Installation instructions for the ThinkPad X61s
The following features work out-of-the-box with Ubuntu 7.10:
- 3D rendering
- Hot keys: sound, brightness, keyboard light, monitor, suspend
- ACPI, battery monitor
- Sound card
The following features don't work out-of-the-box:
- suspend fails: seemingly due to the ipw3945 ethernet driver
- Trackpoint's mouse wheel emulation
Still not solved?
- Bluetooth: Under Gnome I can not enable and disable bluetooth from linux. Have to run the windows program which controls bluetooth and enable it. After reboot it will remain enabled (the led indicates it). However there is a hardware switch which turns off all radio communications (including Bluetooth, Wireless Lan, and WAN (3G)), and there is also the possibility to disable each one of them separately from BIOS.
Bluetooth can be enabled by $echo enable > /proc/acpi/ibm/bluetoothBolle 20:58, 28 December 2007 (CET)
- 3G: Not tested.
- Fingerprint reader: Not tried to install it. Suggestions about installation and use?

Kubuntu 7.10 (Gutsy Gibbon)
Used Kernel: 2.6.22-14-generic
There are some subtle differences to the Ubuntu installation mentioned above, so I make a separate section. I also made a non-standard installation by using LVM over dm-crypt to get an entirely encrypted disk, except the /boot partition.
The following features work out of the box:
- Power Management
- Sound (without hotkey support!)
The following features did not work:
Entering and waking up from hibernation took a bit too long, giving me a bunch of too-fast-to-read USB errors on the console screen before shutting down. Notebook also stays blank screen mode after wakeup, until pressing the "enter" key to provoke a wrong password entry in the screensaver dialogue.
- suspend to RAM
Waking up from suspend to RAM does not work, the backlight of the screen is not reactivated. Need to reboot to reactivate.
The hotkeys for adjusting the brightness, mute, volume up/down anddo not work. Using "acpi_listen" shows, that some of the keys are recognized, so Kubuntu does not interpret them correctly. Some keys are not recognized at all. Here is an overview:
|(brightness up)||ibm/hotkey HKEY 00000080 00001010, video LCD0 00000086 00000000|
|(brightness down)||ibm/hotkey HKEY 00000080 00001011, video LCD0 00000087 00000000|
|Mute||first time: METHOD UCMS 00000000 00000000, after that: nothing|
|Volume down||first time: METHOD UCMS 00000000 00000000, after that: nothing|
|Volume up||first time: METHOD UCMS 00000000 00000000, after that: nothing|
However, adjusting brightness with KDE Powermanager does work, as well as adjusting volume using Kmix. You can also "echo" values into /proc/acpi/ibm/...
- WWAN (UMTS)
I have not tested it yet, I am still looking for a good UMTS flatrate. The device does show properly identified during bootup (use dmseg if you did not pay attention :) and should be usable via kppp.
Debian Testing (Lenny)
with kernel 2.6.22-2
There are some observations on: http://www.linux-on-laptops.com/hosted/lenovo-ibm-x61s.html
I would remark that I do control brightness of the screen from command line (not with the keys):
aptitude install xbacklight; xbacklight --help
There is a problem with reproducing video while using Compiz: https://bugs.launchpad.net/fedora/+bug/111257
It is recommended the insertion of the module:
Debian Stable (Edgy Etch)
I have followed the following steps to do the installation:
1) Install Edgy Etch in its normal way.
Several things did not work: acpi, sound, clock restoration, wireless, graphics driver set to vesa.
The ethernet card works perfectly and the vesa driver works fine.
2) Download a new kernel (in my case 184.108.40.206).
3) Compile and install the kernel the "Debian way" (http://www.debian.org/releases/stable/i386/ch08s06.html.en).
I had to enable several deprecated ACPI items because Debian Stable access some resources the old way.
4) Include backports sources into /etc/apt/sources.list.
deb http://www.backports.org/debian etch-backports main contrib non-free
5) Install package sysvinit from backports.
# apt-get -t etch-backports install sysvinit
Necessary because the new kernel has reimplemented the access to SATA disks, and Edgy Etch default shutdown does not park the disk heads correctly. (A message about SPIN DOWN the disk was shown).
6) Edit /etc/default/rcS and set HWCLOCKPARS="--directisa".
- Sound works: Since each time I wake up the computer the volume is reseting.
- Ethernet works.
- Wireless does not work yet: I think I have to enable some thing into the kernel but did not find what yet.
- ACPI works partially: temperature, fan and battery indications works perfectly throw acpitool and icon indication respectively.
- ThinkLight works, but the other Fn buttons does not: brightness, battery, sleep, etc.
- Suspend and Hibernation does not work. Hibernation seems to work, but after saving the session and poweroff, the system wake up automaticallly.
- Clock restauraton works.
- I still work with driver vesa. It works fine, and makes what I want when I hire an extenal monitor (poweroff the laptop monitor and use the external one), but I have some problems when I logout from X and go to text terminal ( ) without external monitor. The screen turns blank.
- I do not know if TurboMemory is recognized. I would like to configure it as swap partition.
I will try to solve this problems in near future.
