I recently purchased a Dell Optiplex 7080 w/ Intel i7-10700. Installed with CentOS 7.9 just fine. I am now unable to change display resolution. Settings shows "Unknown Display". Preliminary investigation shows PCI ID 8086:9bc5 (rev 05) as "UHD Graphics 630" via devicehunt.com.

$ dmesg

snd_hda_codec_hdmi hdaudioC0D2: No i915 binding for Intel HDMI/DP codec
...
Package
xorg-x11-drv-intel-2.99.917-28.20180530.el7.x86_64 is installed.
My understanding is graphics support was added in later versions of the kernel. I'd like to stick with the official CentOS 7.9 kernel. Is there a way to update/backport the driver myself?

It's listed as supported by the i915 driver on CentOS 8 but not on 7. I suspect it will never be added as CentOS/RHEL 7 has gone past the date when they add new hardware support. It _might_ work if you used the ELRepo kernel-ml but I don't know whether it also needs the xorg support too.

Hi @TrevorH
Perhaps in some other way to solve this? (Without switching to CentOS 8)
- Maybe install or compile something?
