Dear Maintainer,

Upgrade from Debian 11 desktop with little customisation. Debian 11 was up to
date
- standard changes to sources.list
- apt update
- apt upgrade

After installing all new packages and rebooting, no GUI at all
X server not running
missing xorg.conf

NOTE that running X -configure gave "error 2", though little (I can see) in log
to  indicate such an issue.
I assume the error prevented the new conf from being used
