user32730: I have an external drive where at some point I did a complete backup of my (linux) home directory.
There's a directory .bitcoin.
I now have a computer, and I just installed bitcoin-qt and other stuff. I started it and it generated a new receiver address.
If I copy the old .bitcoin directory from the external drive to my current new home, will it work?

user30396: To avoid any problem,in your source computer backup your private keys 
bitcoind dumpprivkey 
to answer your question, By default Bitcoin will put its data here:
~/.bitcoin/
I think the wallet is located in a file wallet.dat(https://en.bitcoin.it/wiki/Data_directory#Linux), so if you copy it, it will works.
fore a best security level, encrypt your wallet with a paraphrase before backaping it.
