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:
