Pentru animalul de mai sus, va recomand un kernel cel putin 2.6.19 datorita unor buguri de "bad state" (a se vedea https://bugzilla.novell.com/show_bug.cgi?id=179702 ).
La acest model rezolvarea problemei a fost un kernel update,urmat de un upgrade de bios de pe pagina producatorului.


Distributia curenta pe acest model e Ubuntu 7.04 "Feisty Fawn". In timpul instalarii veti avea surpriza ca interfata grafica sa nu porneasca.
Workaround: instalati cu installerul in mod text sau din consola live-cd-ului sa dati: 

sudo apt-get update
sudo apt-get install xorg-driver-fglrx
sudo aticonfig --initial
/etc/init.d/gdm restart (gdm poate fi inlocuit de xdm/kdm).

Dupa instalare, activarea "Multiverse" si aducerea la zi a pachetelor, pentru rezolvarea diverselor probleme de suspend2disk/suspend2ram (vezi sudo pmi capabilities) am editat astfel /etc/default/acpi-support: 

# Comment the next line to disable ACPI suspend to RAM
ACPI_SLEEP=true
# Comment the next line to disable suspend to disk
ACPI_HIBERNATE=true
# Change the following to "standby" to use ACPI S1 sleep, rather than S3.
# This will save less power, but may work on more machines
ACPI_SLEEP_MODE=mem
# Add modules to this list to have them removed before suspend and reloaded
# on resume. An example would be MODULES="em8300 yenta_socket"
#
# Note that network cards and USB controllers will automatically be unloaded 
# unless they're listed in MODULES_WHITELIST
MODULES="ipw3945 sbp2 ohci1394 ieee1394"
# Add modules to this list to leave them in the kernel over suspend/resume
MODULES_WHITELIST="fglrx"
# Should we save and restore state using the VESA BIOS Extensions?
SAVE_VBE_STATE=false
# The file that we use to save the vbestate
VBESTATE=/var/lib/acpi-support/vbestate
# Should we attempt to warm-boot the video hardware on resume?
POST_VIDEO=false
# Save and restore video state?
# SAVE_VIDEO_PCI_STATE=true
# Should we switch the screen off with DPMS on suspend?
USE_DPMS=false
# Use Radeontool to switch the screen off? Seems to be needed on some machines
# RADEON_LIGHT=true
# Uncomment the next line to switch away from X and back again after resume.
# This is needed for some hardware, but should be unnecessary on most.
DOUBLE_CONSOLE_SWITCH=false
# Set the following to "platform" if you want to use ACPI to shut down
# your machine on hibernation
HIBERNATE_MODE=shutdown
# Comment this out to disable screen locking on resume
LOCK_SCREEN=true
# Uncomment this line to have DMA disabled before suspend and reenabled
# afterwards
# DISABLE_DMA=true
# Uncomment this line to attempt to reset the drive on resume. This seems
# to be needed for some Sonys
# RESET_DRIVE=true
# Add services to this list to stop them before suspend and restart them in 
# the resume process.
STOP_SERVICES="mysql "
# Restart Infra Red services on resume - off by default as it crashes some
# machines
RESTART_IRDA=false
# Switch to laptop-mode on battery power - off by default as it causes odd
# hangs on some machines
ENABLE_LAPTOP_MODE=true

Deoarece XGL din Feisty are unele probleme de functionare, in /etc/apt/preferences am adaugat urmatoarele pentru a prefera pachetele din repository-ul Beryl. 

Package: *
Pin: release o=lupine
Pin-Priority: 1000

Am adaugat in /etc/modules urmatoarele linii: 

cpufreq_conservative
cpufreq_ondemand
cpufreq_powersave
cpufreq_stats
cpufreq_userspace
acpi-cpufreq

Si am dezactivat powernowd din sysv-rc-conf (sudo apt-get install sysv-rc-conf) deoarece procesorul este unul Intel, iar power management e asigurat de laptop-mode-tools.

