I know the workaround with @-key problems between linux and windows. I think I have a different problem.
I use Ubuntu 9.10 as virtualbox guest on a windows 7 host (synergy client). My Ubuntu 9.04 notebook is the synergy server. With the xmodmap lines the @ key is working well with windows 7. But in the virtualbox guest (Ubuntu 9.10) it won't work. How can I solve this issue?
The locale of both linux systems is de_DE.UTF-8
