What I call the POST? Yes, well in the olden days, when we had real
CRTs, and "everything" ran at VGA resolution, you could sit back for
a minute and watch the whole light show: Graphics card, BIOS, POST,
Lilo, Kernel, and all the dmesg stuff, with the odd screen clearance
but no noticeable change in mode. (I used to scroll back and cut and
paste everything post-POST into an archived file.)

Nowadays, with these fancy flatscreens, each change in mode can lead
to a significant blank period (seconds) while it sorts itself out.

Do you mean that you hear the fan going at full speed? Yes, that's
quite normal AIUI, and seems very sensible: if nothing is monitoring
the temperature of the system, then running the fan is the failsafe state.

Exactly — and if it does, what's printed, and are you aware of
anything that might be missing. Or does it reboot. Or is it still
running, but writing to one of the many serial connections?

Cheers,

And mine stops, period. keyboard dead after reporting its there if I touch a key. once. No further response to anything but the reset button on the front of this huge tower.


Theory is its looking for brltty and will not proceed without it. So until that linkage is found and removed, I can't reboot w/o doing yet another install right now.


It has to be removed entirely before I can reboot again.

Adding "period" is no help. "Stop", on its own, is just so ambiguous.
What exactly stops, the process — or the computer.

In real life, we use the circumstances to decide on the meaning.
If I reported that I "stopped the car" because I saw a ball rolling
into the road, you'd assume I didn't cut the engine. If I said it
was because I saw a dust-devil barrelling down the road, you'd
assume I stopped both the car and engine.

> keyboard dead after reporting its there if I touch a key. once.

Again, I have no idea what this means. None of my keyboards has
ever reported anything, to my knowledge.

Ah, is this because you nuked it (whatever we understand by
the term "nuked")?

If your machine is utterly unable to avoid installing it, perhaps
you'll have to read its documentation in a little more depth and
learn how to prevent it from finding a device to talk to.

Or can you blacklist the snd modules? What do you use sound for
on this computer? Is it essential for its task, which I assume
is something to do with a lathe? Or are you still playing videos,
logging in to your bank, and machining stuff, all on the same
computer? (I realise that's a loaded question.)

Cheers,
David.
