Not really.  Nothing looks out of the ordinary on your log.  As for the
symptoms, when you say black screen, do you mean the screen blanks like
flickers or the signal to the monitor goes away or like someone has colored the
desktop black?  Please check that the display cable is not loose where it
connects to the monitor and the graphics card.
