[Bug 884672] Re: boot splash screen displays at incorrect resolution

[Steve Langasek]

It is likely that this is a bug in your BIOS, not in an Ubuntu package,
and that there's nothing we can do about this.  Plymouth can only
display on a kernel framebuffer, and you are using the nvidia binary
drivers, so the only interface we have available is the VESA one.  If
your laptop's VBE doesn't include a 1920x1080 mode, there's no way for
us to put the display in this mode without using a native driver, and we
can't use the native nouveau driver because you've elected to use the
binary nvidia driver instead.

You can check what video modes are available in your BIOS by holding
down shift at boot time to get to a grub menu, pressing 'c' for a
console, and typing 'vbeinfo'.  If there's no 1920x1080 mode there, then
there's nothing we can do.

Reassigning this bug to grub2, which is the package that handles the
VESA setup for us, in case this mode is available in the BIOS and we're
somehow failing to set it.

Title:
  boot splash screen displays at incorrect resolution

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  My LCD monitor's native resolution is 1920x1080, but the Ubuntu boot
  splash is shown at 1280x1024.  As a result, it is horizontally
  stretched.

  Bug #563878 looks like it might be relevant, but it appears to
  document that a fix has been released.  This fix does not seem to
  address the problem for my specific configuration.
