As Pugachev Cobra said above, the Ailerons are conventional cable/PCU control. Rudder, Elevators and spoilers are FBW. Flaps/slats are electric.
The FBW computers can be deselected and the aircraft can still be flown with certain features disabled (tail strike protection stall protection etc)
If all three hydraulic systems are lost then control is reduced to stab trim and engine thrust.
