Installing Ubuntu 9.10 (Karmic Koala) on a ThinkPad X61
I installed Ubuntu 9.10 on the same ThinkPad X61 that I installed Ubuntu 8.10 on last year, a model 7673-CTO.
This time I installed from DVD+R using the Ultrabay Slim Multi-Burner III Drive in the UltraBase X6.
I have since upgraded to Ubuntu 10.04 (Lucid Lynx) and there are some comments below related to that.

Problem with workaround: Kernel misdetects memory
Right at the beginning there was an important obstacle to overcome. The installed kernel would panic on boot.
I ran memtest+ from the installation disc to see if I had a memory problem. It reported errors above 4 GiB. That's odd, because I only have 4 GiB of RAM installed.
I surmised that the new kernel, version 2.6.31-14-generic-pae, errs in reckoning the amount of installed RAM. And indeed, the solution to the kernel panic was to add mem=4096M to the kernel boot parameter list.
Suspend & resume
(In Intrepid suspend & resume was unusable because the machine frequently locked up sometime after resume. Furthermore the WLAN card was unusable after resume.)
Having tried it repeatedly I can report that in Karmic suspend & resume does work more or less correctly. After resume the Atheros WLAN card is re-enabled and NetworkManager reconnects to my wireless network. That's progress!
There are still a couple of glitches, though.
- Once I had to enter my password twice on resume. The password dialog appeared as usual, with a black background, but on this one occasion it did not disappear; instead the background was replaced by the desktop which was unresponsive until I entered my password into the dialog box a second time. Weird.
- If suspended while playing an audio disk then, on resume, audio play does not continue. Instead the audio disk is detected as a new disk and the user is invited to start the music player, even though there is already a music player process running.
Docking
Docking
The ThinkPad X61 can be docked in an UltraBase X6 in which case the X61 can use the ports and drives in the UltraBase.
Undocking
Unlike with the previous versions of Ubuntu the X61 can be removed from the UltraBase X6 without danger of locking up. Formerly, drives installed in the Ultrabay had to be deleted before undocking in order to prevent a hard lockup, but now nothing has to be done to prevent a hard lockup on undock. That is progress.
It does seem, however, that the "prepare to undock" button (on the UltraBase, next to the eject lever) has to be pressed before undocking, otherwise USB devices connected to the UltraBase will not work after redocking.
After pressing the "prepare to undock" button the USB devices connected to the UltraBase and drives installed in the latter's Ultrabay cease to function—as expected. However, a monitor connected to the UltraBase's video port continues to function. The desktop remains the same size even after physical undocking; windows that were visible on the external monitor then become invisible.
I haven't done more thorough testing yet; e.g., I haven't checked to see what happens if, when undocking, volumes are mounted on devices connected to the UltraBase.
Redocking
After redocking, USB devices, external monitors and UltraBase drives work again. Nice.
Problem: Display configuration not restored on redock
However, there is a bug. After redocking the display is refreshed and the monitors do not have their original relative positions; furthermore the display appearance is different—different icons, etc.—as if the wrong theme is selected. Running System | Preferences | Appearances (without doing anything further) suffices to restore the display configuration.
Contents of /sys/devices/platform/dock.*/
Under /sys/devices/platform there are directories dock.0 through dock.3 with these contents:
/sys/devices/platform$ ls -l dock.0 total 0 -r--r--r-- 1 root root 4096 2009-11-22 18:59 docked -r--r--r-- 1 root root 4096 2009-11-22 19:22 flags -r--r--r-- 1 root root 4096 2009-11-22 19:22 modalias drwxr-xr-x 2 root root 0 2009-11-22 19:22 power lrwxrwxrwx 1 root root 0 2009-11-22 18:59 subsystem -> ../../../bus/platform -r--r--r-- 1 root root 4096 2009-11-22 19:22 type -rw-r--r-- 1 root root 4096 2009-11-22 19:59 uevent -r--r--r-- 1 root root 4096 2009-11-22 19:22 uid --w------- 1 root root 4096 2009-11-22 19:22 undock
After pressing the "prepare to undock" button on the UltraBase the content of two of the "docked" files changes.
n | type | content of docked when docked | content of docked after pressing "prepare to undock" button |
---|---|---|---|
0 | dock_station | 1 | 0 |
1 | battery_bay | 0 | 0 |
2 | ata_bay | 1 | 0 |
3 | ata_bay | 1 | 1 |
On the other hand, if the X61 is removed from the UltraBase without pressing the "prepare to undock" button the content of the docked files remains the same as when the machine was docked.

