[Bug 850895] Re: [nouveaufb] Plymouth refuses to show on boot, only at shutdown (mountall error messages)

[Steve Langasek]

WarriorIng64,

>From the context of your AskUbuntu thread, I understand that the root
issue here is a mismatch between your video card's preferred VBE mode
(as returned by the 'vbeinfo' command in grub2) and the modes supported
by your external monitor.  If you are seeing the splash at shutdown but
only see the "No signal" error during startup, followed briefly by the
mountall message and then X, there are a couple of different
possibilities.

 - the nouveaufb kernel driver may be using the preconfigured resolution passed to it by grub.  If so, this is arguably a bug in the kernel driver; it should instead be probing with EDID to find a resolution supported by the external monitor.
 - the kernel driver may be fine, but plymouth is starting so late that it doesn't matter because you never see it on startup (bug #540801).

Please try the following and report back the results:
 - run 'echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/framebuffer && sudo update-initramfs -u', then reboot.  If you then see the plymouth splash on startup, this confirms that you're seeing bug #540801.
 - boot with plymouth:debug=file:/var/log/plymouth-debug.log added to your kernel commandline and attach the resulting log file to this bug.
 - check the configuration used in X with 'xrandr', and configure grub to use the same mode by setting GRUB_GFXMODE in /etc/default/grub and running update-grub.

Title:
  [nouveaufb] Plymouth refuses to show on boot, only at shutdown
  (mountall error messages)

Status in “plymouth” package in Ubuntu:
  Confirmed

Bug description:
  On my system, Plymouth shows properly on shutdown, but at boot I get a
  blank screen and an error from my monitor saying "No Signal", followed
  usually by some terminal text mentioning something like "mountall:
  Plymouth command failed".

  Then the Unity greeter comes up and everything after that runs just
  fine. It'd still be nice to see the boot splash, though.

  I've been getting this problem since I installed the 9/9/2011 daily
  build of Oneiric, but didn't get around to reporting it until today
  for some reason. Not sure if it's related to the fact that I cannot
  get grub to display either, despite this being a dual-boot between
  Oneiric and Natty, but I'll file that separately.
