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.

Hmmm looking at the kernel modules they should be in a directory like:

/lib/modules/4.18.0-147.0.3.el8_1.x86_64/kernel/drivers/gpu/drm/i915/gvt/kvmgt.ko.xz /lib/modules/4.18.0-147.0.3.el8_1.x86_64/kernel/drivers/gpu/drm/i915/i915.ko.xz /lib/modules/4.18.0-147.3.1.el8_1.x86_64/kernel/drivers/gpu/drm/i915/gvt/kvmgt.ko.xz /lib/modules/4.18.0-147.3.1.el8_1.x86_64/kernel/drivers/gpu/drm/i915/i915.ko.xz /lib/modules/4.18.0-147.el8.x86_64/kernel/drivers/gpu/drm/i915/gvt/kvmgt.ko.xz /lib/modules/4.18.0-147.el8.x86_64/kernel/drivers/gpu/drm/i915/i915.ko.xz

see if they exist on your system and if they do try an insmod with the kernel you are using. If that works then it is a matter of figuring out why its not finding the modules. If it doesn't exist.. it is a matter of finding out why

Thanks here is the kernel I'm running on C8 and the files listing.

insmod i915 and insmod i915.ko both say no file found.

modprobe i915 does work. that is weird.

Whats the output of "cat /proc/cmdline" ...

Mmmh, are you using a dual graphics platform?

Just a wild guess; substitute your grub config part

blacklist=nouveau nomodeset nouveau.modeset=0

with

module_blacklist=nouveau,amdgpu,radeon i915.alpha_support=1

Install the new grub config and rebuild your init ramdisk, just for consistency ...

ok I did that - regen that file and verified with cat /proc/cmdline This is not a dual monitor situation. I also removed all that other "legacy" stuff I had in there.

Those settings aren't typically for a dual-monitor setup specifically, but for enabling the 3rd-party NVidia or AMD drivers, instead of the open source, in-kernel drivers.

If you are only using an intel GPU, you don't need them.
