We investigate the exact dynamics of trace distance discord by considering two qubits under dephasing whose states belong to a class of Xš¯‘‹Xitalic_X states beyond Bell diagonal form. The necessary condition for the occurrence of freezing trace distance discord is found and compared with that of entropic discord. For an illustration, we consider two interacting qubits coupled to independent reservoirs and demonstrate these dynamical properties of trace distan
