Narrative:

We were dispatched with MEL 22-30-01 auto thrust system inoperative. On descent we noticed #2 eng thrust lever disagree ECAM message flickering on and off. We also noticed the #2 engine N1 indication fluctuate from 30-51% N1. We initially thought this was associated with the auto thrust inoperative MEL item. As we approached 10000ft MSL the N1 stayed about 32% and N2 about 65%. As the first officer brought thrust levers up on both engines we noticed some aircraft yaw. Engine #1 was operating normally. We moved the #2 thrust lever from idle to full climb power with no response on the engine indications and no thrust or yawing of the aircraft as we moved the #2 thrust lever. The engine seemed to have failed and was wind milling. Oil pressure was normal; yet we had no control of the engine with the thrust lever; there were no other ECAM indications. There were no vibrations or fire or overheat indications. To avoid thrust lever problems; and since it appeared we had lost all thrust and throttle control of the #2 engine; I ran the engine #2 failure checklist in the QRH. This was about 2000ft AGL. We completed the engine failure and landing checklists and landed without incident. We taxied to the gate and completed our after landing and shutdown checklists and called maintenance to report the malfunction. There was little time (last 3-4 min of flight) to do much coordination as this happened shortly before landing.

Title: After being dispatched with autothrust deferred; an A320 crew discovered during descent that the number two engine was not responding to thrust lever movement. Crew continued and landed without further incident.
