Comment 11 for bug 90687

Percy, your suggestions don't work for me (Ubuntu Hardy Heron on Acer Aspire 5920).
About the acrace, euro and dollar keys, I tested all you sayd in 30-keymap-acer.fdi, and then I rebooted, but nothing happened. To say the truth in the default file of my Hadry there already is the entry related to euro and dollar keys
        <append key="input.keymap.data" type="strlist">e033:euro</append> <!-- Euro symbol -->
        <append key="input.keymap.data" type="strlist">e034:dollar</append> <!-- Dollar symbol -->

but they don't work. Is there a way to debug the key mapping?

About the multimedia keys, I created the ~/.xbindkeysrc as you suggested. I downloaded xbindkeys package and the I added it to gnome session startup, but nothing happened at the X restart. I made a debug of xbindkeys launching it from command line:

displayName = :0.0
rc file = /home/marco/.xbindkeysrc
rc guile file = /home/marco/.xbindkeysrc.scm
getting rc guile file /home/marco/.xbindkeysrc.scm.
