the keyboard don't work perfectly on laptops acer travelmate 2300 series with Dapper

[Louis XVI with a gun]

The keyboard is capricious, it often refuses to type a letter or when one presses once on the key, there leaves three times the same letter . There are no particulars conditions so that that occurs , it ' s permanent

[Patrice Vetsel (vetsel-patrice)]

Is it only under ?. Could you try under a text terminal (ctrl+alt+F1).

Can you confirm whether or not this happens on another distribution of Linux or a different OS? Somehow this doesn't sound like an Ubuntu bug....

[Louis XVI with a gun (anthony-guichard)]

I have this problem only on ubuntu dapper drake . On suse , mandrake ,
ubuntu 5.10 I didn ' t have this problem .
When my travelmate was powered with ubuntu breezy badger I didn ' t have
this problem
nb : I stay with dapper because the travelmate have now acpi support
maybe it s an acpi problem that affect the keybord .....

Hello,

I have an acer travelmate 2300 and i've also the same problem (just with dapper darke), the problem worsens whene I lanche adesklets... the keyboard and the touche pad become crazy ...

nb: ACPI support works fine.

[Mohammed (gnucoder)]

I think that is a major problem, because the laptop is not usable without keyboard and touche pad

[FredericVDE (fred-mentalwarp)]

i also have this bug with an acer aspire 1500. (lost and stuck keys)

it broke maybe one or two week ago. It was fine before (on dapper)

[Michael Sheldon (michael-sheldon)]

I'm experiencing this problem with an Acer 1514. Outside of X keys are skipped, inside X keys are both skipped and repeated (looks to me as if the release signal isn't being sent, since pressing the key again will usually stop repeating and other keys can be pressed whilst it repeats). This worked correctly in Breezy.

[Michael Sheldon (michael-sheldon)]

Under further investigation this appears to be primarily an X bug. Booting with the previous kernel (from Breezy, 2.6.12-10) results in the same behaviour.

[Matt Zimmerman (mdz)]

This report is very unclear. Do you have problems outside of X or not?

Can anyone confirm which version of the kernel introduced this regression?

[Michael Sheldon (michael-sheldon)]

There are minor problems outside of X (occassional key skips), and major problems inside X (frequent key skips, key repeats). The problems inside X only occur with Dapper (using both 2.6.15 and 2.6.12), the problems outside of X occur under both 2.6.15 and 2.6.12.

[Louis XVI with a gun (anthony-guichard)]

I have this problem with a kernel 2.6.19
but with the dapper flight 4, without updating the installed operating
system from the cd, I didn ' t have this keyboard problem.

[Paul Sladen (sladen)]

I suspect this might be the same as bug #21558. Can you try booting with:

  i8042.nomux=1

on the kernel command line and see if that fixes it.

[Louis XVI with a gun (anthony-guichard)]

I have tested the command line i8042.nomux=1 in grub and IT SEEMS that it
fixes the problem. The keyboard seems to work perfectly but I don ' t know
what is the résult under KDE were the problem is generally amplified

[FredericVDE (fred-mentalwarp)]

I have tested the proposed fix, and it didn't worked. I still have the same keyboard issues (Acer 1500, gnome, ubuntu dapper with latest updates)

[Mohammed (gnucoder)]

I have tested the proposed fix, and it didn't worked for me too (Acer TravelMate 2300, Gnome, ubuntu dapper), I've noticed that the problem is enhanced while using aDesklets, so the keyboard become barely useless.

[Paul Sladen (sladen)]

If it is related to the proposed fix above then it is caused by a buggy Embedded Controller. The same chip is responsible both for power-management and for controlling the internal keyboard. When it is queried for the battery status and a key is held down or the mouse is in action the result is dropped packets and corruption of the i8042 stream.

It is likely that KDE or ?Desklets contains a battery status applet that probes for the battery status more frequently.

[Mohammed (gnucoder)]

@Paul Sladen : confirmed, I disabled the battery modul in the system monitor aDesklet. Runnig aDesklets does not have any more effect on the problem. But my keyboard is always crazy even with the line (i8042.nomux=1) in grub.

[Louis XVI with a gun (anthony-guichard)]

I confirm that the problem of keyboard is ever present after a day of
utilisation of my keyboard

I upgraded with the kernel version 2.6.15-21-386 and I have ever the
keyboard problem
It seems that the problem wasn' t present with the dapper flight 4 (kernel
version 2.6.15-15-386) but I need a confirmation

I tested with the kernel version 2.6.15-15 and the keyboard have ever the
same problem
Could the problem be directly in the acpi support ???

hi, the kernel update to the version 2.6.15-22 didn' t resolve the keyboard
problem, The problem is ever present with the line i8042.nomux=1 in grub
and, the problem is amplified under XGL

[Aldones (julien-zagata-info)]

Hi

Same problem here with an Acer Travelmate 4001Lmi.
I'll give a try with the i8042.nomux=1 option
Hope it'll work ;)

[Karl-R. (k-r-ernst)]

I had the same Problem on ACER Travelmate 4002WLMi with Breezy, but now it seems to work while I'm using Dapper

[Louis XVI with a gun (anthony-guichard)]

The problem is similar to the bug #39315 is thère a solution ???

