212.202.189.144: more on ACPI vs. APM

==Preface==

I installed hoary ([[:Category:Ubuntu | Ubuntu]] "unstable") because of some specific needs. Netherless,
this article should apply to Ubuntu 4.10 "The Warty Warthog" too.

Everything seems to work very fine.

See [http://dev.gentoo.org/~brix/papers/X31/X31.html Henrik Brix Andersens] page for a lot of useful information.

==Installing without cdrom or floppy==

Follow the instructions at [http://www.ubuntulinux.org/support UbuntuSupport]: [http://www.ubuntulinux.org/support/documentation/howto/helpcenterhowto.2004-11-26.2137127791/howto_view Netboot remarks ]

==Choosing between APM and ACPI==

Right now there is a crucial feature not working with ACPI on linux (2.6.9): suspend to ram does not switch off the LCD backlight.
Ubuntu ships with ACPI enabled, but without ACPI suspend-to-disk being configured. In effect neither suspend mode is working out of the box.

Simply disableing ACPI at boottime activates APM which works fine with suspend to ram and suspend to disk.

On the other hand: having ACPI disabled will make your system use about 10% more power which reduces my battery
runtime from ~4:00h to 3:40h.

===Disableing ACPI and using APM===

To disable ACPI and activate APM boot your kernel with acpi=off

...describe how to edit /boot/grub/menu.lst...

APM based suspend to disk needs a save2disk.img hibernation file on FAT16. Use the [[tphdisk]] utility to create
this file.

Use Fn-F4 to suspend-to-ram and Fn-F12 to suspend-to-disk.

How to make use of Power Management features

2004-12-07T13:57:48Z

212.202.189.144: /* Suspend to RAM (Sleep) */

==APM==

===general===
You need to enable the APM Power Management support in the kernel and install the [[apmd]] to handle the events triggered by the kernel driver.
The configuration for what to do at the different events is done in the proxy script which is usually found in /etc/apmd_proxy.
See <tt>man apmd</tt> for further information on this.

===Screen blanking (Standby)===
Todo...

===Suspend to RAM (Sleep)===
Todo...

===Suspend to disk (Hibernate)===
The Phoenix BIOS allows you two ways to hibernate with APM: using a special partition or using a hibernation file on a dos type partition.

====using a hibernation partition====
The partition to be used for hibernation must be a primary partition that is at least as big as your laptop's memory including its video ram. First set the partition type of this partition to a0 (IBM Thinkpad hibernation) with fdisk, and then use [[tphdisk]] to write a hibernation file directly to this partition.

Only follow these instructions, if you understand them. You will overwrite a partition on your hard disk and might loose valuable data - consider yourself warned. For example, assume that /dev/hda2 is the partition that is to be converted to a hibernation partition. Become root and type '''/sbin/fdisk /dev/hda'''. At the fdisk prompt type '''t''' to change the partition type, then type '''2''' to indicate that you want to change the type of partition 2, and then enter the partition type: '''a0'''. Now type '''w''' to write the partition table back to disk and exit. After that use [[tphdisk]] to initialize the hibernation partition. First estimate the size of your laptop's memory (main and video). For the sake of this example, let us assume that the main memory is 1024 MB and the video card has 128 MB of memory. Then the command '''tphdisk 1152 > /dev/hda2''' will initialize the hibernation partition. Note that this will only work if the partition is big enough. After a reboot, Fn+F12 will work as expected.

I have successfully used this method on a T41 (2373GEU) that runs Fedora Core 3.

====using a hibernation file on a dos partition====
The partition to put the file on must be a dos or vfat partition. Fat32 formatted partitions have been reported successful as well as Fat16 formatted ones. The file is either created with phdisk.exe, if you happen to have a floppy drive and a bootable dos floppy disk that you can start it from.
Under Linux [[tphdisk]] will do this job for you.

Todo... (how to create the file, partition size)

==ACPI==

===general===
Todo...

===Screen blanking (Standby)===
Make sure you have
*Option "DPMS"
in you XF86Config/xorg.conf.

Running "xset +dpms" and then "xset xdpms force off" will turn off the backlight on a laptop screen. To force a screen off that is using a radeon chipset, install the package "radeontools."

Todo...

===Suspend to RAM (Sleep)===
ACPI Sleep and suspend-to-ram with recent 2.6.x kernels usually works fine, too.

But after a suspend-to-ram (using Linux 2.6.9) the display of the T42p (and probably of other Thinkpads, too) remains black. This can be fixed by adding
"acpi_sleep=s3_bios" to the kernel boot parameter. However I experience some problems with the serial port of the port replicator
after the wake up from ram.

There is a interesting discussion taking place in the [http://bugme.osdl.org/show_bug.cgi?id=3022 OSDL Bugzilla].

