kde4 looses keyboard

Hi all,

I have the problem that I lose the keyboard in KDE 4 every now and then. This happened to me yesterday and just now. None of the keys and combinations I tried did anything. I was not able to switch to the terminal, Alt-Tab did not work, killing X with Ctrl-Alt-Back had no effect. Iam sure the keyboard itself is OK, the KVM switch did react on Ctrl-ctrl and on the other PC, the keyboard worked as expected. Also, the kernel logged some unassigned key codes. I did not see any thing special in the system or X logs.

The only way to fix this was to ssh into the PC and restart X.

I don't know about the first time but the second time I was in System settings --> Keyboard & Mouse --> Keyboard Shortcuts when the keyboard stopped working. I tried to reproduce this problem but my first attempts failed. Who knows how to debug such a situation?

Thanks, Theo

RE: kde4 looses keyboard

I have the same problem. It happens very often. Sometime the keyboard doesn't work immediately after startup, sometimes it stops while i do something (e.g. after appearing run command dialog).

Mouse did it too, but only once.

The only way to fix is restart X server.

I have this problem using synergy and kde4 together. Sometimes the keyboard just dies -- not only via synergy but when I go straight to the synergy client's keyboard.

You still have copy and paste though, so I was able to run xev. Once I did that and pressed a few keys it kicked it back into shape. Like knocking a TV on the side to get the picture back I guess. This is KDE 4.1.1 on Kubuntu 8.04 Smelly Satyr or whatever.

I've had a similar problem. The keyboard would not work everytime I logged in. I found i need to remove the following lines in .kde/share/config/kaccessrc

Source code

4

[Keyboard]
GestureConfirmation=true
Gestures=true
SlowKeys=true


This made the keyboard work again.
