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

Issues

HDAPS

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 neither Intrepid nor Jaunty (4 March 2009) includes it.

The hdaps module 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.

Docking

Do something on undock and dock

To arrange for some action to be taken on undock and dock, add an /etc/udev/rules.d/55-thinkpad-local.rules file containing the following 

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 the following: 

#!/bin/sh
DOCKED=$(cat /sys/devices/platform/dock.0/docked)
echo Docked: $DOCKED | logger -t $0
case "$DOCKED" in
        "0")
                # Do something
                ;;
        "1")
                # Do something else
                ;;
esac

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, presumably 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 other files such as /sys/devices/platform/dock.0 or /proc/acpi/ibm/bay as some suggest.

It does seem to be necessary to do this, however, before pressing the "undock" button on the UltraBase X6.

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.

No /proc/acpi/ibm/dock

The file /proc/acpi/ibm/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.

/sys/devices/platform/dock.0

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 .

--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

In Jaunty at least, doing 

echo 1 > /sys/devices/platform/dock.0/undock

does strange things. The first time I tried it it logged me out of GNOME but did not disconnect the external monitor connected to the dock. After I logged back in, the same command did cause the disconnection of the external monitor.

/proc/acpi/ibm/bay

There is a /proc/acpi/ibm/bay file with the following contents (with the X61 docked in the UltraBase X6 with a Ultrabay Slim Multi-Burner III Drive in the Ultrabay Slim port). 

# cat bay
status:         occupied
commands:       eject

Doing 

echo eject > /proc/acpi/ibm/bay

after 

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

causes the light on the drive in the Ultrabay Slim to go out.

Doing the "eject" without first doing the "delete" causes a system hang.

Keys

ThinkVantage and Zoom keys not seen by X

The ThinkVantage and Zoom keys are seen and reported by ACPI. 

$ acpi_listen
ibm/hotkey HKEY 00000080 00001018
ibm/hotkey HKEY 00000080 00001014

They are seen and reported by input-events as KEY_VENDOR and KEY_ZOOM which according to /usr/include/linux/input.h have the values 0x168 and 0x174, respectively.

They are seen by showkey as having keycodes 0x168 (360 in decimal) and 0x174 (372 in decimal) respectively.

But, in Intrepid, they aren't seen by xev.

In Jaunty (4 March 2009) the ThinkVantage key is seen by xev but the Zoom key still is not.

Steve Langasek wrote on Ubuntu bug report log 217504:
X can only handly 256 distinct keycodes due to a protocol limitation, and due to evdev the keycodes are now standardized to match the Linux input layer - with no keycode below 256 that could reasonably be substituted for KEY_ZOOM. As a workaround, you can add your own fdi file to /etc/hal/fdi/information that maps this key to a different keycode (see /usr/share/hal/fdi/information/10freedesktop/30-keymap-module-thinkpad-acpi.fdi for an example of how this is currently done).

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

Sometimes the Atheros goes braindead requiring a cold reboot. Investigating.

Getting the Wi-Fi LED to flicker (with Atheros AR5212 801.11 abg Wi-Fi)

For Intrepid, add the following lines to /etc/sysctl.conf and reboot: 

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

This does not work for Jaunty. In Jaunty there is no longer a Wi-Fi interface named wifi0; now there are interfaces wlan0 and wmaster0. Solution still being sought....

Sound and video

No beep

Solution:

  • Open Volume Control (e.g., right click on loudspeaker icon in the panel and select "Open Volume Control").
  • In Preferences, select "Beep" in "tracks to be visible" list. Close.
  • On Playback tab, unmute Beep and raise its volume control.

Sound too quiet

The problem of sound being too quiet in Hardy is not present in Intrepid.

Sound crackles

In Jaunty (4 March 2009) the welcome jingle crackles.

This problem did not affect Intrepid.

Forgets screen resolution

In Jaunty (4 March 2009) when one logs back in, dual heads are always mirrored even if they have been configured previously. Resetting or restoring the configuration does not always fully succeed and the display is not always redrawn correctly.

Suspending and resuming sometimes fixes the problem.

compiz and dual-head

The Intel Graphics Media Accelerator X3100 is limited to a maximum 3D texture size of 2048 × 2048. 

$ glxinfo -l 2>/dev/null | grep GL_MAX_TEXTURE_SIZE | sed 's/.*=[^0-9]//g'
2048

This means that compiz visual effects can only be enabled if the virtual screen area is 2048 wide/high or less. This means that if one has an external display with a width greater than 1024 pixels, it can't be located beside the laptop display if you want wobbly windows and such. E.g., a 1680 × 1050 monitor beside the X61's 1024 × 768 LCD panel would require a virtual screen that is at least 2704 pixels wide.

A wide external display can be placed above or below the laptop display, however. E.g., the above monitor placed "above" the laptop panel requires a virtual screen height of 1818 pixels. ("Above" here of course just refers to the relative position set in System | Preferences | Screen Resolution.)