#
# Configuration for Laptop Mode Tools
# -----------------------------------
#
# There is a "system" to the configuration setting names:
#    CONTROL_something=0/1   Determines whether Laptop Mode Tools controls 
#                            something
#    LM_something=value      Value of "something" when laptop mode is active
#    NOLM_something=value    Value of "something" when laptop mode is NOT active
#    AC_something=value      Value of "something" when the computer is running
#                            on AC power
#    BATT_something=value    Value of "something when the computer is running on
#                            battery power
#
# There can be combinations of LM_/NOLM_ and AC_/BATT_ prefixes, but the
# available prefixes are different for each setting. The available ones are 
# documented in the manual page, laptop-mode.conf(8). If there is no LM_/NOLM_ 
# in a setting name, then the value is used independently of laptop mode state, 
# and similarly, if there is no AC_/BATT_, then the value is used independently
# of power state.
#
# Some options only work on ACPI systems. They are marked ACPI-ONLY.
#
# Note that this configuration file is a fragment of bash shell script: you
# can use all the features of the bash scripting language to achieve your
# desired configuration.

###############################################################################
# When to enable laptop mode
# --------------------------
#
# "Laptop mode" is the mode in which laptop mode tools makes the computer
# consume less power. This includes the kernel "laptop_mode" feature, which
# allows your hard drives to spin down, as well as various other settings which
# can be tweaked by laptop mode tools. You can enable or disable all of these
# settings using the CONTROL_... options further down in this config file.
###############################################################################
# Enable laptop mode when on battery power.
ENABLE_LAPTOP_MODE_ON_BATTERY=1
# Enable laptop mode when on AC power.
ENABLE_LAPTOP_MODE_ON_AC=1

# When to enable data loss sensitive features
# -------------------------------------------
#
# When data loss sensitive features are disabled, laptop mode tools acts as if
# laptop mode were disabled, for those features only.
#
# Data loss sensitive features include:
# - laptop_mode (i.e., delayed writes)
# - hard drive write cache
#
# All of the options that follow can be set to 0 in order to prevent laptop
# mode tools from using them to stop data loss sensitive features. Use this
# when you have a battery that reports the wrong information, that confuses
# laptop mode tools.
#
# Disabling data loss sensitive features is ACPI-ONLY.
###############################################################################
# Disable all data loss sensitive features when the battery level (in % of the
# battery capacity) reaches this value.

###############################################################################
# Controlled hard drives and partitions
# -------------------------------------
#
# For spinning down your hard drives, laptop mode will remount file systems and
# adjust hard drive spindown timeouts. These parameters specify which
# devices and partitions are affected by laptop mode.
###############################################################################
# The drives that laptop mode controls.
# Separate them by a space, e.g. HD="/dev/hda /dev/hdb". The default is a
# wildcard, which will get you all your IDE and SCSI/SATA drives.
HD="/dev/[hs]d[abcdefgh]"
# The partitions (or mount points) that laptop mode controls.
# Separate the values by spaces. Use "auto" to indicate all partitions on drives
# listed in HD. You can add things to "auto", e.g. "auto /dev/hdc3". You can
# also specify mount points, e.g. "/mnt/data".
PARTITIONS="auto /dev/mapper/*"
# If this is enabled, laptop mode tools will assume that SCSI drives are really
# SATA drives that only _look_ like SCSI drives, and will use hdparm to control
# them. Set this to 0 if you have /dev/sd devices and you want laptop mode
# tools to use the "sdparm" command to control them.

###############################################################################
# Syslog configuration control
# ----------------------------
# 
# Syslog daemons have a tendency to sync their log files when entries are
# written to them. This causes disks to spin up, which is not very nice when
# you're trying to save power. The syslog.conf can be tweaked to *not* sync
# a given file, by prepending the log file name with a dash, like this:
#
#       mail.*          -/var/log/mail/mail.log
#
# Using the following options, you can let laptop mode switch between
# different syslog configurations depending on whether you are working on
# battery or on AC power. To set this up, start by configuring these options
# for your syslog daemon, and then run lm-syslog-setup to create the various
# files. Then edit the laptop mode-specific syslog configuration files to
# remove the syncs only when laptop mode is active.
###############################################################################

# Laptop mode tools controls syslog.conf by replacing /etc/syslog.conf (or
# whatever you specify in SYSLOG_CONF) by a link to the files configured here.
