I`m running Xubuntu 12.10, Ubuntu 12.10 and Linux Mint 14 in VirtualBox 4.10 with Windows 7 as the host system. My keyboard is a Logitech G110 with a Norwegian layout, and I have configured the host system accordingly.
In all my virtual linux machines I am unable to type the @-symbol and the tilde (~) symbol. These are suppose to be mapped to AltGr+2 and AltGr+^ respectively (this would be different on US keyboards). Still, the British pound symbol and the American $ mapped to AltGr+3 and AltGr+4 respectively work fine.
I have tried adding an .Xmodmap-file with the line
keycode 113 = Mode_switch Multi_key
as suggested by some to fix an issue with AltGr not working at all, but with no result. Any help would be greatly appreciated!
