Debian Unstable on a Lenovo Thinkpad X61

by Kai Hendry (any tips please get in touch)

Overall I think the X series is the best laptop to run Debian on, despite my following complaints =)

X61 Thinkpad

Some of my configuration files

    [[!inline pages="hardware/x61/*" archive="yes" ss="no" atom="no" timeformat="%F"]]

Install

via USB

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=401832

Unfortunately the new X61 with the Debian installer from a USB stick failed to work with the Boot error message. I did test the d-i USB stick with a friend's Compaq. On the Compaq the USB installer works, however further testing showed the USB stick does not work with my older X40 Thinkpad. So I suspect an odd bug with Debian install USB images with (my) Thinkpads. USB sticks created with Debian Live are fine with my Thinkpads.

So unfortunately I had to waste a few hours of my life installing the OEM pre-install of Microsoft Vista. Vista ran painfully slowly on 1G of RAM and there are tons of retarded 3rd party applications that I assume Lenovo put on there. However once Vista booted, the win32 debian installer that is Goodbye Microsoft works well. However you must run cmd as Administrator and alter the boot timeout, before trying to reboot into the Debian Installer. Otherwise you will not be able to choose the Debian installer and you'll reboot into Vista again!

Initial Debian install

I installed etch and then immediately switched my sources.list to unstable. I started the install in the USA and finished in the UK, hence I needed the sudo dpkg-reconfigure tzdata command to setup the timezone.

I think I did try LVM with Debian Etch installer, but it did not work. :/

via PXE (finally!)

Painfully I re-installed my X61 to 686 (from amd64) with LVM using the very latest Debian installer. You might find this network TFTP boot guide helpful. :)

:r !cat /proc/cpuinfo

top does not show them as two seperate processors. So I am wondering how the processing actually works. When I compile WebKit the cc1plus process only seems to take 30-odd percent of the CPU on top. I'm very confused.

Speed stepping does seem to work. It seems to drop down to 800/2001 mhz in normal use.

:r !free -m

Since the X61 I bought from Newegg only had 1G of memory, I wanted more. Armed with the memory information of the X61 I went to Frys in Palo Alto (thanks Paul from ACOA for the ride!) for the upgrade. I bought a single 2G RAM module and removed the two 512mb modules. Frys staff were kind enough to borrow me a small philips screw driver for me to perform the upgrade then and there.

             total       used       free     shared    buffers     cached
Mem:          2006       1611        395          0         77       1170

Swap:         2827          0       2827

I didn't try, but I suspect another 2G module could bring the machine to 4G. I should also try putting in one of the 512mb modules I took out.

I wish the thinkpad was sold with a RAM module socket for upgrades. I guess Lenovo save money by using 512mb modules for fulfilling orders.

Problems and solutions

"Low Battery Alarm" fails

Beep when you're low

Though:

x61:~% cat /proc/acpi/battery/BAT0/alarm
alarm:                   3604 mWh

And the BIOS is correctly set. There is no audible alarm like that of my Thinkpad X40 that the battery is running low. I don't notice the visual battery indicator in the status bar. :(

Microphone capture doesn't work (solved)

You need to setup the capture devices with alsamixer -V capture. See not notes on:

`alsamixer -V capture`

Btw to configure sound output with the correct kernel modules, that's easy with:

x61:~% sudo alsaconf

After a day sound playback becomes unbearably choppy

Using 2.6.26-1-686 and ALSA 1.0.16.

This is really irritating.

SIM card slot mystery

Sim slot on a Thinkpad

Why the mystery? I want to know how to access my SIM card! Any ideas? Right now I am quite happy accessing Internet via bluetooth mind ... I don't want one SIM card for my Lenovo and another for my phone. That's going to probably be expensive...

X61 backlight does not work (solved)

Use xbacklight as of version 7.3 of X.org.

/usr/bin/xbacklight -set 100%

I'm a little confused now how this relates to brightness. :)

Think keys don't work

Keys like the volume buttons, brightness and suspend Fn keys don't work. There does seem to be some ongoing work on the ibm-acpi-devel -- ibm-acpi Linux driver development.

