You can download Electrum, and once launched it will prompt you to either create a "Standard" or "Segwit" wallet, choose segwit, and voila, there you have it.

What do I need to do?

Other then generating the wallet, nothing.

Segwit2x was a controversial planned hard fork that didn't come to fruition because of lack of support. It aimed to combine Segwit with a block size increase. There was another Segwit2x project that was launched recently if I remember correctly, but it has nothing to do with the original. Neither of them has anything to do with Bitcoin.
