systems LT WinModem, Apollo 3 Mercury" (PCI 11c1:045c)

Not tested

I'm not sure if the driver to use is sl-modem or http:www.physcip.uni-stuttgart.de/heby/ltmodem/

PC Card

Thinkpad X20 comes with two PC Cards slots PCMCIA/CardBus (1 Type-II and 1 "Compact Flash" Type-I)

pcmcia

(pcmcia card are 16-bit kind of "pc-card"...)

Card Bus

(Cardbus are 32-bit kind of "pc-card" cardctl ; dmi; dmi.) package: pcmciautils

Hard Disk

This a EIDE (P-ATA) disk
