From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Open source PDF viewer with Dual Page feature? (lemmy.ml)

Hello, any recommendations for a libre PDF with support for dual page (with the option to adjust which 2 pages are displayed)? Normally I use MuPDF, but there's a document I would like to read which would greatly benefit from some additional features...

Zathura, which is a lot like MuPDF. Press d to toggle the dual page view.

Edit: My bad, just read the part where you said "the option to adjust which 2 pages are displayed". The dual page view in Zathura will show 2 adjacent pages. When I've needed to do that I've just opened two Zathura windows. Especially with a tiling WM it's practically the same feature.

My use case is a pdf of a book which is meant to be read across two pages - wouldn't work if it's displaying pages 1 and 2 together instead of pages 2 and 3, if you see what I'm saying. Does Zathura allow for that?

Zathura always displays odd pages on the right and even pages on the left. Which is how books are conventionally displayed, ie page 1 is typically recto. I don't think this behaviour can be configured, but if you need pages 2 and 3 displayed together then your book would display correctly in Zathura dual page mode. But if you needed 1 and 2 displayed together I don't think Zathura can do that unfortunately

I'll give it a shot and see if it's compatible. Cheers
