Mise en veille / Hibernation et optimisation de la Nvidia 8400GS du Dell XPS m1330 sous Ubuntu Hardy

Afin d’avoir un pc qui se met en veille et hiberne rapidement (”rapidement” pour l’hibernation est un gros mot je trouve, encore bien trop lent à mon goût) j’ai réglé mon fichier /etc/default/acpi-support comme ci-dessous, je ne garanti rien, mais pour info le mien est régler comme cela et ça fonctionne très bien.


sudo cp /etc/default/acpi-support /etc/default/acpi-support.bak && sudo gedit /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="uvcvideo"

# Add modules to this list to leave them in the kernel over suspend/resume
MODULES_WHITELIST=""

# Should we save and restore state using the VESA BIOS Extensions?
#SAVE_VBE_STATE=true
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=true

# 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="networking"

# 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=false

# Spindown time on battery
SPINDOWN_TIME=12

Vous devez également modifier dans /etc/X11/xorg.conf la partie concernant la carte graphique.
La partie concernant la carte nvidia 8400gs avec les drivers propriétaires fournis dans Ubuntu Hardy est ainsi :


sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak && sudo gedit /etc/X11/xorg.conf


Section "Device"
    Identifier     "nVidia Corporation G80 [GeForce 8400M GS]”
    Driver         “nvidia”
EndSection

Section “Screen”
    Identifier     “Default Screen”
    Device         “nVidia Corporation G80 [GeForce 8400M GS]”
    Monitor        “Écran générique”
    DefaultDepth    24
    Option         “RenderAccel” “true”
    Option         “AllowGLXWithComposite” “true”
    Option         “AddARGBVisuals” “True”
    Option         “AddARGBGLXVisuals” “True”
    Option         “OnDemandVBlankInterrupts” “True” # Optimisation
    Option         “Coolbits” “0″ # Passer à 1 pour permettre l’overclocking, à vos risque et péril !
    Option         “TripleBuffer” “true”
    Option         “NoLogo” “True” # Pas de logo au démarrage
    Option         “RandRRotation” # Rotation de l’écran avec la commande xrandr -o left par exemple
    Option         “NvAGP” “1″ # Résout problême d’hibernation
    SubSection     “Display”
        Depth       24
        Modes      “1280×1280″
    EndSubSection
EndSection

Section “Extensions”
    Option         “Composite” “Enable”
EndSection

Regarder les commentaires de celui-ci, je n’ai pas tout détaillé.

Avec ce xorg, compiz fonctionnel, pas de problème de mise en veille / hibernation, rotation de l’écran avec xrandr possible !

En espérant que ça vous soit utile !
