Unfortunately for direct rendering, you need fglrx proprietary driver installed.

ATI driver is little buggy and not free (as in speech), so i prefer GPLed one.

Btw you can download fglrx driver from ati.com

Udev rules

I have just added this `my.rules' in /etc/udev/rules.d/ :

KERNEL="sd[b-z]1" SYMLINK="storage"
KERNEL="sr0" SYMLINK="cdrom dvd cdrecorder"
KERNEL="nvram" MODE="0666"

And commented in /etc/udev/scripts/make_extra_nodes.sh CDs and Floppies nodes.

Video

ONLY If you use ATI Proprietary driver you must append follow string to /etc/fstab :

tmpfs            /dev/shm         tmpfs       defaults                 0   0

It's necessary to use direct rendering.

However if you have not particulars demand you can use kernel's radeon native driver.

CD/DVD Burning

cdrecord and growisofs work fine. My cdrecord config ( /etc/cdrecord ) is:

CDR_DEVICE=/dev/cdrom

Ethernet 1000 Mbit

Ethernet controller Broadcom Tigon3 works perfectly with :

# /sbin/modprobe tg3

You can add it to /etc/rc.d/rc.modules (if you use Slackware Linux) or equivalent for your distro.

Wireless

Here my kernel config:

#
# Network testing
#
# CONFIG_NET_PKTGEN is not set
# CONFIG_HAMRADIO is not set
# CONFIG_IRDA is not set
# CONFIG_BT is not set
CONFIG_IEEE80211=y
# CONFIG_IEEE80211_DEBUG is not set
CONFIG_IEEE80211_CRYPT_WEP=m
# CONFIG_IEEE80211_CRYPT_CCMP is not set
# CONFIG_IEEE80211_CRYPT_TKIP is not set
CONFIG_WIRELESS_EXT=y

[...]

#
# Wireless LAN (non-hamradio)
#
CONFIG_NET_RADIO=y
# CONFIG_NET_WIRELESS_RTNETLINK is not set

[...]

#
# Wireless 802.11b ISA/PCI cards support
#
# CONFIG_IPW2100 is not set
CONFIG_IPW2200=m
CONFIG_IPW2200_MONITOR=y
# CONFIG_IPW2200_DEBUG is not set
# CONFIG_AIRO is not set
# CONFIG_HERMES is not set
# CONFIG_ATMEL is not set

Besides you must download, install and load correctly ipw2200 firmware:

tar xvzf ipw2200-fw-3.0.tgz
cp ipw2200-fw-3.0/* /lib/firmware

If you have problem to load firmware take a look at this trick:

# sysctl -w kernel.hotplug=/sbin/udevsend

With udev >= 064 and this option I have no trouble.

Sound

Works fine, here my config:

#
# Sound
#
CONFIG_SOUND=y

#
# Advanced Linux Sound Architecture
#
CONFIG_SND=y
CONFIG_SND_TIMER=y
CONFIG_SND_PCM=y
# CONFIG_SND_SEQUENCER is not set
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=y
CONFIG_SND_PCM_OSS=y
# CONFIG_SND_VERBOSE_PRINTK is not set
# CONFIG_SND_DEBUG is not set

#
# PCI devices
#
CONFIG_SND_AC97_CODEC=y
...
CONFIG_SND_INTEL8X0=y
#
# Open Sound System
#
# CONFIG_SOUND_PRIME is not set

Mouse on console

It's possible thanks to gpm daemon:

# /usr/sbin/gpm -m /dev/input/mice -t ps2

gpm runs smoothly with TrackPoint, TouchPad and USB Mouse.

HotKeys

Thanks to tpb project we can use our Thinkpad's hotkeys. (However I can't use poweroff.) For my configs see in the Other resources section.

Kernel configuration

Settings for S-ATA Controller

#
# ATA/ATAPI/MFM/RLL support
#
# CONFIG_IDE is not set

#
# SCSI device support
#
CONFIG_SCSI=y
CONFIG_SCSI_PROC_FS=y

#
# SCSI support type (disk, tape, CD-ROM)
#
CONFIG_BLK_DEV_SD=y mmx fxsr sse sse2 ss tm pbe nx est tm2
# CONFIG_CHR_DEV_ST is not set
# CONFIG_CHR_DEV_OSST is not set
CONFIG_BLK_DEV_SR=y
# CONFIG_BLK_DEV_SR_VENDOR is not set
# CONFIG_CHR_DEV_SG is not set
# CONFIG_CHR_DEV_SCH is not set

# SCSI low-level drivers
#
...
CONFIG_SCSI_SATA=y
...
CONFIG_SCSI_ATA_PIIX=y
...
CONFIG_SCSI_QLA2XXX=y
...

libata.h hack to view DVDs (linux < 2.6.14)

Without this little hack in the kernel's source you can't play correctly your DVDs-movie.

You must change (from /usr/src/linux/include/linux/libata.h) :

#undef ATA_ENABLE_ATAPI /* define to enable ATAPI support */
#undef ATA_ENABLE_PATA /* define to enable PATA support in some
* low-level drivers */

to:

#define ATA_ENABLE_ATAPI /* define to enable ATAPI support */
#define ATA_ENABLE_PATA /* define to enable PATA support in some
* low-level drivers */ 

For linux >= 2.6.14 this hack _is deprecated_! Is enough append to boot cmdline: "libata.atapi_enabled=1"; See my lilo.conf.
