Comment 2 for bug 884672

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.
