CentOS - Mar 2020 - Support for Intel Graphics 605 UHD

I found this site
https://www.linux-hardware.org/index.php?id=pci:8086-3185-8086-2212
Says the Intel UHD 605 graphics chip is supported in kernel > 4.11

centos 8 comes with 4.18 but I am not getting X on CentOS 8 with this chip.

When I put this:
Section "Device"
  Identifier  "Intel Graphics"
  Driver      "intel"
EndSection

in /etc/X11/xorg.conf.d it does not boot into X, when I remove it - it
boots into X with generic driver - not the Intel driver.

Thoughts ?

Ok - I went back to CentOS 7. In the same box.
CentOS 7 has this same file:
Section "Device"
  Identifier  "Intel Graphics"
  Driver      "intel"
EndSection

/var/log/Xorg.0.log has the Driver being Intel i915 version 1.6.0


but in CentOS 8 - it does not work and uses the generic driver.

Thoughts?

1. What does lspci say you have (in EL7 and EL8)
2. What does the kernel say in journalctl or /var/log/messages with respect
to what is detected
3. Do you have xorg-x11-drv-intel and/or intel-gpu-tools installed

In C8 /var/log/messages I see messages about "no i915.ko binding for Intel
codec".

Yes xorg-x11-drv-intel is loaded on C8 and C7.