X doesn't work with Intel (solved)

Intel Graphics Media Accelerator X3100

Used VESA driver instead initially. Something to do with agpart missing.

Later I tried the reconfiguring X again sudo dpkg-reconfigure xserver-xorg and the Intel driver decided to work.

Dec 21 00:54:32 x61 kernel: [drm] Initialized drm 1.1.0 20060810
Dec 21 00:54:32 x61 kernel: [drm] Initialized i915 1.6.0 20060119 on minor 0

glxgears seems to run slow, but returns output like:

883 frames in 5.2 seconds = 169.373 FPS
840 frames in 5.2 seconds = 161.166 FPS
840 frames in 5.2 seconds = 160.245 FPS

Bit odd?

Wireless does not work (semi-solved)

I have this 03:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG Network Connection [8086:4227] (rev 02) device. Annoyingly there are several ways to drive this device. I've gone for the most recent kernel and the firmware-iwlwifi. firmware-ipw3945 seems to be more popular, though 'iwlwifi' seems to work for me:

x61:~% dmesg | grep 3945
iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 0.1.15ks
iwl3945: Copyright(c) 2003-2007 Intel Corporation
iwl3945: Detected Intel PRO/Wireless 3945ABG Network Connection
iwl3945: Tunable channels: 11 802.11bg, 13 802.11a channels
wmaster0: Selected rate control algorithm 'iwl-3945-rs'

ifconfig -a might show the wlan0 interface name screwed up (esp. if you upgraded from Debian etch to unstable). I used the fix in the Debian Wiki's iwlwifi page with the help of #debian-boot people.

Currently it can join a WPA secured network fine, but it can't join a very ordinary WEP secured network, with the error:

mismatch in privacy configuration and mixed-cell disabled - abort association

The X61 wireless interface sadly seems rather inflexible like my X40. You have to reboot the machine to join a new network once you've associated with a network beforehand. In my experience this a typical problem with linux & wireless devices. I assume wireless devices are deliberately cripled by hardware vendors and their firmware to prevent 'hackers' from scanning wireless networks and breaking any radio laws.

When things go well you'll see:

The iwlwifi seems generally quite unstable. :( I've heard of people removing the intel wireless and replacing it with a better atheros based mini-pci device. Or perhaps resorting to the earlier driver ... :(

Sometimes it completely fails and requires a reboot

Fan is always on (solved)

The fact of the matter is that the Thinkpad X61 runs hot (bad Lenovo design), so you'll probably need the fan even whilst the machine is idle or off mains. :(

Controlling fan noise

From 2.6.23+ the kernel module 'thinkpad_acpi' supersedes 'ibm_acpi'.

If you get "bash: echo: write error: Invalid argument" error message you are missing "experimental=1 fan_control=1" arguments on the thinkpad_acpi modprobe. To properly configure this on a Debian system edit /etc/modprobe.d/thinkpad_acpi.modprobe.

x61:~% grep fan /etc/modprobe.d/thinkpad_acpi.modprobe
options thinkpad_acpi hotkey=enable,0xffffbf experimental=1 fan_control=1

Since the Thinkpad embedded fan controller is a bit dumb ass, you unfortunately need to run your own fan controller script.

To monitor temperature I use yacpi and have a look how I use yacpi with my window manager (screenshot). Also I use root-tail to see what tp-fancontrol is doing by logging messages to my background.

Bluetooth for dialup Internet (life changing)

(Bluetooth) Internet at Heathrow

Configured with the help of this bluetooth dialup Internet guide.

Bluetooth is fantastic as it allows me to use dial up networking (DUN) of my Nokia E65 to connect to the Internet with 3G. :)

Suspend

Radically reduce boot times by issuing sudo s2ram -f -a 3 instead of sudo halt. Works great. Need to lock the screen with something like slock beforehand mind. Would be great to study if power is consumed.

Btw in suspend you'll see the crescent moon symbol light.

