I've been having trouble finding out the text-mode resolutions of
video cards. Does anyone know of a good compilation of that
information?

Here is a list of modes:
http://en.wikipedia.org/wiki/VESA_BIOS_Extensions#Linux_video_mode_numbers

I think any card that supports VESA probably has to support
1280x1024 and 24 bits (see the table higher up on that page)

Actually, I was talking about text-mode resolutions (as I wrote
above), not graphics-mode resolutions.

Ok, I found it in that Wikipedia article:

Modes 264-268 (vesa's numbers, not the kernel's) are text modes.
264 (0108h) is 80x60, 265 (0109h) is 132x25
266 (010Ah) is 132x43, 267 (010Bh) is 132x50
268 (010Ch) is 132x60.


Relatedly, are they any good tutorials on switching from using
hardware text-mode for non-X virtual consoles to using ... um ...
whatever the name is of the feature of having textual virtual
consoles generated using hardware graphics mode?

Framebuffer? I am not sure I understand what you are asking,
but I think you want your VTs to use higher resolutions and be
graphics capable

Yes, in my virtual consoles I want to see text in a higher
resolution that the video card can provide in hardware text mode.

Thanks.


If that is what you mean, you need to edit your grub menu.lst
file and add to the kernel line a reference like vga=791

Is that number (791) a mode specific to frame buffers, or was it
just an example?

Well, I use the framebuffer @ 791. I have never heard of the
vga=10 that you mentioned. All the modes I have seen are over 700.
I guess the lower ones are text modes (not sure how they relate
to vesa's numbers).

The Debian kernels have the framebuffer drivers compiled in, so
I would just try vga=791 and see if it gives you what you want.

You also mentioned speed. I don't know how fast your computer
is, but I have used 791 on a P3 @ 700 MHz and it was fine.
