For those of us in 5.3 - testing - buster -
Just a heads up to watch your full-upgrades a little more closely when the
https://release.debian.org/transitions/html/xserver1.20.html
transition arrives in a few days probably after the brave folks in sid (unstable) have looked at it.
It will probably not affect many (if at all) but if it does it means using a tty terminal (Ctl-Alt-F1 F2 to F6) and the command line.
I will watch closely as I use Virtualbox for my virtual windoze 7. Note the "collisions" at the bottom of the transitions.html Users on nvidia might have a greater potential for problems than intel gpus.
And a thread from sid users about how it went in sid-unstable.

Hopefully all the bugs are gone before it hits testing. The vast majority of us will have no problems.
peace out
