No, there is no hard requirement for this, unfortunately, this error
loading the intel driver module properly hence a target machine ends up
incorrect resolution. The idea is to avoid this error so that loading of
intel module (for Intel HD 630) works fine.
In a previous version of BR, the combination of intel drivers and xorg
works fine, however, in a new BR release, the combination is broken and
I end up with the error above. So far, I've found that the intel video
driver version is same for both xorg 1.20.xx and 1.21.2 (or 21.1.2).
I'm trying to pinpoint what's been changed in 21.1.x that causes
error but so far I've had no luck.

I tried --enable-kms-only(the other flag is already enabled) but no
Could you please point me to the repo link. The last version on xorg's
seems to be 2.99.917. Perhaps, I'm looking at an old link?

I think, I came across LFS and found some information regarding intel
video driver useful.
In my case, modesetting don't guess the resolution correctly, and intel
driver does the job.
