I was experiencing this bug with KDE NEON 5.8 on my MacBookPro5,5. Luckily I stumbled over https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-340/+bug/1389215/comments/50 (Thank you Hans Deragon (deragon)).
As my laptop uses NVIDIA GeForce 9400M, I had to slightly tweak his script and like magic after making it executable, running it and a quick reboot for safe measures.. IT WORKS!!
