[arch-general] Keyboad in KDE locks up

Hello, Every once in a while -- not too frequently to be unusable, but certainly enough to be annoying -- the keyboard in KDE will simply lock up. Mouse will still work fine, and keyboard inputs that don't go through KDE -- switching to virtual terminals, resetting X via <ctrl>-<alt>-backspace still work (and, indeed, resetting X and logging back in is the only thing that fixes it). I can't see any real pattern as to when this happens -- programs that I basically always have running, though, are Pidgin, Firefox and keytouchd, as well as, obviously, plasma, etc. I am running the vanilla KDE 4.2 packages. Thanks in advance. This is really starting to become annoying. -- Leonid Grinberg
