\begin_layout Section
Introduction and General Information 
\end_layout

\begin_layout Subsection
What is LyX? 
\end_layout

\begin_layout Standard
LyX is a program that provides a more modern approach to writing documents
 with a computer, an approach that breaks with the obsolete tradition of
 the 
\begin_inset Quotes eld
\end_inset

typewriter concept.
\begin_inset Quotes erd
\end_inset

 It is designed for authors who want professional output quickly with a
 minimum of effort without becoming specialists in typesetting.
 The job of typesetting is done mostly by the computer, not the author;
 with LyX, the author can concentrate on the contents of her writing.
\end_layout

\begin_layout Standard
LyX provides an 
\begin_inset Quotes eld
\end_inset

almost-WYSIWYG
\begin_inset Quotes erd
\end_inset

 view of the document.
 
\begin_inset Quotes eld
\end_inset

Almost
\begin_inset Quotes erd
\end_inset

 means that the line- and page-breaks are not displayed exactly as they
 will appear in the printed document.
 However, that's not really necessary, since LyX uses a separate typesetter
 program (called LaTeX) to perform the final formatting of your text.
 While LyX contains everything it needs to be a comfortable user interface,
 the typesetting program contains everything necessary to format text, and
 do so very, very well.
 
\end_layout

\begin_layout Standard
So, line- and page-breaks aren't your problem anymore.
 Remembering which number to use for the next subsection isn't your problem
 anymore.
 Recalling what font you used for all of your section headings isn't your
 problem anymore.
 You tell LyX (and LaTeX) what 
\emph on
kind
\emph default
 of document you're editing and what 
\emph on
type
\emph default
 of paragraph this-or-that text is, the computer can typeset it accordingly.
 Of course you can also still do some low-level formatting for fine-tuning.
 However, the proper way with LyX is to tell the computer what the text
 
\emph on
is
\emph default
, not what it should look like.
 So, we like to say that LyX gives you WYSIWYM editing (What You See Is
 What You 
\emph on
Mean
\emph default
).
\end_layout

\begin_layout Subsection
That's fine, but is it useful?

\begin_layout Subsection
Does LyX run on my computer?
\end_layout

\begin_layout Standard
LyX is known to run on the following platforms (and probably a zillion others):
\end_layout

\begin_layout Itemize
Linux distributions: Debian, RedHat, SUSE, Mandrake, Fedora, Ubuntu, Gentoo,
 etc
\end_layout

\begin_layout Itemize
Microsoft Window NT, 2000, XP, Vista (Windows 95/98/Me editions are not
 supported)
\end_layout

\begin_layout Itemize
MacOSX (starting from 10.1)
\end_layout

\begin_layout Itemize
SparcLinux: RedHat 6.0
\end_layout

\begin_layout Itemize

\end_layout

\begin_layout Itemize
HP-UX
\end_layout

\begin_layout Itemize
OSF1 flore V4.0 1091 alpha
\end_layout

\begin_layout Subsection
How much hard disk space does LyX need? 
\end_layout

\begin_layout Standard
Binary size depends on the system, the LyX binary consumes 13 MB of disk
 space on Windows, while the supporting files occupy another 25 MB (17 MB
 of which is consumed by the docs! You can delete the languages you don't
 care about to save some space).
 Of course, you do need to have something like teTeX installed which consumes
 a mere 115 MB, as well as ghostscript, which is another 10 MB!
\end_layout

\begin_layout Subsection
Is LyX really Open Source? 
\end_layout

\begin_layout Standard
Yes.
 The freely available GUI toolkit that LyX uses, Qt, although a proprietary
 product of Troll Tech, is used in its open source GPL variant.
 The LyX source itself is also available under the GPL, so it qualifies.

