Bug Description

Binary package hint: ubiquity

While installing Herd 5 (Kubuntu X86_64), after partitioning, at about the 70% mark while installing files, my screen went from the X desktop, to a text console (probably pty0, it had the kernel messages on it, with 'Kernel active' at the bottom)
  I waited a minute, and when it didn't restore itself, I hit alt-f7 to get back to X. WHat I got was a black screen with a dialog box saying that the screen was locked, and I am prompted to enter the password for the 'ubuntu' user.
  Hitting enter with the password field blank, or any simple password I guessed (password, user, ubuntu, root, toor) simply said 'unlock failed'.

  Looks like its time to reboot and restart the install... Hope it goes different.

My second attempt to install went without a hitch, as I forced myself to
sit on my hands and not explore the LiveCD system while ubiquity was
busy...

I suspect it ran out of memory, but reassigning to xorg-server in case it's some other kind of X crash ...

"I suspect it ran out of memory" do you think because of a leak? (I have 1gb ram and 256mb gfx ram)

Actually, I wasn't able to get this to repeat. It occurred on an AMD64
with 512MB RAM as I was exploring the K menu (not actually opening any
apps) while ubiquity was doing the initial load. The system didn't crash
- just the screen went blank. I could see the hdd light blinking, so the
file load was still continuing in the background. When I stroke the
touchpad, or press a key, the normal 'unlock screen' dialog opens up. The
problem is that there's no password for the 'ubuntu' user, so I didn't
know how to unlock it again.
   When I started over, and sat on my hands during the load, it worked
fine, so there's the possibility that I somehow fat-fingered some hotkey
to lock the screen.
   Is there such a hotkey defined in the X config of the LiveCD?
   If so, is it recoverable? Since there's no password defined for the
'ubuntu' user that is active in a liveCD session, how would one unlock the
screen in that case?
