I would doubt it's an Xorg issue, as both Debian/Devuan and recent
Ubuntu releases use the same Xorg version. Devuan uses xorg/kernel
packages unmodified from Debian so the versions listed for beowulf and
buster will be identical, across both Devuan and Debian package
information sites.


You didn't mention which version of Ubuntu you tried, but for Xorg
that's irrelevant as the LTS and latest release have the same version
as Debian/Devuan.


Since it works in Ubuntu, it's unlikely to be a BIOS version issue
(although that might make a difference for older kernel versions?).

Most likely, you could try upgrading to the backports version of linux
kernel in Beowulf to see if that makes a difference. Ubuntu recent
releases have a newer kernel version than Devuan Beowulf/Debian Buster
main repository, while the beowulf-backports/buster-backports
repository has a newer kernel than the Ubuntu repository.


The default kernel package on beowulf amd64 is `4.19+105+deb10u9`
while beowulf-backports has `5.10.13-1~bpo10+1`
