Laptop HP Nw 8440
Salut,
In randurile de mai jos va voi povesti despre experientele mele sexuale cu un laptop HP Nw 8440 si linux.
In primul rand configuratia hardware:

florin@samflorin-laptop:~$ grep -i model /proc/cpuinfo model : 15 model name : Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz model : 15 model name : Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz
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?

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.

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. ############################################################################### ############################################################################### # Configuration debugging # ----------------------- ############################################################################### # Set this to 1 if you want to see a lot of information when you start/stop # laptop_mode. VERBOSE_OUTPUT=0 ############################################################################### # 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.

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.

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. ############################################################################### # Should laptop mode tools control which syslog.conf should be used? CONTROL_SYSLOG_CONF=0 # 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. # NOTE: these files are NOT created by default, and if they do not # exist this feature will not work.

Put scripts accepting "start" and "stop" parameters # in the directories /etc/laptop-mode/batt-stop, batt-start, lm-ac-stop, # lm-ac-start, nolm-ac-stop and nolm-ac-start. Laptop mode will call the # scripts in a state-"stop" directory with the "stop" parameter when entering # the state in question, and it will call the same scripts with the "start" # parameter when leaving the state. Scripts in a state-"start" directory are # called with the "start" parameter when the specified state is entered, and # with the "stop" parameter when the specified state is left. ############################################################################### # Should laptop mode start and stop programs? CONTROL_START_STOP=1 ############################################################################### # Settings you probably don't want to touch # ----------------------------------------- # # It is usually not necessary to change these parameters.

Datorita unui bug (tastatura si mouse-ul nu functionau dupa resume) in kernelele <2.6.22, urmatoarele scripturi (cu permisiuni de exec) au trebuit adaugate in /etc/acpi/{resume/suspend}.d
florin@samflorin-laptop:/etc/acpi/suspend.d$ cat 20-i8042-input.sh #!/bin/sh # Unbind the AT keyboard interface. if [ -f /sys/bus/platform/drivers/i8042/unbind ]; then echo -n "i8042" > /sys/bus/platform/drivers/i8042/unbind fi