\begin_layout Section
Compatibility with other word/document processors
\end_layout

\begin_layout Subsection
Can I read/write LaTeX files?
\end_layout

\begin_layout Standard
Yes.
 LyX outputs LaTeX files that are either machine or human friendly.
 The 
\family typewriter
tex2lyx
\family default
 program that comes with LyX does a decent job of converting LaTeX into
 LyX.
 It's not perfect, but it will usually get at least 95% of the job done
 for you.
\end_layout

\begin_layout Subsection
Can I read/write Word files?
\end_layout

\begin_layout Standard
Not trivially.
 See these page: 
\begin_inset Flex URL

\begin_layout Plain Layout

http://wiki.lyx.org/LyX/ConvertingFromWord
\end_layout

\end_inset

 and also the converters section which will give another possibilities of
 conversion routes: 
\begin_inset Flex URL

\begin_layout Plain Layout

http://www.lyx.org/AdditionalSoftware#toc9
\end_layout

\end_inset

.
\end_layout

\begin_layout Standard
Finally, when all else fails, use any word processor (WordPerfect, StarOffice/Op
enOffice, ...) which understands Word.
 Then export as the file as plain text and add the formatting by hand in
 LyX.
 
\end_layout

\begin_layout Subsection
Can I read/write HTML files?
\end_layout

\begin_layout Standard
You can output HTML files using the 
\begin_inset Quotes eld
\end_inset

tth
\begin_inset Quotes erd
\end_inset

 converter program, amongst others.
 There is a HTML
\begin_inset Formula $\rightarrow$

LaTeX program available (html2latex) which allows you to convert the other
 direction.

\end_layout

\begin_layout Itemize
A PostScript® interpreter: ghostscript 7.0 or higher
\end_layout

\begin_layout Itemize
A modern C++ compiler.
 If you are using gcc, LyX requires at least version 3.2.0.
\end_layout

\begin_layout Subsection
How do I compile it?
\end_layout

\begin_layout Itemize
./configure
\end_layout

\begin_layout Itemize
make
\end_layout

\begin_layout Itemize
make install (usually as root, though you don't have to be if you add flags
 to the configure command)
\end_layout

\begin_layout Standard
See the INSTALL file for more details.
\end_layout

\begin_layout Subsection
I hate compiling.
 Where are precompiled binaries?
\end_layout

\begin_layout Standard
Most of the above packages are available as precompiled binaries in a variety
 of Linux systems, perhaps others as well.
 The LyX binaries are available as RPMS, Windows and Mac installers, plus
 a few other formats and may be obtained from

\begin_layout Section
Questions about Evil Red Text (IMPORTANT!)
\end_layout

\begin_layout Subsection
What is Evil Red Text (aka ERT)?
\end_layout

\begin_layout Standard
ERT (Evil Red Text) refers to raw LaTeX commands which are inserted into
 your LyX document.
 Certain troglodytes in the development group coined this term when they
 complained about the unsightly appearance it leads to in LyX documents.
 The more enlightened among us know that it is extremely useful, even though
 it does qualify as URT (Ugly Red Text), but ERT seems to have stuck.
 
\end_layout

\begin_layout Subsection
How do I enter Evil Red Text?
\end_layout

\begin_layout Standard
Aesthetic arguments aside, many of the answers in this FAQ require that
 you use ERT, so whenever we say 
\begin_inset Quotes eld
\end_inset

insert the following LaTeX code
\begin_inset Quotes erd
\end_inset

, do the following
\end_layout

\begin_layout Enumerate
Click the TeX toolbar button or select 
\family sans
\bar under
I
\bar default
nsert\SpecialChar \menuseparator

\bar under
T
\bar default
eX
\family default
.
\end_layout

\begin_layout Enumerate
Type the command as it is written in the normal way
\end_layout

\begin_layout Subsection
The new ERT inset is really inconvenient !
\end_layout

\begin_layout Standard
A lot of people have been complaining about the ERT inset introduced in
 version 1.2.0.
 However, since there is little hope of to see the old LaTeX font return
 from the grave (it was really a hack), here are a couple of things to ponder:
\end_layout

\begin_layout Itemize
You can collapse the ERT like any other floats by using 
\family sans

Open/C
\bar under
l
\bar default
ose float
\family default
 (bound to

\end_layout

\begin_layout Itemize
You can also set it to 
\begin_inset Quotes eld
\end_inset

inlined
\begin_inset Quotes erd
\end_inset

 by using the properties dialog obtained by right-clicking anywhere in the
 inset
\end_layout

\begin_layout Subsection
Is there an alternative?
\end_layout

\begin_layout Standard
LaTeX commands can also be inserted in the 
\begin_inset Quotes eld
\end_inset

LaTeX Preamble
\begin_inset Quotes erd
\end_inset

, a form in LyX that is inserted verbatim into the LaTeX file which is generated
 during processing.
 This is especially useful for including nonstandard LaTeX packages, defining
 global shortcuts to be used within the document, etc.

