Install Considerations for Gentoo 2006.0 (Minimal Install)

• General: if you don't require suspend, wireless and SMP all working at the same time Gentoo is a fine choice for the x60s. The dual cores speed up compilation time considerably, and most things will work - they just won't necessarily work with each other.

• You can make a bootable USB thumb by following the howtos at [1] or [2]. Both howtos work with livecd-i686-installer-*.iso and install-x86-minimal-*.iso.

• In make.conf set MAKEOPTS="-j3" to enable both cores (presuming you have the Intel Core Duo). As for CFLAGS, Intel Core Duo should be "-march=prescott" - see thread here for more details.

• Minimal install disk does not discover ethernet at typical net.eth0, but net.eth1. This may be because of the firewire port, but either way during install use net.eth1. Once you chroot into your environment, use net.eth0 as usual.

• Manual kernel installation requires that CONFIG_SCSI_SATA_AHCI be enabled (see here). If you do not enable this, you will receive a "Kernel Panic: VFS Cannot open root device." See that page for a working kernel config.

• In kernel, processor type should be Pentium 4.

• In kernel, SMP should be enabled with processor number of 2

• Main hard disk is at /dev/sda rather than /dev/hda. Only when booting from LiveUSB, the USB thumb is at /dev/sda and the hard disk at /dev/sdb/.

• Wireless for the Atheros chipset (0000:03:00.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01)) can be configured using the drivers available at madwifi.org. Network interface will then be located at ath0.

• Despite successfully configuring X.org on an x60s using the i810 driver, the combination of X.org 7.0 and the i810 driver refused to start X, giving an error of "No Screen Found." Workaround is configuring X to use the generic VESA driver. This does not offer, however, any acceleration and thus - I'm told - no xGL/AIGLX.

• When properly configured with DBus / HAL, USB automounting in GNOME worked perfectly.

• Bluetooth also works properly with the following kernel configuration:

CONFIG_BT=y
CONFIG_BT_L2CAP=y
CONFIG_BT_SCO=y
CONFIG_BT_RFCOMM=y
CONFIG_BT_RFCOMM_TTY=y
CONFIG_BT_BNEP=y
CONFIG_BT_BNEP_MC_FILTER=y
CONFIG_BT_BNEP_PROTO_FILTER=y
CONFIG_BT_HIDP=y

#
# Bluetooth device drivers
#
CONFIG_BT_HCIUSB=y
CONFIG_BT_HCIUSB_SCO=y

What Didn't Work

• Processor Frequency Scaling: Despite enabling processor frequency scaling in the kernel, both as module and in kernel, was unable to get processor frequency scaling to work correctly.

• Suspend to RAM / Suspend to Disk: Tried several tacks here. First was going the simple ACPI script route that worked successfully on the x40 - this did not work. Second was to attempt to achieve suspend and hibernate via the kernel, but as of 2.6.16-gentoo-r3, ACPI suspend to disk/RAM are unavailable once SMP is enabled. Last, was to install and configure suspend2 kernel - this did allow for simultaneous suspend and SMP, but also caused problems with the madwifi - modules could not be inserted into the kernel.

• Sound: snd_hda_intel should have worked, but did not.

Untested

• Did not bother with modem, SD card reader, IRDA or Firewire
• Both fingerprint reader and active protection system (HDAPS) have some support; did not try them

Other Comments

• Have seen multiple comments indicating high pitch whine when on battery power; this was not experienced.
• Battery life: insufficent experience, but did tend to be slightly more power hungry than Windows
