Keyboard stops working randomly [SOLVED]

Message

srunni · Post by **srunni** » Tue Sep 09, 2008 1:18 am

Hi,

I'm running KDE 3.5.9, and sometimes my keyboard just randomly stops working (my mouse is fine). If I log out, my keyboard is working again. There doesn't seem to be any pattern to when this problem shows up. Any ideas?

Thanks!

Do you have something inside /var/log/messages

conky, what is that. When he segfault, maybe it crash the keyboard driver inside the memory...

srunni · Post by **srunni** » Tue Sep 09, 2008 2:29 am

Conky is a system monitor which runs on my desktop. It regularly segfaults, and I've never bothered to figure out why. I don't think that's the problem though. But I'll try to figure out what's wrong with it and fix it in case it is.

d2_racing · Post by **d2_racing** » Tue Sep 09, 2008 2:59 am

Can you disable this conky and try if you keyboard will crash again ?

srunni · Post by **srunni** » Tue Sep 09, 2008 9:25 pm

I just had this error again, and it is not due to Conky. Conky's segfaulting during the logout procedure. I looked at the time before logging out, it was 16:22. Here are the messages for the 10 minutes before that:

It is most likely right before the ``session closed for user root'', because I had to kill a Konsole window running an emerge to log out.

Hi, are you having some problem with your wifi also ?

srunni · Post by **srunni** » Wed Sep 10, 2008 1:43 am

No, I'm not using wifi - I'm using my wired connection. I have the wifi switch turned off, so the hardware should be completely disabled. Wifi is a little flaky when I use it though (wpa_supplicant + Wicd).

You have a lot of error about your wifi :

Look at the time. I logged out at 21:17:27. The error occured within 30 seconds before that. The error is not being logged.

Some times ago i got the same problem, now it's gone.
when it happens, try to open a terminal and press a key for very long time (10 seconds), and see if the character appears in the terminal.
If so, you have the same issue, but i can't provide a solution, sorry.

srunni · Post by **srunni** » Wed Sep 10, 2008 5:25 pm

Thanks for the help, I'll try that the next time it happens.

srunni · Post by **srunni** » Wed Sep 10, 2008 9:49 pm

So I had the problem again, and what you said worked - I could only type into the terminal, and only after holding down the key for a significant amount of time.

kokoko3k · Post by **kokoko3k** » Thu Sep 11, 2008 7:12 am

Of course is something X related (ctrl-alt-backspace, if you manage to hit them, will solve the problem, termporally), i'd try to upgrade or downgrade xf86-input-keyboard first...

Just curious, which keyboard do you use? mine is a wireless logitech desktop pro.

Does X control the login/logout from KDM? Or is all that behavior transparent to it and handled by KDE? In that case, wouldn't it be a KDE problem? Were you using KDE when you had the same problem?

This is a laptop (HP Pavilion dv9700t), and I'm using the built-in keyboard. I will try connecting an external keyboard to see if it works (though I believe I tried that a while back and it didn't).

When you log out from kde and return to kdm, X is restarted too.
Yes, i use kde, and it could be a kde issue, but my problem vanished and i've not upgraded any kde part, so i bet is an X issue.

I finally figured out what was going on. Apparently, activating KDE's ``slow keys'' and ``sticky keys'' features via a gesture (not sure if mouse or keyboard) was enabled. All I had to do was go to KControl --> Regional & Accessibility --> Accessibility --> Activation Gestures and disable ``Use gestures for activating sticky keys and slow keys''. I guess that restarting X was resetting this option.

Disabling "slow keys" also worked for me (kde4.1) thanks

The same thing happened to me once yesterday in KDE 4.1.2 aswell.

pcfreak85 · Post by **pcfreak85** » Sun Nov 16, 2008 3:01 pm

same issue here with 4.1.2, slow keys is already disabled.
