[Bug 692170] Re: numlock weirdness when typing passphrase

[Lamer]

I have seen the same behavior you describe on my ubuntu 10.04, whenever
I forgot to activate Num Lock key. It is quite annoying, but you can use
Home key (if I remember it correctly) to return back to plymouth boot
screen.

What I think is a lot worse is that there seem to be no way I know of (without recompiling your own kernel; numlockx or setleds and similar solutions are useless if you need Num Lock enabled during cryptsetup) to force Linux to respect BIOS setting saying Num Lock should be enabled on boot. For details see:
http://lkml.indiana.edu/hypermail/linux/kernel/0702.1/2363.html
http://lkml.indiana.edu/hypermail/linux/kernel/0707.1/1834.html
etc. (search the web for more:)

I would even try to compile my own kernel, but it would probably mean
recompiling it for each security patch again, which I consider way too
much effort compared to just pushing one more key during each bootup.
Still I think some widely used distro like Ubuntu or Linux Mint could
perhaps provide modified kernel solving this endless Num Lock problem,
because if Windows can why not Linux?

Title:
  numlock weirdness when typing passphrase

Status in “cryptsetup” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: cryptsetup

  I'm running an encrypted setup and I've noticed a bug since Ubuntu
  10.04 or so (running 10.10 now), if not earlier. Whenever I start
  inputting my passphrase and I type a digit without Num Lock enabled,
  Ubuntu takes me to the console, displaying the Enter passphrase dialog
  on a new line for each typed character, never returning to the new
  fancy plymouth boot screen.
