Yes, you're right! When I wiggle the mouse the wait ends sooner.
Indeed, if I don't move the mouse at all and don't press any key the
screen just stays blank (I waited approx. 5 minutes and it still was
black).
I attached the output of dmesg | grep "random". As you can see, "crng
init done" appears after the 5 minutes I waited.
Yes, this seems to confirm my suspicion that something is blocking by
calling getrandom without GRND_NONBLOCK.
Since there is no "splash" in my kernel command line in grub, I added
"noplymouth" to it, but that didn't help. Maybe it's another package
that calls getrandom without GRND_NONBLOCK. Let me know if I can
support the investigation somehow.
The situation you describe does not implicate plymouth, because the
pause occurs after you enter your credentials. This is a tricky one,
because it could be lightdm, or systemd which is a known offender,
xorg, or anything else in your session. This is a tricky problem to
diagnose because, as soon as you start typing, your login will
complete. I suggest reporting this against lightdm to get maintainer
advice. The Debian Xfce and lightdm maintainer has commented on
#897572 and is aware of the getrandom issue, but I could not find any
lightdm issue for it.
Which iso image did you use to install testing?
Kind regards,
Seems like there is a related lightdm issue:
https://github.com/CanonicalLtd/lightdm/issues/17
I added a comment pointing to the #897572 bug report. In addition, I
also installed GDM to see whether the same problem occurs. Indeed, not
even the login screen is shown before I have pressed some keys.
To install testing I used the latest weekly build of the netinstaller
with non-free firmware (firmware-testing-amd64-netinst.iso).
Best regards,
Dino
