Hi,
I installed debian buster on minisforum X35G with Core i3-1005G1.
Install went through fine, but lightdm does not start up. Upon
inspecting logs, I found out that X server does not startup for
lightdm to use. Looking /var/log/Xorg.0.log, I see these error messages

Sure enough I cannot find /dev/dri. I double checked and udev is
mounted on /dev

I thought 00:02.0 is the device X is looking for, but for some reason
its equivalent /dev/dri items are missing. Not sure how to help my X.
Please advise.

I added "deb http://deb.debian.org/debian buster-backports main contrib
non-free" to my sources.list and updated/installed 5.10 kernel and
everything is fine per my quick check.
I think 10 generation intel cpu's graphics is not supported in 4.19
kernel that is installed with stable per an article I read while googling.
