Disinterested can mean the same thing, and can be used in the same sentence: He seemed disinterested in our problems, so we stopped asking him for help. However, this is not the most common meaning of disinterested. More often, disinterested is used to mean impartial, or not influenced by personal feelings, opinions, or concerns, as in this example: A disinterested third party resolved the dispute. In addition, some teachers and writers object to the other use of disinterested (not wanting to learn more...) and even view it as an error. Therefore, in formal writing it's best to use disinterested to mean impartial, and uninterested to mean not wanting to learn more or get involved.
A disinterested witness is one who has no interest in the case at bar, or matter in issue, and is legally competent to give testimony. See: dispassionate, equitable, evenhanded, factual, impartial, judicial, just, neutral, objective, open-minded, perfunctory, phlegmatic, torpid, unbiased, unprejudiced.
