I realise that "vga=" has been depreciated, but at the time it was the only way I could get grub and the inital boot to use the full screen.
I still use vga=791 in one machine, it was the only incantation that worked properly.
Indeed. Back when I was in 11.x that's what it took to get the grub2 and the initial book to recognise the newly arrived 1280x1024 LG Flatron. Than and an extra set gfxmode=1280x1024 in grub.cfg As you say, it was the only incantation that worked properly. Well, not 'only' But that family and varying the colour depth ...
So I've been playing around this weekend with the "command line" and now without any "vga=" at all it seems to .... if not "work properly" than I have a font I can live with and LINES=48
I emphasise that the "vga=" worked fine until kernel 4.3 or 4.4
This is interpreted by vesafb. So it really sounds like different driver is used now. Can you upload dmesg output immediately after boot with "good" and "bad" kernels?
I've tried looking through change logs but my google-savvy in this area is deficient. So far I've found nothing that shines light on all this. If anyone more familiar with the kernel change process can help, I'd be interested in hearing.
