Narrative:
100 NM north of ZZZ deviating west to avoid trw area. Right CSD drive light illuminated; accomplished right gen drive QRH procedure used captain's emergency authority to attempt to start placarded APU: unable. Single gen ops. Determined that ZZZ was VFR and nearest suitable airport. Landed at ZZZ. Note 1: this is my second CSD failure with inoperative APU in 8 months; may signal a trend. Note 2: trip was my first flight with new display. Due to fatigue and limited familiarity and lack of proficient instrument scan while executing visual approach flew lower than optimum descent path. Lack of actual experience with new display late at night was a human factors issue.
