How to make ACPI work

2005-06-02T01:26:30Z

Gologs: /* using SoftwareSuspend2 */

==general==
===Kernel configuration===
First of all you'll have to enable ACPI support in your kernel (if your distro doesn't already have an ACPI enabled kernel).
To do this open your kernel config, go to <code>Power management options</code>, enable <code>Power Management support</code>, go to <code>ACPI</code> and enable the needed options. You'd most likely want to enable <code>Sleep States</code>, <code>AC Adapter</code>, <code>Battery</code>, <code>Fan</code>, <code>Processor</code> and <code>Thermal Zone</code>. Then recompile your kernel.

If you prefer editing your .config file directly, you should set at least the following variables:
CONFIG_PM=y
CONFIG_ACPI_BOOT=y
CONFIG_ACPI_INTERPRETER=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_SLEEP_PROC_FS=y
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
CONFIG_ACPI_BUTTON=y
CONFIG_ACPI_FAN=y
CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_THERMAL=y
CONFIG_ACPI_BUS=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_PCI=y
CONFIG_ACPI_SYSTEM=y

===IBM specific ACPI driver===
Unfortunately, special drivers for ACPI on ThinkPads were not included with kernels prior 2.6.10.<br />
So you'll have to compile one yourself or get it as precompiled module for your kernel.<br />
You have the choice between [[thinkpad-acpi]] and [[ibm-acpi]], with the latter being the recommended one.<br />
If you use a post-2.6.10 kernel and you want to use [[ibm-acpi]], it is recommended to look on its projects page for a possibly newer version.<br />
In general it is a good idea to read the README included with the driver.

===ACPI daemon===
Also you'll need to install [[acpid]], if it isn't present on your system. [[acpid]] is a daemon that handles the ACPI events generated by the system. Read [[How to configure acpid]].

==Screen blanking (Standby)==
Make sure you have
Option "DPMS"
in the Monitor section of your XF86Config/xorg.conf.

Running {{cmd|xset +dpms}} and then {{cmd|xset dpms force off}} will turn off the backlight on a laptop screen.<br />

Note that this may not work in combination with {{cmd|echo -n "mem" > /sys/power/state}} because switching to console causes the backlight to come back on before sleeping.

==Suspend to RAM (Sleep)==
ACPI Sleep/suspend-to-ram with recent 2.6.x kernels usually works fine. Have a look at the [[How to configure acpid|acpid configuration HOWTO]]. It includes a specific example for going to sleep on lid close.

The following glitches may or may not occur in relation to suspending to RAM:
* With a 2.6.9 or 2.6.10 kernel, when resuming from a suspend-to-ram the display might remain black (the system is still rebootable via ctrl-alt-del). This can be fixed by adding <tt>acpi_sleep=s3_bios</tt> to the kernel boot parameters. It seems this problem is solved in 2.6.11-rc1.
* When your system is equiped with a Radeon Mobility graphic controller your [[Problem with LCD backlight remaining on during ACPI sleep|LCD backlight may not turn off automatically]]. Use [[radeontool]] to switch off your backlight prior suspend in your sleep action script.
* Also, you might want to take note of the [[Problem with high power drain in ACPI sleep]].
* You may experience problems when using {{cmdroot|echo standby > /sys/power/state}} (machine goes to sleep and wakes up immediately). This can be avoided by using {{cmdroot|echo -n 3 >/proc/acpi/sleep}} to get it to sleep. This can be also happen if hotplug daemon is still running.
* Problems with the serial port of the port replicator after the wake up from ram have also been experienced.

==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 {{cmdroot|fdisk -l /dev/hda}} if unsure.)

You can override the default resume partition anytime by giving <tt>resume=/dev/resume_partition</tt> as kernel boot parameter.
Also, in 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 {{cmdroot|echo -n 4 > /proc/acpi/sleep}} (recommended) or use the [http://softwaresuspend.berlios.de/old-site/swsusp/sysvinit-2.76-v2-for_swsusp-v5.tar.gz patched SysVInit] and call {{cmdroot|swsusp}} or {{cmdroot|shutdown -z now}}.

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 linuxant driver may require stopping in a acpi script as well. {{cmdroot|dldrstop}} does the trick.

Afterwards you might want to enable them again, as well as run a script that does necessary configurations according to the ac power state.
Furthermore, 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).

If the sound output is silent after resume, these commands might help to get sound to work again without reloading any modules:

amixer set Master mute >/dev/null 2>&1
amixer set PCM mute >/dev/null 2>&1
amixer set Master unmute >/dev/null 2>&1
amixer set PCM unmute >/dev/null 2>&1

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.

===using SoftwareSuspend2===
First apply Software Suspend 2 patches from http://softwaresuspend.berlios.de/ if they are not already in your kernel. I am running 2.6.11-rc4-nitro in a Thinkpad T30 2366.

