speakup and frame buffer?

[John G Heim]

Does anybody know if speakup needs a frame buffer? I'm trying to get
speakup working on a machine w/o a video card. It sort of works. I was
taking shots at what the problem was. I installed a package named xvfb
hoping to create a virtual frame buffer. That didn't work but when I
uninstalled it, I got speech until I rebooted. Then no speech again. I
am thinking removing the package, xvfb, recreated some frame buffer
thing which lasted until I rebooted.

I sent my suggestion before I saw this. To answer your question, if a
machine has a physical video card, speakup will work very happily
without a framebuffer. However, if there is no physical video card,
and something needs to read the contents of a screen, then a
framebuffer is the way to do that as far as I know. Do you have
speakup in the kernel itself, or as modules? If as modules, then are
they being loaded in something like modprobe.d, or later on in
something like rc.local? If they're being loaded earlier, then the
framebuffer may not be available yet. I seem to recall the framebuffer
comes up rather late in dmesg.

I now think my problem must be with the speakup_ltlk module. I compiled
a kernel with the "return null" line commented out. So the speakup_ltlk
module loads. And it even works sometimes. I'm not sure what I did to
make it work for a while there. Mostly I just get silence from the
hardware speech synth. Sometimes it speaks random characters.
