unfortunately can't take screen shot of cursor issue in simplest terms when move mouse 3rd monitor changes pointer black "x" white outline.

i have tried changing driver versions , handful of other things nothing seems work, have feeling i'm missing simple.

i have played around xorg.conf file bit keep breaking things in there , having revert let nvidia-xconfig deal file me.

here relevant system specs:

• gpu: 2x gtx 580 classified lc
• current driver version: nvidia 364.19 (i have tried 367, 370, , 361 drivers). standard x.org x server driver causes cursor lag issues works 3 monitors.
