A recently reported symmetry breaking of density profiles of fluid argonconfined by two parallel solid walls of carbon dioxide is studied. Thecalculations are performed in the framework of a nonlocal density functionaltheory. It is shown that the existence of such asymmetrical solutions isrestricted to a special choice for the adsorption potential, where theattraction of the solid-fluid interaction is reduced by the introduction of ahard-wall repulsion. The behavior as a function of the slit's width is alsodiscussed. All the results are placed in the context of the current knowledgeon this matter.
