Wanted - pointers re where to look for keyboard bug.

[Nigel Cunningham]

Hi all.

I have the intermittent problem with some keys stopping working in KDE and 
Gnome (I guess in general), even though events continue to be reported in 
xev. Would someone please give me a pointer or two as to how I could go about 
debugging this? I'm running xorg from git, and can use gdb from over LAN to 
debug if I know what to look for. Patching and recompiling is no problem.

Regards,

Nigel
