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

[Sebastian Pop]

After "apt-get remove gdm lightdm", I get by default to the command line, and there "startx" crashes the kernel.
>From /var/log/syslog, it looks like a problem in exynos_user_fb_create:

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...