===Suspend to disk (Hibernate)===
There are two drivers for this available:
* swsusp, which is in the kernel and
* [http://developer.berlios.de/projects/softwaresuspend/ SoftwareSuspend2] which is more feature rich, but not yet in the kernel, so you have to patch it in yourself
Both are reported to work fine as long as you use open-source graphic drivers. A comparison of the features can be found on [http://softwaresuspend.berlios.de/features.html this page].

Just in case you are in doubt...yes, it is safe in both cases to use the same swap partition as active swap and as suspend partition.

====using swsusp====
Software Suspend (swsusp) is included in the 2.6 kernel series. It seems like no patches for 2.4 kernels are available.

To enable it, go to <tt>Power management options</tt> and enable <tt>Power management support</tt> and <tt>Software Suspend</tt> in the kernel config menu. You'll also want to give the swap partition to suspend to in <tt>Default resume partition</tt>.

In case you prefer to edit your config file directly, you should have the following three entries look like here...
CONFIG_PM=y
CONFIG_SOFTWARE_SUSPEND=y
CONFIG_PM_STD_PARTITION="/dev/resume_partition"
...where <tt>/dev/resume_partition</tt> needs to be replaced by the swap partition you want to use for suspending. (Use <tt>fdisk -l /dev/hda</tt> if unsure.)

You can override the default resume partition anytime by giving <tt>resume=/dev/resume_partition</tt> as kernel boot parameter.
Also, ihn case you suspended, but want to boot up normally (without resuming from the saved image - loosing all data that was unsaved at suspend time), you can give the <tt>noresume</tt> kernel boot parameter.

To suspend you can either do a simple <tt>echo -n 4 > /proc/acpi/sleep</tt> (recommended) or use the [http://softwaresuspend.berlios.de/old-site/swsusp/sysvinit-2.76-v2-for_swsusp-v5.tar.gz patched SysVInit] and call <tt>swsusp</tt> or <tt>shutdown -z now</tt>.

Ideally you would do this from a script like <tt>/etc/acpi/actions/hibernate.sh</tt>. It has proven to be a good idea to shutdown the following processes/drivers within the script before you do the actual suspend.
*any running mysql server
*the madwifi driver, if you happen to use it
Afterwards you might want to enable them again, as well as run a script that does necessary configurations according to the ac power state.
It has furthermore turned out that the system clock is not readjusted automatically, so you will probably also want the do that from that script (i.e. by restarting your systemclock bootup script).

Finally you should take note that swsusp does not set the ACPI S4 state. Instead it goes to S5. This means that the machine itself doesn't know that it was suspend rather than shutdown. Hence you can i.e. boot a parallel installed other operating system and resume your linux session later, as long as you don't touch the swap partition the image was saved to.

===Laptop-mode===
To actually enable the harddrive to shutdown for a longer time and not get started again because of filesystem syncs every few seconds, you'll need to activate [[Laptop-mode]].

==DynamicClocks in the Radeon Xorg driver==
The xorg X server has support for a power saving feature from ATI called PowerPlay. Xorg calls this feature DynamicClocks. It can be enabled in the server by adding '''Option "DynamicClocks" "on"''' in the '''Device''' section in /etc/X11/xorg.conf

Section "Device"
Identifier "Videocard0"
Driver "radeon"
VendorName "IBM Thinkpad"
BoardName "ATI Radeon Mobility M9"
'''Option "DynamicClocks" "on"'''
EndSection

With this option enabled, the X11 server should print (/var/log/Xorg.0.log):

(**) RADEON(0): Option "DynamicClocks" "on"
(II) RADEON(0): Dynamic Clock Scaling Enabled

== tphdisk ==
tphdisk is a small program that enables you to create a save2dsk.bin hibernation file on a fat partition of a phoenix notebios based laptop.
It is a linux replacement for the msdos program phdisk.exe.

=== Project Homepage / Availability ===
http://samba.anu.edu.au/junkcode/#tphdisk

=== Help output ===
Usage: tphdisk <size in MB>
.
written by Andrew Tridgell <tridge@samba.org>
.
.
This program writes a 'save2dsk.bin' hibernation file to stdout. To
use it you should do something like this:
.
1) create a type 16 (Hidden FAT16) partition on your laptop
2) format the partition with 'mkdosfs'
3) mount the partition as VFAT
4) create the 'save2dsk.bin' file on the partition using something like
tphdisk 280 > save2dsk.bin
5) Do a full reboot
.
The only parameter is the size in megabytes of the save file. This
needs to be at least as big as your main memory + video memory, but you
can make it larger if you want to.
.
You should also be able to use this to create a hibernation partition
by directing the output to the right device (eg. /dev/hdaX) and
setting the partition type to A0. I haven't tried this as my thinkpad
doesn't seem to support hibernation partitions.

Right now there is a crucial feature not working with ACPI on linux (2.6.9): suspend to ram does not switch off the LCD backlight.
Ubuntu ships ACPI enabled, but without syspend to disk configuration. In effect there ist no working suspend solution

Simply disableing ACPI at boottime activates APM which works fine with suspend to ram and suspend to disk.

===Installing without cdrom or floppy===
