Hello, I have an Intel NUC7i3 with 620 graphics and an Intel NUC7i7 with 640 graphics. I have loaded CentOS 6.9 and the graphics is not fully working. I believe that I need a driver. Does CentOS support the Intel 620 and 640 graphics and if not, can someone please point me in the direction of the drivers, with install instructions. Regards, Mark Woolfson
