AllowEmptyInput and HAL

My efforts to recover from a dead computer continue. I have
resurrected the old disk in a new box, but the new box has a different
graphics chip and installing the (Debian packaged) driver for that has
brought in new bits of everything, and it has all gone bad.
Specifically, when X started I had no keyboard or mouse. After
power-cycling [no other way to escape!] I found a message in the log
saying that "AllowEmptyInput" was enabled and that my keyboard and
mouse configuration was being ignored. Having looked this up in man
xorg.conf I see that this mode is the default. I'll try to be polite:
This does not seem like the most useful behaviour.
Having set AutoAddDevices to false in order to disable the unhelpful
AllowEmptyInput, I now have a functioning mouse. But I have a keyboard
where every alternate keystroke produces the right letter and the
others produce garbage (maybe top-bit-set characters?).
I also noticed some messages in the log where "config/hal" complained
that "NewInputDeviceRequest failed". Presumably this is because of my
AutoAddDevices. I had noticed that Debian installed "hal"; I had not
previously heard of it. It looks like something that sits on top of udev.
So I've now spent most of three days on this. I just want a computer
that works, preferably as well as the old one did, and while I don't
have one I can't do much work [I'm self-employed]. So could someone
please suggest what I should do:
- Is there some simple set of xorg.conf settings that will make it just
work like it did before, without any AllowEmptyInput and HAL stuff and
with a functional keyboard?
- Or would I be better off trying to learn how this HAL thing works?
X is something that I only have to understand once every few years when
I have some new hardware. By the next time I need to understand it,
either I have forgotten something vital or it has all changed....
