["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Steve Langasek, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc1

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  modeswitch (flash to black) on intel between grub and plymouth

Status in The Ubuntu Flicker-Free Boot Project:
  New
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Even after ensuring I have an up-to-date grub installed with the
  hwcheck license fix (verified from the grub shell at boot time), I get
  a brief clear-to-black between the purple grub screen and the start of
  plymouth.

  Possibly relevant details:

   - plymouth is being started from the initramfs, not from the root system (cryptsetup)
   - I have grub configured to show the boot menu automatically, instead of the default of auto-booting to the first option
   - a plymouth debug log does show that plymouth is successfully using the drm backend, not the framebuffer backend; so this doesn't appear to be plymouth racing the kernel driver initialization.

  Possibly relevant plymouth-debug.log snippets:

  [main.c]                            check_for_consoles:checking for consoles
  [main.c]                            check_for_consoles:There are currently 0 text displays

  [main.c]           plymouth_should_show_default_splash:checking if plymouth should show default splash
  [main.c]                           show_default_splash:Showing splash screen

  Colin says this is unlikely to be a bug in grub given that hwcheck is
  succeeding, so reporting this against the kernel.
