The keyboard became dead on KDE

Hi ! I was typing a message on the browser Bon Echo and no new caracter was appearing anymore when I pressed a key. Unable to switch virtual desktop by pressing Ctrl+Fn, the keyboard was dead, only the mouse was working. I closed the session. I probably press a shortcut by accident, but witch one and how can I recover the keyboard fonctionnality after that?

I've had this happen to me before (on Kubuntu at work). I never figured out what the cause was, but going into the keyboard settings and changing settings around (I think sticky keys on, apply, and then off again worked) got it working again.

I thought it was kind of crappy.

I've had this happen too. Exit KDE, the keyboard is functional, type startx and away you go.

I don't think it's the hardware, because when the keyboard is in the "failed" state I still get a fake keyclick on the PC speaker for each key press.

As arghnoname says, it's not the behaviour one would wish from high-quality software.

I'm seeing this problem too from time to time - keyboard stops responding, but pressing Capslock or NumLock does activate the corresponding LED, mouse functions normally. Usually goes away after some clicking around, at worst have to restart X. Nothing suspicious appears in the logs. Xorg 7.1, KDE 3.5.5, PS2 Logitech keyboard on amd64.
One thing - it's more likely to happen after resume from suspend to RAM (S3).

I too had this happened three times so far lately. I read in some of the new changelogs for the latest kernels that there has been a fix for a similar problem.

I'm on vanilla-sources 2.6.17.13. If it's a kernel problem the fix has not reached this version. Encouraging.

I am still having this problem.
I am using ck-sources 2.6.19, amd64.
The problem seems to come after some time of inactivity. If I walk away from the computer and come back. I have had this happen maybe 5 times for the last 2-3 months. Happens both in KDE and fluxbox.
It is not possible to restart or shut down the computer completely after this has happened. The shut down process starts, but then it just stops with a blinking cursor at the top left corner. Other than this and the keyboard not responding, everything else seems to work these few occasions.
Any ideas?
