Same problem as encountered with Mint 9 (see viewtopic.php?f=10&t=342), save that the solution does not seem to work with Mint 11.

It is about a keyboard with a swiss-french layout. All keys seem to work except for the “@“, which was originally (= under Mac OS) obtained with alt-g.
does not seem to work anymore.

Any idea how i can solve this?

edit: duh, it works when logged as root. Still, none of the configurations listed under "apple" or apple "laptop" seem to work...
