Chess Interface for Ubuntu Linux

Hi.

I am discovering the Live Chess on Chess.com community playing 5 minute type chess as I have for many years on ICC and FICS in the past.   Being such a veteran, I understand the importance of timeseal and playing 5 minute online chess via a downloaded chess interface as opposed to through a browser.  I currently have the applications eboard, knights, and xboard installed on my computer.  I can connect to FICS using eboard, but I have not figured out how to instead connect to the Chess.com server.  Is this possible?  How do I configure my chess interface(s) or what interface should I install (NOTE-- I am NOT running Microsoft Windows or MacIntosh as I have mentioned -- I run Linux/Unix (Ubuntu)).

Thank anyone in advance for any help. 

Chess.com's live chess is browser-based only.

Its not an ICC interface but the open source ChessX chess database program can be compiled on Linux.
