Activate pdf thumbnails for XnViewMP on Ubuntu 24

[Arnache]

Hi.

I get SVG thumbnails but no thumbnail for my pdf images. How do I activate this?

XnViewMP 1.7.2 on Ubuntu 24.04LTS.

In Settings>File list>Custom Filters the AI/PS/PDF "Visible" and "Show as thumbnail" checkboxes are checked
In Settings>View>Filter "Custom" is selected and "AI/PS/PDF" is checked

sudo apt list ghostscript shows:
ghostscript/noble,now 10.02.1~dfsg1-0ubuntu7 amd64 [installed,automatic]
ghostscript/noble 10.02.1~dfsg1-0ubuntu7 i386

In the file browser of Ubuntu (Files, aka Nautilus) the pdf thumbnails show, and the pdf can be opened and displayed (Document viewer, aka Evince).

you can launch the command gs?

[Arnache]

Yes, from a terminal.

> gs

it opens and writes the following in the terminal and opens a white frame:

when using XnView, what do you have as log when selecting a pdf file?

[Arnache]

Thanks for your answer. I could not find the log.

Here is the part of the log that appears when I select a pdf which I randomly chose.
In the text below, I replaced the full path by [...]

is it possible to have the pdf file? so Ghostscript 10.02.1?

[Arnache]

Yes, version 10.02.1 on Ubuntu 24.04 LTS

Very good point to suspect the pdfs: I did not realize that it seems to only fail for pdfs that I recently produced (I made a lot of illustrations in the recent months). They are produced by various recent versions of Inkscape, including 1.2.2 and Inkscape 1.4-beta (62f545b, 2024-04-22). It shows well under every viewer, including gs called from a terminal. I joined one to this message (if I understood how to attach files in this newsgroup) that I just created with Inkscape 1.2.2.

other PDFs work?

[Arnache]

Yes, this one for instance works.
