Linux on an IBM / Lenovo T61 8895WFJ


I'm using Gentoo Linux, but that does not matter, this document is not distribution specific.

As this device is pretty new, it's advisable to get an up-to-date kernel, I assume you're using 2.6.26, xorg-server 1.5, xf86-video-i810 2.4.2 and xf86-input-synaptics 0.15.2.


Works out of the box
Works with extra effort
Works partly
Does not work at all
Not tested

BIOS UpdateBIOS update is available as an ISO-image, burn it on CD and boot it, no problem with Linux.
BIOS Mods/HacksThere's a modified version of the T61 BIOS. Main feature is improved SATA-II if you use modern SSD drives. Use at your own Risk.
CPU CFLAGS Starting with gcc 4.3, gcc knows the option -march=core2 to optimizes code for the Intel Core 2 Duo.
(for older gcc versions, -march=nocona is the best option)
Graphics For proper graphics acceleration, one needs GEM. You'll need at least libdrm 2.4.1, mesa 7.3, xf86-video-intel-2.5.0 and a kernel above 2.6.28.
Screen brightness The Thinkpad video support (CONFIG_THINKPAD_ACPI_VIDEO) in current kernels no longer works. Instead, you'll have to use normal ACPI video support (CONFIG_VIDEO_OUPTUT_CONTROL and CONFIG_VIDEO_ACPI enabled).
CD/DVD drive Not just Linux related, but there's an inofficial firmware update that will remove some restrictions from the drive:
Liggy's and Dee's modified Optiarc AD7910A firmwares
Disclaimer: This may destroy your hardware and I haven't tested this.
Repair Not exactly a Linux issue, but Lenovo provides a Hardware Maintenance Manual.