It seems to work 2 out of 3 times on my current 2.6.26 configuration... :/

SD card reader not working (solved)

You need to load the mmc_block and sdhci modules manually in /etc/modules for some reason and also checkout my fstab to see how I mount typically my camera's SD card on /mnt/sd.

x61:~% mount | grep mmc
/dev/mmcblk0p1 on /mnt/sd type vfat (rw,noexec,nosuid,nodev,user=hendry)
x61:~% df -h | grep mmc
/dev/mmcblk0p1        3.8G   32K  3.8G   1% /mnt/sd

Good news! The X61 supports my new 4G SDHC card:

Apr  9 14:19:49 x61 kernel: mmc0: new SDHC card at address e624

And the SDHC card works in my "Canon IXUS 950 IS" camera.

Unplugged power consumption ~16W

According to powertop long term: 17.0W,/4.2h on the biggest 8 cell battery. My X40 by comparison could run as low as 10W for extended periods, though its 8 cell battery is old.

Silly wireless switch

The wireless driver iwl3945 seems to cause wakeups, though I am not even using it. Very dissapointing. The wifi switch is not very useful as it also switches off bluetooth. When I am out and about I like to switch off wifi and just use bluetooth to access the Internet on trains for example.

Scary IRQ messages (solved)

Bios update .... I'm scared

I get this message on 2.6.23 or 2.6.24 kernels with Bios: 1.06 (7NET25WW)

Disabling IRQ #21

This is a Lenovo problem that is fixed in their BIOS update as the changelog:

(Fix) Unexpected interrupts from the USB controller may occur. (BIOS)

I created a bootable USB stick using approach 4 from Thinkwiki and Lenovo's ISO update for the X61.

I tried to dd my USB stick to an image file to share this upgrade resource. However dd creates an image 2G large which bzip2 is unable to radically downsize for sharing. :(

Screen brightness

High brightness

In the BIOS I've ramped up the brightness. I think this Lenovo option is a little silly. I wish they just fitted a decent LCD panel. Current thinkpad screens are dim and have poor viewing angles compared to competitors. :(

Other concerns

Definitely areas of improvement are:

  • The top side of the lid hole see note - reader informs me this is where bluetooth is installed
  • the ThinkVantage panel weakness - very tacky
  • Why the wireless switch and what about Fn+F5?
  • needless cardbus/pcmcia slot - who uses this?
  • remove the firewall port and add one more USB port (3 is an improvement from 2 of the X40)
  • Remove the Windows keys (waste of space) or perhaps remove the Fn key?
  • The mouse buttons are sadly not as solid as those on the X40 - the Thinkpad thankfully is the only laptop I can think of with a dedicated middle/third mouse button, which is very nice for X users.
  • stories of the keyboard scratching the screen (doesn't affect my model)
  • fingerprint reader. wtf actually uses this? remove it or make it more integrated with hardware (see not about hard drive encryption below)
  • the XGA screen is just terrible compared to almost any other laptop out there. Too dim and surely you could give us a SXGA option? Please?
  • The new power standard. What a feck up! Many companies such as Google have setup their conference rooms with the old Thinkpad PSU style. Since Lenovo has changed it, it has really pissed off people including myself. Lenovo's excuse is that Intels require more power. This is a laptop computer, laptops should be using LESS POWER, not more!

Lenovo's poor international warranty & customer service

Since this Thinkpad X61 was bought in the states, it seems to only have a warranty for the USA. :(

This is poor because when I bought my previous Thinkpad X40 in Korea, I had world wide onsite warranty included. No extra charge. I used it whilst travelling and generally had some excellent IBM support people service my X41's laptop hard drive which crashed a couple of times ...

Also when you buy an Apple Macbook in the states, you'll have warranty in the UK (ok, this can depend).

Worldwide warranty is professional and what IBM thinkpad owners expect.

Ricardo also writes in to say:

I have only the portuguese warranty, no international one, and, to my
disappointment, here you can't buy the extended care warranty, the one that
protects from spills and drops... Lenovo is really a bit worse than IBM.

Innovate ffs Lenovo

Lenovo's innovation is very poor. A good feature that some good engineers could figure out is hardware encryption. So I don't have to mess about applying encryption as software for my hard drive partitions and suffer the overhead for doing so.

UPDATE: Full Disk Encryption is the answer to my prayers. Thank you Lenovo. Now just make your computers cheaper now please. An EEEPC 1000 Atom based machine isn't far off an X61 and 1/5 of the price here in the UK!
