I have a problem running the drivers for my Nvidia,I found the online tutorial on this page wheresmykeyboard.com and step by step I used the instructions contained therein.
First error i got after command lsmod | grep -i ‘vga_switcheroo’ I ignored it and went further,
I ran ./Downloads/cuda_7.5.18linux.run --override compiler and this is what I got.
