Found the problem
kbd -l then kbd -s
please explain clearly whats your problem
I think he did, and the solution too ...
The problem was that the KVM was using a UK format instead of the US format which was causing the @ and a few others to display incorrectly after running the kbd - it showed it was set to 33 so I ran kbd -s and set it to 32 and that worked for me
I assume you rebooted for the settings to be taken into account. A fastest way is to run the "loadkeys" command from the console.