\begin_layout Standard
Okay, we are not playing Duke Nukem here! To eliminate widows and orphans
 (first line from a paragraph at the bottom of the page and the last line
 from a paragraph at the top of the page), add the following to the LaTeX
 preamble:
\end_layout

\begin_layout LyX-Code

\backslash
widowpenalty=10000

\end_layout

\begin_layout Subsubsection
How do I insert a fixed amount of horizontal space?
\end_layout

\begin_layout Standard
There are various ERT commands to use: 
\family typewriter

\backslash
enspace
\family default
 (1/2 em), 
\family typewriter

\backslash
thinspace
\family default
 (1/6 em), 
\family typewriter

\backslash

\family typewriter

\backslash
qquad
\family default
 (2 em), 
\family typewriter

\backslash
hspace{
\emph on
length
\emph default

\family default
, etc.
 An 
\begin_inset Quotes eld
\end_inset

em
\begin_inset Quotes erd
\end_inset

 is roughly the width of the letter 
\begin_inset Quotes eld
\end_inset

m
\begin_inset Quotes erd
\end_inset

 in the current font.
 The length argument of the 
\family typewriter

\backslash
hspace
\family default
 command is any valid TeX length; units can be 
\family typewriter
mm
\family default
 (millimeters), 
\family typewriter
cm
\family default
 (centimeters), 
\family typewriter
in
\family default
 (inches), 
\family typewriter
pt
\family default
 (points = 1/72 inch), 
\family typewriter
em
\family default
 (width of letter 
\begin_inset Quotes eld
\end_inset

m
\begin_inset Quotes erd
\end_inset

), or 
\family typewriter
ex
\family default

).
 Examples: 
\family typewriter

\end_layout

\begin_layout Subsubsection
How can I make citations show up as [1,2,3,6] or [1-3,6] rather than [1][2][3][6
]?
\end_layout

\begin_layout Standard
Insert 
\family typewriter

\backslash
usepackage{cite}
\family default
 into the LaTeX preamble.
 Most LaTeX distributions should have this package included.
 LyX supports this package, if you insert multiple citations separated by
 commas into the citation dialog, e.
 g.
 [Smalley_JCP,Jarrold_Sci], instead of just one citation after the other:
 [Smalley_JCP] [Jarrold_Sci].

This is an example of less-than-ideal terminology.
 
\begin_inset Quotes eld
\end_inset

Figure
\begin_inset Quotes erd
\end_inset

 is what I would really call a 
\begin_inset Quotes eld
\end_inset

graphic
\begin_inset Quotes erd
\end_inset

; it basically means insert a picture file.
 
\begin_inset Quotes eld
\end_inset

Figure float
\begin_inset Quotes erd
\end_inset

 is more what one means by a figure in a paper: it includes the graphic,
 the caption, the figure label, etc.
 You should almost always insert a figure float first, then put a figure
 inside that.
\end_layout

\begin_layout Standard
Tables work in the same manner.
 Put a table float in first, then insert the table within that.
\end_layout

\begin_layout Subsubsection
How do I get LyX to put the figure exactly where I want it?
\end_layout

\begin_layout Standard
Select 
\family sans
Layout\SpecialChar \menuseparator
Document
\family default
.
 In the 
\family sans
Float Placement
\family default
 box, type 
\begin_inset Quotes eld
\end_inset


\family typewriter
!htp
\family default

\begin_inset Quotes erd
\end_inset

.
 This tells LaTeX to try really hard to put the figure here first, then
 the top of a page, then on a page by itself.
 This is a global setting: all figure will then obey this rule set.
\end_layout

\begin_layout Standard
If you want to control how each figure behaves, right-click in the figure
 float and you will get a dialog allowing to control the figure behavior.
\end_layout

\begin_layout Subsubsection
What does 
\begin_inset Quotes eld
\end_inset

Too many unprocessed floats
\begin_inset Quotes erd
\end_inset

 mean?
\end_layout

\begin_layout Standard
LaTeX can handle only a limited number of floating elements floating at
 a given time.
 For example, if Figure 4 can't be fit in a good location (using the default
 rules of top of the page, then bottom, then a page of its own) and Figure
 5 comes along, they will both continue to float toward the end of the document
 until a good location can be found.
 If nothing good turns up, they will just be placed at the end of the document.
 If there are too many of these, LaTeX overruns a counter and emits the
 
