[solved] weird keyboard behaviour

nblock · 2009-12-02 16:12:48

Hi,
i do have a strange problem with my keyboard. Sometimes (i can't reproduce this) the keyboard hangs. For example: if i type an 'a' i get a lot of 'a's on my screen. This is not limited to letters, same happens when pressing the 'enter' or 'backspace' or multimedia-keys.
The magic stops when pressing 'esc'.

A college has the same problem, so i believe that my keyboard is not broken.

kernel: Linux malcolm 2.6.30-ARCH
xorg-server: 1.7.2-2

I couldn't find anything related in the logs.
Any ideas?

Which keyboard is it?

nblock · 2009-12-02 16:32:07

logitech multimedia keyboard 600 or "internal" keyboard of hp nx6325.

both have this problem.

Does the error occur only in X or also at the console?

nblock · 2009-12-02 16:53:26

i never had this problem on console. But i must also say that i work very rarely on console...

Are you using input-hotplugging or is your keybard set up in xorg.conf?

nblock · 2009-12-02 17:08:50

hotplugging. i had this problem for a pretty long time (i guess since xorg-1.7.x) but i always thought. that this might be a hardware problem.

miau · 2009-12-02 17:10:09

Have you tried to disable hotpluging and use the kbd driver instead of evdev?

nblock · 2009-12-02 17:51:00

no, not yet. But hotplugging worked for me since 1.5.x.
I don't believe, that this is the problem. Otherwise i would have had the same behaviour in older versions of xorg.

miau · 2009-12-03 06:38:25

Maybe you could create a new user and test if the error does still occur. Maybe its a configuration problem.

Same problem here (on my laptop and desktop). I'm using latest versions of all packages (keyboard by hotpluging). Sometime system hangs on repeating a single key and sometimes it repeats combination of keys like ctrl+v. I've noticed this about 10 days ago.

same for me, for about one week, on 2 different systems. I'm using KDE4 but some other people reported this problem on Gnome too. It generally stops when I strike the key again a few times.

It happened when I showed someone how cool Linux was, and then it opened 60 occurences of the same images I wanted to cut and paste...

+1
I'm using a notebook here. I started having problems a little while ago, fortunately the 'stuck' keys problem doesn't happen too often but when it does its not pretty, specially if I've used enter to open a file.

i have the same problem using a fully updated archlinux 64 in my lenovo R61.

Happens to me too. This started happening maybe a week or two ago for me. I update once or twice a week.

webnull · 2009-12-05 10:14:33

I have the same problem on HP Pavilion DV6110ea.

Confirming the same problem on Acer Aspire 4710.

Started noticing it after the X.org 1.7 upgrade. Mostly the Tab key gets stuck - in Firefox and the text editor, and would be solved after pressing Escape or the same Tab key again. But sometimes, the keyboard would totally freeze over after this "Double Tab" issue.

webnull · 2009-12-05 20:54:06

I have also problem with "ALT" key, but its not freezing but sometimes its automatically pressed by "nobody" and when i try to select text im moving a window.

Same thing here. Does not seem to be caused by anything in particular. It's more like as if the key event handler got stuck somehow (such as, say, registering one "key down" event, waiting for a "key release" event to match it, but instead finding another "key down" event, and waiting for a "key release" event for THAT, blocking the original wait. But nobody writes keyboard event handlers like that, right?).

patson · 2009-12-06 09:34:29

There seems to be a bug report for this very problem. It also appears nobody has a clue as of yet as to why this is happening.

oh guys, I thought it is something wrong with my keyboard. I am happy that I am not alone

I got the same problem after some upgrades... don't remember what exactly I upgraded. there were a lot last time> 2.28

alessandro_ufms · 2009-12-07 10:47:39

I have the same problem here. I've been downgrade xorg to 1.7.1.901-2 and the problem is gone. Hotplugging here too.

Yup, same problem here on both 32- and 64-bit. It seems to me to be easier to duplicate using Geany for some reason. But maybe that's just because I am typing a lot in there!

nblock · 2009-12-07 14:53:06

The problem happens more often, when working with dolphin and do some cut-and-paste with files.

rulex · 2009-12-07 15:07:17

same here, also sometimes keycombinations like ctrl+alt+X gets stuck (all of them) until one of them is pressed

it started with xorg-server 1.7.1.902-1 so I downgraded to 1.7.1.901-2 and the problem was gone.

anyone tried 1.7.3-1 ?
