I installed Ubuntu 8.10 on a ThinkPad X61 model 7673-CTO.

Here is preliminary information.

Problems without solutions

Can't load the hdaps module

# modprobe hdaps
FATAL: Error inserting hdaps (/lib/modules/2.6.27-11-generic/kernel/drivers/hwmon/hdaps.ko): No such device or address
# rmmod thinkpad_ec
# modprobe hdaps
#

The hdaps and the thinkpad_ec module conflict. Either one can be loaded in the absence of the other.

Apparently an hdaps_ec module is needed but Ubuntu doesn't currently ship it.

The hdaps loaded: 

Setting up hdapsd (1:0.0.20070803-2) ...
 * Not starting hdapsd: /sys/block/hda/queue/protect does not exist,
 please read /usr/share/doc/hdapsd/README.Debian

The latter file says: 

hdapsd needs the hdaps kernel module and the hdaps_protect patch
in the kernel so it WON'T work out-of-the-box on a Debian machine yet.
Look at http://thinkwiki.org/wiki/HDAPS for additional information.

Problems with solutions

Hard freeze on undock

The ThinkPad X61 can be docked in the UltraBase X6 which has an Ultrabay Slim into which an optical drive can be installed such as the Ultrabay Slim Multi-Burner III Drive.

If the X61 is removed from the UltraBase then it seizes up because the kernel can no longer see the optical drive.

A sufficient solution is to "delete" the optical drive before undocking. 

echo 1 >  /sys/class/scsi_device/1:0:0:0/device/delete

It doesn't seem to be necessary to write to /sys/bus/platform/devices/dock.0/undock as some suggest.

After reattaching the UltraBase, do 

echo 0 0 0 > /sys/class/scsi_host/host1/scan

to cause the optical drive to be noticed by the kernel.

Note that it is possible that the device number be something other than 1:0:0:0. Do, e.g., 

ls -l /sys/class/scsi_device/*:0:0:0/device/delete

to check.

ThinkVantage key not seen by X

The ThinkVantage key is seen and reported by ACPI 

$ acpi_listen
ibm/hotkey HKEY 00000080 00001018

It is seen and reported by input-events as KEY_VENDOR which according to /usr/include/linux/input.h has the value 0x168.

It is seen by showkey as having keycode 0x168 (360 in decimal).

But it isn't seen by xev.

This is reportedly fixed in Jaunty.

Table of keycodes for special keys and key combinations

While investigating the above problem I researched what key codes the various special keys and key combinations generate on this ThinkPad using various tools. The observations (which haven't been double-checked yet) are summarized in the following table.

Atheros AR5212 801.11 abg Wi-Fi card doesn't resume

Solution: Add to /usr/lib/pm-utils/sleep.d/10NetworkManager: 

 	thaw|resume)
+		ifconfig wifi0 up
 		resume_nm

Getting the Wi-Fi LED to flash

Add to /etc/sysctl.conf: 

dev.wifi0.ledpin=1
dev.wifi0.softled=1

Do something on dock or undock

Add an /etc/udev/rules.d/55-thinkpad-local.rules file containing: 

KERNEL=="dock.0", ATTR{docked}=="1", RUN+="/etc/thinkpad/dock.sh 1"
KERNEL=="dock.0", ATTR{docked}=="0", RUN+="/etc/thinkpad/dock.sh 0"

and add an /etc/thinkpad/dock.sh file containing something like this: 

#!/bin/sh
# Wait for the dock state to change
sleep 1
DOCKED=$(cat /sys/devices/platform/dock.0/docked)
case "$DOCKED" in
        "0")
                xrandr -d :0.0 --output VGA --off
                ;;
        "1")
                xrandr -d :0.0 --output VGA --auto
                xrandr -d :0.0 --output LVDS --auto --right-of VGA
                ;;
esac
exit 0
