How to fix QuickSync not working and /dev/dri directory not exists problem?

Normally, /dev/dri directory not exists is either because Intel driver is not load or not used. 

1. Confirm the intel driver is not used. The last number 0 means the driver is not used.

$ lsmod | grep ^i915

i915                 1274000  0

1. Edit /etc/default/grub. and remove the "nomodeset" option from "GRUB_CMDLINE_LINE" .

$ sed -Ei 's/\s+nomodeset//g' /etc/default/grub

2. update the grub and reboot.

[For CentOS, RHEL, Fedora]

$ grub2-mkconfig -o /boot/grub2/grub.cfg && reboot

[For Ubuntu]

$ update-grub && reboot
