Lyx Change tracking show changes in output not working with displayed equations


I would like to print a hardcopy changes in output (deleted and added).
If what I deleted does not contain a displayed equation, I can export the contents of my lyx file to a pdf file, and then print it out. However, if I delete a displayed equation, then an error message appears during the export to a pdf phase. I've also exported a lyx file to a plain latex file, with the changes in output on. In this case, again I get similar errors. With the changes in output off, latex does not generate errors. 
Is this a limitation of "tracking changes" or an error?
Let me know how to get around this problem.

No graphics preview within LyX

Dear list members,

I have this issue with a PC at work: graphics are not displayed in sh:
1: convert: not found
/usr/share/lyx/scripts/convertDefault.py ERROR
Execution of "convert" failed.the LyX window. I got this error:

"Error converting to readable format"

(I do my best to translate from French.)

However, the graphic file is here, and previewing the whole file (e.g.
in PDF) is fine.

The system is Linux Debian Stable (w/ LyX 2.1.3), it's supposed to be
the very same
setup as on my home PC (except that it's 32-bit instead of 64). My own
PC does not have this problem.

If I launch LyX from the command line, I get this error message in the

sh: 1: convert: not found
/usr/share/lyx/scripts/convertDefault.py ERROR
Execution of "convert" failed.

I suppose some package is missing , but I don't know which one.

TIA for any advice - regards,

Problem with Lyx 2.2.0 Windows Install


I installed Lyx 2.2.0 on a Windows 10 machine and everything worked 
perfectly out of the box. On my 64-bit Windows 7 machine I got an error 
during the installation "platex.exe - entry point not found" which is 
displayed again when I try to reconfigure Lyx (which fails). Basic 
documents compile properly but anything with knitr fails with a "Lyx can 
not convert file" error. Any ideas on how to fix this?

Fwd: Moving around

Perhaps you can repost your example, between pre and /pre tags?



sorry you couldn't see the proper formatting. I repost the formula with the tags inside the formula, so it should be clear

A \frac{1}{2} B  + C \left(1+1\right) D =  2.5 E

I can say that I have exactly the same behavior you describe, in any place. In fact, I also use the cua bind, plus a bunch of personal bindings which, however, are not related to moving actions.

It seems to me that there is some consensus about the fact that moving/selecting could be improved.
Here is what I think. The guidelines should be as follows:


left/right arrow: moves to the previous/next character
ctrl+arrow: moves to the previous/next word
ctrl+home/end: moves to the begging/end of the line
up/down arrow: moves to the previous/next line


shitf+arrow: selects from current position to the previous/next character
shift+ctrl+arrow: selects from current position to the previous/next word
shift+ctrl+home/end: selects from current position to the begging/end of the line
shitf+up/down arrow: selects from current position to the previous/next line

This is actually what really happens when you are in a pure text paragraph.

The problem is how to interpret this inside a formula. I do realize that a formula has a much more complex structure and syntax than a text paragraph, yet what happens now is (to me) quite disconnected from what happens inside a text paragraph and I get very confused when I select inside a formula.

My suggestion is as follows.

Let me put a few more tags:

A \frac{ AA 1 AB }{ 2 } B  + C \left( CA 1 CB + CD 1 CE \right) D =  2.5 E

Moving with (right) arrow is consistent: you go from A to AA then to AB or from C to CA then to CB, CD and CE.

Selecting with arrows should be something close to this. That is, selecting the smallest chunk of code possible.
At present, selecting with arrows has a complete different behavior depending where you are:

- if you are in CA it selects CA-CB  (ok)
- if you are in C it selects C-D  (why? not ok for me)

Ctrl+arrow and shift+ctrl+arrow are inconsistent:
what happens now is that:
- if you are in CA with ctrl+right you go in CE  (ok)
- if you are in C with ctrl+right you go in E   (not ok)
and the same when selecting.
What I think it should happen is:
- if you are in CA with ctrl+right you go in CE  (ok)
- if you are in C with ctrl+right you go in D (a movement that I cannot perform with any combination)
and when selecting:
- if you are in CA with shit+ctrl+right you select CA-CE  (ok)
- if you are in C with shift+ctrl+right you select C-D (that is, the same action that at present is performed by shift+right)

Note also that at present Home and ctrl+right arrow behave _exactly_ the same (and the same for the shifted version): this is a waste of resource in my opinion and even a bit confusing.

I hope to have explained myself clearly (and not have bored you...)

Koma-script letter error

Hi all,

When trying to use the Koma-script Letter template I get this error:\

! LaTeX Error: \begin{letter} on input line 27 ended by \end{document}.


Your command was ignored.
Type  I <command> <return>  to replace it with another command,
or  <return>  to continue without it.

Suggestions on how to deal with this would be most welcome.

Issue with Spreadtab module


One of the documented features of the spreadtab module is the ability to save calculated values (see
section 1.6 of the SpreadtabWithLyx.pdf)

The method described is not working either in LyX 2.1 or 2.2. The instructions say to insert > Short Title
before the table, but it does not exist in these versions, and the source file of the instructions
(SpreadtabWithLyx.lyx) throws an error on section 1.6 when building:

.\label{If-we-wish} It is tempting to put this
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.

Does anyone know if there is currently a way to save cell results for reuse outside the table? This is
important for the situation I’m working with.

Upgrading to Lyx 2.2

When I try to upgrade to Lyx 2.2 using Liviu's ppa, it seems to recognize only Ubuntu version 15.10, and not 16.04 (which is what I am running).  Therefore it fails to find the appropriate file, and fails to upgrade.
What am I missing (or am I being too impatient)?

Follow LyX on Twitter?

Dear LyX users,

In case you are interested, you can follow LyX on twitter at:

We have very few tweets, but it's a nice way in case you would like to
retweet some of our news (like the 2.2.0 release!) to share the
excitement about the new features.

Moving around


when I move around in a file I have a behavior which (to me) does not seem consistent.
Please let me explain.
If I am inside a text portion of the file, arrows drive me to the close by character, ctrl+arrows to the close by word, shift+arrows select close by character and shift+ctrl+arrows select whole words.


What I can't get used to is what happens when I am inside a (big) formula. Namely, if I use ctrl+arrow I go to to the end (or beginning, depending the arrow) of the formula, which is the same that I get using the Home/End keys.
On the contrary, with ctrl+arrow I would like to be driven to the end/beginning of current logical element, that is the same place where the cursor would be if I hit shift+arrow.

So, my question is: can it be changed?
I tried to change some setting in keyboard shortcuts, but without luck. Maybe I could not figure out the right one.

Thank you

Multi-page tables are special. They can have caption. Normal tables do not.
Floats can have caption too.
The feature comes from latex long table. As a GUI for latex, lyx tries to mimic it. Not wrong from my POV.
Besides, it makes no sense to me, using multi-page table inside a minipage.

Odd table numbers


Can somebody help me with the odd table numbers in the attached file (1, 
2, 3, 4, 6, 8?)? It was created with LyX 2.2.0rc1. I don't know what is 
going on.
