If however you see this:

Code: lspci
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E PCI Express Fast Ethernet controller (rev ff)

Then you need the driver from: as it's not in the stock kernel yet.

Intro: Pre-installation notes

Since the RTL8101E NIC is unsupported by the 2008.0 LiveCD/USB, and there is no optical drive, you have several options:

Once you are ready to install, follow the normal installation process as described in the Gentoo Installation Handbook.

Note: The machine boots the LiveCD almost perfectly, but I had a difficult time with framebuffer. So, it's probably best to use gentoo-nofb when the LiveCD boots.

CFlags for Intel Atom

The Aspire One comes with the new Intel Atom Diamondville CPU. This means that you need to set the correct CFLAGS in /etc/make.conf, or GCC won't compile stuff and you won't install Gentoo (I used a 32 bit i686 stage3 tarball). Note that GCC as of 4.2 supports the -march=native cflag, this will automatically set the correct flags for your CPU. For older versions of GCC, use -march=prescott

CFLAGS="-march=native -O2 -pipe" 

For more info, go check out this thread on the Gentoo Forums.

Warning: This CPU DOES NOT support 64-bit!

To install with everything you need, edit /etc/make.conf, and add VIDEO_CARDS and INPUT_DEVICES:

Code: Editing: /etc/make.conf
INPUT_DEVICES="keyboard synaptics mouse"

This will keep your settings, and supply support for the keyboard, touchpad, and external mice.

Now install xorg-x11:

Code: Install
emerge -av xorg-x11

Now go get a cup of coffee, or two, because this will take very long time to complete.

Configure X

After xorg-x11 is installed, configure it by running xorgcfg. Once the configuration program is loaded (we only need it to see if X window system works and for a raw config file), hit Ctr+Alt+Backspace to go back to the command line prompt. Copy the ~/ to /etc/X11/xorg.conf.

Now fire up your favourite text editor (ex.: nano) to add the following to /etc/X11/xorg.conf:

Warning: Pay special attention to the comments (text after #). They are necessary to set a proper font size. Otherwise the fonts in various programs will be quite large.

To configure the graphics card:

Code: Editing: /etc/X11/xorg.conf
Section "Device"
	Identifier  "Card0"
	Driver      "i810"
	VendorName  "Intel Corporation"
	BoardName   "Mobile 915GM/GMS/910GML Express Graphics Controller"
	BusID       "PCI:0:2:0"
	Option "NoDDC" # You need this to set correct DPI (HUGE font issue).
Section "Monitor"
	DisplaySize  195 113 # This whill set correct DPI (96 x 96) 
Section "Screen"
        SubSection "Display"
                 Viewport   0 0
	         Modes     "1024x600"
	         Depth     24

NOTE: - I believe that xorgcfg will select the driver "intel" for the graphics card. YMMV.

To configure the touch pad:

Code: Editing: /etc/X11/xorg.conf
Section "InputDevice"
	Identifier  "Mouse0"
	Driver      "synaptics" # This will enable scrolling, etc...
	Option	    "Protocol" "auto"
	Option	    "Device" "/dev/input/mouse0" # Touchpad.
	Option	    "ZAxisMapping" "4 5 6 7"
	Option      "CorePointer"

To configure an external USB mouse:

Code: Editing: /etc/X11/xorg.conf
Section "InputDevice"
        Identifier  "Mouse1"
	Driver      "mouse"
	Option      "Device" "/dev/input/mouse1"
	Option      "Protocol" "auto"
	Option      "ZAxisMapping" "4 5"
	Option      "Buttons" "5"
	Option      "SendCoreEvents" # '''DON'T FORGET THIS'''


See Atheros 5xxx and if you are using MadWifi, see the AR5006EG guide. Configure your card as described at Wireless/Configuration.

If you get the WLAN device up and working but can't list or associate with any access points, try flipping the wireless switch on the front-right of the laptop. It appears to have a physical switch which turns the wireless device off. Without the LEDs, it's difficult to tell if it's on or off.

I had to use the madwifi drivers from a recent snapshot [1] (not the trunk) otherwise the driver module would load, but fail to create any device. You can verify by using dmesg and checking for a problem reported by ath0 re the HAL and 0xe2. Also make sure you add 'madwifi' to your USE flags before compiling wpa_supplicant or it will not find the madwifi driver.


The was no support for Intel 82801G High Definition Audio in kernel-2.6.25. If, for some reason, emerge alsa-driver fails at compile time. You need to download latest alsa-drivers and install them manually (download latest alsa-driver from official ALSApage):

Code: Installing sound card
tar xvjf alsa-driver-1.0.17.tar.bz2
cd alsa-driver*
./configure --with-cards=hda-intel --with-sequencer=yes
make install

Now, go and emerge alsa-utils. After that just run alsaconf and voila: you have you sound card configured. Use alsamixer to adjust volume (the sound level is *very* low by default). And don't forget rc-update add alsasound boot!


Code: Install your webcam
ACCEPT_KEYWORDS="~x86" emerge linux-uvc
Code: Check if your webcam is detected
# modprobe uvcvideo
# dmesg | grep -i video
uvcvideo: Found UVC 1.00 device USB 2.0 Camera (0c45:62c0)

It seems everything is okay. However to be sure, we need to emerge luvcview and record some movies.

Code: Capturing video
# ACCEPT_KEYWORDS="~x86" emerge luvcview
# luvcview -f yuv
Warning: If luvcview fails for some reason, try using "-f yuw" instead of "-f yuv"

SDCard Reader

I had trouble getting the SD Reader to use a SD card. It took me a while to figure out the info from the quote below. (not needed with linux 2.6.27-rc7)

From the Debian Wiki: The card reader is hidden for some reason, so you have to add "setpci -d 197b:2381 AE=47" to your rc.local script to unhide it on boot. A script to poll the card reader for card and power events (AC unplugged etc) is included on the recovery DVD shipped with the machine within the "hdc1._.tar.bz2" archive as /usr/sbin/

Additionally, the SD Card must be inserted before the laptop boots to be properly detected.

You should see this if the machine has sucessfully detected a card in either slot.

Code: dmesg | grep mmc
mmc0: new SD card at address 1234
mmcblk0: mmc0:1234 SD01G 995328KiB
mmcblk0: p1

It shows that it found a 1GB card with a single partition, p1.

You can use the following device node to mount the card. /dev/mmcblk0 is the node of the whole card, like /dev/hda, and /dev/mmcblk0p1 is a partition on the card.

Code: Mount first partition on SD card
mount /dev/mmcblk0p1 /mnt/sd
