PC: Overview of the Linux related features of the Lenovo ThinkPad T61

Table of contents

1. Preface

This is a quick survey about Linux related hardware features of the Lenovo ThinkPad T61. I don't try to explain the usual installation details (for instance, which partitions I have made, what they are good for and so on and so on...). Requests for additional information may be directed by eMail to the author.

The laptop comes with an 15.4" WSXGA+ TFT LCD, which allows resolutions from "1680x1050" or "1280x800" pixels.

A nice goodie is the facility to boot the notebook over USB and LAN (not needed here yet, but a nice to have feature).

The machine comes with an ACPI interface. Standby- or suspend-mode is established by software (stock Linux acpi utilities) or pressing the appropriate hardware button. The laptop suspends under X and console to RAM and Disk. It restores it's former state in reasonable speed. All relevant FN buttons send appropriate signals, when thinkpad_acpi is loaded as module or compiled into the kernel.

The machine runs with the builtin battery up to 3,0 hours.

Be sure that you have installed the latest BIOS (7LETC6WW (2.26 ) (05/11/2009)), available on Lenovo's support site, which has eliminated a lot of ACPI bugs of the older BIOS version here.

2. Installation

My ThinkPad T61 runs these days on Gentoo Linux amd64/13.0/desktop, because this Linux flavor avoids auto-configuration and some other here not wanted mumbo jumbo. It's running on a plain-vanilla Torvalds kernel 3.13.

3. General Hardware Data

This notebook is as solid as it's black case -- no fancy stuff, only boring, functional hardware.

3.1 CPU

The system comes with an Intel Core2Duo (Penryn) 2.4 GHz processor.

  power management:

The processor works without additional daemons nicely with the CPU-frequency governors of Linux-3.0.

Most times I use the ondemand or the conservative governor.

3.2 RAM

I bought the machine with 4096 MByte (2 x2048 MByte) RAM (SODIMM Synchronous 667 MHz, 64 bits) in the two available slots.

3.3 Hard disk

3.4 DVD-RAM

MATSHITA DVD-RAM UJ-862

Output from "lshw --class disk":

The hard disk is connected to the 82801HBM/HEM (ICH8M/ICH8M-E) controller in SATA AHCI mode, the DVD-RAM to the same controller in IDE mode.

3.5 FlashMedia Reader

The Ricoh R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter controller runs with driver "sdhci_pci.ko" without problems.

Output from "lshw --class system":

  *-system:0

3.6 Graphic chip

The system comes with an Intel X1300 video adapter, which uses shared system RAM.

Output from "lshw --class video":

This chip performs well with linux Kernel mode settings (KMS) on the linux console and with the X Window System display server. It displays a resolution from 1680x1050 pixels - or 210 columns and 65 lines on the text console resp. 444x277 millimeters with the X Window display server. It's no problem to switch from the text console to the X Window system display server and back.

To enable KMS, you need these options in your kernel configuration:

  CONFIG_DRM_I915=y
  CONFIG_DRM_I915_KMS=y
  CONFIG_FB=y
  CONFIG_FB_CFB_FILLRECT=y
  CONFIG_FB_CFB_COPYAREA=y
  CONFIG_FB_CFB_IMAGEBLIT=y

Deactivate all framebuffer drivers!

The free xf86-video-intel driver from xorg-x11handles DRM/DRI out of the box. Some hints form my xorg.conf:

  Section "Monitor"
        Identifier      "Generic DVI"
        VendorName      "Lenovo"
        ModelName       "Liquid Crystal Display"
        Option          "DPMS"
  EndSection

  Section "Monitor"
        Identifier      "Generic VGA"
        Option          "Enable" "false"
        Option          "Ignore" "true"
  EndSection

  Section "Monitor"
        Identifier      "Generic TMDS-1"
        Option          "Enable" "false"
        Option          "Ignore" "true"
  EndSection

  Section "Device"
        Identifier      "Generic Videocard"
        VendorName      "Intel"
        BoardName       "Integrated Graphics Device"
        Driver          "intel"
        Option          "LVDS" "Generic DVI"
        Option          "VGA" "Generic VGA"
        Option          "TMDS-1" "Generic DVI SDVO"
        Option          "AccelMethod" "UXA"
        Option          "Tiling" "false"
  EndSection

The xorg.conf doesn't needs Display SubSections anymore, as the resolution for the X Window System display server is with activated KMS configured by the linux kernel.

