I have this problem after an upgrade from 9.04 to 9.10. With 9.04, the
boot was interrupted and resumed again after I entered the passphrase
After upgrade to 9.10, the passphrase prompt appears and immediately the
graphical login screen appears. I switch back with ALT+CTRL+F1, but no
keystrokes
Yes that helps.
Thank you for the explanation.

Patrick J. LoPresti and mish,
thank you both for the help.
indeed /dev/random is the problem. Like mish said i could use
/dev/urandom. I don't have /dev/hwrandom, so the urandom solution or the
script mentioned in the manpage of random is the one i need.
As a theoretically question, how can i
What version of Ubuntu are you using?
On mine (7.10 aka. Gutsy), /etc/init.d/urandom already propagates the
random seed across reboots in /var/lib/urandom/random-seed.
This should make /dev/urandom very safe to use, assuming that file
itself is never compromised.

I use 7.10 but i didn't know that urandom saves the random seed during
start, restart and shutdown.
Everywhere on the net there can be read that urandom is not as secure as
random is. but i am a bit confused now. how could it be that urandom is
not as secure as random if uradom just saves the
It's a long story that depends on how you define random and
secure. And this is really the wrong forum for this question and
answer. But I'll give it a whack anyway. :-)
/dev/random never hands out more bits than it has entropy available.
(It collects entropy from the timings of keyboard
I have to say that this bug is not completely solved.
Some problems still exist. this is what i experience.
Using gutsy, up-to-date as of 08.03.2008
Encrypted partitions: home and swap
Type of encryption: Luks
crypttab:
home /dev/sda3 none luks,retry=1,cipher=aes-lrw-benbi
swap /dev/sda4
Well it seems that is is a problem with the encrypted swap.
i changed the lines in fstab and crypttab this way:
fstab:
/dev/mapper/swap noneswapsw 0 0
/dev/mapper/home /home ext3defaults0 0
crypttab:
swap /dev/sda4 /dev/random swap
home
/dev/random blocks until it has enough entropy to guarantee
randomness. That is probably why wiggling the touchpad gets things
going again.
If you have /dev/hwrandom, you can use that... Otherwise, you can use
/dev/urandom to avoid blocking, but theoretically this could give up
some security
I think your problem is related to using /dev/random in your crypttab
swap /dev/sda4 /dev/random swap
/dev/random collects entropy from different parts of the system
(including mouse/touchpad usage). I'm not sure, but I suspect entropy
is not saved at shutdown, so entropy must be collected

Due to the lack of responses that anyone can still confirm that the
described problem still appears, and the recent feedback that an
unrelated issue has been solved (thanks faithful for reporting back), I
come to the conclusion that this bug has been fixed some time ago. I
cannot really reproduce
Ok my problem is resolved. Recent updates solved it.

no it doesn't. You are reenabling password input in usplash, which isn't a good
idea with current usplash
(try switching virtual consoles when entering your password to find out why)

Reinhard, correct me if I'm wrong but isn't the init.d call to

Using feisty with cryptsetup 2:1.0.4+svn26-1ubuntu1 I still don't get a proper
password prompt. Usplash is terminated correctly but the console isn't
switched. If I switch it manually, I can't enter the password anymore. (I can
write but all I write is shown in plain text).
Which means I have
today i spent a whole 10hours on updating from dapper to edgy. Most of
the time i spent while trying to debug the latest cryptsetup-package i

bug rely on
cryptsetup (2:1.0.4-8ubuntu2) feisty; urgency=low

* fix and improve initramfs hook: terminate usplash if running, since
adequate secure text input is not possible with usplash ATM
* usplash support: Terminate usplash before asking a password.

I 'fixed' (since stty -echo didn't work) the password echo problem using
this trick:

for the password being printed plain text to the console it seems to

Hi,
when I tried Marc`s patch for edgy, I stumbled across a major security issue.
