# Dell Latitude D600

The Dell Latitude D600 was released on 3/12/2003. Despite its age, it can prove to be quite a capable machine. With a couple exceptions, Linux support for the D600 is outstanding. Most of its components work automatically with Arch.

# Hardware

### Working

- Intel Pentium-M, with CPU frequency scaling
- ATI Mobility Radeon 9000 (radeon driver)
- Wireless card:
  - Intel 2200 Pro/Wireless Lan card (ipw2200 driver)
  - Broadcom BCM4306 rev2 Wireless card (b43legacy driver)
- Sigmatel STAC9750 AC'97 audio
- Fn key combos and audio buttons
- Alps DualPoint trackpad and pointing stick (synaptics driver)
- O2Media PCMCIA slot
- CD/RW, DVD+/-RW
- Broadcom BCM5702 gigabit ethernet (tg3 driver)
- Hardware monitoring (i8k kernel module, hddtemp)
- Sleep and resume (see Resuming from sleep section)

### Untested

- IRDA
- Conexant V.56 modem (probably works)

# Post-Installation

## Wireless

The D600 comes with either an Intel Pro Wireless 2200 or a Broadcom BCM4306 rev 2. Both are supported natively.

### Intel PRO Wireless 2200

As the driver is already included in the kernel the only thing that needs to be done is to install the firmware.

    # pacman -S ipw2200-fw

### Broadcom BCM4306 rev 2

The b43legacy driver is included in the kernel, so as with the Intel card, we just need to get the firmware for it.

You'll need to download the following two firmware files:

- http://mirror2.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
- http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o

And use b43-fwcutter to install the firmware files.

     $ tar xfvj broadcom-wl-4.150.10.5.tar.bz2
     # b43-fwcutter -w /lib/firmware wl_apsta-3.130.20.0.o
     # b43-fwcutter --unsupported -w /lib/firmware broadcom-wl-4.150.10.5/driver/wl_apsta_mimo.o

It would be bad if udev were to load the b43 driver, as it would conflict with b43legacy, so let's go ahead and blacklist it:

     # modprobe -r b43
     # echo "blacklist b43" >> /etc/modprobe.d/modprobe.conf

Finally, load the b43legacy driver:

     # modprobe b43legacy

## Trackpad

The trackpad and pointing stick are supported out-of-the-box, but to enable certain features, such as tap-to-click or edge scrolling, you'll need to write some Xorg configuration files.

Open your favorite text editor to the following file:

     /etc/X11/xorg.conf.d/10-evdev.conf

Comment out every line in the section referring to touchpads. It should look like this when you're done:

     #Section "InputClass"
     #        Identifier "evdev touchpad catchall"
     #        MatchIsTouchpad "on"
     #        MatchDevicePath "/dev/input/event*"
     #        Driver "evdev"
     #EndSection

Next, you'll want to create a configuration file for your trackpad. The following is a good starting point. You can add more Synaptics config options if you'd like.

    /etc/X11/xorg.conf.d/10-synaptics.conf

    Section "InputClass"
       Driver      "synaptics"
       Identifier  "touchpad catchall"
       MatchDevicePath      "/dev/input/event*"
       MatchIsTouchpad      "on"
       Option "VertEdgeScroll" "on"
       Option "HorizEdgeScroll" "on"
       Option "TapButton1"  "1"
    EndSection

Finally, restart X, and your trackpad should be fully functional!

## CPU Scaling

See CPU frequency scaling. All Pentium-M CPUs support Enhanced Intel SpeedStep, so you'll need the acpi-cpufreq driver.

Some BIOS revisions don't work properly with acpi-cpufreq, likely due to the driver being buggy or incorrect DSDT tables. If you're experiencing problems, flash your BIOS to A16 (the latest version.)

## Resuming from sleep

There is a serious problem with KMS in the radeon driver that prevents normal resume from sleep mode with this laptop. This will remain unfixed for the foreseeable future. (see: Redhat Bugzilla #531825) Setting `AGPMode=1` on the kernel boot line will workaround the issue. Another workaround, which works with varying degrees of success, is to set a primary password in the BIOS.

## Video Card

Use the open source xf86-video-ati radeon driver, available in the extra repository. ATI dropped support for the Radeon (RV250) Mobility FireGL 9000 after catalyst driver version 8.28.8.
