Toshiba_Satellite_U400-138

Introduction

This is a reference/guide for installing Gentoo on Toshiba Satellite U400-138 laptop. This laptop was releasede in the first half of Summer 2008, therefore new drivers and new information will probably be available. Eventually this reference may become outdated so please edit this if you find better ways of getting things done.

For all these experiments, Linux 2.6.27-rc8 was used.

Ethernet

Marvell Yukon 88E8040T works with the Sky2 Module. In kernels earlier than 2.6.26 this module had to be patched. Since .26 it works out of the box.

Wireless

The new Intel wireless card works as well with the new iwlagn driver, although it seems to be much more in the userspace than before. With kernels since .26 it works out of the box. Firmware from Intel is required as usual. This is not a major problem, as it is in portage.

# emerge net-wireless/iwl5000-ucode
# modprobe iwlagn

# lsmod

Module      Size      Used by
iwlagn    148100      0
iwcore    119364      1 iwlagn

Webcam

The Chicony webcam is connected via internal USB. The required drivers are listed below. It works flawlessly. The driver creates a /dev/video0 device, default for Skype and Mplayer. Works in both. The internal microphone is not yet tested though. A couple of drivers is required. The main one is loaded, it then autoloads the dependencies. (so make sure to compile those as well)

# modprobe uvcvideo

# lsmod

Module            Size      Used by
uvcvideo         46216      0 
compat_ioctl32    1536      1 uvcvideo
videodev         30464      1 uvcvideo
v4l1_compat      12548      2 uvcvideo, videodev

Bluetooth

This is a tricky one. After you've enabled all the bluetooth support in the world you can get in the kernel, you find yourself screwed. The bluetooth device is disabled by default in BIOS. The toshiba or toshiba_acpi drivers will not help, because the laptop has a Phoenix BIOS.

Fortunately, the omnibook drivers are in portage and they seem to work, at least for Bluetooth. Make sure you emerge the latest omnibook version (masked by ~x86 keyword)

# echo 'app-laptop/omnibook ~x86' >> /etc/portage/package.keywords

# emerge -va app-laptop/omnibook

# modprobe omnibook ectype=14

Now you should be able to turn the Bluetooth device on and off along with the wireless radio using the RFkill switch on the front side of the laptop. IT should also appear in the lsusb listing.

Graphics

In progress... coming soon.

Sound

In progress... coming soon.

Other, Toshiba specific features

Volume control wheel, special multimedia keys, LEDs - to be resolved.
