[Bug 1082742] Re: plymouthd: ply-terminal.c: 611 ply_terminal_open: Assertion `terminal != ((void *)0)' failed.

[Patola]

Just for the sake of it, I got this problem and it had nothing to do with plymouth. It was caused by a 13.04 update which removed /etc/X11/xorg.conf.d along with exynos5.conf. I just had to do this:
- get into ChromeOS shell (Ctrl-Alt-[←])
- log in as chronos, then sudo su -
- make some directory (mkdir /tmp/x) and mount my SDcard root partition on it (mount /dev/mmcbkl1p7 /tmp/x)
- chroot to it (chroot /tmp/x)
- recreate the xorg.conf.d directory: mkdir /etc/X11/xorg.conf.d
- recreate the exynos5.conf file:
cat > /etc/X11/xorg.conf.d/exynos5.conf <<EOZ

- exit from the chroot: exit
- umount the chroot: umount /tmp/x
- reboot to Ubuntu

Title:
  plymouthd: ply-terminal.c: 611 ply_terminal_open: Assertion `terminal
  != ((void *)0)' failed.

Status in “plymouth” package in Ubuntu:
  Confirmed

Bug description:
  Plymouth on Chromebook always ends with this message. I added manual
  overrides for all plymouth jobs in /etc/init/ but I am tired of
  telling each user how to work around a problem.

  There were suggestions that this is because of kernel cmdline: "cros_secure console= console=tty1 printk.time=1 quiet nosplash rootwait root=/dev/mmcblk0p7 rw loglevel=0" because plymouth only takes first one while kernel is using the last one...
