Thanks for the explanation.

I'm quite sure I did not fiddled with nvidia-alternative before the
system malfunction (I'm quite sure I did not at all ever). I could have
done it trying to recover the situation, reconfiguring related
packages. So, I cannot explain what rendered my Xorg server unusable.

That said, is this to be still considered a bug or it is only a problem
local to my installation? In the latter case, excuse me for the noise
and feel free to close the bug (or lower the importance: I don't want
to block the migration to testing without a valid reason).
