Narrative:

Immediately after takeoff rotation; aircraft experienced a major electrical failure. We lost 5 of the 6 dus; so I transferred control to the first officer who had a working display. In addition; we had numerous alerts for many malfunctioning systems. During climbout to 10000 ft; we also experienced a flight control malfunction. Between 7000 ft and 8000 ft while retracting the slats and accelerating from 220 to 250 knots; the aircraft rolled to the left; requiring a 1/2 to 3/4 yoke input to maintain wings level. We leveled off at 10000 ft; tried to determine what was functioning and what wasn't; and [advised ATC]. QRH consulted. Then we were vectored by ATC for an ILS to landing.this aircraft has a long history of electrical malfunctions; including two mels this morning before we took off. Maintenance also fixed a hydraulic leak last night after we brought the aircraft in.
