Same problem...NO LUCK on Satellite 1415
Ok, I've found plentty of possible fixes that don't work. This seems to be the closest to what I am experiancing with the same hardware. (Satellite 1415 and 1410 are same except for initial OS from factory.)
It seems that atleast on of the persons on this thread has had some luck. Would it be possible to post your XF86Config? Or atleast email me at thewag_at_wagners.homeip.net?
