Well, the problemis, I don't know the correct parameters to get the best
resolution -- there is a formula to calculate if I use vga=, but grub
had a way where you specified the mode and it put the screen in graphics
mode and passed it on to linux, which seemed unique to me.

  You should be able to pass the kernel parameters in lilo using the
"append" command.  Here's an example from my lilo.conf...

image = /boot/kernel.production
root = /dev/sda5
label = Production
read-only # read-only for checking
append = "noexec=on net.ifnames=0"

So, how do I load a frame buffer module and get it to work?  I tried
creating the device /dev/fb0 by hand, but that didn't help either.  I
may try an alias, but if anyone knows that would be better -- my google
search did not produce anything.

I'm sure there are xorg and graphics experts on this list more suited to
answer this than me, but they would likely need a lot more information
on your installed applications to fully answer.

A good place to start would be the Arch Linux Wiki on nouveau [1], which
seems to indicate some mesa packages would be needed for opengl support.

Yep, I tried that, but no joy there at all.  I even tried the nvidia
frame buffer thinking it might be compatible with the nvidia drivers,
but I could not get anything out of it, either as a module or built in.

Have you tried to load uvesafb module with desired parameters before
running fbset? You can setup modules init script to do that
automatically.

But, if I compile uvesafb as a module, as opposed to having it built
into the kernel, I can never activate  the frame buffer, I always get
/dev/fb0 no such file or directory when trying to use fbset.  If I could
do that, and get the correct mode, that would also solve my problem.

You are, the fact that nouveau is an alternative to the nvidia binary
drivers. I have an Nvidia card on this computer and haven't used the
binary drivers in years, avoiding the various problems that keep popping
up here and elsewhere.

I'm not a gamer (unless you count kpat) and don't need ultimate 3D
acceleration, nouveau suits my needs perfectly, especially the need for
things to just work.

That's why I said "switch to nouveau", using that instead of the binary
drivers should avoid the conflict.

It is possible to use nouveau driver instead of nvidia drivers.
nouveau is a free software, it is also compatible with linux
framebuffer drivers (if I remember this correctly), but 3D
acceleration will be poor to broken compared to the propietary
nvidia drivers, as well as some other features (like advance power
management, cooling states and so on).

Results vary depending on a hardware used, but usually nouveau is
sufficient when user needs only office, web or video and is
unacceptable when user needs 3D-related stuff (gaming, modeling,
etc).

The nvidia drivers are the proprietary drivers produced by NVIDIA; the
nouveau drivers are the open-source version.  Typically, the nouveau
driver works as well as the nouveau, except in some high-intensity
(generally 3D) environments.  As you know, you cannot use both at the
same time, but you can have them installed at the same time.  Just
blacklist the kernel modules of one or the other to test each.

You can pass any kernel parameters using lilo as well.

Also it should be possible to use uvesafb and nvidia driver without
kernel switch, at least this is possible with fbcon: as described
in [1], it is possible to unbind framebuffer console and use text
vga console, then you should be able to unload uvesafb module and
load nvidia propietary blob.

You can't use the nouveau drivers and the nvidia driver at the same
time, so this is the problem.  I did try that once, but at the time
which was quite a while ago, it didn't work.

Might it not be simpler to avoid the conflict by switching to the nouveau
drivers rather than trying to learn a new bootloader just to pass a
workround?

Well, I am trying to use the nvidia driver which conflicts with uvesafb
frame buffer, so it seems.  It used to work fine, but not it does not
work anymore and the only solutions I have found was a couple of grub
parameters which gives you a higher resolution and passes it on to
linux.  It would not be as good as the uvesafb, but at least it would be
better than 80x25.  I use the console a lot and only use gnome
sometimes, but I don't want to have to reboot into a different kernel
just to use gnome.

So, I thought I would check out grub2 to see if those parameters would
work for me or not.

The commands that show up in "qlist grub" can be run from a standard
shell. The GRUB interactive shell is different, with its own set of
commands. You really need to read the online manual or the info pages
again. The man pages explain the individual commands, but only the full
manual shows how it all fits together.

Why are you looking to switch from Lilo to GRUB now? If Lilo works, stick
with it. If it is because you have EFI hardware, I'd skip GRUB and go
straight to Gummiboot or systemd-boot.

hmmm, I thought you could do it from the console as well, for certain
commands.

If not, I will check further.

That's the GRUB interactive shell, that you get to from the boot menu
(press c) or get dropped into it if there is no grub.cfg file.

But the manual and the html pages constantly talk about the grub command
or rather the grub interactive command, and they usually call it grub,
maybe it has a different name.
