That article in turn refers to activity in https://cgit.freedesktop.org/drm-tip, which is the direct rendering manager development site. What I gather from poking around there is that the intel 915 video driver has just been patched to solve the problem I=E2=80=99m hav= ing, but uncertain whether the patch has made it out to the linux distros. The problem affects all intel processors with onboard uhd 630 graphics. I=E2=80=99ve tried gentoo-sources 5.10.27 and 5.11.21. Both have the video problem. I=E2=80=99ve also tried 5.12.4. Can=E2=80=99t get it to boot. H= ave also tried Ubuntu-20.04.2.0-desktop. It works fine on my older intel boxes, but displays the same video problem on my new board/cpu. Haven=E2=80=99t veri= fied it, but guessing none of these have the uhd 630 patch. So, my previous suspects - secure boot, motherboard, grub, and my customized kernel configs - are all innocent and working fine. Just have to wait for the patched intel driver to show up in gentoo-sources. Thanks for all the helpful advice I received! Couldn=E2=80=99t have gotten= this far without it.
