Others have probably already said this, but it’s still an issue and it should be easy to fix:
The live USB starts with an empty password. Great, except that if the machine is allowed to go into sleep mode the re-authentication dialog insists on a non-empty password. If I start an install, walk away, and come back to check for success I can’t do so since I can’t get back to seeing the install-completed screen.
If you go to the power management dialog, there’s a checkbox for “Manually block sleep and screen locking.” IF the person doing the install understands this problem, they can flip that switch before starting the install. But someone installing for the first time is unlikely realize that there will be a problem, and unlikely to realize what the problem is; they will just know that the system locks them out and doesn’t let them back in without a reboot.
PLEASE fix this. Any one or combination of the following would work:
- Turn off the default sleep when running in passwordless live mode.
- Perhaps better, have the initialization dialog ask for a non-empty password as well as country and keyboard; you could suggest “ubuntu” as a convenience option.
- Change the re-authentication screen to accept empty password. It IS a legitimate choice.
- Change the installer to turn off sleep until the user acknowledges successful installation. I like this one least because it leaves those who want to actually use the live mode with the same problem: the first sleep means they lose all work in progress.
