It is known that some orbits in the principal planes of a triaxial potential well are unstable to oscillations perpendicular to those planes. This fact suggests that if a galaxy has a central bar or a triaxial unseen halo, the disc may become warped. Here, the response of a massive galactic disc to a variety of imposed triaxial forcing potentials is investigated, using both numerical experiment and analytic methods. Galactic bars are unlikely to be responsible for warps. A halo of constant shape, flat rotation curve and reasonable mass, with a figure rotating retrograde to the disc, can amplify a small disturbance to an observable level within reasonable times, if it is strongly flattened towards the disc, and weakly barred.
