Talk:How to make ACPI work

Nirik: /* Auto-wake on lid open - how to STOP? */

{{NOTE|Please sign and date your posts, that is much easier than trying to track down on page history who wrote what!}}

== X41 Woes ==
I have tried the referred patch (Suspend to RAM) with the latest stable kernel (2.6.12.2): Reboot after wakeup.

== T22 Woes ==

Has anyone managed to get this working with a T22? The BIOS is upgraded, but it _never_ wakes up from sleep. Neither lid nor pwr button are noticed by the system.

--Are you in suspend2ram? This works fine for me. I think you have to enable it in BIOS.

== Sound-after-suspend not working with Mandriva 2006 ==
With Mandriva 2006, suspend/resume works with ACPI, but sound quits working.
This happens with the T20 and T22. The recommended Mandriva trick of setting "RESTORE_SOUND=yes" in the "suspend" script doesn't solve this. Other suggestions? - MarkStosberg mark@summersault.com

== Solutions ==
I had 2 different issues:
- with my X21 I had to unload the alsa modules before suspend.
- with my x23 I have to change the mixer settings to get it working again.

(I hope it will help)

== CIFS ==
Hi all,

I have found out that if I use cifs to mount Samba shares, I get lots of problems with suspend/hibernate (the cifsd breaks the shutdown process). Maybe it would be good to warn about this.

== Auto-wake on lid open - how to STOP? ==

Anybody have any idea how to stop the machine (a T43p) from automatically waking up on lid open? My /etc/acpi/events only has a lm_lid file which is commented out - it should do nothing, and there is no plain 'lid' event. Is lm_lid an event only activated when in laptop-mode?

----

That's a good question, but I have the opposite problem: my T43 (2687) won't wakeup from S3 (suspend-to-RAM) when I open the lid, which is exactly what yours do, and what I wanted mine to.

Yes, I have the same problem - this 'feature' is exhibited in both O/S's on my T43p... I tried everything I could think of to stop it (changing/deleting the acpi event handlers, etc). There does not seem to be any BIOS option to "wake up on lid open."

It has irritated me less over time; I find myself now using suspend if I don't want the feature, and sleep mode only if I anticipate that I will open it up and use. After all, suspend is pretty quick with 1 GB ram.

Just a note...the term "suspend" refers to both, suspending to RAM and suspending to disk, the counterpart to the "sleep" term is "hibernate". We should try to stay clear about this everywhere to avoid confusion.

There is a /proc/acpi/wakeup file here. (t42p). Currently shows:
Device Sleep state Status
LID 3 * enabled
SLPB 3 * enabled
PCI0 3 disabled
UART 3 disabled
PCI1 4 disabled
USB0 3 disabled
USB1 3 disabled
AC9M 4 disabled

Echoing the 4 letter code toggles that device as a wakeup device.. ie:
root# echo " LID" > /proc/acpi/wakeup
root# cat /proc/acpi/wakeup
Device Sleep state Status
LID 3 *disabled

Does that work for any of you guys?

Talk:Script for enabling the fingerprint reader with BioAPI

2006-03-29T01:39:44Z

Nirik:

With only 2 minor changes this script works on fc5 as well...

You need to change the line that says:

grep -q 'Fedora Core release 4' /etc/redhat-release || { echo \

to say:

grep -q 'Fedora Core release 5' /etc/redhat-release || { echo \

Also, you need to add a patch for the bioapi to get it to compile on fc5 with gcc4.1:

---cut--
diff -Nur bioapi-1.2.2.orig/addins/dl/mds/dal_classes.h bioapi-1.2.2/addins/dl/mds/dal_classes.h

+ CSSM_RETURN GetDBNamesAndParameters(
CSSM_DL_DB_HANDLE DLDBHandle,
DAL_DB_OPEN_PARAM_PTR pParam);
};
--cut--

I added a line to apply this patch:

...
tar xjf bioapi-latest.tar.bz2
pushd bioapi-1.2.2
patch -p1 < ../bioapi-gcc41.patch
./configure --with-Qt-dir=no --prefix=$WHERE
...

Can anyone else confirm that works and perhaps merge into the main script?

Great, great work! Really! This completely rocks. I just stopped my battery from charging at 77% and restarted charging a bit later, no problems whatsoever. BTW, this is on kernel 2.6.14.3.

None of the fuctions is working on my T40, kernel 2.6.14-mm2.

--[[User:Lammic|lammic]], 2005.12.05

Works for me on a T41 running 2.6.12-10-686 (Ubuntu 5.10).

--[[User:berndtnm|berndtnm]], 2005.12.06

Including stop_charge_thresh? That one seems to be missing on the T42p.

tp_smapi works just fine on an R52 with Ubuntu Breezy stock kernel.

''To set the thresholds for starting and stopping battery charging (in percent of current capacity):''

'''current''' really? That'd be weird, I'd expect it to be percent of '''total''' capacity.

--[[User:Micampe|Micampe]] 14:39, 7 Dec 2005 (CET)

"Current full charge capacity", as opposed to "current remaining capacity" or "designed full charge capacity"...

Battery features don't work with my T41p. I can't check this with windows. Can anybody try these features?

-- Nils, 7 Dec 2005
----

Nils, does cdrom_speed work for you on the T41p? Could you provide the details requested in the README (dmesg etc.)?

--[[User:Thinker|Thinker]] 21:57, 7 Dec 2005 (CET)
----

CDRom Speed seems to work. (I see no warnings, but I have to do a speed test.) Now, I've send all outputs to the email-address in the readme.

-- Nils, 8 Dec 2005
----

All the features except the stop_charge_thresh seem to work here on a t42p.
One note, the start_charge_thresh seems to really be stop_charge_thresh. Ie, If I set that to lower than my current battery %, it will never charge,
and if I set it to 100 the battery charges all the way.

==Changing the CD speed when the CD is being accessed will hang your computer==

I don't have this problem on my T40p. CDROM is mounted and file on CD is opened. Change speed do '''not''' hang my system.

-- Stefan Schmidt
----

An open file looks fine if you're not reading/writing at that point. But my T43 does hangs on this:
# dd if=/dev/scd0 of=/dev/null &
# echo 1 > /sys/devices/platform/smapi/cdrom_speed

--[[User:Thinker|Thinker]] 16:41, 7 Dec 2005 (CET)

OK, sorry. I was to fast. My system hangs on this commands, too. :(

-- Stefan Schmidt

Works well. Great.

T42 2373-8zh. Working :cdrom_speed and start_charge_thresh. Untest : inhibit_charge_minutes.

-- Haifeng Chen

cdrom_speed works on my T40.

== "thinkpad" module kernel compatibility ==

Ajunge, how do you compile the "thinkpad" module compile on kernel >=2.6.9? The latest thinkpad version (5.8) still uses "get_cpu_ptr" and "set_cpu_ptr", which were removed in 2.6.9.

Wonderful idea! And works perfectly on my T43p, scared the cat away. ;)

Good, so it's at least a cat deterrant! A friend of mine had a nasty incident involving a laptop and a cat...

I had to tweak the line that reads the position file. My position file has - numbers in it for some reason, so:
m/^$-(\d+),-(\d+)$$/ or die "Can't parse $pos_file content\n";

After that change it works great.
It scared the dogs away here. ;)

Fixed. Which ThinkPad model, BTW?
