So there's no _XKB_RULES_NAMES property set which is what QEMU
wants to see.

The  XKEYBOARD extension is missing which is why we dont' see the
XKB property above.

We have a heuristic that tries to deal with this by checking what
keycode  "XK_Page_Up" maps to, but that has failed for you too.

So I'm puzzlled what key map this X server is actually using.


I don't have SLackware handy, but can't reproduce on Fedora with
TigerVNC.

Daniel
