I got a Logitech EX110 wireless keyboard and mouse set about a year or so ago, maybe more. The number pad on the keyboard stopped working after a while, so I complained to Logitech, and they sent me a new keyboard (actually, the whole set).
I've had the problem on and off again a couple of times since then, but it usually only lasts a few days before all is well again.
However, my son also has the same set (well, same model, different pieces of hardware) on his Windows XP machine, and he has _never_ had this problem. Tonight, he suggested that it might be a Linux problem, so I took our spare keyboard of this same type and switched them on my machine.
Surprise: the new keyboard has exactly the same problem - no response from the number pad.
Actually, that's not entirely accurate. The num lock and the Enter key both work, but the 5 key produces some control combination I don't recognize (seems to behave something like ^V of a previously ^X'd clipboard copy, unrelated to the current input), and the + key which seems to produce something like ^V^V, or "highlight the current terminal line" or something, but none of the other keys work at all.
You might want to use the xev program under X11 to see what key codes are being seen by the system. I had to create ~/.Xmodmap to map the numeric keypad on my Microsoft Natural keyboard to always send numbers on Mac OS X 10.4.x otherwise python curses applications don't do the right thing.
