[edit] Graphics Card

[edit] nVidia NVS 110M Chipset

This card apears to be based on the Go7300 so it is not an gaming card. It uses TurboCache to make use of the system memory for the Graphics Memory. It does have 64MB of dedicated (onboard) video memory. But you can allocate up to 256 MB more to the graphics card.It should be plenty fast enough to do 3D Desktop features if you want though.

Driver support works great with the closed source nvidia-drivers. Make sure you get the latest driver version (currently 1.0.9629) if you wish to use the 3D desktop features. You may need to add ~arch to your package.keywords file to obtain this. The DRI project hasn't developed an Open Source driver that will use 3d features yet unfortunately. So you are left to using the closed source drivers if you need 3d support (recommended).

[edit] Intel GMA 950

See this HowTo.

[edit] Wireless Networking

[edit] Intel® PRO/Wireless 3945A/G (802.11a/g)

There are OpenSource drivers for this WLAN card.
These can be found here: http://ipw3945.sourceforge.net/
More info here: HARDWARE ipw3945 If you are not able to establist a connection but able to scan for wireless lans try to change the processor settings in your kernel configuration. It might help to switch down to i386 and find the best usable configuration via trial and error.

[edit] Dell Wireless 1490 (802.11a/g)

This seems to be an Broadcom WLAN card. More information: http://bcm43xx.berlios.de/

[edit] Dell Wireless 1390 (802.11g)

This seems to be an Broadcom WLAN card. More information: http://bcm43xx.berlios.de/

You can read the forumn article here on help with getting this to work. [1]

[edit] Dell Wireless 350 Bluetooth internal wireless card

I don't know much about it, but it seems to work with bluez and hci-usb modules. Both Gnome applets allow to exchange vcards, files through bluetooth. Motorola V3, V6 maxx and Sony Ericsson P990i are known to work flawlessly, while Samsung Z170 doesn't work at all.

[edit] Displays

[edit] Wide-aspect 14.1” WXGA (1280 x 800 resolution) 185 nits

This is an non-shining 14.1 WXGA screen.

I used mkxf86config to generate the HorizSync and Vertrefresh section of my xorg.conf. You can obtain it by running 

# emerge mkxf86config

Then use it to configure by running 

# mkxf86config

I then manually edited by xorg.conf file to change the resolutions to 1280x800.

You can feel free to copy them from mine posted here and paste them into yours.

[edit] Wide-aspect 14.1” WXGA+ (1440 x 900 resolution) 220 nits

This is also an non-shing 14.1 screen but then with an WXGA+ resolution. To set up this device add "1440x900" instead of the "1280x800" to the above. You also have to add a mode-line to the Monitor section: 

Section "Monitor"
        ...
        ModeLine "1440x900" 106.47 1440 1520 1672 1904 900 901 904 932 -hsync +vsync
        ...

[edit] UPEK fingerprint reader

It is possible to order the D620 with an internal fingerprint reader. The reader is internally connected via usb and lsusb names the device as "SGS Thomson Microelectronics Fingerprint Reader" (ID 0483:2016). The reader works quite well if you install the UPEK drivers using this tutorial: HARDWARE UPEK TouchChip TFM/ESS Fingerprint BSP The reader does not work if the internal usb-hub is switched to compatible mode (USB1.1). Just switch it to USB2.0 mode.

[edit] Internal USB-HUB

The internal usb-hub causes some problems if it runs in compatible mode (USB1.1). Just switch the device to USB2.0 using the system bios. The difference of the battery life time is between 5 and 10 minutes using the 9 cell battery.

[edit] Bluetooth

Standard bluez drivers work fine. Don't forget to turn on radio while in Windows. Same applies to RF kill switch - has to be on during boot.

[edit] Kernel Setup

This is a list of the nessesary devices you have to set up to be able to boot up the system. (kernel 2.6.20-suspend2-r6, different on <=2.6.18!) Harddisk and DVD support: 

Device Drivers -->
      ATA/ATAPI/MFM/RLL support -->
            < > ATA/ATAPI/MFM/RLL support
      SCSI device support -->
            <*> SCSI device support
            [*] legacy /proc/scsi support
            <*> SCSI disk support
            <*> SCSI CDROM support
      Serial ATA (prod) and Parallel ATA (experimental) drivers -->
            <*> ATA device support
            <*>   Intel PIIX/ICH SATA support

Please note that the ATA/ATAPI/MFM/RLL support has to be disabled to use DMA with the DVD or CDROM device!

[edit] Installation

[edit] Notes

I first tried the Gentoo 2006.1 LiveCD, but the Gentoo LiveCD didn't include support for the wireless card, the ipw3495. So I downloaded an Ubuntu LiveCD, unfortunaly the Ubuntu LiveCD didn't had SMP support. So I had only one core working. I did an stage1 install with the stage3 tarball's. After that I switched quickly to my new installed system with an SMP supported kernel. After the reboot I emerge'd everything I needed.

AIGLX works on my laptop very smooth :)

With the latest NVIDIA drivers (on the Quadro version of this laptop) you don't need to run AIGLX to get it to work with Beryl or Compiz. See the gentoo wiki on how to do this: [2]
