I cannot use dead keys any more after upgrading from Mandrake 10.0 to
Mandriva, and from kde 3.2 to 3.3. I played with the keyboard configuration
utility (Xkb options), tried Menu, right Alt and right Windows. No success.
The Italian keyboard, for all the rest, works well.
The setxkbmap is called as follows:

setxkbmap -model pc104 -layout it -variant basic
setxkbmap -option compose:menu,altwin:meta_super

Sorry to bother with this rather stupid problem, and thanks for any help.
