Bart-Williams made 28 appearances for Ipswich last season after moving to Suffolk from Charlton Athletic.
His final appearance for Ipswich was in the play-off semi-final first leg against West Ham.
Bart-Williams was released by Town boss Joe Royle later the same month and Leeds could become the sixth club of his career.
Kevin Blackwell wants midfield cover with Eirik Bakke ruled out for the season and Seth Johnson out until January. Also, Jermaine Wright is fighting to be fit for the Derby opener on August 7.
Trialists Tomas Rsaza, Craig Hignett, Steve Guppy and Rami Shaaban should also start tonight.
