Unusual keyboard issue
I'm running Etch with a standard laptop install. I normally use KDE desktop, yesterday I noticed my "c" key stopped working in KDE. For troubleshooting I tried my windoze hard drive which it works fine in. It also works in KDM and also Gnome, which I'm writing this from. I tried an apt-get dist-upgrade last night with no help. I've look in KDE for the keyboard setting but haven't found anything. I've also tried an apt-get install xserver-xorg-key* hoping to find a keyboard map but that didn't produce anything.
Does anybody have any ideas as to where to go next?
