interesting, I guess that's another way of looking at it. Bear in mind 
though that the cpu really is low powered. On top of that, it's a netbook so
keeping power consumption low is important 


In the meantime I've found that links2 might do what I want as it supports
text and graphics in svga/framebuffer.

thanks for the suggestion

Exactly, I would still use X, just with a frugal wm (dwm).

I wonder if AA-lib is still viable; it was fun to play with back in
the day: :)

You'd earlier said that you couldn't use sc anymore as you couldn't get 
X to work with it - that it lost video when quitting X or switching to 
vtys from X, which presumably is still an issue.

But since tech-lists specifically doesn't intend running X, is there any 
other reason to avoid still using sc(4)?  It's still optional, isn't it?

Tmux or screen will give you an unlimited number of virtual terminals using
only a single TTY. And give you the ability to split the console into
multiple windows.

thanks for the tip. I'll checkout zgv.

Basically I'm looking for the console equivalent of all the
programs one would expect to use on a desktop. So for example,
my favourite email program is mutt. So for mutt, to view a
html email I pipe it through w3m, to view a jpg attachment
I guess I'll need to edit the mailcap file to make it load
zgv. I'm interested in any suggestions the list(s) have
concerning console equivalents of desktop programs.


Still you might be successful finding a viewer that can
directly interface with the "vt" graphics mode...


Yeah that's what I hope. The laptop is AMD C-70 which has an
AMD/Radeon APU. It will run xorg but console mode is much faster
and consumes a lot less power. What's nice about the netbook is
that it's just about the ideal size of keyboard and screen, the
case is high quality glossy black plastic and it has a usb3
port and the video is recognised by radeonkms, which gives a
really nice clear console. The downside is the CPU isn't
powerful, so I need to optimise everything for it, and this
"console-only" idea is part of the optimisation I'm attempting.


Yes. Edit /etc/ttys to spawn more gettys. See "man 5 ttys"
for details.


thanks for this tip as well

Additional thought:

With vt, default text modes are typically much bigger than
the traditional 80x25 of sc. With the "block graphics" and
maybe ASCII art + foreground / background color attributes,
maybe there is a viewer that converts the image into "text
with control characters" that can be displayed directy in
the vt text mode, without using any graphics?

Just a stupid thought... ;-)

Maybe something svgalib-based? With the new console "vt", you
basically are in graphics mode all the time, there is no text
mode anymore (that was "sc"). I know there was an image
viewer called zgv (console) + xzgv (X), with version 0.8_9
being the last usable version (prior to the "library shift"),
but this probably isn't being maintained anymore...

Still you might be successful finding a viewer that can

Yes. Edit /etc/ttys to spawn more gettys. See "man 5 ttys"
for details.

console-only freebsd

[tech-lists]

Hi,

I have a freebsd 11-stable installation on a (gutless) netbook. What I'd like 
is full functionality via the console[1]. One of the things it needs is some 
graphics capability but without xorg. So I'm thinking, svga or libSDL. 
For example, let's say to view a jpg file. If this is possible from the console, 
what program or port would one use to view a gif or jpg file?


[1] by console, I mean the consoles accessed via alt-f1 to alt-f7 [2]
[2] can the number of consoles be increased?

many thanks,
