How to have numbered equations using KOMA scripts.

Hi everyone
i found that lyx is an excellent tool for writing for academics papers,
however, while i am pretty satisfied with the floating tables, and
floating pictures, i still couldn't find a way to have all my equations
numbered (not showing in the summary but just numbered)
Most of the time i just put an equation or two in between my writing, i
do using the Math display function, so i end up with a nice equation
centered in the page, but that is not numbered...
i would like it will be automatically numbered according to the part,
chapter and so on..
is that possible?
Thanks
Agostino

At the end of the equation insert a label, Insert->Label or use the
shortcut on the toolbars.

Changing the format to number per chapter is easily possible. Just
google for the koma script documentation and read through it. I don't
remember what the command is. Anyways, if you're using koma-script it
would be good to read the documentation (which is very good by the
way).

Problems printing and exporting

Hi there,

Well I've been reading/studying the guides that come together with Lyx, and
so far I think it's a great piece of software, there is a but, though, not
only I'm a newbie to Lyx but also to Linux, specifically to Kubuntu. and I
found really hard to keep up how to install and set up everything, the worst
part is that you don't even bother saying it! you go as far as saying
something like "in this tutorial we are going to assume that Lyx is working
perfectly (why would it?) as well as LaTeX, xdvi, dvips" and then you say
that if this is not the case then I'll have to do it by myself (!?).
I believe that stuff like this is what pushes people away from using great
open source software... specially newbies like me. I know... we can always
google anything but it seems that even though there is an official website
TeX software, it should be included there"... why don't you include
everything that Lyx needs to be perfect?? then there seems to be a way to
link all these pieces of software, that  is, make them work together, but
never mention how to do that...

Now regarding exporting and printing... in every single document I've made
with Lyx.... If I try to do one or the other a message like this pops up...

Hello René,

I can feel the frustration that we have all felt, and I am not certain that I
know enough about Kubuntu or Ubuntu to write anything helpful, but obviously
you need to know a little about what you need to print.

You need the gs package to print from LyX, but you may need another packages
as well. I actually print from xpdf or kpdf after converting the file to a
PDF.

You won't see a .pdf file if you don't have a PDF viewer installed, so again
something like xpdf will do the trick. Once installed Lyx will probably find
it if you close down or reconfigure first and close it down.

Linux philosophy is an operating system that doesn't just install everything,
but you can if you want. It is an operating system where you may exercise
choice. Not a great deal is forced on you even in Kubuntu/Ubuntu, so you
install what you think you need or want, or everything that's available if
you have the harddrive space and don't worry about the security issues. Then
everything will work. Very few people choose the road to bloated bother, and
rather just install things as they are required. So you will have to make
choices and install what you want/need. That's pretty normal when you need to
make a choice in life and just like in life you need to look about to see
what's available to perform the task.

Problems with equation numbering


Hi,

I want to have my equations numbered like (section.formula) so I put the
comand

\numberwithin{equation}{section}

in the preambule. I did in a document and it worked.
My problem is that now, I created a new document and it doesn't work. It's
the same type (article) and I write exactly the same thing in the preambule
but in one document it works and in the other I got the error message:

\numberwithin
{equation}{section}
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., \hobx'), type I' and the correct
spelling (e.g., I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

and

\numberwithin{e
quation}{section}
You're in trouble here.  Try typing  <return>  to proceed.
If that doesn't work, type  X <return>  to quit.

If someone knows what I might be doing wrong. I'm new in LyX and I cannot
fix it.

You have to turn on numbering. Have a look at the new math manual that comes with LyX 1.5.4 to see
the different ways how this can be done.

Use the preamble command
\numberwithin

You have to turn on "amsmath": Menu Document -> Settings -> Math Options -> "Use AMS math package"

It worked for you in the other document as LyX loaded the amsmath package automatically as you used
amsmath stuff that is directly suppoerted by LyX. \numberwithin is not yet directly supported.

This is supposed to be handled for you by Kubuntu: When you install LyX,
the Kubuntu package manager should install everything that is necessary
to get LyX working correctly. If it's not doing that, then that is a
problem with Kubuntu, not with LyX.

First, because there isn't actually such a thing. Take TeX for example.
There are many "distributions" of TeX, and on Linux there are two that
are very widely used: tetex, which is actually unmaintained now but is
still used in Fedora 8, and TeXLive, which is found in many new
distributions. You might have had one of these installed before LyX was
installed, in which case LyX doesn't need to install TeX, and in fact

And I do the same sort of thing: View>DVI, and then print from your DVI
viewer. I want to see the thing before I print it anyway, so this isn't
an extra step.

Re: Including alternate text for figures on HTML export

Given the lack of response I assume there is no easy answer to this,
however, with help elsewhere it seems that this can be done with
tex4ht which is part of the Mactex distribution.

This is done with one of the following commands

1	 \Picture[replacement-for-textual-browser]{file-name attributes}
2	\Picture+[replacement-for-text-browsers]{file-name attributes}
content\EndPicture
3	\Picture*[replacement-for-text-browsers]{file-name attributes}
content\EndPicture

1. what program does lyx use for the HTML conversion (on the Mac), I
presume it tells me on the wiki somewhere but I can't find it.

2. I have tried several ways of using command 1 above to try and add
the alt text into the graphics latex options, but get compile errors.
the commands are obviously meant for tex4ht, but I thought I would
give it a try..

3. Assuming tex4ht isn't one of the two HTML export options in Lyx,
