Dotaz: standby, suspend to ram, ako na to?

[sykora]

mám nainštalované:

hibernate-script-1.02
patchnute jadro je so: software-suspend-2.1.5.7B-for-2.4.28

Po zadaní:

echo 3 > /proc/acpi/sleep 

neurobí vobec nic

Hibernuje bez problémov!! Je možné mimo hibernácie spustiť:

standby,
suspend to ram 

(potrebujem zastaviť disk)?

Aké sú príkazy, nastavenia?

A co vypíše cat /proc/acpi/sleep?

[coques]

myslim, ze ak mas 2.6 jadro mal by si to robit :

echo "mem" > /sys/power/state

popr. "disk"

.. a "3" je suspend to ram, nie ..to disk (to som nikdy nerozbehol)

pri suspend to disk v grube treba pridat resume=/dev/hda3 <= kde mas swap part.

[sykora]

Mám jadro 2.4.8 distribucia MDK, po zadaní:

[root@mdk ondrik]# cat /proc/acpi/sleep
S0 S3 S4 (swsusp) S5

pouzivam lilo a mam tam toto:

image="/boot/bzImage2.4.28"
        label="linux2.4.28"
        root="/dev/hda6"
        initrd="/boot/initrd.img"
        append="resume2=swap:/dev/hda7 devfs=mount hdc=ide-scsi"
        vga=788
        read-only

V

 /etc/hibernate/hibernate.conf

mám standartné nastavenia, nie je potrebné nieco zmenit?

S4 - "Suspend to Disk"

CPU power shut off as in S3, but RAM is written to disk and shut off as well. In Microsoft Windows, the "Hibernate" command is associated with this state. A variation called S4BIOS is most prevalent, where the system image is stored and loaded by the BIOS instead of the OS. Because the contents of RAM are written out to disk, system context is maintained. For example, unsaved files would not be lost following an S4 transition. S4 is currently _not_ supported by the 2.4.x kernel series in Linux, but you might have good luck with SWSUSP. Some machines offer S4_BIOS whose support is considered to be experimental within ACPI4Linux.

hibernate som nikdy neskusal..

skus suspend to disk

 echo "4" > /proc/acpi/sleep

nic za to nedas

apropo, co tak 2.6 jadro? mas system na laptope?

[sykora]

2.6 jadro som skusal ale taky bordel com mi zo sysemu urobil je nemyslitelne. Mozno chyba 2.6.9 kernel. Mam laptom Compaq presario 2100 a podpora suspend v biose nie je

[coques]

ako ti mohlo jadro zo systemu urobit bordel? nie je problem niekde inde?

# a mrkni sem http://www.linux-on-laptops.com/compaq.html

[Josef Kufner]

imho je 2.6.9 jeden z nejlepsich z 2.6 rady. s 2.6.10 moc dobry zkusenosti nemam - byl trosku unstable.

[coques]

s 2.6 jadrom som este nemal problem

kazdopadne nove jadro nemoze urobit zo systemu bordel

 echo "4" > /proc/acpi/sleep

toto sposobilo vypnutie bez opýtania. Bol to hibern, ale neobnovil sa ok, musel stalcit napajanie.

este pridavam moj hibernate conf je to dlhe ale snad mi pomozes to aspon skusit:

# Example hibernate.conf file. Adapt to your own tastes.
# Options are not case sensitive.
# 
# Run "hibernate -h" for help on the configuration items.

##############################################################################
### Choose your Suspend method. You currently have 3 choices:
###
###    swsusp2_15          Software Suspend 2 (requires kernel patches from
###                        http://softwaresuspend.berlios.de/)
###
###    sysfs_power_state   Uses /sys/power/state to suspend (activates pmdisk
###                        on kernels < 2.6.8, or vanilla swsusp otherwise).
###
###    acpi_sleep          Uses /proc/acpi/sleep to activate swsusp, or other
###                        ACPI sleep state supported by your machine.
###
##############################################################################

### swsusp2_15 (for Software Suspend 2)
UseSwsusp2 yes
Reboot no
EnableEscape yes
DefaultConsoleLevel 1
# ImageSizeLimit 200
## useful for initrd usage:
# SuspendDevice swap:/dev/hda2
# LoadSuspendModules suspend_swap suspend_lzf suspend_text
# UnloadSuspendModulesAfterResume yes
## Powerdown method - 3 for suspend-to-RAM, 4 for ACPI S4 sleep, 5 for poweroff
# PowerdownMethod 5
## If you experience hangs on resume due to write caching, try this:
# AsyncIOLimit 128
## Any other /proc/software_suspend setting can be set like so:
# ProcSetting expected_lzf_compression 50
## Or traditionally like this:
# Swsusp2AllSettings 0 0 2056 65535 5
## Or even from the results of hibernate --save-settings with this:
# Swsusp2AllSettingsFile /etc/hibernate/suspend-settings.conf

### sysfs_power_state
## To use /sys/power/state to suspend your machine (which may offer
## suspend-to-RAM, suspend-to-disk, standby, etc) comment out all the options
## above for Software Suspend 2, below for acpi_sleep, and uncomment this line.
## You may replace mem with any one of the states from "cat /sys/power/state"
# UseSysfsPowerState mem
# PowerdownMethod shutdown

### acpi_sleep
## To use ACPI to suspend your machine (via /proc/acpi/sleep), comment out
## all the options above for Software Suspend 2 and sysfs, and uncomment this
## line. The number refers to the ACPI sleep state - 3 is suspend-to-RAM and
## 4 is suspend-to-disk.
# UseACPISleep 4

###   Scriptlets provide support for doing all sorts of things before and after