The tp-smapi module
The tp-smapi module allows, among other things, control of the battery charger as explained below.
Installing the tp-smapi module
$ sudo aptitude install tp-smapi-source $ sudo module-assistant build tp-smapi-source $ sudo module-assistant install tp-smapi-source $ sudo modprobe -a thinkpad_ec tp_smapi hdaps
This has to be done again each time a new kernel is installed.
Edit the file /etc/modules to add these lines:
thinkpad_ec tp_smapi hdaps
Ubuntu 9.10 contains version 0.40 of tp-smapi.
There is currently (19 November 2009) no hdaps-utils package in Karmic and so no hdaps-gl application.
Increasing battery life
I am advised that, to make the battery cells last longer by reducing the number and depth of charge cycles, the charge thresholds should be set as follows.
Edit /etc/sysfs.conf to add the lines:
# Make battery live longer devices/platform/smapi/BAT0/start_charge_thresh = 50 devices/platform/smapi/BAT0/stop_charge_thresh = 90
The pakage sysfsutils must be installed for using /etc/sysfs.conf.
To effect the change either reboot or do:
$ sudo su # echo 50 > /sys/devices/platform/smapi/BAT0/start_charge_thresh # echo 90 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh
Sound & modem
Sound generally works well.
The ThinkPad 56K Modem (MDC-1.5) is softmodem which collaborates somehow with the HDA sound system.
Ubuntu doesn't support the modem out of the box. Extra drivers are needed.
Linuxant drivers
What work for me are the Linuxant drivers. I had to install driver packages for both the modem (hsfmodem) and the sound hardware (alsa-driver-linuxant); specifically:
alsa-driver-linuxant_1.0.20.3_all.deb hsfmodem_7.80.02.05full_i386.deb
The drivers support 14.4 kbps as is. They support full 56 kbps and fax functionality when supplied with a license key which Linux supplies at a charge of 20 US$. I paid the money because I needed the fax functionality and I can report that faxing works well with efax-gtk.
Here is the log of the installation of the hsfmodem package:

With kernel 2.6.32-21-generic-pae, shipped with Ubuntu 10.04, the build of alsa-driver-linuxant fails.
/usr/lib/alsa-driver-linuxant/pci/asihpi/hpios_linux_kernel.c: In function ‘HpiOs_DelayMicroSeconds’: /usr/lib/alsa-driver-linuxant/pci/asihpi/hpios_linux_kernel.c:34: error: implicit declaration of function ‘schedule_timeout_uninterruptible’ make[4]: *** [/usr/lib/alsa-driver-linuxant/pci/asihpi/hpios_linux_kernel.o] Error 1 make[3]: *** [/usr/lib/alsa-driver-linuxant/pci/asihpi] Error 2 make[2]: *** [/usr/lib/alsa-driver-linuxant/pci] Error 2 make[1]: *** [_module_/usr/lib/alsa-driver-linuxant] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-2.6.32-21-generic-pae' make: *** [compile] Error 2
Solved problem: Breaks pulseaudio
When I first installed the alsa-driver-linuxant drivers, normal sound no longer worked: pulseaudio no longer recognized a sound card.
The solution was to upgrade the pulseaudio package to the latest in lucid.
Problem: No beep
After installation the system beep does not work. In Intrepid this could be fixed by starting the Volume Control application and unmuting Beep. In Karmic that application does not appear to exist so I don't know how to unmute the beep.
There was a discussion on the linux-thinkpad mailing list about this problem. It appears to have been fixed in Linux 2.6.33. Unfortunately the Linuxant version of ALSA appears to be incompatible with thinkpad-acpi, the module that creates the /proc/acpi/ibm/beep file:
$ sudo modprobe thinkpad-acpi FATAL: Error inserting thinkpad_acpi (/lib/modules/2.6.32-21-generic-pae/kernel/drivers/platform/x86/thinkpad_acpi.ko): Unknown symbol in module, or unknown parameter (see dmesg) $ dmesg | tail -2 [397468.354012] thinkpad_acpi: disagrees about version of symbol snd_card_create [397468.354014] thinkpad_acpi: Unknown symbol snd_card_create
TPM
Solved problem: Hard locks
I installed tpm-tools to see if this version of Ubuntu can talk to the TPM chip. After
sudo modprobe tpm sudo modprobe tpm_tis
the tpm_version command was enough to hardlock the system after printing out the following information:
The solution was to load the tpm_tis modules with the interrupts=0 parameter. Then tpm_version displayed the following information:
TPM 1.2 Version Info: Chip Version: 1.2.13.9 Spec Level: 2 Errata Revision: 1 TPM Vendor ID: ATML TPM Version: 01010000 Manufacturer Info: 41544d4c