\begin_inset Quotes eld
\end_inset

too many unprocessed floats
\begin_inset Quotes erd
\end_inset

 error.
 This is not a bug in LaTeX, this is simply too many figures with too little
 text :-)
\end_layout

\begin_layout Standard
The easiest way to work around this is to insert a 
\family typewriter

\backslash
clearpage
\family default
 command somewhere in the document where a pagebreak would be appropriate.
 While a pagebreak would simply start a new page, 
\family typewriter

\backslash
clearpage
\family default
 processes all remaining floats, then begins a new page.
 This may lead to an unsightly stack of figures in the middle of your document;
 you may need to use several 
\family typewriter

\backslash
clearpages
\family default
 to make things balance nicely.

Questions Related to Running LyX
\end_layout

\begin_layout Subsection
How do I convert LyX files to LaTeX from the command line?
\end_layout

\begin_layout Standard
File export was vastly improved in version 1.1.6.
 Simply say
\end_layout

\begin_layout LyX-Code
lyx --export latex <yourfile>.lyx
\end_layout

\begin_layout Standard
and that is all you need to do.
\end_layout

\begin_layout Standard
If you have an older version of LyX, you can use the same syntax if you
 are running X, because it will cause LyX windows to pop up onto your screen.
 If you have the Xvfb command available, you can resort to a deeper level
 of subterfuge (under 
\family typewriter
bash
\family default
):
\end_layout

\begin_layout Standard

\family typewriter
(Xvfb :1 -once -terminate &); rm <file>.tex; lyx -display :1 --export latex
 <file>.lyx
\end_layout

\begin_layout Standard
\noindent
Under csh/tcsh it is simply
\end_layout

\begin_layout Standard

\family typewriter
Xvfb :1 -once -terminate &; rm <file>.tex; lyx -display :1 --export latex
 <file>.lyx
\end_layout

\begin_layout Standard
\noindent
This should work anywhere, whether or not X is actually running.

Questions Related to LyX on Windows
\end_layout

\begin_layout Subsection
Why do the menus and the toolbar flicker ?
\end_layout

\begin_layout Standard
You are probably using the XWin32 X server.
 This is a bug in XWin32: you can work around the problem by disabling the
 
\begin_inset Quotes eld
\end_inset

Use Reserved Colors
\begin_inset Quotes erd
\end_inset

 option of XWin32, and using a color mode other than PseudoColor.

Then RTFM, especially the Tutorial.
 The documentation really is quite good.
 (Besides, I helped write parts of it :-) If you think your problem may
 be LaTeX related, then look in 
\emph on
LaTeX, A Document Preparation System, 2nd Ed.

\emph default
 by Leslie Lamport (1994).
 There are also numerous example files included with LyX.
 Try 
\family sans

 Don't forget we have Tips and Tricks database in LyX wiki.

\begin_layout Subsection
I want to mail someone about my problem.
 
\end_layout

\begin_layout Standard
Send email to the LyX Users list lyx-users@lists.lyx.org.
 If LyX is actually crashing or otherwise non-functional, then try the developer
s' list at lyx-devel@lists.lyx.org.
\end_layout

\begin_layout Subsection
What to put in a request for help.
\end_layout

\begin_layout Standard
Include your version of LyX and a description of what you are trying to
 do, along with evidence that you've actually read the docs.
\end_layout

\begin_layout Standard
If LyX has crashed, include the version of LyX, the operating system, the
 version of xforms (if it seems to be a screen drawing problem), and a precise
 description of the events that lead to the crash.
 The easier it is for the developers to reproduce your crash, the more likely
 it will get fixed.
 If you're brave and like to hack, use gdb to generate a backtrace and include
 the results with your mail.
 If you have no clue what I'm talking about, just describe what you did
 as completely as you can.

Bernhard Iselborn, David Johnson, and Paul Evans were responsible for the
 FAQ through version 0.2.2 which covered LyX-0.10.7.
 The FAQ as of version 0.3.0 was written from scratch and covers LyX-1.0 and
 higher.
 Many people contributed pieces to the current version; Mike Ressler of
 the Doc Team collected them into this file.
