I am not sure if this is a bug or a feature of Mint 12. That's why I am posting it here.
I have 4 PCs running Mint 12 (Linux 3.0.0-12-generic #20-Ubuntu SMP x86_64 x86_64 x86_64 GNU/Linux) and I use 2 keyboard layouts: US and Greek. I noticed that I can login to my desktop using both layouts for my password. This is not the same when I am asked for the sudo password, to run the system updates for example, where only the US layout is working (the correct for my password).
bug or feature
