A captain reports about his refusal of a B757-200 aircraft during pre-departure planning after inbound write-ups for an idg light flashing on and off; followed by failure of the first officer's FD; than internal airspeed bug; then green arc on navigation display and finally electrical smell with smoke in the cockpit. Maintenance supervisor did not want to address the smoke event.

Narrative:
Aircraft to which (we were) assigned; arrived at gate in ZZZ with write-ups concerning idg light flashing on and off followed by failure of first officer's position flight director (FD); then internal airspeed bug; then green arc on navigation display and finally an electrical smell with smoke in the cockpit. This could be assumed to be a cascading system failure. ZZZ mechanics assigned to flight informed me they had been told to defer everything and get the aircraft out of town. Smoke event was not even to be addressed. I refused the aircraft which resulted in nothing less than just a plain old fashioned hissy fit on the part of the maintenance supervisor. Upon checking maintenance status of aircraft 2 days later; discovered the plane was grounded for 37 hours; returned to line and then returned to blocks on first flight; then given a 1.5 hour test flight with yet another notation of smoke in the cockpit. Issue with this report is ZZZ maintenance supervisors; not line mechanics; trying to release back to the line unsafe aircraft at any cost.
