Installing Ubuntu 9.10 (Karmic Koala) on a ThinkPad X61

From ThinkWiki
Jump to: navigation, search

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 ThinkPad X6 UltraBase.

I have since upgraded to Ubuntu 10.04 (Lucid Lynx), to 10.10 (Maverick Meerkat) and to 11.04 (Natty Narwhal) but I haven't rechecked everything I wrote here after installing 9.10.

ThinkPad X61

In August 2011 I upgraded the system program to version 2.22 7NETC2WW dated 2011-03-22; embedded controller firmware version 1.03. I did this with a bootable CD (7nuj22uc.iso) in the X6 UltraBase.

Kernel

Worked-around problem: 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 & undocking

Docking

The ThinkPad X61 can be docked in an ThinkPad X6 UltraBase 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 X6 UltraBase 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

--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.

content of /sys/devices/platform/dock.n/ files
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.

Problem: Zoom key not seen by X

The "Zoom" key (Fn-Space) cannot be assigned a function in GNOME. As shown in the table the key combination is seen and reported by ACPI

$ acpi_listen
ibm/hotkey HKEY 00000080 00001014

but there is no corresponding X event.

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.

The bug has been reported but there has not been any progress made (as of October 2010).

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 rmmod hdaps # To remove factory hdaps module
$ 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 through 10.10 contain version 0.40 of tp-smapi. On 10.10:

$ uname -a
Linux triffid 2.6.35-22-generic-pae #34-Ubuntu SMP Sun Oct 10 11:03:48 UTC 2010 i686 GNU/Linux

There is currently (10 October 2010) 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 Linuxant 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:

Solved problem: Linuxant ALSA doesn't build with Lucid's kernel

With kernel 2.6.32-21-generic-pae, shipped with Ubuntu 10.04 (Lucid Lynx), 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’

This was fixed in version 1.0.23.0 of alsa-driver-linuxant.

Problem: Linuxant ALSA doesn't build with Maverick's kernel

With Maverick's kernel 2.6.35-22-generic-pae the build of alsa-driver-linuxant version 1.0.23.0 fails with

Solved problem: Linuxant ALSA 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 version included in lucid.

Partially solved problem: No beep

After installation the system beep does not work. E.g., ringing the terminal bell with echo -e '\a' (under bash) has no effect. The problem has been thoroughly discussed in this Ubuntu bug report. The short story is that a host of bugs have prevented the system beep from working by default in recent Ubuntu releases.

Fix for GNOME Terminal

In natty it is necessary to do the following in order to have the terminal bell played through X, the window manager and pulseaudio:

pactl upload-sample /usr/share/sounds/gnome/default/alerts/glass.ogg bell.ogg
xset b 100

To automate these commands:

  • Put the pactl command in ~/.xprofile.
  • From a terminal run gconf-editor and at "desktop | gnome | peripherals | keyboard" change "bell_mode" from "off" to "on". This seems to have the same effect as xset b 50.

If you still don't hear the terminal bell make sure that sound output volume is turned up high enough and that in the GNOME Terminal menu, "Edit | Profile Preferences | General | Terminal bell" is ticked.

Don't put anything in .xinitrc or .xsession—they are no longer executed on Ubuntu. Don't put an xset command in .profile—it gets executed too early.

Fix for console terminal

(The console terminal is accessible from the GUI by pressing CTRL-ALT-F1.)

The console terminal bell plays without intervention of X. It requires the pcspkr driver but by default this is blacklisted. To un-blacklist it, comment out or remove the line "blacklist pcspkr" in /etc/modprobe.d/blacklist.conf. The module will be loaded on boot; to load it immediately do modprobe pcspkr.

A hitch

Unfortunately, alsa-driver-linuxant, 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

The X61 has a treacherous platform module (TPM) chip.

Solved problem: Hard locks

I installed tpm-tools to see if this version of Ubuntu can talk to the 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:

Tpm version hardlock.jpg

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

Fan

The machine started overheating. To fix this I created a file /etc/modprobe.d/thinkpad-acpi.conf with:

options thinkpad-acpi fan_control=1

and did

echo level 7 > /proc/acpi/ibm/fan 

as suggested at How to control fan speed.
