Is there a way increasing boot screen resolution and make fonts appear smaller? After installing nVidia proprietary drivers the console font during boot (after grub2) is huge on my 32" 4K monitor. And the cute little Tux:es are just counting to 11 (of 16)
I have read about KMS and nVidia but don't know if it's related at all.

My system:

This, among other things, is the cost of using the nvidia blob. Your only options are to not use the proprietary driver, or to use hardware that supports Linux properly.

Thank you. I understand. No biggie.

To save you wasting time, because there's a lot of outdated hacks for this on the internet: it sounds like you already have the UEFI framebuffer driver (with plain VGA you wouldn't see the logos at all). It's probably running in 1024x768, which isn't great, but that's as good as it's possibly going to get.

Actually, this can be accomplished with a little effort with uvesafb even with nVidia hardware. Check out the linked Gentoo Wiki article.

In addition to 'uvesafb', the somewhat more simple-like 'vesafb' (CONFIG_FB_VESA) works as well, at least for me. It's very much unsupported however, and indeed, it sometimes breaks...

For a list of available modes one can set 'vga=ask' on the kernel command-line.

Huh yes, please using not uvesafb with newer nvidia-drivers versions - it breaks strong.
Try better efifb ( CONFIG_FB_EFI=y )
