There is no version of X that works on CentOS. What is there is incomplete from what I can tell. In part I believe that is due to bugs in the upstream drivers if I understand Jim Perrin correctly. I spent days trying to get X and gave up. I tried using a version of Fedora with Mate which worked but was buggy. As much as I didn't want to do it, I ended up using the latest version of Raspbian which comes with Pixel and works great. I had other reasons such as the newest Raspbian makes it easy to switch the PI3 serial port behavior back to what is was for the PI2. Important if you wish to use one of the GPS hats.
