Yes, I guess Ubuntu version of GRUB is slightly modified, and it uses
Plymouth to provide that "nice" (and buggy on some machines) graphic
bootsplash. What I need is to avoid virtual consoles at all, also, I
need one static image visualized by framebuffer, which then smoothly
passes to my GUI app. Even more, being my app Qt based, I think about
throwing away the Xorg server and use Qt's support for framebuffer. So,
it will probably do a nice job. Hope I've explained what I need. For
example, on Android devices how this thing is done? You turn on the
device, and then the loading animation is displayed for a while.
Everything goes smooth, no glitches, and I suppose, there's no Plymouth
:)
