Krzysztof, you should be using 3.13.0-39 patched by me (the newer version is the vanilla Ubuntu kernel which does not support MST).
Regarding your question about cables: you should not worry about that. According to [1]: > Despite what you may read, there is no such thing as a > DisplayPort 1.1 cable and DisplayPort 1.2 cable.

So basically any DP cable should be ok. If you have the intel drivers and the correct kernel up and running nothing else is required to get a working multi-display setup.
