How To Fix dspdfviewer: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu dspdfviewer is provided by dspdfviewer package.

dspdfviewer is:

This is a specialized PDF Viewing application custom-made for the LaTeX class beamer, specifically the “show notes on second screen=right” option.

To make use of this program, you will need a document created by latex-beamer, and you will need two monitors connected to your computer. They do not need to have the same resolution, not even the same aspect ratio.

This program will split your PDF page in half, and display the left half (intended for the audience) on one monitor (think: a notebook’s VGA output connected to your university’s projector) and it will display the right half (intended for you) on the second screen. Also, on the second screen, you get page thumbnails and status information, like the time since you started the presentation and a “wall clock”.

To fix this problem, we can install more using the command below.

sudo apt-get -y install dspdfviewer

This command might take some time to finish depending on your machine internet connection.

sudo apt -y install dspdfviewer

sudo aptitude install dspdfviewer
