These days, I’m writing more and more in RMarkdown than TeX/LaTeX. But I have to say, if you’ve never used LyX, and want to produce beautifully typeset documents, I strongly recommend LyX. I’m really only looking at the program from an RPI4 perspective. I’ve deliberately tried to avoid this blog post turning into a review of LyX itself. Use that as a barometer for other regular activities. What the graph seeks to show is how long a fairly routine operation takes on the RPI4 compared to 2 Intel machines, both of which are very mainstream. Most of the CPU usage is consumed by pdflatex, not LyX. Instead, it illustrates the time it takes to export LyX’s User Manual to PDF format on 3 different processors including the RPI4’s Cortex-A72 CPU. The chart below is not an attempt to benchmark the speed of LyX on the RPI4. Even with really large documents, you won’t have any issues running LyX on any of the 3 RPI4 models. Frugal! With the project’s tutorial file loaded, this increases to 61MB of RAM, and with the User Guide memory consumption stands at 68.2MB. How’s memory consumption? With LyX open with no document loaded, memory consumption of the program is a mere 52.2MB of RAM. The software never felt sluggish definitely quick enough for most usage. Start up times are quick, about 3-4 seconds from a cold startup. In operation, things are good too. How’s performance of LyX on the RPI4? Pretty impressive in my opinion. Now exporting the PDF proceeded without a hitch. Go to LyX’s menu bar, and select Tools | Reconfigure. But you also need to have Inkscape installed, which was missing from my system. Now LyX has supported SVG images since version 1.6.6. Sadly the export wasn’t plain sailing, with the RPI4 generating the following error dialog box. I usually start with the project’s own tutorial document. One of these tests is to export a document to the PDF format. On my Intel machine with the Arch distribution I get version 2.3.4.3, the latest version, whereas with Ubuntu 20.04 I get version 2.3.4.2.Ī good test of an installation of LyX is to perform some routine functions. You’re missing on substantial development as there have been 3 later releases of the program. That version was released way back in December 2018. And it’ll consume a fair chunk of hard disk space, 406MB of space to be precise. As you can see from the screen image, this command installs a whole raft of other software.
