numeric keypad craziness

[Mike Wright]

Hi all,

I have a bunch of Xen VMs running an assortment of Fedora versions and I 
connect to each of them via VNC.  Each occupies an individual workspace 
in Domain-0.  Everybody shares the keyboard and mouse.  Works great.

However, on one VM the 10-key part of the keyboard, when NumLock is on, 
doesn't work correctly.  The behavior is different depending upon 
whether it is in single keypress mode or whether it has gone into 
auto-repeat mode, where it behaves correctly.

The craziness starts in single key press mode where there are various 
behaviors depending on whether it is typing into a console, an xterm, or 
a GUI window, such as this Thunderbird, and whether it is an arrow key 
or one of the named keys (Ins, Del, Home, End, PgUp, PgDn).

In all cases the named keys perform their non-NumLock action.  In GUI 
apps and the consoles the arrow keys perform their arrow action but in 
an xterm the arrow keys type a letter: 8->A, 2->B, 6->C, 4->D.

This survives reboots (the whole system) and restarts (just this VM).

For the record, each VM keyboard is set to Generic 105 key international 
layout and the NumLock key is on.

I know almost nothing about how the keyboard subsystem works.  Anybody 
have any idea where to go from here?

Thanks,
Mike Wright
