[Bug 1442405] Re: plymouth locks console termios, breaking serial consoles
Correction: I didn't have lightdm, but I still had lightdm.conf. I did
aptitude purge lightdm, and now everything's okay.
This seems really fragile to me.

Title:
plymouth locks console termios, breaking serial consoles
Status in plymouth package in Ubuntu:
Incomplete
Status in upstart package in Ubuntu:
Invalid
Bug description:
I have a more or less standard non-graphical Ubuntu 14.04 server
installation. I boot with console=ttyS1,115200, and I have
/etc/init/ttyS1.conf that's more or less the same as all the standard
/etc/init/ttyN.conf files.
The serial console login doesn't work because plymouth seems to think
it's showing its bootsplash and it locks the termios settings using
TIOCSLCKTRMIOS. This completely breaks /bin/login, which *requires*
working buffered mode.
I have no idea what mechanism is supposed to tell Plymouth to dismiss
its splash screen when boot up is done, but it's clearly broken. What
gives?