3.7 PCMCIA

CardBus bridge: Ricoh Co Ltd RL5c476 II (rev ba)

To get this device working, you'll need the modules pcmcia_core and yenta_socket.

3.8 Sound

Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

The sound comes quite clear, but with all common disadvantages of sound on laptops.

The module snd_hda.ko needs the following lines in /etc/modprobe.conf:

   alias char-major-116 snd
   alias char-major-14 soundcore

   alias snd-card-0 snd-hda-intel
   alias sound-slot-0 snd-card-0

   alias sound-service-0-0 snd-mixer-oss
   alias sound-service-0-1 snd-seq-oss
   alias sound-service-0-3 snd-pcm-oss
   alias sound-service-0-8 snd-seq-oss
   alias sound-service-0-12 snd-pcm-oss

   alias /dev/mixer snd-mixer-oss
   alias /dev/dsp snd-pcm-oss
   alias /dev/midi snd-seq-oss

   options snd cards_limit=1

BTW: The soundchip needs the analog codec, config option CONFIG_SND_HDA_CODEC_ANALOG=y.

3.9 Firewire

FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev 04)

The device seems to run with the module ohci1394.ko, but I haven't tested it yet -- no firewire devices all around.

3.10 Touchpad

The notebook's got a touchpad with 2 and a trackpoint with 3 buttons. The whole stuff is recognized as a ExplorerPS/2 mouse and works in X and on console with gpm started like this:

   # /usr/sbin/gpm -m /dev/input/mice -t exps2 -r 15 -Rraw

The X mouse listens to /dev/gpmdata. Here are some lines from my xorg.conf:

   Section "InputDevice"
        Identifier  "Touchpad"
        Driver      "mouse"
        Option      "Protocol" "MouseSystems"
        Option      "Device" "/dev/gpmdata"
        Option      "Buttons" "5"
        Option      "YAxisMapping" "4 5"
        Option      "XAxisMapping" "6 7"
        Option      "ZAxisMapping" "4 5"
   EndSection

The touchpad/trackpoint combo listens on the same PS/2 port as the buttons, so it doesn't need additional configuration.

3.11 Keyboard

The keyboard comes quite unspectacular as a generic model with 104 keys. The relevant FN-keys work surprisingly well, wenn the module thinkpad_acpi.ko is loaded with options thinkpad_acpi experimental=1. You may define your own key bindings with a properly configured acpid.

3.12 USB

USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller

The USB controller needs the kernel modules usbcore, uhci, ehci, kernel's storage subsystem usb-storage and SCSI hard disk support and supports USB 2.0.

3.13 Ethernet chip

Ethernet controller: Intel Corporation 82566MM Gigabit Network Connection (rev 03)

The on board chip uses the kernel module e1000e.ko and works like a charm.

3.14 WLAN chip

Network controller: Intel Corporation PRO/Wireless 4965 AGN Network Connection (rev 61)

The WLAN runs the kernel module iwlagn.ko, which depends on

as options.

The card needs Intel firmware, which is free available, but doesn't come with the kernel sources. You'll need to download the firmware package iwl4965-ucode on the Intel-Wireless download site.

3.15 Modem

The modem needs a propietary driver and is thus not tested here.

3.16 Fingerprint reader

STMicroelectronics Biometric Coprocessor

The fingerprint reader needs the kernel module uinput.ko and the software package thinkfinger. The device reads fingerprints in a reasonable way and works with an added line in /etc/pam.d/system-auth as alternative authentication method for users, which have deposited their fingerprints.

A nice HOWTO to get this device up and running is on ThinkWiki.

5. Survey PnP Devices

The Pnp devices are handled by ACPI.

Output from dmesg

  pnp: PnP ACPI init
  ACPI: bus type pnp registered
  pnp: PnP ACPI: found 10 devices

All hardware works well with a recent Linux kernel and my favorite distribution. The machine suspends to RAM and disk, from X or console -- and awakes from both suspend states again.
