Installing Ubuntu 8.10 (Intrepid Ibex) on a ThinkPad X61
I installed Ubuntu 8.10 on a ThinkPad X61 model 7673-CTO.
Some available accessories for this model:
- 40Y8116 UltraBase X6
- 41N5643 Ultrabay Slim Multi-Burner III Drive
- 40Y6789 3-cell UltraBase battery
- 40Y7003 ThinkPad X60 series 8-cell High-Capacity Battery
- 40Y7696 ThinkPad and IdeaPad 65W AC Adapter
DMI info:
# dmidecode -s system-manufacturer LENOVO # dmidecode -s system-product-name 7673CTO # dmidecode -s system-version ThinkPad X61
Here is preliminary information.

Problems without solutions
No /proc/acpi/bin/dock
The file /proc/acpi/bin/dock does not exist even though the thinkpad-acpi module is loaded and the X61 is booted while docked in the UltraBase X6. So, instructions in the thinkpad-acpi README and elsewhere that make reference to this file can be followed.
lsmod reveals that the dock and bay modules are loaded. There is a /sys/devices/platform/dock.0 directory with:
# cd /sys/devices/platform/dock.0 # ls -al total 0 drwxr-xr-x 3 root root 0 2009-03-01 17:22 . drwxr-xr-x 13 root root 0 2009-03-01 17:22 .. -r--r--r-- 1 root root 4096 2009-03-01 17:22 docked -r--r--r-- 1 root root 4096 2009-03-01 17:28 flags -r--r--r-- 1 root root 4096 2009-03-01 17:28 modalias drwxr-xr-x 2 root root 0 2009-03-01 17:28 power lrwxrwxrwx 1 root root 0 2009-03-01 17:22 subsystem -> ../../../bus/platform -rw-r--r-- 1 root root 4096 2009-03-01 17:22 uevent -r--r--r-- 1 root root 4096 2009-03-01 17:28 uid --w------- 1 root root 4096 2009-03-01 17:28 undock
When not docked:
# cat /sys/devices/platform/dock.0/docked 0
When docked:
# cat /sys/devices/platform/dock.0/docked 1
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 from UltraBase
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.

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")

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.
- Instructions for showkey, acpi_listen, xev and GNOME keyboard shortcuts methods
- Instructions for input-events method
