This is not strictly a debian question, as I had this same problem
under redhat 7 before I switched to Sarge.
There is some odd key combination that changes the way my keyboard
behaves. I've noticed two distinct modes that it seems to get locked
into:
1) Totally Insane Capslock. My capslock light will be OFF, but it
reacts not as if it's on, but as if it's now a SHIFTLOCK and on. All
of my alpha characters are IN UPPERCASE and all of my numericals are
now symbols. It seems as if ctrl-leftshift will *sometimes* get out
of this mode, but that doesn't appear to be what activates it (and I
have no idea what does!)
2) Sticky-Ctl-Alt. This is a pretty nasty one. It's hard to tell
it's activated, but it's as if I'm holding down both the ctrl and alt
keys. I made this mistake of pressing backspace without realizing
this was on and lost my entire x session.
Does this sound familiar to anyone? Have I activated some sort of
accessability features or is my keyboard just horked? I've tried
doing some googling for this, but haven't really been all that
successful. I don't have a programmable keyboard, I can't imagine
that it's that.
Any ideas would be appreciated.
