My experience with -37 was not of /no/ text, but of a "random"
character all over the screen. As I described, the VCs could
be used even though you couldn't read the output from commands.
(Changing font size would change the character.)

But when I upgraded to -38 on 2026-02-12, normality was restored.
On my systems, -37 is long gone (2026-03-13), and all versions
before and since -37 have worked normally.

That's never been my experience, and you make it sound as if
the system is unusable. Is that the case? My keyboard was never
affected. I'm writing this on a bullseye, old-old system,
up to date with -42.

The one oddity that I do see, and this is older than bullseye
and still occurs on bookworm/trixie, is something that I think
I reported many years ago but haven't been worried about. It
happens on different computers too.

While not logged in (ie on the initial getty), the login:
prompt may be erased by what appears to be a self generated
Home ClearLine sequence. This can also happen at the
Passphrase: prompt when I unlock /home (logged in as the
dedicated "unlock" user, who immediately gets logged out
by its ~/.profile script). As I then login as me, and
startx, I don't have the opportunity to see whether tty1
would keep behaving like this if I kept logging out/in.
Nor have I ever seen this behaviour on the other ttys,
but that could be because the number of opportunities is
just too low (very occasional usage).

Cheers,
David.
