20 Yes and No,
22 I had similar problems but completely deterministic.
23 When the keyboard is handled by hal it produces different keycodes then
24 before.
26 In my case the PgDn key now generates a code which was previously
27 generated by the key right to the right Windows key.
28 And in my .Xmodmap I had this code defined as Mode_switch which
29 made the key "dead" in my editor.
30 Try using xev to see which codes are generated by the keys which
31 cause you problems. Then look at all places where X11 key codes are
32 redefined i.e. xmodmap is called.
