then take a good look at pokens guid i linked to above. originally it looked like you where having issues loading graphics if i recall so maybe look into what your laptop uses for that. I'm not sure if the 6510 uses sandy core graphics hd3000 or another gpu. but i do see posts for the 6x10 (x can be 2,4,5) which might be in the same family off hand i do not know as the newest dell laptop i own is the old d630 with nvidia. which unfortunately just sits around collecting dust for now. last time i booted it i think was for yosemite DP1
