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.

to
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.

Google gave me <https://wiki.debian.org/InstallingDebianOn/Dell/Inspiron%2014%203000%20%283493%29/buster>.

It says:
This requires a later kernel than 4.19.0 (that comes with buster)
to work. THe system will boot but xorg will not find any usable
displays. The 5.5.0 amd64 kernel from buster-backports does work if
the buster-backports version of wireless-regdb is also installed. Also
the following lines should be added to /etc/environment:
LIBVA_DRIVERS_PATH=/usr/lib/x86_64-linux-gnu/dri LIBVA_DRIVER_NAME=iHD
I can't vouch for any of this, especially the last part.
