## I now have LyX working properly, on my Linux tablet.

According to This Earlier Posting, I had installed “GNURoot (Debian)” and “XSDL” on an old tablet, that are both Android apps available from Google Play, and which do not use ‘root’. There were numerous Linux-applications which would run, and many more that do not. I had also installed numerous Linux-packages that can collectively be referred to as “LaTeX” on that tablet, which actually just means by itself, command-line programs. Yet, even when typesetting using ‘LaTeX’, it’s often more fun to use a GUI. And the Linux-application “LyX” is such a GUI.

So, I have the hypothetical ability to do serious document-work on that tablet, even though the tablet is only using an emulated mouse, and “Hacker’s Keyboard”, and the mentioned emulated X-server.

What I recently did, was to get LyX to work properly:

## tex4ht / mk4ht Broken (Problem Solved).

As of 05/26/2018 :

I have just been experimenting with a GUI front-end to LaTeX, that is called ‘LyX’, and it tries to be a WYSIWYG LaTeX Editor.

LyX tries to give editing capabilities for LaTeX documents, using an editor style similar to most word processors. Mind you, this task cannot always succeed 100%, because by its nature, LaTeX will encode the logical structure of a document-to-be-typeset, while conventional word processors try to control the appearance of documents.

And so one feature that LyX does have, is to import and export documents of various formats, most of which revolve around different LaTeX coding-styles, or around ‘rendering’ our LaTeX document to such formats as PDF or DVI, just because those two output-formats have arbitrarily emerged as standard publishing formats. DVI is really only interesting as a legacy Linux graphics format.

And so what some people will want to do, is convert documents from LaTeX either to OpenDocument format, or even to MS Word Format. These formats are initially visible in the Export Menu, if the user has command-line tools such as ‘mk4ht’ installed.

What can frustrate some people who are new to Linux, is that the command-line itself may be defective in some way, meaning that it malfunctions, and in my own experience, trying to get ‘mk4ht’ to work can be futile, when it does not work out-of-the-box. And then, trying to fiddle with the GUI of LyX is also to no avail, because the GUI can finally only work as well as the command-line, back-end that it has detected.

So instead of trying to repair ‘mk4ht’ – which, if it was working, could just as easily be tested from the command-line:


mk4ht oolatex somefile.tex

I would propose that any readers of this blog, who have run into such a problem, and who are running Debian / Stretch, try instead, to install a Debian package called “pandoc”, as well as “pandoc-citeproc”. When LyX recognizes these programs as installed, they will become available as ways to export to or import from .DOCX as well as .ODT formats.

## I’ve just installed LaTeX on my Android / Linux tablet.

In This Posting, I roughly explained how I was able to install Linux on my Samsung Galaxy Tab S.

Since then, the Linux software that I was able to install, and which works, include, among other applications,

• GIMP
• Blender
• LibreOffice (a Comprehensive Install)
• InkScape
• GVim
• MPlayer (Video With Sound)
• LaTeX
• LyX (A Word-Processor based on LaTeX, and not quite WYSIWYG)
• (a Graphical LaTeX Code-Editor)
• ‘Dia’ (a Useful Diagram-Editor)
• Miscellaneous Diagram-Drawing Software (that uses LaTeX as a Back-End)
• wxMaxima (a Computer Algebra System with GUI)
• GNUPlot (Gives 3D Plots)
• Yacas (Yet Another Computer Algebra System)
• ‘mkvtoolnix-gui’ (A video-file concatenation tool)

But, doing so also consumed several GB of storage, even though that tablet only has 16GB of storage. Currently, my Linux guest-system is taking up 4.41GB.