Be sure to also read the http://softwaresuspend.berlios.de/HOWTO.html

These are the options for the kernel. You can change the <tt>/dev/hda5</tt> to your swap partition

# Software Suspend 2
CONFIG_SOFTWARE_SUSPEND2=y
CONFIG_SOFTWARE_SUSPEND2_BUILTIN=y
CONFIG_SOFTWARE_SUSPEND_SWAPWRITER=y
CONFIG_SOFTWARE_SUSPEND_LZF_COMPRESSION=y
CONFIG_SOFTWARE_SUSPEND_TEXT_MODE=y
CONFIG_SOFTWARE_SUSPEND_DEFAULT_RESUME2="/dev/hda5"
# CONFIG_SOFTWARE_SUSPEND_KEEP_IMAGE is not set
CONFIG_SOFTWARE_SUSPEND_CHECK_RESUME_SAFE=y
# CONFIG_SOFTWARE_SUSPEND_DEBUG is not set
# CONFIG_SOFTWARE_SUSPEND_DEVELOPER is not set

Next, compile and install the kernel

In the meantime, add the following to the kernel parameters <tt>resume2=swap:/dev/hda5</tt>. Again change <tt>/dev/hda5</tt> to your swap partition.

Install the hibernation script

For [[:Category:Gentoo | Gentoo]] users: emerge hibernate-script<br />
For [[:Category:Fedora_Core | Fedora Core]] users: kernel and hibernate RPMs are available at http://mhensler.de/swsusp/<br />
For all other users, check the home page for packages (deb, i386 rpm, tgz, and source rpm) from http://softwaresuspend.berlios.de/

Debian users using initrd image, make sure you copy [http://dagobah.ucc.asn.au/swsusp/2.0.0.102/swsusp-initrd.sh swsusp-initrd.sh] script to your /etc/mkinitrd/scripts directory before creating initrd image.

Restart using the new kernel and run the script to test it out.

Problem with high pitch noises

2005-04-20T23:11:29Z

Gologs: /* Solutions */

Information on strange high pitch, low volume noises emitted by ThinkPads.

==Problem description==
Even though ThinkPads are known as very silent notebooks, they tend to emit different, mostly high pitch noises in certain circumstances. The noises are of low volume and hence not realized by everyone or at least tolerated by most people. However, there are those with "bat like ears" that hear them and might be annoyed by that.

==Affected Models==
Noises have been experienced in the following situations:

==Affected Operating Systems==
*Linux, all flavours

==Status==
Similar phenomena was experienced with models from the T2x aera, like i.e. on the [[:Category:T23 | T23]]. On these models the problem was related to the graphics circuitry and occured especially or only while making use of DirectDraw funktions. IBM was able to fix it through a BIOS upgrade.

It is likely that the noises discovered on recent models are related to the graphics chip as well.

==Solutions==
From Martin Steigerwald: I made the observation that I get at least less high pitch noises on my ThinkPad T23 when I do not use the two ACPI modules "processor" and "thermal" (depends on the first one). I have no clue, why. Anyone with similar experiences?

Niko Ehrenfeuchter: I'm experiencing the same here on my X24. Removing the "processor" module also stops the pitch noise, which does ONLY occur when setting the CPU to maximum speed (using cpufreq). On low speed it's completely silent, even having loaded the processor module.

Rolf Adelsberger: I can confirm this: the high pitch noise is only remarkable (at least with my ears ;-) ) if the processor speed is set to maximum frequency.

Andreas Karnahl: i've read in several forums it has something to do with the "idle"-state (or "C3") of the processor. there is a frequency called "timer interrupt" (or something like that). since kernel 2.6x it is set to 1000 Hz by default (compared to 100 Hz in Kernel 2.4x). the exact reason i don't no. but it is save to change this frequency to 100 Hz in kernel 2.6x (by the way, windows up to XP uses 100 Hz by default).

just do the following:
in [path to kernel-sources]/include/asm-i386/param.h:
#define HZ 1000
change the value of HZ to 100:
#define HZ 100

... and compile the kernel ...

after i changed it on my ThinkPad A30 (under SuSE 9.2 and 9.3) and recompiling the kernel the high pitch noise is gone away.

Joern Heissler: I made another experience. I played around with linuxant conexant [[modem]] drivers. After loading them I got some noise on my t42p

Naheed Vora: My T41 (2373-268) started to give high pitch noise ocassionally, when I upgraded to 2.6.11 kernel. I tried to unload lot of modules but finally figured out that disabling bay stops the noice.

If you have ibm_acpi module, do (Need a cleaner solution):
echo eject >/proc/acpi/ibm/bay
