Hardware list
Hardware over PCI (lspci)

Hardware over USB (lsusb)

Components

Ethernet
The intended module "sky2" is broken for this device in kernels <2.6.27. Also see Sky2.

Currently there is no stable gentoo-sources-2.6.27. therefore we have to use unstable:

Processor
Nothing special needs to be done, see Core2Duo.

WLAN
The ath5k driver doesn't activate the antenna yet. The lscpi output seems to be wrong. Instead of a AR5006EG a AR5007EG is built-in. At the time of writing (03.10.2008), a special version of madwifi is needed. I've deactivated the mac80211 and ath5k modules and used the driver mentioned in http://madwifi.org/ticket/1192. Simply do the usual "make" and "make install" stuff and reboot (some people say it's necessary because of ath_hal). After that activate the radio with the following commands: sysctl -w dev.wifi0.ledpin=0 sysctl -w dev.wifi0.softled=1 I've testet "managed" and "master" mode, both work with the described setup. With the help of the patch from Bob Copeland (see kernel bug #12298), the ath5k module of the kernel activates the antenna. The modified patch is also available here. Deactivating the radio is still unknown.

For further configuration see the official guide:.

See also Atheros 5xxx.

Graphic card
Supported by the official nvidia driver. See also Nvidia.

Since version 177.70 our graphic card is supported. The latest official version is 177.80.

Further informations in section Xorg.

Touchpad
Works with the usual synaptics drivers (See Xorg section or Synaptics).

Sound
Works with the Intel HD Audio module.

If the internal mic works only for some apps (those who use oss f.e. skype): "Front mic" is the internal microphone, "mic" the plugable, set "Input Source" to "Front mic".

USB
Standard modules EHCI/UHCI work (needed for at least the camera and the cardreader), see USB.

S/ATA
Activate AHCI (if it's not per default) in the BIOS and use the AHCI module. Don't forget to activate the SCSI-Disk and SCSI-CdRom modules. The general guide for SATA.

ExpressCard
Untested. I have no such device, see ExpressCard.

Cardreader
Works with USB mass storage module. No special cardreader/MMC/SD/whatever module has to be activated.

Builtin camera
Works with the v4l uvc kernel module. Just activate the usual V4l stuff and the uvc kernel module. Tested with Mplayer and Skype. Cheese doesn't work, looks like a gstreamer problem.

HDMI
Untested. I have no such device.

VGA-Out
Untested, yet. Perhaps this guide is useful HOWTO_nVidia_TwinView.

Suspend-to-ram
Works with normal mechanism. See Aktivieren_von_Stromsparfunktionen (german).

Suspend-to-disc
Works with normal mechanism. See Aktivieren_von_Stromsparfunktionen (german).

Fn keys
Sleep and power button create ACPI-Events. Easy job for acpid.

Then edit /etc/acpid/defaults.sh

Other buttons send unknown key codes, Lower/Raise volume f.e., so we add the following lines to /usr/share/hal/fdi/information/10freedesktop/30-keymap-misc.fdi under the prefix "samsung":

and a Xmodmap file is necessary:

and execute the following command after login:

The problem with the other keys like brightness up/down is, that no key up event is generated. Further research need to be done.

Jürgen Graband posted a configuration script for Ubuntu in this thread. This script includes a kernel patch that seems to create the necessary key up event for this laptop. I didn't have the time to test it, yet, but it looks good and I copied it here.

Xorg
Flags in /etc/make.conf for Xorg:

The whole /etc/X11/xorg.conf with support for compiz:

To use the official nvidia driver don't forget to execute:

Console framebuffer
Works with uvesafb. Follow this guide:, but install the latest version of v86d, therefore execute:
