can't recognize the graphics card of i5-7200U

[charse]

Hi ,My compute CPU is Intel i5-7200U , Built-in graphics is intel HD graphics 620 ;
Test Step:
1. the version :gvt-stable-4.14 , gvt-stable-4.17 , GVT-g-18q1.iso ;They can't recognize the graphics card.
   lspci show "Intel Corporation Device 5916";
   
2. I test the Fedora 28 , kernel version: 4.16; It can recognize the graphics card;


 Why the gvt version can't recognize the graphics card. 
 What should I do?  Thanks!
 Best Regards!
