Sfortunatamente per il direct rendering bisogna installare i driver proprietari fglrx.

I driver della ATI sono generalmente più instabili di quelli del kernel e non sono liberi, per questo io preferisco usare quelli GPL.

Ad ogni modo tu puoi scaricarli dal sito ufficiale: http://www.ati.com

Regole Udev

Ho aggiunto il seguente `zzz.rules' in /etc/udev/rules.d/ :

KERNEL="sd[b-z]1" SYMLINK="storage"
KERNEL=="sd[b-z]2", SYMLINK="ipod"
KERNEL="sr0" SYMLINK="cdrom dvd cdrecorder"
KERNEL="nvram" MODE="0666"

Video

Se usi i driver proprietari della ati devi aggiungere la seguente stringa in /etc/fstab :

tmpfs            /dev/shm         tmpfs       defaults                 0   0

Serve ad attivare la memoria virtuale necessaria al direct rendering.

Comunque se non hai particolari esigenze puoi usare i driver nativi "radeon".

CD/DVD Burning

cdrecord and growisofs funzionano. Il mio config ( in /etc/cdrecord ) è semplicemente:

CDR_DEVICE=/dev/cdrom

Ethernet 1000 Mbit

La scheda di rete Ethernet Broadcom Tigon3 funziona perfettamente. Per caricare il modulo.. :

# /sbin/modprobe tg3

Puoi aggiungere questo comando in /etc/rc.d/rc.modules .

Wireless

Ecco qui il mio config del kernel:

#
# 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

Inoltre bisogna scaricare e installare correttamente il firmware ipw2200:

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

Se incontri difficoltà a caricare il firmware prova con questo:

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

Con udev >= 064 e questa opzione non dovrebbero esserci problemi.

Audio

Funziona bene, questo è il mio 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 sulla console

È possibile grazie al demone gpm:

# installpkg gpm-*-*-*.tgz
# chmod +x /etc/rc.d/rc.gpm
# /etc/rc.d/rc.gpm start

Per far funzionare gpm sia con il TrackPoint, sia con il TochPad che con un normale mouse usb editare il file /etc/rc.d/rc.gpm in modo che il dispositivo interessato sia /dev/input/mice

HotKeys

Grazie al progetto tpb possiamo usare i nostri "hotkeys" per compiere determinate azioni. (Comunque non sembra funzionare il tasto poweroff). Per il mio setup controlla la sezione Altre risorse

Configurazione del Kernel

Settaggi per il controller S-ATA

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

hack in libata.h per vedere i DVD (linux < 2.6.14)

Senza questo piccolo hack nei sorgenti del kernel non si possono riprodurre correttamente i DVD in quanto l'accesso al disco ottico risulta terribilmente lento.

Bisogna cambiare (nel file /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 */

in:

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

Per linux >=2.6.14 questo hack _è deprecato_! Basta infatti aggiungere alla boot cmdline del kernel: "libata.atapi_enabled=1"; See my lilo.conf. È importante, altrimenti il vostro lettore non verrà neanche rilevato!!
