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:~$ cat /proc/cpuinfo |grep -i model 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? 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:
Cut here------
Package: * Pin: release o=lupine Pin-Priority: 1000

Cut here-------
- 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.
- 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.
ENABLE_LAPTOP_MODE_ON_BATTERY=1
- Enable laptop mode when on AC power.
ENABLE_LAPTOP_MODE_ON_AC=1
- Enable laptop mode when the laptop's lid is closed, even when we're on AC
- power? (ACPI-ONLY)
ENABLE_LAPTOP_MODE_WHEN_LID_CLOSED=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.
MINIMUM_BATTERY_CHARGE_PERCENT=3
- Disable data loss sensitive features when the battery reports its state
- as "critical".
DISABLE_LAPTOP_MODE_ON_CRITICAL_BATTERY_LEVEL=1
- 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.
ASSUME_SCSI_IS_SATA=1
- Hard drive behaviour settings
- -----------------------------
- These settings specify how laptop mode tools will adjust the various
- parameters of your hard drives and file systems.
- Maximum time, in seconds, of work that you are prepared to lose when your
- system crashes or power runs out. This is the maximum time that Laptop Mode
- will keep unsaved data waiting in memory before spinning up your hard drive.
LM_BATT_MAX_LOST_WORK_SECONDS=600 LM_AC_MAX_LOST_WORK_SECONDS=360
- Should laptop mode tools control readahead?
CONTROL_READAHEAD=1
- Read-ahead, in kilobytes. You can spin down the disk while playing MP3/OGG
- by setting the disk readahead to a reasonable size, e.g. 3072 (3 MB).
- Effectively, the disk will read a complete MP3 at once, and will then spin
- down while the MP3/OGG is playing. Don't set this too high, because the
- readahead is applied to _all_ files that are read from disk.
LM_READAHEAD=3072 NOLM_READAHEAD=128
- Should laptop mode tools add the "noatime" option to the mount options when
- laptop mode is enabled?
CONTROL_NOATIME=1
- Should laptop mode tools control the hard drive idle timeout settings?
CONTROL_HD_IDLE_TIMEOUT=1
- Idle timeout values. (hdparm -S)
- Default is 2 hours on AC (NOLM_HD_IDLE_TIMEOUT_SECONDS=7200) and 20 seconds
- for battery and for AC with laptop mode on.
LM_AC_HD_IDLE_TIMEOUT_SECONDS=7200 LM_BATT_HD_IDLE_TIMEOUT_SECONDS=20 NOLM_HD_IDLE_TIMEOUT_SECONDS=7200
- Should laptop mode tools control the hard drive power management settings?
CONTROL_HD_POWERMGMT=1
- Power management for HD (hdparm -B values)
BATT_HD_POWERMGMT=1 LM_AC_HD_POWERMGMT=255 NOLM_AC_HD_POWERMGMT=255
- Should laptop mode tools control the hard drive write cache settings?
CONTROL_HD_WRITECACHE=1
- Write cache settings for HD (hdparm -W values)
NOLM_AC_HD_WRITECACHE=1 NOLM_BATT_HD_WRITECACHE=1 LM_HD_WRITECACHE=1
- CPU frequency scaling and throttling
- ------------------------------------
- Laptop mode tools can automatically adjust your kernel CPU frequency
- settings. This includes upper and lower limits and scaling governors.
- There is also support for CPU throttling, on systems that don't support
- frequency scaling.
- This feature only works on 2.6 kernels.
- Should laptop mode tools control the maximum CPU frequency?
CONTROL_CPU_FREQUENCY=1
- Legal values are "slowest" for the slowest speed that your
- CPU is able to operate at, "fastest" for the fastest speed,
- "medium" for some value in the middle, or any value listed in
- /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies.
BATT_CPU_MAXFREQ=medium BATT_CPU_MINFREQ=slowest BATT_CPU_GOVERNOR=powersave LM_AC_CPU_MAXFREQ=fastest LM_AC_CPU_MINFREQ=slowest LM_AC_CPU_GOVERNOR=powersave NOLM_AC_CPU_MAXFREQ=fastest NOLM_AC_CPU_MINFREQ=slowest NOLM_AC_CPU_GOVERNOR=powersave
- Should laptop mode tools control the CPU throttling? This is only useful
- on processors that don't have frequency scaling.
- (Only works when you have /proc/acpi/processor/CPU*/throttling.)
CONTROL_CPU_THROTTLING=0
- Legal values are "maximum" for the maximum (slowest) throttling level,
- "minimum" for minimum (fastest) throttling level, "medium" for a value
- somewhere in the middle (this is usually 50% for P4s), or any value listed
- in /proc/acpi/processor/CPU*/throttling. Be careful when using "maximum":
- this may be _very_ slow (in fact, with P4s it slows down the processor
- by a factor 8).
BATT_CPU_THROTTLING=medium LM_AC_CPU_THROTTLING=medium NOLM_AC_CPU_THROTTLING=minimum
- 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.
- 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. You can run the script
- /usr/sbin/lm-syslog-setup to set things up.