[Matthew Lange (matthewlange)]

This seems to be the same as Bug 39315.

[mh (mamh)]

The same problem with my acer travelmate 2303lm. sometimes skipping of letters and then repetitions of letters. I m not sure, but i think to aktivate and deactivation of the touchpad suppresses the problem of repetitions of letters but not skkipping.
I m using Kubuntu 6.06. The Problem occurs also in Xubuntu 6.06. No such problems with other distributions or versions - ubuntu 5.10, 5.04, suse 9.3-10.1... And maybe really a problem of battery-status. Because this is the first-time linux recognizes my smart-battery - but can be chance too.

[Kousik Nandy (kousiknandy)]

> And maybe really a problem of battery-status. Because this
> is the first-time linux recognizes my smart-battery -

Exactly. That is the culprit. If you remove the smart battery module, you can restore sanity of your keyboard. I think this kernel got the smart battery patch but not the embedded controller one. So the workaround:

sudo rmmod acpi_sbs

But this will turn off battery monitoring too.

[Spoilerhead (spoilerhead)]

confirming missing keystrokes on a acer travelmate 4001 with fresh installed dapper

maybe its in some relation to
http://sourceforge.net/mailarchive/forum.php?forum_id=6102&max_rows=25&style=nested&viewmonth=200509
(look for nospinlock)

[Spoilerhead (spoilerhead)]

add: not presend in 2.6.16, but there my battery doesn'T get recognized, so its definitive soemthing with the ubuntu applied patches

[Ben Collins (ben-collins)]

As you should notice, this bug is a duplicate, and the bug that it duplicates is fixed in our current kernel, which should be available to the public via an update to dapper within a few days.

[Spoilerhead (spoilerhead)]

oh, sorry, my fault.

[mh (mamh)]

the bugfix in the new kernel 2.6.15-25-386 for Bug 39315 obviously didn´t work for acer travelmate (maybe also aspire) laptops. see Bug 39315. i´m not sure, if the last bugfix fixed the problem of bug 39315 because by now there is no feedback from anyone. just some users report, that the problem is still not fixed.

[Nick (nickvd)]

I TOO have an Acer Travelmate 2300 and have been getting really frustrated with this bug... i havent tried the nomux=1 fix, but i am running the latest kernel:
$ uname -a
Linux exile 2.6.15-25-386 #1 PREEMPT Wed Jun 14 11:25:49 UTC 2006 i686 GNU/Linux

Reverting back to Breezy is just not acceptable, apci support is just too important to lose. I really hope this gets squashed soon, as i use this system for development and it's causing a bunch of minor bugs in my apps if i dont notice the missing keypress...

Please let me know if there is any info i can provide, I hereby volunteer to be a guinea pig if need be... :)

[Matthew McEachen (mrm-ubuntu)]

Have you tried, as a ugly workaround, unloading the modules mentioned in the kernel bug report?

Edit /etc/default/acpi-support's MODULES and add

sbp2 ohci1394 ieee1394 ehci_hcd uhci_hcd usbcore

And while you're at it, add a "sync" call to the end of /etc/acpi/prepare.sh (to make sure the disk cache buffers are clear before acpi suspend fails and your FS has to replay logs)

The new kernel should not require the 1394 modules to be unloaded, as I understand it.

[Nick (nickvd)]

the following seemed to work, but I took a break and havn't done much typing:

rmmod acpi_sbs
rmmod i2c_acpi_ec

I added them to /etc/rc.local so it'll remove the modules on boot, but this is only going to be a temporary workaround as having the battery meter is VERY important to me...

[Nick (nickvd)]

I can now confirm that the above workaround did fix the problem, however as i said, acpi is very important...

[Lesack (lesack)]

I can confirm that this bug is still present in
2.6.15-26-386, although the workarounds shown above make it less severe.

[mh (mamh)]

Hello!

I do not use Ubuntu anymore because of this keyboard-problem. I heard about an update with many bug-fixes - did any bug-fix fix this problem? I would be grateful, if anyone can report, if this bug is fixed.

[Paul Sladen (sladen)]

mjg59: is there a way to enforce single-threaded ACPI usage, that can be tried?

[Christian Schürer-Waldheim (quincunx)]

I still have this very annoying problem on my Dell D620 with Intel Core 2 Duo.
Kernel is: 2.6.17-10-generic #2 SMP Fri Oct 13 15:34:39 UTC 2006 x86_64 GNU/Linux

I've unloaded acpi_sbs, battery, I've even removed the battery but still have this problem. Please, is there any fix?

[[e-mail] (ghostdogtree)]

Had the same key repeat problem on edubuntu 6.06.1
On an underpowered compaq pres with amd k6
Was unable to even enter user name etc
switched to terminal log on.
entered as root.
ran
rmmod acpi_sbs
rmmod i2c_acpi_ec
as sudo.
Problem solved for now.
I had a same issue with ubuntu under kde but not gnome
