ThinkPad R61i

This pages gives an overview of all ThinkPad R61i related topics.

Standard Features

I'm using Ubuntu 8.04 (Hardy Heron) on my Lenovo ThinkPad R61i. These are the hardware specific details of my installation. Some of my problems are not listed here as they vanished with a kernel upgrade. Actually I use the vanilla 2.6.24(-17-generic) kernel.

Hard disk issues

The disk does approx. 25 load cycles per minute. This could be too much. I guess this is related to a Linux/disk firmware bug.

Updateing the BIOS

I had to update the BIOS prior installing Linux as a stand alone operating system because only the win32 update utility worked, the bootable FreeDOS CD-image failed to boot: 

cdr101 not ready reading drive c.

ACPI issues

ACPI still remain an issue for Linux. The kernel code is made of spaghetti, full of legacy parts and crappy worksforme code.

Suspend, hibernate, resume

The current ACPI code is a reason for all sorts of problems around suspend, hibernate and resume, but luckily it works pretty stable for this model.

Hotkeys

All the hotkeys at the top work well. But the multimedia keys at the bottom (zoom,prev,play/pause,stop on space,left,down,right,up) do not work at all. They not even generate a kernel event, neither ACPI nor keyboard.

Hotswap drivebay

I don't have a second device, but the hotswap function obviously wouldn't work: ejecting the optical driver from the bay results in a kernel hang (no oops, no dump, just freeze). Not working at all, if no device is present at boot time, otherwise it should work.

Docking station

Couldn't test it, but the thinkpad_acpi documentation states that it should work, but only if a docking station is present at the boot time.

Fingerprint reader

Does not work. Lenovo replaced the TouchStrip fingerprint module (long used in ThinkPads by IBM) with one from UPEK. According to lsusb: 

Manufacturer	TouchStrip
Model		Fingerprint Sensor
Bus			usb
Type		Vendor Specific Class
Id			147e
Info2		2016

The fingerprint reader libthinkfinger won't work! UPEK claims to have an driver, but it failed to build for me. It uses proprietary code, and requires to use a scarce authentication model.

Trackpoint and touchpad

Works fine. You need to add 

Section "InputDevice"
       Identifier      "Synaptics Touchpad"
       Driver          "synaptics"
       Option          "SHMConfig"             "on"
EndSection

to xorg.conf to be able to configure it's characteristics in more detail. I prefer gsynaptics to disable tap clicking and enable a horizontal scroll.

Firewire

Not tested.

USB

Fast and flawless.

Gigabit LAN

Fast and flawless.

Bluetooth

Works well. To turn it on/off separately from the wifi (that can be done by Fn+F5), I use this script mapped to the blue 'ThinkVantage' button on the top: 

#!/bin/bash
cat /proc/acpi/ibm/bluetooth | awk '{ print $2 }' | while read line;
 do
   if [ $line == "enabled" ]; then
       echo disable > /proc/acpi/ibm/bluetooth
   else
       echo enable > /proc/acpi/ibm/bluetooth
   fi
   break
 done

Wifi

It is surprisingly stable and reliable. Although the LED for wirless activity does not work.

Video

Internal TFT

Good image quality, stable open source driver. Ubuntu has a patch for the X.org driver to get hardware overlay for XVideo working with compiz enabled. Additional tweaks are required to get compiz working, although some effects are utterly slow. Use this in xorg.conf: 

Section "Device"
       Identifier      "Configured Video Device"
       Driver          "intel"
       Option         "AccelMethod"           "EXA"
       Option         "ExaNoComposite"        "false"
       Option         "TexturedVideo"         "false"
       Option         "MigrationHeuristic"    "greedy"
EndSection

And add this to /etc/environment: 

LIBXCB_ALLOW_SLOPPY_LOCK=1
INTEL_BATCH="1"

External VGA

A little more problematic. Compiz gets too slow to remain usable on two monitors. This can't be because of the Intel chip, as rendering a simple cube with textures can't require hardcore 3D acceleration. Also GL screensavers result usually in a black monitor (no hang, just no console at all). I had to extend xorg.conf to get an appropriate virtual screen to fit both the internal and external displays in. 

Section "Screen"
       Identifier      "Default Screen"
       Monitor         "Configured Monitor"
       DefaultDepth    24
       SubSection "Display"
               Depth   24
               # no DRI above this
               Virtual 2048 2048
       EndSubSection
EndSection

xrandr works well for configuring the displays and managing the modes. The hotkey on the keyboard switches to clone mode. I prefer a more sophisticated control using this script.

S-VIDEO out

I don't know whether it is working or not, but it is not listed in xrandr.

Cardreader

Works flawless and out of the box.

Sound

Sound quality is good until PCM volume is below 75%. The internal microphone does not work at all. All the external microphones I used produced a horrible recording quality. Some voice recording programs failed to work or recorded silence. This is a big issue for me.

HDAPS

HDAPS should protect the hard disk in case of falling/dropping/hitting the laptop by parking the heads in case of unusual acceleration patterns. That's right, ThinkPads ship with an acceleration meter.

With the newest kernel the measuring works. hdaps-gl displays the orientation of the laptop in space. I submitted a kernel patch (for drivers/hwmon/hdaps.c) to lkml to reverse an axis: 

@@ -515,6 +515,7 @@ static struct dmi_system_id __initdata h
      HDAPS_DMI_MATCH_NORMAL("IBM", "ThinkPad R50"),
      HDAPS_DMI_MATCH_NORMAL("IBM", "ThinkPad R51"),
      HDAPS_DMI_MATCH_NORMAL("IBM", "ThinkPad R52"),
+       HDAPS_DMI_MATCH_INVERT("LENOVO", "ThinkPad R61i"),
      HDAPS_DMI_MATCH_INVERT("IBM", "ThinkPad T41p"),
      HDAPS_DMI_MATCH_NORMAL("IBM", "ThinkPad T41"),
      HDAPS_DMI_MATCH_INVERT("IBM", "ThinkPad T42p"),

Or you can simply add invert=1 to the module parameters of hdaps_ec.

Please note, that protection will not work! It seems that the kernel does not apply any protection, it just makes the measured valued available to userspace. More worse, there is no userspace or kernel tool available to do the parking (yet).

Battery

According to powertop there are 100-300 wakeups-from-idle per seconds. This seems very high. Power usage is between 15 and 22 watts. On batteries I enabled laptop-mode, dim the backlight and if not needed, I use the RF kill switch. 

# cat /proc/acpi/battery/BAT0/info

After half a year of heavy usage I have the above capacity and a runtime of 2,5-3 hours on batteries.

Modem

Who cares?

PCMCIA, CardBus

Not tested.

Kernel options

Do NOT add irqpoll to the kernel options as it will cause a severe nondeterministic behaviour.