LM_AC_SYSLOG_CONF=/etc/syslog-on-ac-with-lm.conf NOLM_AC_SYSLOG_CONF=/etc/syslog-on-ac-without-lm.conf BATT_SYSLOG_CONF=/etc/syslog-on-battery.conf
- Signal this program when syslog.conf has been replaced.
SYSLOG_CONF_SIGNAL_PROGRAM=syslogd
- This is the syslog configuration file that should be replaced by a link to the
- other files.
SYSLOG_CONF=/etc/syslog.conf
- X display settings
- ------------------
- Using these settings, you can let laptop mode tools control the X display
- standby timeouts.
- Should laptop mode tools control DPMS standby settings for X displays?
CONTROL_DPMS_STANDBY=0
- These settings specify the standby timeout for the X display,
- in seconds. The suspend and poweroff timeouts are somewhat
- larger values derived from these values.
BATT_DPMS_STANDBY=300 LM_AC_DPMS_STANDBY=1200 NOLM_AC_DPMS_STANDBY=1200
- Terminal settings
- -----------------
- Using these settings, you can let laptop mode tools control the terminal
- blanking timeouts.
- Should laptop mode tools control terminal blanking settings?
CONTROL_TERMINAL=0
- These settings specify the blanking and powerdown timeouts. Note that
- the powerdown timeout is counted from the moment the screen is blanked,
- i.e. BLANK_MINUTES=2 and POWERDOWN_MINUTES=5 means the screen powers
- down after 7 minutes of inactivity. The range for all these settings is
- 1 to 60 minutes, or 0 to disable.
BATT_TERMINAL_BLANK_MINUTES=1 BATT_TERMINAL_POWERDOWN_MINUTES=2 LM_AC_TERMINAL_BLANK_MINUTES=10 LM_AC_TERMINAL_POWERDOWN_MINUTES=10 NOLM_AC_TERMINAL_BLANK_MINUTES=10 NOLM_AC_TERMINAL_POWERDOWN_MINUTES=50
- Auto-hibernation settings
- -------------------------
- Using these settings, you can make laptop mode tools automatically put your
- computer into hibernation when the battery level goes critically low.
- This feature only works on ACPI, and only works on computers whose batteries
- give off battery events often enough.
- Should laptop mode tools perform auto-hibernation?
ENABLE_AUTO_HIBERNATION=0
- The hibernation command that is to be executed when auto-hibernation
- is triggered.
HIBERNATE_COMMAND=/usr/sbin/hibernate
- Auto-hibernation battery level threshold, in percentage of the battery's
- total capacity.
AUTO_HIBERNATION_BATTERY_CHARGE_PERCENT=6
- Enable this to auto-hibernate if the battery reports that its level is
- "critical".
AUTO_HIBERNATION_ON_CRITICAL_BATTERY_LEVEL=5
- Start/Stop Programs settings
- ----------------------------
- Laptop mode tools can automatically start and stop programs when entering
- various power modes. 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. They are included
- for completeness' sake.
- Change mount options on partitions in PARTITIONS? You don't really want to
- disable this. If you do, then your hard drives will probably not spin down
- anymore.
CONTROL_MOUNT_OPTIONS=1
- Dirty synchronous ratio. At this percentage of dirty pages the process
- which calls write() does its own writeback.
LM_DIRTY_RATIO=60 NOLM_DIRTY_RATIO=40
- Allowed dirty background ratio, in percent. Once DIRTY_RATIO has been
- exceeded, the kernel will wake pdflush which will then reduce the amount
- of dirty memory to dirty_background_ratio. Set this nice and low, so once
- some writeout has commenced, we do a lot of it.
LM_DIRTY_BACKGROUND_RATIO=1 NOLM_DIRTY_BACKGROUND_RATIO=10
- kernel default settings -- don't touch these unless you know what you're
- doing.
DEF_UPDATE=5 DEF_XFS_AGE_BUFFER=15 DEF_XFS_SYNC_INTERVAL=30 DEF_XFS_BUFD_INTERVAL=1 DEF_MAX_AGE=30
- This must be adjusted manually to the value of HZ in the running kernel
- on 2.4, until the XFS people change their 2.4 external interfaces to work in
- centisecs. This can be automated, but it's a work in progress that still
- needs# some fixes. On 2.6 kernels, XFS uses USER_HZ instead of HZ for
- external interfaces, and that is currently always set to 100. So you don't
- need to change this on 2.6.
XFS_HZ=100
- Seconds laptop mode has to to wait after the disk goes idle before doing
- a sync.
LM_SECONDS_BEFORE_SYNC=2

Datorita unui bug in kernelele <2.6.22, urmatoarele scripturi (cu permisiuni de exec) au trebuit adaugate in /etc/acpi/{resume/suspend}.d
---Cut here---
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
End here---
---Cut here---- florin@samflorin-laptop:/etc/acpi/suspend.d$ cat ../resume.d/80-i8042-input.sh
- !/bin/sh
- Rebind the AT keyboard interface.

Deoarece la suspend de foarte multe ori nu mi s-a mai activat partitia de swap, am modificat /etc/fstab si am trecut partitia de swap cu /dev/sdaX in loc de #UUID=97f25d87-fef3-41e1-82b1-3458e93d31e4 none swap sw 0 0
si am adaugat in /etc/acpi/resume.d/99-custom.sh urmatoarele:

/sbin/swapoff -a /sbin/swapon -a
