This is a simple viewer for latex-beamer presentations that are built with the show notes on second screen option of latex-beamer.

It will take your PDF file, split it in a left and right half and render the two halves individually to the screens.

There is a manpage included that explains all the options and keybindings. Most important ones are probably:

Command line:

dspdfviewer [options] pdf-file

where the most useful option is probably -f, because it enables you to use the software with a standard pdf (i.e. not specifically built for latex-beamer).

In-Program-Controls:

Left/Right, Mouse Buttons or Mouse Wheel: Back/Forward

S/F12: Swap screens (if you see the wall clock on the projector)

Q/Esc: Quit

If you are using Debian wheezy or sid, you should be able to get a binary from my repository:

http://danny-edel.de/deb/

If you open the link with a web browser, there are some copy-and-paste instructions on how to add the repository. These packages are built by myself.

For Ubuntu Oneiric (11.04) and newer, there are two PPAs configured: A "daily" repository and a "release" repository. Use the daily builds only if you want to help in development (test bugs in the latest git revision), otherwise stick to the "release" PPA:

1. Daily https://launchpad.net/~dannyedel/+archive/dspdfviewer-daily
2. Release https://code.launchpad.net/~dannyedel/+archive/dspdfviewer

You need the "devscripts" debian package installed to build from source.

1. (once) git clone git://github.com/dannyedel/dspdfviewer.git
2. (update) cd dspdfviewer; git pull
3. (build) debuild -tc (note: this step will tell you about missing build-deps.)
4. (install) su -c debi (or sudo debi, if you're ubuntu-ish)

You will need a C++11 compiler and the cmake build system.

1. (once) git clone git://github.com/dannyedel/dspdfviewer.git
2. (update) cd dspdfviewer; git pull
3. (make a build directory) mkdir /path/to/builddir ; cd /path/to/builddir
4. (create Makefile) cmake /path/to/sourcedir (note: this step should tell you about missing build-deps)
5. (build) make
6. (install) make install (optional)

If you use a mac with macports, it is very easy to set up a qt4 environment

1. install macports
2. port install poppler +qt4+quartz
3. port install cmake

then follow the normal build instructions
